Version: 2.4
2.3 Appropriate use
The servo drives of the AX5000 series are exclusively designed for torque, speed and position control of
suitable asynchronous and synchronous three-phase current motors. The maximum permissible effective
motor voltage must be at least equal the effective mains voltage fed into the servo drive.
The servo drives from the AX5000 series are designed for installation as components in electrical systems or
machines and may be operated only as integrated system components.
WARNING
Caution - Risk of injury!
Electronic equipment is not fail-safe. The machine manufacturer is responsible for ensuring
that the connected motors and the machine are brought into a safe state in the event of a
fault in the drive system.
The servo drives may only be operated in enclosed control cabinets and in accordance with the conditions
described in the "Technical data" chapter.

2.3.1 Dual Use (EU 1382/2014)
According to EU Regulation 1382/2014 (published on 30.12.2014), standard frequency converters, including
the Beckhoff AX5000 product range, are now classified as dual-use products. The list of goods in Annex I of
Dual-Use Regulation 428/2009 was amended accordingly; frequency converters (listed under item 3A225)
with an "operating frequency greater than or equal to 600 Hz" are now subject to export control. Note the
following changes.
Firmware versions without the supplement (Dual Use compliant) can only be operated on the following
devices, taking into account the hardware versions:
• HW Version 1.0 (AX5xxx-0000-00xx): serial number < 68.000
• HW Version 1.0 (AX5xxx-0000-001x)
• HW Version 2.0 (AX5xxx-0000-02xx): serial number < 140.000
• HW Version 2.0 (AX5xxx-0000-021x)
Firmware versions with the supplement (Dual Use compliant) can continue to be operated on all devices,
irrespective of the hardware versions. These versions support both rotary field frequency ranges (< 600 Hz,
>= 600 Hz), depending on the device.
Devices with optional ID “001x” and "021x": shipping as individual part may require official approval.

4.2 Special safety notes for servo drives
The safety instructions are designed to avert danger and must be followed during installation,
commissioning, production, troubleshooting, maintenance and trial or test assemblies.
The servo drives of the AX5000 series are not designed for stand-alone operation and must always be
installed in a machine or system. After installation the additional documentation and safety instructions
provided by the machine manufacturer must be read and followed.
WARNING
Serious risk of injury through high electrical voltage!
• Never open the servo drive when it is live. Wait until the DC link capacitors are dis-
charged. The measured voltage between the terminals "DC+ and DC-" and "RB+ and
RB-" must have dropped below 50 V. Opening the device (with the exception of expan-
sion card slots) invalidates all warranty and liability claims against Beckhoff Automation
GmbH & Co. KG.
• Negligent, improper handling of the servo drive and bypassing of the safety devices can
lead to personal injury or death through electric shock.
• Ensure that the protective conductor is connected properly.
• Disconnect the servo drive from the mains supply and secure it against reconnection
before connecting or disconnecting the pluggable terminals.
• Disconnect the servo drive from the mains supply and secure it against reconnection
before working on electrical parts with a voltage > 50 V.
• Due to the DC link capacitors, the DC link terminal points "ZK+ and ZK- (DC+ and
DC-)" and "RB+ and RB-" may be subject to dangerous voltages exceeding 875 VDC,
even after the servo drive was disconnected from the mains supply. Wait 5 minutes for
the AX5101 - AX5125 and AX520x; 15 minutes for the AX5140/AX5160/AX5172; 30
minutes for the AX5190/AX5191; 45 minutes for the AX5192/AX5193 after disconnect-
ing, and measure the voltage at the DC link terminal points "ZK+ and ZK- (DC+ and
DC-)". The device is safe once the voltage has fallen below 50 V.
WARNING
Serious risk of injury through hot surfaces!
• The surface temperature may exceed 50 °C, resulting in a risk of burns.
• Avoid touching the housing during or shortly after operation.
• Leave the servo drive to cool down for at least 15 minutes after it is switched off.
• Use a thermometer to check whether the surface has cooled down sufficiently.
WARNING
High risk of injury through uncontrolled movements!
• Read and take note of chapter "Important information for commissioning" each time be-
fore commissioning the AX5000
CAUTION
Personal injuries
• Carefully read this manual before using the servo drive thoroughly, paying particular at-
tention to the safety instructions. In the event of any uncertainties please notify your
sales office immediately and refrain from working on the servo drive.
• Only well trained, qualified electricians with sound knowledge of drive equipment may
work on the device.
• During the electrical installation it is essential to ensure that the correct fuses/protective
circuit breakers are used between the mains supply and the servo drive. Further infor-
mation can be found in the "Electrical installation" section.
• If a servo drive is installed in a machine it must not be commissioned until proof of com-
pliance of the machine with the latest version of the EC Machinery Directive has been
provided. This includes all relevant harmonized standards and regulations required for
implementation of this Directive in national legislation.
Safety
Servo Drives AX500020 Version: 2.4

• During installation it is essential to ensure that the specified ventilation clearances and
climatic conditions are adhered to. Further information can be found in the "Technical
data" and "Mechanical installation" sections.
• If the servo drive is operated in contaminated ambient air, the cooling openings must be
checked regularly for blockage. These checks should be carried out several times per
day.
• The servo drives contain components at risk from electrostatic discharge caused by im-
proper handling:
ðPlease ensure you are electrostatically discharged before touching the servo drive
directly.
ðAvoid contact with highly insulating materials (synthetic fibers, plastic film etc.).
ðPlace the servo drive on a conductive surface.

7 Technical description
7.1 Configuration of the servo drives
The servo drives of the AX5000 series are available as single- or multi-channel versions and are optimized in
terms of function and cost-effectiveness. Integrated control technology supports fast and highly dynamic
positioning tasks. EtherCAT as a high-performance system communication enables ideal interfacing with PC-
based control technology.
The single-channel AX51xx servo drives are designed for rated motor currents up to 170 A.
The AX52xx two-channel servo drive enables operation of two motors with identical or even with different
capacity, up to a total current of 12 A. The multi-axis drives with variable motor output allocation optimize
packaging density and the cost per drive channel.
The AX5000 system enables simple and fast connection of several AX5000 devices to form a multi-axis
system through the AX-Bridge quick connection system. The pluggable supply and connection module
combines power supply, DC link, and control (24 VDC) and braking voltage.
A wide range of motor types can be connected to the AX5000. Motors of different size and type can be
connected without additional measures. Examples include synchronous, linear, torque and asynchronous
motors. The multi-feedback interface supports all common feedback standards.
such as: OCT, BiSS, EnDat, 1 Vss, Resolver.
The AX5000 was developed specifically for the EtherCAT real-time Ethernet system. The outstanding
features of EtherCAT are particularly beneficial for drive technology. They include short cycle time,
synchronicity and simultaneity. EtherCAT enables very short cycle times, even in networks containing a large
number of devices.

Servo Drives AX5000 39
Version: 2.4
7.4 Properties
• High-speed EtherCAT system communication
• Wide voltage range: 1 x 100-10% VAC - 1 x 240+10% VAC … 3 x 100-10%VAC - 3 x 480+10% VAC
• Multi-feedback interface
• flexible motor type selection
• scalable wide range motor current measurement
• High-speed capture inputs
• Diagnostic and parameter display
• integrated mains filter
• Optional safety functions: restart lock, intelligent TwinSAFE safety functions
• compact design for simple control cabinet installation
• AX-Bridge - the quick connection system for power supply, DC link and control voltage
The integrated, fast AX5000 control technology with a current control cycle of up to 62.5µs supports fast and
highly dynamic positioning tasks. The drives are designed as single- or two-channel servo drives:
•AX51xx: single-channel servo drive
rated motor current: 1 A, 3 A, 6 A, 12 A, 18 A, 25 A, 40 A, 60 A, 72 A, 90 A, 110 A, 143 A, 170 A
•AX52xx: two-channel servo drive
rated motor current: 2 x 1 A, 2 x 3 A, 2 x 6 A (with flexible allocation of total device current on both
axes)
The 2-channel servo drives with variable motor output allocation enable operation of two motors with
identical or even with different capacity on a single servo drive. For example, an asynchronous motor with a
rated current of 1 A and a linear motor with a rated current of 9 A can be operated with a servo drive with two
6 A channels. The total current is relevant for the device utilization.
The AX Bridge (only up to AX5140) enables convenient and fast connection of several servo drives of the
AX5000 series to form a drive system. This pluggable supply and connection module combines power
supply, DC link and control voltage (24 VDC) and enables fast installation and commissioning.
The AX5000 offers flexible and universal connection options. It supports
• almost all feedback systems, including robust resolvers via OCT, sine/cosine encoders with EnDat,
Hiperface or BiSS.
• a wide range of motor types such as asynchronous, synchronous, torque or linear motors.
7.5 Wide voltage range
In order to facilitate worldwide application with different voltage systems, the AX5000 features a wide voltage
range. Virtually any voltage system can be connected with one and the same device, from 1 x 100 VAC - 1 x
240 VAC to 3 x 100 VAC - 3 x 480 VAC. This reduces stock-keeping and prevents destruction through
unsuitable mains voltage. Examples for different mains systems:
• 1 x 100 VAC, 3 x 200 VAC for Asia
• 1 x 115 VAC, 3 x 230 VAC, 3 x 480 VAC for North America
• 1 x 220 VAC, 3 x 380 VAC for China
• 1 x 230 VAC, 3 x 400 VAC for Europe
Technical description
Servo Drives AX500040 Version: 2.4

Before implementation a DC link group, please contact your UL approval body and discuss
further necessary boundary conditions.
Dimensioning of the UL fuses FDC1-FDCn
The dimensioning of the fusesFDC1 to FDCn in the DC link is application-dependent. The motor and the load
profile are incorporated directly into the calculation. Please consider this when dimensioning.
Fuse holders with UL approval
Note when using UL fuses that the necessary fuse holders also have to carry UL approval.

Servo Drives AX5000 51
Version: 2.4
Mains choke
To ensure balancing of all servo drives, a common mains choke (Lo) must be provided. The rated current of
the mains choke must be ≥ the rated current of the common mains fuse (F0) of the drive system (see section
"Mains fuse"). The short-circuit voltage Uk of the mains choke must be 2%
Dimensioning the mains fuse
The following section describes the dimensioning of the mains fuse to be used for individual devices and the
use of mains fuses in the DC link group.
Series AX5160 to AX5193 (60 A to 170 A):
Individual device:
• The main fuse must be dimensioned such that it corresponds to the rated current of the servo drive
multiplied by the correction factor 1.1. The value determined is rounded up to the next larger standard
step (see section Electrical Data [}35]). If the size of the current (in your application) on the mains side
is known, the mains fuse can also be dimensioned smaller in accordance.
• The cross-section of the mains supply cable must be dimensioned such that the permissible current
load of the cable is ≥ the rated current of the selected mains fuse (see section Motors and Cables
[}105]).
DC link group:
• The common main fuse (F0) must be dimensioned such that it corresponds to the sum of all the rated
currents of the servo drives multiplied by the correction factor 1.1. The value determined is rounded up
to the next larger standard step (see section dimensioning example). If the size of the current (in your
application) on the mains side is known, the mains fuse (F0) can also be dimensioned smaller in
accordance.
• The cross-section of the mains supply cable must be dimensioned such that the permissible current
load of the cable is ≥ the rated current of the selected mains fuse.
• The cross-section of the mains supply cable and the mains fuses (F1 to Fn) of the individual servo
drives in the DC link group are to be selected analogously to the operation of the individual servo
drives (see section "Individual devices").
The local regulations and the local conditions (ambient temperature, cable routing, etc.) must be referred to
when determining the permissible current load of the cables (selection of the necessary cross-section – see
section Motors and Cables [}105]).
Dimensioning example:
1 x AX5172 + 2 x AX5192 + 1 x AX5193
72 A + 286 A + 170 A = 528 A x 1.1 = 581 A 630 A selected
Electrical installation
Servo Drives AX500052 Version: 2.4
Mains switch-on conditions:
The mains must be switched through to all servo drives simultaneously. Therefore, use a common mains
contactor (K0) for all servo drives. The phase error detection (grid monitoring) of the servo drives must be
active. Observe the relevant parameterization for this (P-0-0204 Disable Umain monitoring and Umain phase
error detection).
Parameterization P-0-0204:
The default values of the parameter P-0-0204 (Power management control word) are set to:
• Disable Umain monitoring = 0 and
• Umain phase error detection = 1.
In the DC link group the default values of the parameter P-0-0204 are to be checked before commissioning
and set to the above values if discrepancies are found.
Parameterization P-0-0214:
To parameterize an AX5160 to AX5193 DC link group, the following settings must be made in parameter
P-0-0214 (DC link connection mode):
• The value 0x000A sets the servo drives AX5160 to AX5193 to stand-alone mode
• The value 0x000B sets the servo drives AX5160 to AX5193 to DC link group mode
The external brake resistor is activated in both cases.
Mains filter:
If mains filters are used, a separate mains filter must be used for each servo drive. The mains filter must be
positioned as close to the servo drive as possible. Use short cables without loops.
A suitable shield connection is ensured by adhering to the following points:
• The mounting plate must not be painted. The shield is automatically connected via the mounting plate.
• If the mounting plate is painted, the shield must be connected via the underside of the servo drive
(earthing bolt).
Max. cable sizes accepted by the connecting terminals:
The maximum cable cross-sections are dictated by the maximum cable sizes that can be accepted by the
connecting terminals on the servo drive (see table below):

Dimensioning of the brake resistors for operation in the DC link group:
In individual braking situations the energy balance in the DC link group can be generative. Servo drives from
the series AX5160 to AX5193 have no internal brake resistor. External brake resistors must be used to
dissipate the energy generated. The brake resistor must always be connected to the connector provided on
the servo drive.
Under the following conditions it is possible to dispense with one or more brake resistors:
• the remaining brake resistors must be able to handle the continuous power
• the remaining brake resistors must be able to handle the short-term power
• the ohmic value of the brake resistor for each servo drive must not be lower than the minimum
permissible value.
Part of the brake energy is also stored in the DC link, independent of the brake resistor. The more servo
drives there are in the DC link group, the larger the storage capacity. It is therefore possible to store more
energy.
The following must be considered when dimensioning the brake resistors:
• The external brake resistor must have an ohmic value that is at least as large as the minimum value
permitted by the servo drive.

Min. brake resistor
(external brake resistor)
13Ω 13Ω 10Ω 10Ω 6.5Ω 6.5Ω
• The peak braking power of the DC link group is given by the sum of the peak braking powers of all the
brake resistors in the DC link group:
• The continuous braking power is derived from the calculation of the effective braking power:
where:
Ppeak_Br_DC is the peak braking power of the entire DC link group and
Peff_Br_DC is the effective braking power of the entire group
DC link group with other AX5000 servo drives:
Note
No DC link group permissible with devices for 1.5 A to 40 A!
Servo drives from the series AX5101 to AX5140 are excluded from the DC link group with
servo drives from the series AX5160 to AX5193 and may NOT be connected to one an-
other! The DC link group described here is permissible only for AX5160 to AX5193 servo
drives!

9.9 Leakage currents
When operating servo drives, operationally related leakage currents occur in various frequency ranges
(capacitive): In addition, it is possible for a smooth DC residual current (ohmic) to be produced after the
rectifier. These currents would prevent a residual current circuit breaker (RCCB or RCD) of the type A or AC
from tripping. In the event of a fault, therefore, it would be possible for dangerous voltages to be present on
the housing parts. For 3-phase applications the statutory regulations in different countries (please check
whether your country is affected) require the use of AC/DC-sensitive RCDs. These should have a rated
residual current of ≤ 300 mA. In order to be able to meet these requirements it is necessary to know or
calculate the expected leakage currents.
Formulas
The leakage current level depends on the fixed leakage currents, the motor cable length and the supply
voltage. The following formulas were determined empirically.
Note
Calculation basis
The values for the leakage current calculated with the equations are valid only if:
• original Beckhoff motor cables are used and
• shielding and grounding concepts are adhered to
• In addition it should be noted that the calculated leakage current value is not exact but
merely reflects the maximum expected value, with associated dispersion.
Note
Composition of the max. total leakage current
The max. total leakage current is composed of:
• a device-dependent fixed part with 50 Hz (single-phase feed) or 150 Hz (three-phase
feed)
• plus a variable part that depends on the motor cable length and clock frequency. If no
other specifications are applied, the clock frequency is around 8 kHz.

Leakage currents in a DC link
If several devices are connected via a DC link, only the fixed leakage currents for 50 Hz or 150 Hz are
present, as long as no axis is enabled. As soon as an axis is released, the complete fixed leakage currents
(50 Hz or 150 Hz) are present and additionally a fixed portion of 8 kHz with a motor cable length of 0 m. The
following diagrams illustrate the individual leakage current components:
Sample
1 x AX5000 (enabled) without DC link
ILCtotal = ILCvar + ILCfix
2 x AX5000 (not enabled) in DC link
IABtotal = IABfix_1 + IABfix_2
1 x AX5000 (enabled) + 1 x AX5000 (not enabled) in DC link
IABtotal = IABvar_1 + IABfix_1 + IABfix_2
If the AX5000_2 is also enabled the equation is as follows:
IABtotal = IABvar_1 + IABvar_2 + IABfix_1 + IABfix_2
Influence of the motor chokes
Motor chokes are used in order to protect the power semiconductors and the motors through lower voltage
edges and therefore reduced peak values of the commutation or leakage currents. However, the reduction in
voltage edges has no influence on the RMS value of the leakage currents. Since this is precisely what an
RCD invariably assesses, motor chokes have no positive influence here.

ZS4500-2006 (standard) and ZS4500-2007 (optional)
The connection type (single-conductor) in the two connectors ZS4500-2006 and ZS4500-2007 is identical.
The ZS4500-2007 is additionally equipped with LEDs. The following diagram shows the ZS4500-2006.
A sensor (F) is connected at terminal point "0" via a single-conductor connection. The 24 V supply for the
sensor is connected externally. It would also be possible to take the 24 V supply for sensor (F) directly from
terminal point "24", which would cover this option.
In this case terminal point "7" is configured as an output. The configuration is implemented on the software
side. A relay (G) is connected via a single conductor; the 0 V connection is external.
Note
Ground potential
• If sensor (F) or further initiators are supplied through a separate power supply unit, the
ground potential of the separate power supply unit must be connected with the ground
potential of terminal point "GND" of connector "X03" (24 V supply).
• The ground potential (0 V) of the relay (G) must be connected with the ground potential
of terminal point "GND" of connector "X03" (24 V supply).

The terminal points at (B) are internally bridged. The two bridges (A) have to be established externally on the
plug, in order to use the terminal points.
A sensor (C) is connected at terminal point "2" via a two-conductor connection.
An initiator (D) is connected at terminal point "4" via a three-conductor connection.
In this case terminal point "7" is configured as an output. The configuration is implemented on the software
side. At this point a relay (E) is connected via a two-conductor connection.
9.12 Feedback
Information on commutation can be found in chapter 10.12: "Commutation techniques [}200]".
Information about the limit frequencies can be found under the interface descriptions.
Note
Absolute encoder
When using an absolute encoder, it must be verified before moving the axis that the feed-
back system supplies the expected position data at the distinctive positions in the travers-
ing range - ‘START’ and ‘MID’ and ‘END’ – and that these positions are retained after the
restart (Bootstrap -> OP) of the AX5000. Overflow in the traversing range must be avoided!

Heidenhain:
The Heidenhain company supplies feedback systems with the "EnDat 2.2" interface in 2 versions. One
version is without the analog signals (sine and cosine), one version includes the analog signal "1Vss". To
date, Beckhoff supports only EnDat 2.1 with analog signal. Since the EnDat 2.2 interface supports all of the
commands of EnDat 2.1, attention only needs to be paid to the provision of the analog signal 1Vss on the
Heidenhain feedback systems with EnDat 2.2; i.e. the Heidenhain order designation "EnDat02" must be
stated.

9.13 Motors
9.13.1 Concept
Both three-phase synchronous motors and three-phase asynchronous motors can be driven with the servo
drives from the AX5000 series. The operation of asynchronous motors with the AX5000 is useful if, in the
configuration of the drive system, a channel is still freely available and also if asynchronous motors are used
that are to be operated with open-loop control. In the case of the use of asynchronous motors intended for
closed-loop operation, the AX5000 series is a good alternative regardless of the configuration of the drive
system.
9.13.2 Motor data set
A motor dataset contains the motor data and control parameters, which the AX5000 requires for operating
the motor. Beckhoff is continually expanding the pool of available motor data sets and makes the latest
motor database available automatically when the TwinCAT Drive Manager is updated.

3. Basic motor data
The basic data are subdivided into three categories: "Basic" (1); "Temperature:" (2) and "Brake" (3).
Basic (1):
Note
It is essential to observe the maximum permitted du / dt of the motor winding!
a) Type of connection: Star or delta connection. If you wire and operate the motor in a star or delta
configuration, please note that the rated motor current changes along with the rated motor voltage and that
the AX5000 can supply a maximum rated voltage of 480 V. Please refer to the motor documentation or name
plate for the permissible motor voltages and currents for star and delta connection.
b) The derating is dependent upon your application. Derating is the difference between the effective rated
channel current and the rated motor current in %. Example: rated motor current = 4 A; effective rated
channel current = 3 A -> derating = 25 %.
c) The ratio of Ip to In (overload factor) is set to 1.5 as standard and must be checked against the motor
documentation or name plate.
d) The rated current must be adjusted in accordance with the type of connection and checked against the
motor documentation or name plate.
e) The maximum motor speed is dependent upon the mechanical properties and the maximum rotary field
frequency of the AX5000. Please observe the M / f curve and the field weakening according to the motor
documentation.
f) The rated voltage must be adjusted in accordance with the type of connection and checked against the
motor documentation or name plate.
g) The nominal speed is dependent upon the number of pole pairs and the nominal frequency and must be
checked against the motor documentation or name plate.
h) The nominal frequency is set to 50 Hz as standard and must be checked against the motor documentation
or name plate.
i) The power factor (cos phi) is set to 0.8 as standard and must be checked against the motor documentation
or name plate.
Temperature (2):
k) The type of motor temperature monitoring used and the AX5000 input used must be selected.
Note
For further information on the combinations you intend to use please contact
the Beckhoff applications department.
m) The temperature at which a warning is given is set to 80 °C. This parameter is effective only for KTY
sensors.
n) The temperature at which the motor is switched off is set to 140 °C and must be checked against the
motor documentation or name plate. This parameter is effective only for KTY sensors.
Brake (3):
o) The type of motor brake used must be selected and checked against the motor documentation or name
plate.

suggested file name (2) corresponds to the motor type entered above (see "Characteristic motor data"). This
storage folder has the advantage that you can find your self-generated motor data sets at a glance; however,
they are not included in the above list above under 1. ‘Motor selection’, but are only visible if you click the
‘Load’ button at the bottom right under 1. ‘Motor selection’. The suggested name designates only the XML
file of the motor data set. For the purposes of displaying in the lists, the XML file is read and the
corresponding identifying motor data (‘Vendor’, ‘Motor group’ and ‘Motor type’) are listed as a selection.
To save your data, click on "Save" (4), which then takes you to the last menu.
If your self-generated motor data sets are to be listed directly in the above list under 1. ‘Motor selection’, click

5b. Default storage folder for the motor data sets from the Beckhoff motor database
The default storage folder for the motor data sets provided is called "MotorPool" (4). All motor data sets from
the Beckhoff motor database are saved here in the form of XML files. We recommend that you assign a
unique file name to your self-generated motor data set, so that you can identify it (5):
Customer = name of your company
Mototec = The name (Vendor) assigned by you under 2. "Identifying motor data"
3000 = The motor group assigned by you under 2. "Identifying motor data"
17K456FGH = The motor type assigned by you under 2. "Identifying motor data"
Of course, you can also assign an arbitrary file name. The assigned name designates only the XML file of
the motor data set. For the purposes of displaying in the lists, the XML file is read and the corresponding
identifying motor data (‘Vendor’, ‘Motor group’ and ‘Motor type’) are listed as a selection.
You create one XML file for each motor data set; the motors from the same motor group of a manufacturer
(Vendor) are always summarized in the XML files for Beckhoff motor data sets.
To save your data, click on "Save" (6), which then takes you to the previous menu.

i) Selection of the type of ASM connection. If you have generated the motor data set, you can only select the
type of connection entered under 3. "Basic motor data –a)". If Beckhoff has generated the motor data set,
you can choose between star connection and delta connection.
k) Selection of the ASM control mode. If you select "U/f control", only open-loop operation of the motor is
possible; the AX5000 then acts like a servo drive. If you select "i-control with feedback", closed-loop
operation of the motor is possible, but the motor must be equipped with a feedback system. Click on "OK" (1)
to complete the procedure.

Open-loop
If open-loop operation of the motor is desired, you can influence the operating behavior with the following
parameters.
Interdependence between the type of connection of the motor, the speed and the rated output
current of the AX5000
Example motor:
Asynchronous motor with rated voltage 230 V and rated current 6 A at 50 Hz for delta connection or rated
voltage 400 V, rated current 3.5 A at 50 Hz for star connection
If your application requires speeds above the nominal speed (1), this requirement can be realized without
having to use a bigger motor:
The AX5000 can provide 400 V of channel output voltage and thus operate the asynchronous motor in delta
connection at up to 87 Hz (2) without field weakening occurring, i.e. with the rated torque. You only need to
note that a rated current of 6 A is required.

Version: 2.4
Boost voltage
The operation of an asynchronous motor with a linear U/f characteristic curve results in a weakening of the
torque in the lower speed range due to the dominant resistive component. The standstill torque is zero
without a boost voltage. Furthermore, the asynchronous motor requires a certain time after the current is
applied in order to build up the magnetic field on the rotor and, hence, to generate the magnetic force or the
torque. If your application can not tolerate this delay, there is a possibility to reduce this time delay via the
so-called "boost voltage", which "premagnetises" the rotor. With "premagnetization" a magnetic field is
created in the rotor even though the rotor is not moving. Torque is hence immediately available to rotate the
rotor shaft if a target speed is specified. The interdependence between the boost voltage, speed and torque
is illustrated in the graphic below on the basis of an example motor. The influence of the boost voltage on to
the torque is clearly visible at low speeds.
Example motor:
Rated speed: 1410 rpm
Rated torque: 10.2 Nm
Breakdown torque: 28.6 Nm
Starting torque: 25.5 Nm
Power factor: 0.78
Efficiency: 0.79
The boost voltage is parameterized in the IDN-P-0-0103. Most applications will be covered by the default
setting of 10 V.
Attention
Attention: destruction of the motor
In an asynchronous motor without an external fan, the motor temperature must be moni-
tored in the lower speed range when boost voltage is used. If necessary, you can change
the boost voltage online.
Electrical installation
Servo Drives AX500096 Version: 2.4
Settings for ramping up and down
In the open-loop operation of the asynchronous motor, the values you need to adjust for the ramps depend
on the application.
The ramp-up is parameterized in the IDN S-0-0136 and the ramp-down in the IDN S-0-0137.
Closed-loop
If closed-loop operation of the asynchronous motor is desired, you must select the feedback system used in
the motor in the TCDM.
Feedback
Start the TCDM and click the entry (2) under the relevant channel (1) in the tree; the motor/feedback
configuration appears in the TCDM working area. Click on the ‘Feedback 1’ (3) field to open the ‘Feedback
selection window’. You can view all available feedback systems in the ‘Feedback selection window’.

1a. Feedback selection - resolver
Only one of the listed feedback systems can be selected. Either choose the feedback system of an existing
manufacturer or choose a standard feedback system under "Unknown" (1). If your motor is equipped with a
resolver, determine the generic parameters of the resolver and select the appropriate resolver type (2).
Typical generic parameters for the classification of resolvers are the number of poles "p" and the gear ratio
"n". Click on "OK" (3) to complete the procedure.

1c. Feedback selection - TTL encoder
You can only select one existing feedback system. Either choose the feedback system of an existing
manufacturer or choose a standard feedback system under "Unknown" (1). If your motor is equipped with a
TTL encoder, determine the parameters of the feedback system and select the appropriate TTL encoder (2).
Typical parameters for the classification of TTL encoders are the number of lines ‘s’ and the supply voltage
‘5V or 5V fixed’. The difference between the two voltage variants is the use of a sense line (5V). Click on
"OK" (3) to complete the procedure.
Note
TTL Encoder!
Wire break detection is not supported for TTL encoders.
Commutation
In asynchronous motors the rotor magnetic field is generated electrically by means of rotor windings, which
are energized by the servo drive. For this reason, neither a part-absolute nor an absolute encoder system is
required for commutation; wake+shake also does not need to be used. The magnetic field of the stator
induces a voltage in the rotor windings. This leads to a current flow in the rotor windings. This in turn
generates a magnetic field, which produces a torque.

9.15 Motors and cables for servo drives
With longer motor cables the resulting commutation currents can lead to EMC faults. Use the tables below to
check whether mains chokes or mains filters have to be used in your application. When selecting the control
cabinet ensure that there is adequate space for mains chokes and mains filters, etc.
Lay the power and signal cables in separate metal cable ducts or, if both types of cable use the same metal
cable duct, make sure there is an earthed metal dividing wall between the cables.
Note

10.1 Commissioning
10.1.1 Important information for commissioning
WARNING
Caution - Risk of injury!
Electronic equipment is not fail-safe. The machine manufacturer is responsible for ensuring
that the connected motors and the machine are brought into a safe state in the event of a
fault in the drive system.
Please be aware each time before commissioning the AX5000 that connected motors can make uncontrolled
movements, which cannot always be prevented even by the AX5000’s integrated diagnostic system, or may
permit uncontrolled movements until the diagnostic system responds. Analyze your system and take suitable
precautions to prevent damage being caused by these uncontrolled movements.
Potential causes of uncontrolled movements:
The diagnostic system of the AX5000 is equipped with complex plausibility checks, which constantly monitor
installation, operation, parameterization and operation and, if necessary, interrupt them with a diagnostic
message. The parameters listed below are monitored by default, although it is not possible to cover all
eventualities.
• Incorrect commutation results (e.g. on wake & shake), please note chapter Commutation techniques-->
Commutation error "F2A0".
• Take special care with third-party motors: When a motor or encoder is replaced or when a different
SysMan file (.TSM) is used, always execute the command "P-0-0166" without load connection and
analyze the result. If necessary, adjust the commutation offset, as described in the chapter on the
commutation process.
• Input of invalid parameters
• Measuring transducer and/or signal transducer defective or incorrectly adjusted
• Cables defective or not adequately shielded
• Incorrectly attached sensors
CAUTION
Increased attention in the case of vertical axes!
When commissioning vertical axes, the risk consideration described above is to be carried
out with particular care. An uncontrolled movement can mean the sudden falling down of a
load in this case.
10.1.2 Software requirements
Generally, two TwinCAT software modules are required for controlling the AX5000:
• TwinCAT NC PTP
• TwinCAT PLC
TwinCAT NC is a closed software module whose features the user can only influence via parameters. The
TwinCAT NC parameters can be set in the TwinCAT System Manager.
TwinCAT PLC is a program code which the user creates in the PLC Control development environment.
Advanced system characteristics
Servo Drives AX5000 107
Version: 2.4
Structure of TwinCAT NC PTP
TwinCAT NC has 2 tasks:
• NC task 1 SPP (Set PreParation task)
• NC task 1 SEC (Set ExeCution task)
The SPP task is responsible for planning the requested traversing task. The SAF task is responsible for
executing the motion command.
The traversing task leaves the PLC in the direction of the ADS router with destination NC-Task 1 SVB (NC
task 1 SPP). The router relays the telegram to this task.
The NC accepts or rejects the message. The response arrives back at the calling block in the PLC via the
same route. Instructions are issued based on blocks contained in TCMC.lib. Once the NC has accepted the
instruction, the system tries to calculate a solution taking into account the boundary conditions (max.
velocity, acceleration, deceleration, and jerk).
Advanced system characteristics
Servo Drives AX5000108 Version: 2.4
If a solution exists, a table containing the position (s) velocity (v), acceleration/deceleration (a) and jerk (j) for
the whole travel time within the sampling time of the SEC task is transferred to the SEC.
If no solution exists, the system deviates downwards based on maximum jerk, maximum acceleration, and
maximum velocity (in this order).
Actual and set values shown in the diagram are served by the 1_Enc axis and 1_Drive axis components.
Since the AX5000 is known to the system as a slave, linking can take place automatically if required. In the
event of problems the link can be checked by the user.

Adding EhterCAT master and drives
You can implement your drive in your TwinCAT project either manually or via an automatic scan. It is
advisable to scan, because this will insert the required drive devices directly into the project.
TwinCAT in ConfigMode
To start the scanning process, TwinCAT must be in ConfigMode. ConfigMode is one of several TwinCAT
states, which is displayed in the status bar of the System Manager. If the text is highlighted in blue,
ConfigMode is activated, and the scan can be started. If the text is highlighted in green or red, follow these
steps:
Click the blue gear icon in the toolbar.
You will see a query regarding the state change to be
carried out.
Confirm the state change with OK.
→
TwinCAT switches to ConfigMode, and the text highlighting
in the status bar turns blue.
TwinCAT is in ConfigMode.
Start drive scanning
If the right target system and ConfigMode are enabled, the scan can be started.
In the System Manager select I/O - Configuration → I/O
Devices.
Press the Scan in the toolbar or right-click on I/O Devices
and select Scan Devices….
In both cases, the following sequence starts:
Close the information window with OK.

TwinCAT project.
As a minimum, select the device with the supplement
(EtherCAT).
Complete the selection with OK.
Advanced system characteristics
Servo Drives AX5000 113
Version: 2.4
In the System Manager all selected devices are shown
below the "I/O Configuration" icon.
Confirm the subsequent query whether the boxes should be
scanned with Yes
If the query is answered in the negative, no boxes /
EtherCAT slaves and therefore no drives are scanned.
The message regarding a found servo drive or servo
terminal can trigger a special scan for motors. Reads the
electronic type plates of the motors and enters the data
directly in the TCDriveManager.
Confirm the query with Yes to read the electronic type
plates.
If the query is not confirmed, no name plates are read. In
this case, the motor types must be entered manually. See
Determining the motor type [}115].
Wait for the scan to complete.
The System Manager then shows the servo drives and
terminals that were found. To control the motors via the
TwinCAT project, an NC or CNC axis configuration has to be
created.
Confirm the query with Yes to create an NC axis
configuration.
Advanced system characteristics
Servo Drives AX5000114 Version: 2.4

Determining the motor type
If a motor has no electronic name plate or the offer to scan for motors was declined, the motor type has to be
entered manually in the TCDriveManager.
Opening the TCDriveManagers
• In the System Manager, under I/O configuration → I/O devices, select the EtherCAT master, to which
the AX5000 units are connected. In this example select "Device 6" for the AX5000. Here, open "Drive
9" (1).
• Open the Configuration tab (2).
→ The TCDriveManager is open.
Motor settings
In the Configuration tab, a tree structure is shown on the left, which can be used to navigate to the individual
dialog pages. To check or set the motor type, edit the motor and feedback settings (3).
• Open either Channel A or Channel B → Parameter → Motor and Feedback (3).
The motor and feedback settings appear to the right of the tree.
If the fields Motor type (4) and Feedback 1 type (5) are empty, this may have two reasons:
1. The motor does not have an electronic name plate: Determine the motor without electronic type plate
[}116]
2. The motor has an electronic name plate: Determine the motor with electronic type plate [}117]

is connected.
Make the required settings.
Confirm the selection with OK.
Selecting a motor type makes it appear in the Motor
type field (1). When the motor type is selected, the
encoder system used in this motor type also
becomes known and is shown in the field Feedback 1
type.
When the motor type is specified, a further query
appears, as to whether the NC or CNC parameters
relating to this axis should also be set.
If you confirm this message with OK, you will be
directed to the corresponding settings. See Create NC

Specifying the scaling factor
The scaling factor is an application-related parameter, which is required for converting the position
representations between the NC and the AX5000. The NC is usually parameterized in the application unit
(e.g. degree). The AX5000 operates with a position representation of 2x increments per revolution (with x =
[20...31]). If, for example, a motor revolution corresponds to an application revolution (360 degrees), and x =
20 was selected, the resulting scaling factor is 360 degrees / 220.
.
In the System Manager tree, open I/O –Configuration
→ I/O Devices → Device 6 → Drive 9 (1).
Open the TCDriveManager via the Configuration tab
(2).
In the TCDriveManager tree select Channel B →
Parameter → Scalings and NC Parameters (3).
A table with different NC parameters and the
corresponding values (4) can be found to the right of
the TCDriveManager tree. Since the initial parameter
values are default values that were not explicitly
saved by the user, they are regarded as invalid and
therefore shown in red font. The individual parameter
values depend on the scaling factor, so that all
parameter values can be adjusted by modifying the
scaling factor.
Adjust the scaling factor via the field Feed constant
(5).
Select the unit (6).
Confirm the change with Save (7).
Acknowledge the information window with OK.
By confirming the change, the parameter values and

Open the Online tab (6).
Setting the drive enables
To operate the motors manually, manual drive control
must be enabled. The control is activated when
Enabling Controller (7) is active. In addition, the drive
requires Enabling Feed Fw** (7) activated for forward
travel, and Enabling Feed Bw (7) for reverse travel.
Use the Set button (8) to change the settings.
Use the All (10) button to set all settings and the
override (11) to 100%,
or all settings can be specified manually:
Tick the individual options (9) to activate them.
Enter the Override value (11).
The override (11) scaled the set velocity of the NC
motion command. The Override value can be
between 0% and 100%.
In the function view, the activated options are
indicated by ticks (12). In addition, the Status (log.)
(13) has changed with the activation, and the override
has been entered. The drive is ready for operation
and can be controlled with the manual mode menu.
*If this flag is set, the system tries to activate the drive control (of the AX5000) and to set the drive to a state
in which it follows the set value specifications of the NC. The "Ready" flag is set if the drive acknowledges
this request as successful.
**These so-called direction enables make it possible for the NC to accept motion commands in the
respective direction. The drive does not see these two flags.

Typical error messages
If you are in the manual mode menu and the position
value (2) is greyed out, this has the following reason:
A greyed out shown actual position for EtherCAT
drives indicates a "WC state error". In this case, the
WC state flag generated by the EtherCAT master is
"true", which means that the NC does not receive
valid position data from the drive.
The corresponding EtherCAT drive is probably not in
EtherCAT state SafeOp or Op. Further analysis is
required to ascertain why the drive is not in this state.
To investigate further, open the TCDriveManager via
Configuration (3). In the status bar, another error
code is shown at Diag Code (4). Check the drive
state (5). Select Diagnostics (6) from the tree
structure, in order to obtain further information about
the error. A list (7) on the right shows the whole error
history. Update the list via the button with the two
green arrows (8). Once the cause is identified and
corrected, reset the axis via the R button (9).
After a short time, the error indication will disappear
from the status line for the axis (10), and the drive will
be in OP state (operational) (11). Update the list of
error messages once more (8). It should contain no
more error messages (12).
In the manual mode menu for the axis, the position
value (13) is shown in black again.
Press the F8 button to acknowledge the NC error (14)

Wait until the scan is complete.
The Solution Explorer then shows the servo
drives and terminals that were found.
To control the motors via the
TwinCAT project, an NC or CNC
axis configuration has to be
created. Confirm the query with
Yes to create an NC axis
configuration. As a result of the
automatic axis configuration
creation, an axis is added for each
motor that was found and linked
accordingly.

10.1.4 Linear motors
10.1.4.1 Commissioning of linear motor axes
Beckhoff Automation GmbH & Co. KG does not sell complete linear motor units. Magnetic plates and coil
parts are offered for sale. The machine manufacturer selects a linear measuring system to suit the
application. The assembly takes place at the machine manufacturer’s premises. This leads to various
selection options, whose results usually cannot be determined until commissioning. For example, the
direction in which the measuring system counts may not be known.
An incremental measuring system is often used with linear motors. This necessitates the use and
configuration of "Wake & Shake".
Requirements for commissioning
XML motor description
The XML description matching the motor is required for the commissioning of a linear motor on the AX5000
servo drive. The associated XML files for Beckhoff linear motors are contained in the TwinCAT setup
(AX5000 Download Package).
Note
XML files for third-party motors!
In the case of third-party motors the required XML descriptions can be generated with the
help of the "Tc Motor Data File Generator".
XML measuring system description
If a measuring system is used, it must also be present in the form of an XML description. Without this XML
description the measuring system does not appear in the TC Drive Manager selection list. A missing XML
description can be generated exclusively by Beckhoff Automation GmbH & Co. KG.
If an incremental (non-absolute) measuring system with sine/cosine or TTL signals is used, a corresponding
system can be chosen as "Unknown" from the list shown below.
Advanced system characteristics
Servo Drives AX5000 149
Version: 2.4
An overview of feedback systems already used can also be found in the AX5000 system manual. The picture
detail below shows a selection of possible feedback systems that could come into question as a measuring
system.
Commissioning
Motor and feedback selection
The motor should be selected first, then the measuring system. This order ensures that the pole pair
distance of the linear motor is automatically taken into account in the feedback settings of the parameter.
In the case of linear encoders with TTL signals, a distinction must be made between the signal period and
the resolution. The manufacturers specify the resolution when evaluating all edges ("after quadrupling"). For
the AX5000 the signal period must be specified. A measuring system whose resolution is specified by the
manufacturer as 1 µm, for example, has a signal period of 4 µm and must be selected accordingly (picture
below):
Advanced system characteristics
Servo Drives AX5000150 Version: 2.4
Motors with a pole pair distance that is not an integer represent a special case!
It is necessary to specify the "Signal periods per rotation" in parameter P-0-0150.
Sample:
With a pole pair distance of 28.1 mm and a sine period length of the linear encoder of 1 mm, a value of 28.1
would be correct. However, only integer values can be entered there. The Tc Drive Manager therefore enters
the value 28 in P-0-0150 (picture below):
The feedback gear unit is now automatically activated in order to correct the error described above (picture
below).
Advanced system characteristics
Servo Drives AX5000 151
Version: 2.4
Scaling factor
The pole pair distance of the linear motor in millimeters is to be entered in the field "Feed constant"(picture
below). After entering the correct “Feed constant”, all positions are specified in mm, all speeds in mm/s. A
non-integer input is possible at this point. 28.1 (decimal point!) is the correct value in the above example.
The values are confirmed in the NC with "Set NC Parameters". They are only valid when the configuration is
activated.
Checking the linear encoder
Once the motor and feedback have been selected and the scaling factor has been entered, the configuration
must be activated. Subsequently the measuring system must be checked. The AX5000 must not report any
feedback error when doing this. Please observe the notes in the section “Troubleshooting [}160]”.
Observe the position in the NC. Push the motor by hand during this procedure. The distance by which the
motor is pushed must be correctly displayed in the NC.
If a measuring system is used that can read out absolute and incremental signals, then the absolute and
incremental tracks must have the same counting direction. Therefore, the two tracks have to be compared
beforehand. The absolute position is read by the AX5000 only when switching on/restarting. Then it switches
over and evaluates only the incremental information (sincos or TTL signals).
Important: Up to this step the counting direction should not be inverted via a parameter at any point!
Advanced system characteristics
Servo Drives AX5000152 Version: 2.4
Now push the motor by hand. While doing this, observe the direction in which the position increases. Switch
the AX5000 to the "Init" state and then to the "Op" state (picture below). Using this procedure the absolute
position is read out again.
Note the absolute position read out. Now push the motor in the direction of the increasing position. Then
switch the AX5000 once again to the "Init" state and then to the "Op" state (picture below). If the absolute
position displayed after this procedure is larger than the one noted beforehand, both tracks are counting in
the same direction.
If a smaller position is displayed, the counting direction for the incremental encoder signals must be
reversed. This should be done by hardware means, for example by swapping the SIN+ and REFSIN signals
in the feedback connector.
Now repeat the test!
Note
Counting direction doesn’t correspond to the application!
If the counting direction of the linear encoder doesn’t correspond to the desired counting di-
rection in the application, this can be ignored at this point. The necessary settings can be
made at the end of the commissioning. The requirement for this is that the motor drives
without errors.
Advanced system characteristics
Servo Drives AX5000 153
Version: 2.4
Checking the motor phases and the encoder counting direction
If the absolute and incremental positions of the linear encoder have the same counting direction (or if there is
only an incremental position), the phase sequence of the motor can be compared with the encoder counting
direction. This can be checked using the command P-0-0166 "Motor and feedback connection
check" (picture below).
If the command P-0-0166 has been selected for checking the motor and feedback connection (picture
above), the input mask of parameter P-0-0167 appears. The parameters in the upper area should not initially
be changed.
The main voltage (e.g. 400 V) must be switched on in order to execute the command. The AX5000 must be
ready but not enabled. The "Diag Code" is 0x0000D012.
Attention
The execution of this command causes a movement of the motor!
Before confirming the following message with "Yes", make sure that the motor can move
freely and cannot cause any damage.
Advanced system characteristics
Servo Drives AX5000154 Version: 2.4
The following message appears during the first execution:
The linear motor first jerks and then makes a further movement a few seconds later.
If the command was executed successfully, the message "Succeeded to start the command" appears.
Values are hereby entered in parameter P-0-0167 "Results" (picture below).
It is important that the result "1:Yes" appears in the setting "Equal Directions" (picture above → red circle). If
"0:No" should appear there, two phases of the motor connection (AX5000 X13/X23) need to be swapped,
e.g. U and V.
The command can also be executed repeatedly.

Determination of the commutation offset
If the order of the motor phases matches the counting direction of the measuring system, the commutation
offset can be determined. In the case of absolute measuring systems, the commutation offset is only
determined once. The value is saved. In the case of incremental measuring systems, the "Wake & Shake"
must be configured. The commutation search then takes place automatically after each restart, when
enabling the servo drive for the first time.
With incremental measuring systems
Attention
Use of incremental measuring systems for vertical axes!
Beckhoff Automation GmbH & Co. KG urgently advises you not to use incremental measur-
ing systems with vertical axes. A reliable commutation search is not possible with this com-
bination!
Parameter P-0-0160 executes the commutation search. The behavior is configured with parameter
P-0-0165. The "Static current vector" method can be used for test drives. It is preferable to use "Wake &
Shake" in operation. It causes less movement of the axis. Both methods are executed using the command
"Start" (picture below → red circle). All settings should initially remain unchanged. The routine must be
completed without error. The message "Succeeded to start the command" (picture below → red circle)
should appear.
After successful execution of the command, the axis can be driven for test purposes; see below. Following a
successful test the entries "Command Mode" and "Activation" in parameter P-0-0165 should be changed to
"Wake & Shake" and "1:On enable request" respectively.
In most cases the default settings for "Wake & Shake" can be left unchanged. In many applications it is
useful to set the parameter "Commutation pos control: Kp" to 0. Details for this can be found under the
keyword "Electronic Commutation" in the Beckhoff Information System.
Note
Further information can be found in the parameters:
P-0-0160 and P-0-0165.
Advanced system characteristics
Servo Drives AX5000156 Version: 2.4
With absolute measuring systems
The AL2200-MES-Feedback indicates only the absolute position in relation to a pole pair. Homing is
necessary each time after switching on. The commutation offset only needs to be determined once and
saved. The commutation offset is determined in the same way as with other absolute measuring systems.
For that reason the AL2200-MES-Feedback is not described separately here.
Set the values for "Commutation Mode" and "Adjustable Commutation Offset (mechanical)" in parameter
P-0-0150 (see picture below).
The configuration must be activated to confirm the settings. Command P-0-0166 is used to set the electrical
commutation offset.
CAUTION
The execution of this command causes a movement of the motor!
Wait for the message "Succeeded to start the command"!
Advanced system characteristics
Servo Drives AX5000 157
Version: 2.4
"Yes" must appear as result under "Equal Directions".
Read the value for "Commutation position difference". Subtract this value from the value in P-0-0057
"Electrical commutation offset". The result, if positive, is the new value for P-0-0057. Add 360° to the result if
it is negative.
Sample:
90° - 121.78° = -31.78°
-31.78° + 360° = 328.22°
The result is the new value for P-0-0057 "Electrical commutation offset". Enter the value in SetValue and
confirm with <Enter>. Confirm the message that then appears with Yes (picture below).
The new value becomes active immediately upon pressing the download button (red arrow → picture below).
Advanced system characteristics
Servo Drives AX5000158 Version: 2.4
The value is displayed in the setting "ActValue" after the download is complete. Execute command P-0-0166
again!
The value for "Commutation position difference" should now lie within the range:
355 ... 360 = 0 ... 5.
If this value is displayed you have successfully completed the commutation search!
The offset value has already been adopted into the startup list with the download button.
If the value lies outside the range, P-0-0057 can be corrected again using the method described. If no useful
value is found, the more detailed check should be performed with the help of command P-0-0166. In this
case, please observe the section: "Checking the motor phases and the encoder counting direction [}153]".

Further information can be found in the parameters:
P-0-0057, P-0-0150 and P-0-0166.

Version: 2.4
Moving the axis for test purposes
Use the jogging buttons of the NC to move the axis at a slow speed. Do not execute the “Reversing
function”. Allow the motor to move by at least one pole pair in order to ensure that the commutation works
properly!
Note
Lag error if the velocity controller is not optimized!
It is possible for large lag errors to occur as long as the velocity controller has not been op-
timized!
• Test the travel movement at slow speeds and low acceleration.
• Allow a large lag error where possible.
If the axis travels only a few millimeters and then stops while drawing a high current, carry out the
commutation check [}153] using command P-0-0166.
Determination of the control loop parameters
The determination of the control loop parameters of a linear motor axis is done in the same way as with a
standard axis. For that reason only an abridged procedure is described here.
In most cases the preset proportional gain in the velocity/speed controller is much too small. This is set in
relation to the motor mass. In particular in the case of linear motors, the external mass can be large in
comparison with the motor mass. This case requires a significant enlargement of Kp.
Advanced system characteristics
Servo Drives AX5000160 Version: 2.4
Abridged procedure:
1. Set Tn to ≥ 30ms (to reduce oscillation of the axis).
2. Start a reversing function at a moderate speed.
3. While the axis is moving, increase Kp in the "Controller Overview" window in steps of, for example,
20% up to the oscillation limit. (It is possible to check by axis noise).
4. Reduce Kp by about 20% until the oscillation reliably stops.
5. Also check that the axis doesn’t oscillate when it is at a standstill.
6. Reduce Tn
A value of between 5 ms and 10 ms is useful if the load is coupled normally.
The value must be increased if oscillations occur.
7. Kv = 1 in the position controller is usually okay. Reduce Kv (for example to 0.5) if the axis overshoots
the position after optimizing the velocity controller.
Kv can also be increased if an overly large lag error occurs.
Troubleshooting
Feedback error
It is important to read all messages in order to identify the causes of errors. In the case of feedback errors in
particular, the AX5000 normally outputs several error messages at once.
Errors in connection with the feedback power supply
Make sure when selecting a feedback system with the designation “Unknown” that the power supply is set
correctly (picture below)!
Advanced system characteristics
Servo Drives AX5000 161
Version: 2.4
If the setting is "5V", the AX5000 expects a sense line to be connected. The setting "5V fixed" must be
deselected if the encoder employed does not have a sense connection.
The selection leads to different settings in the "Power Settings" in the feedback parameter P-0-0150 (picture
below).
An incorrect selection leads to AX5000 error messages (see section “Error codes”). [}161]
Error during activation (enable) of the AX5000
If the shield of the motor cable and/or feedback cable is not connected over a large area with the housing of
the AX5000, this leads to a feedback error in the current feed to the linear motor. The position is then
correctly displayed only when pushing the motor by hand.
The shield of the motor cable is normally connected with a clip to the metal bracket of the motor connector.
The screws of the motor connector (X13/X23) must be screwed to the housing of the AX5000 and fastened
with a tightening torque of 0.6 Nm.

tial errors that are not described in this section!
Advanced system characteristics
Servo Drives AX5000162 Version: 2.4
Error F4A5 "SoE Communication Parameter Error"
The parameter that caused error F4A5 is output in parameter S-0-0021 (picture below). This can be read in
the Diagnostics window.
In this case F152 and FA01 are consequential errors of F4A5. The cause of the error is an incorrect setting
in parameter P-0-0150.
A value > 0 must be entered for "Signal periods per rotation" (picture above). This takes place automatically
if, during the configuration, the motor is selected first and then the feedback.
The correct value is the pole pair distance / ("Length per signal period")
Sample:
Signal periods per rotation = 24mm / 1000000nm = 24
Advanced system characteristics
Servo Drives AX5000 163
Version: 2.4
The error message F4A5 can also occur with a reference to parameter S-0-0113 "Maximum motor speed":
In this case the additionally occurring error message FD15 allows a conclusion to be drawn about the cause:
the selected measuring system and the maximum velocity configured in S-0-0113 result in a too high input
frequency at the encoder input (X11/X21).
Sample:
Measuring system with 20 µm signal period. Maximum travel speed of the motor = 12 m/s.
12 m/s : 20µm = 1000000 1/s = 1 MHz
The max. permissible input frequency for sine/cosine signals at X11/X21 is 250 kHz.
Remedy: Reduce the value of S-0-0113. The maximum possible speed of the motor is required only in very
few applications.
Note: The value of the max. speed is shown in the parameter list in rpm. In the case of linear motors 1 rpm is
one pole pair distance per minute.
Conversion of the displayed value for a motor with a pole pair distance of 24 mm:
30000rpm * 0.024m / 60 = 12 m/s
Note
Further information can be found in the parameters:
S-0-0021 and P-0-0150.

Servo Drives AX5000164 Version: 2.4
Error F107 "Status of the axis: current controller not ready"
If this error appears, the entry "Commutation Mode" in parameter P-0-0150 must be changed from "No
commutation" to "2:Commutation Offset 0 deg" or "3:Adjustable mechanical Offset". Refer also to section
"Determination of the commutation offset".
Attention
Nature and source of the danger
The setting "0: No commutation position" is intended to prevent an axis being inadvertently
activated and then moving in an unforeseeable manner or "running away". If not already
done, it is essential after the change to determine a valid commutation offset before the
axis is activated (enabled).
Advanced system characteristics
Servo Drives AX5000 165
Version: 2.4
Checking the motor connection and feedback
The motor can execute a defined movement independently of the feedback on the basis of command
P-0-0166. If the movement is observed (e.g. with the software oscilloscope), conclusions can be drawn
about the feedback settings.
Enter a value of 360 degrees in parameter P-0-0167 in the setting “Moving distance”. On execution of
P-0-0166 the motor is then moved by one electrical revolution. In the case of linear motors this corresponds
to one pole pair distance. Since the motor executes an undefined movement before that, it is a good idea to
record the complete movement with the software oscilloscope.
The following signals should be recorded:
• Torque Feedback (S-0-0084)
• Position feedback value 1 (S-0-0051)
• ActPos (from the NC)
Advanced system characteristics
Servo Drives AX5000166 Version: 2.4
If the motor doesn’t move by the expected pole pair distance, check the value entered in parameter
P-0-0125 (Pole pair distance).
The jerky movement at the beginning (picture above → red arrow) is not included in the observation. The
motor aligns itself via the poles.
From the current curve it can be seen that the value initially ramps up and is then kept constant for a while.
During that time the direction is electrically turned once. The value set in parameter S-0-0051 should
increase by approx. 220 (1048576) increments. The NC position (ActPos) should increase by the value of a
pole pair distance. In the example the values are sufficiently precise with 1020612 and 23.357.
If the increase of S-0-0051 differs considerably from 220, the resolution of the linear encoder has not been
entered correctly.
If S-0-0051 proceeds correctly but ActPos displays a wrong difference, the scaling factor has been set
incorrectly.
The connection of the motor phases must be checked if the movement does not proceed evenly, but only a
jump takes place, for example.

10.1.5 Third-party motors
10.1.5.1 Commutation offset for third-party motors
10.1.5.1.1 Preliminary remark
This section provides information on checking a direction of rotation and determining the commutation offset
for third-party motors.
Please observe the following notes:
A commutation offset can only be determined and stored for motors with resolver, absolute encoder (single-
or multi-turn) or the part-absolute MES.
For incremental encoders (sine/cosine or TTL signals) the “Wake&Shake” routine must be configured. This is
necessary, since in this case the commutation offset is not constant. The “Wake&Shake” routine
redetermines the commutation offset after each start.
Note
Do not use the electronic name plate!
If a motor with an EnDat or BISS encoder is used, we advise against not using an elec-
tronic name plate.
Attention
Inversion of the count direction
All direction settings must have their default values. Do not invert a count direction before
the correct commutation angle was determined!
The offset to be determined can be a mechanical offset relative to the rotor position or an electrical offset
relative to the electrical rotation. Both procedures are explained below.
Note
Further information can be obtained in the parameters:
P-0-0057, P-0-0058, P-0-0150, P-0-0160, P-0-0166, P-0-0167
Advanced system characteristics
Servo Drives AX5000168 Version: 2.4
10.1.5.1.2 Checking the direction of rotation
Please note that for proper operation the count
direction of the feedback system must match the
sequence of the motor phases.
Turn the motor shaft clockwise, viewed from the A-
side. The parameter “Position feedback 1 value” (see
lower image) should be positive. If this is not the
case, the sine and cosine signals at the motor should
be swapped.
If the motor has a holding brake, it can be released in
the TCDriveManager under “Service functions/
Manual operation” (see lower image).
Now use the command P-0-0166 to check the
counting direction of the feedback system and
whether it matches the connection of the motor
phases.
CAUTION
Motor movement!
When you check the counting direction of the motor with the command P-0-0166, the motor
will move. Therefore, please keep a safe distance from the motor with all body parts before
you start the command P-0-0166!
The AX5000 must be set inactive without error (diag
code = 0x0000D012).
After selecting the command P-0-0166 press “Start”.
Confirm the selection (Do you really want to
continue?) with “Yes”.
The command P-0-0166 was successfully completed
when the message “Succeeded to start the
command” appears in the context menu.
The verification result can now be read in parameter
P-0-0167. If the “Equal Directions” selection area
shows 0: No, change the order of the motor phases
(The direction of rotation of the feedback system was
already checked and possibly corrected in the
previous step).
Note
Please do not use a TwinCAT setting to change the motor phases at the mo-
tor connection.
Swap motor phases U and V, for example, at the motor connector plug (X13/X23).
If the “Equal Directions” selection area now shows 1:Yes, the commutation offset can be determined based
on one of the following methods.
Advanced system characteristics
Servo Drives AX5000 169
Version: 2.4
10.1.5.1.3 Determining the electrical commutation offset
Execute the command P-0-0166 (see section
“Checking the direction of rotation”). To determine the
commutation offset we need the current value from
parameter P-0-0057 and the current value from
parameter P-0-0167:
Read the value for “Commutation position difference”.
Subtract this value from the value in P-0-0057
“Electrical commutation offset”. If the result is
positive, this is the new value for P-0-0057. If the
result is negative, add 360°.
Sample:
90° - 178.57° = -88.57°
-88.57° + 360° = 271° (fractions can be neglected.)
The result is the new value for P-0-0057 “Electrical
commutation offset”. Enter the value at SetValue and
confirm with <Enter>. Confirm the message that is
displayed with <Yes>.
Pressing the download button (red circle) activates
the new value immediately.
The value is displayed in the setting “ActValue” after
the download is complete. Execute command
P-0-0166 again!
The value for “Commutation position difference”
should now lie within the range: 355 … 360 = 0 … 5.
355 … 360 = 0 … 5 liegen.
If this value is displayed you have successfully
completed the commutation search! The offset value
has already been adopted into the startup list with the
download button.
To use the commutation angle, the “Commutation
mode” must be changed in parameter P-0-0150:
Change the entry “Commutation mode” to
“3:Adjustable offset”. Then reactivate the TwinCAT
configuration.
After changing the “commutation mode” once, this
method has the advantage (compared with the
mechanical offset) that the offset (P-0-0057) can be
changed at any time without having to restart the
system.

10.1.5.1.4 Determining the mechanical commutation offset
Abridged procedure:
Note
Adjustable commutation mechanical value!
Before determining the mechanical commutation offset, check whether the value “Ad-
justable commutation mechanical” in P-0-0-0150 is set to 0. If this is not the case, set the
value to 0 and activate the TwinCAT configuration. Then perform the steps described be-
low.
1.) Run command P-0-0166.
2.) Press the "Download" and "Start" buttons. Wait until the
"Suceeded to start the command" appears.
3.) You get a new value in parameter P-0-0058 "Mechanical com-
mutation offset". Remember this value.
4.) Open the "Startup list". Open the parameter structure P-0-0150.
Open "Parameter Channel".
5.) Set parameter P-0-0150 "Feedback 1 Type" in "Commutation
mode": 3 Adjustable offset.
6.) Change the value in P-0-0150 "Feedback 1 Type" in the "Ad-
justable commutation offset (mechanical)" to the value which you
have previously read in parameter P-0-0058.
Confirm with OK and activate the configuration in the TwinCAT
System Manager.
7.) Change to the "Drive Commands" tab and execute command
P-0-0166 "Motor and feedback connection check".
8.) Leave the default values and confirm with Start. If the message
"Suceeded to start the command" appears, open the parameter
structure of the P-0-0167 "Results".
“Equal direction" must be "Yes" and "Command position differ-
ence" must be between 355 ° and 360 "(0 ° ... 5 °).
CAUTION
Motor movement!
If you execute the command P-0-0166, the motor performs a movement. Therefore, please
keep a safe distance from the motor with all body parts before you start the command
P-0-0166!

10.1.5.1.5 Configuration of the Wake&Shake routine
A configuration requirement is that the count direction
of the feedback system matches the sequence of the
motor phases.
Details of the process for finding the commutation
with “Wake&Shake” can be found in the Beckhoff
Information System under the keyword: "Electronic
commutation".
This section only contains a brief overview.
The command P-0-0160 executes the routine. The
type of execution can be set in parameter P-0-0165.
For “Command mode” you can select between: Static current vector and Wake and Shake.
• 0:
• 1:
auswählen.
The “Static current vector” procedure results in a larger motor movement. It can be used for testing.
The “Wake and Shake” procedure minimizes the axis movement. This procedure is the one that tends to be
used in practice.
Both procedures determine a commutation offset, although this is not shown in parameter P-0-0058. This is
due to the fact that a new value has to be determined at each restart. This value depends on the axis
position. The numerical value is therefore meaningless for the user.
The result can then be checked with the command P-0-0166. Both procedures should initially be performed
with the default values.
The setting “Activation 1: On enable request” has the
effect that the AX5000 automatically executes a
commutation search with the first enable after a
restart.
With "Wake and Shake" it often makes sense to set
"Commutation pos control: Kp 0", in order to avoid
execution errors.
10.1.6 Homing
10.1.6.1 Homing
Homing refers to an axis initialization run during which the correct actual position is determined by means of
a reference signal. This procedure is referred to as homing, referencing or calibration. A switch that is
triggered at a known, unique position along the travel path serves as reference signal. Further signals such
as the encoder zero track can be analyzed in order to increase the precision.
In general a distinction is made between drive-controlled homing and NC-controlled homing. Drive-controlled
homing is carried out automatically by a suitable drive without input from the control system and is not
discussed in detail in this documentation. NC-controlled homing is fully controlled by the control system and
supports a wide range of drive types. The different NC-controlled homing mechanisms are described below.

Position reference systems and encoder systems
A distinction is made between different position reference systems (measurement systems), depending on
which position measuring system is used. An absolute measurement system provides an absolute position
(directly after switching on) that is unique over the whole travel path. Such a measurement system is
calibrated once and set via a persistently stored position offset. In this case homing is not required even after
a system restart. In contrast, relative measurement systems provide a non-unambiguous position value (after
switching on) that must be calibrated through homing. Relative measurement systems are subdivided further
into purely relative systems (incremental encoders) and part-absolute systems, which only provide a unique
position during a motor or encoder revolution.

General description of a homing procedure
Figure A shows a schematic diagram of a homing procedure with individual velocity profile phases.
1. When the machine is switched on the axis is in a random position (1).
2. Homing is initiated, and the axis travels towards the reference cam.
3. Once the reference cam is detected, the axis stops and reverses.
4. The axis moves away from the reference cam and detects the falling edge of the reference cam sig-
nal.
5. The axis continues and searches for a sync pulse or another distinctive event, depending on the refer-
ence mode setting. This step may be omitted where appropriate.
6. The occasion is detected and the specified reference position is set.
7. The axis stops and thus stands slightly away from the reference position. The reference position was
set a short while before with maximum accuracy.
Figures B and C show the position and velocity profile during homing.

Servo Drives AX5000174 Version: 2.4
Referencing modes
The NC system supports different referencing modes, depending on the encoder system type.
•Homing based on reference cam (Plc Cam)
The simplest axis referencing mode uses a reference cam that generates a digital signal at a defined
position along the travel path. During homing the NC determines the signal edge and allocates a
configurable reference position to this position. Referencing based on a reference cam is always
possible, irrespective of the encoder type, and is a prerequisite for other, more precise modes.
•Software Sync
Software Sync mode enhances the homing precision by additionally detecting the encoder count
overflow after an encoder or motor revolution, after the reference cam signal has been detected. This
mode requires a part-absolute encoder (e.g. resolver) with constant overflow interval relative to the
reference cam. Overflow detection is parameterized via the Reference Mask parameter (see System
Manager section).
•Hardware Sync
Some encoder systems provide a sync pulse per revolution (zero track) in addition to the count. The
homing precision can be enhanced by selecting this mode, if the encoder evaluation logic is able to
pick up the sync pulse. The precision is comparable with Software Sync. Hardware Sync mode may
require parameterization or special wiring of the drive or encoder system.
•Hardware Latch
Hardware Latch reference mode (Hardware Latch Pos or Hardware Latch Neg, depending on edge)
requires an external digital latch signal for storing the encoder position in the evaluation unit of the
encoder system. The encoder system must support such a latch function and may have to be
configured first in order to be able to utilize this function.

Parameterization in the System Manager
Reference System : The encoder parameters Reference System determines whether the encoder system
used is incremental or absolute. In an absolute encoder system the encoder value is taken from the control
system without modification.
Not all NC encoders support this optional parameter, i.e. only those types that offer a choice between
absolute and incremental encoder reference system (measurement system) support it (e.g. SERCOS,
KL5001, M3000, ProfiDrive, Universal). This choice determines whether the actual encoder position is
interpreted and evaluated as an absolute or incremental position, based on an absolute or incremental
reference system (measurement system).
In an absolute reference system no further processing takes place with regard to encoder counter value
overflow or underflow. It is assumed that the counter value is unique within the axis traversing range and no
encoder counter value overflow or underflow occurs. Otherwise there would be a discontinuity in the actual
position, resulting in a position following error. Axis referencing via MC_Home is not possible. Instead, the
actual position is calibrated once via the parameter Position Bias (zero offset / position offset).
In an incremental reference system axis referencing via MC-Home is generally required. In addition the NC
automatically detects and accounts for encoder counter value overflow or underflow events, so that
continuous axis operation is possible over many months ("infinite range").
Encoder Mask (maximamum value): The encoder mask determines the bit width for the incremental
encoder position. The encoder mask is used for detecting and counting in range overflow events.
Scaling Factor: The scaling factor is multiplied by the incremental encoder position, including all overflows.
From this an absolute axis position can be calculated with the parameterized physical unit.
Position Bias (zero offset): Position offset; moves the axis coordinate system relative to the encoder
coordinate system. This value is mainly used in absolute encoder systems. In relative systems an offset is
usually not required, since the system moves to a parameterized reference position after homing.
Advanced system characteristics
Servo Drives AX5000176 Version: 2.4
Invert Encoder Counting Direction: The encoder count direction can be inverted if it does not match the
required logical count and travel direction.
Reference Mode : Referencing mode as described above (Plc CAM, Hardware Sync, Hardware Latch Pos,
Hardware Latch Neg, Software Sync). The default mode corresponds to Plc CAM mode.
The Reference Mode parameter is used to specify the type of reference event (physical or logical event) for
the referencing process. Depending on the parameterized reference mode, during the referencing procedure
either the hardware property of the drive or encoder (e.g. hardware latch) is used, or the reference event is
exclusively detected within the control, i.e. without further hardware reference.
Reference Mask: The reference mask parameterizes overflow detection for Software Sync reference mode.
It is less or equal the encoder mask and defines an encoder value range, which is part-absolute. Examples
include the bit width of a motor revolution or the bit width of a sine period in a sine/cosine encoder. Software
Sync therefore always detects the same overflow position in a part-absolute encoder system.
Calibration Value: Reference position to which the axis position is set after homing.
Invert Direction for Calibration Cam Search: The parameter inverts the axis travel direction for searching
the referencing cam during homing. The standard direction is negative, i.e. towards the axis coordinate
system origin.
Invert Direction for Sync Impuls Search: The parameter inverts the axis travel direction for searching the
sync pulse during homing.

Referencing of coupled axes
TwinCAT enables axis coupling during referencing. The coupled axes do not necessarily have to be
referenced. Axis coupling enables referencing of gantry axes, for example, provided the system can ensure
that the two axes are suitably oriented relative to each another before homing. In this case the procedure is
as follows:
• Ensure that both axes can be moved in coupled mode. (Position comparison is not possible at this
stage, because none of the axes is referenced.)
• Couple axis 2 with axis 1.
• Start homing for axis 1. Slave axis 2 will travel with axis 2.
• Decouple the axes after the homing procedure.
• Couple axis 1 with axis 2.
• Start homing for axis 2. Slave axis 1 will travel with axis 2.
• Decouple the axes after the second homing procedure.
• Move both axes to a set position for alignment. The travel path for both axes should be minimal and
may correspond to the mean value from both positions, for example.
• Couple the axes. The coupled system is now referenced.
Programming a homing procedure in the PLC
MC_Home
The MC_Home function block is used to initiate homing from the PLC. The reference mode and further
parameters are configured in the System Manager as described above. Only the reference cam signal
(bCalibrationCam) is fed into the block.
Drive types and I/O interface
Homing is largely independent of the drive types used. In some cases the drive has to be parameterized,
particularly if a drive latch function is used. The following chapter describes the version with the AX5000.

10.1.6.2 Special characteristics in hardware end positions
If a SERCOS or SoE drive (e.g. AX50xx) is in a hardware end position (positive or negative), the drive blocks
further traversing commands in end position direction and beyond the end position (see also bit 3, drive
follows command value, in the SERCOS status word), and is therefore no longer operational from a control
system perspective. This means that, without special measures, the axis can often no longer be moved from
the end position into the valid traversing range via TwinCAT or the control system. This situation is
particularly likely to occur with drives in the velocity interface, because in this case the position control leads
to frequent changes in direction in the drive velocity output.
In order to rectify this special situation, a control bit in the PlcToNc axis interface (see bit 8 called
AcceptBlockedDriveSignal in nDeCtrlDWord) can be used to force TwinCAT to accept the AX50xx axis as
operational and therefore enable a move from the end position into the valid traversing range.
In the past, in many cases the only alternative was to mechanically move the axis away from the end
position.

Homing with latch function
During homing a trigger event is expected and a position value is latched, depending on the referencing
mode (hardware latch). Parameterization is required in order to be able to use the drive latch function (see

10.1.7 Error messages during commissioning
The greatest likelihood of error messages occurs during the commissioning process. Incorrectly assembled
cables, missing shield connection, wrongly parameterized motors / feedback systems, mechanical problems
and many other issues are detected at this stage. The drive can often not be started or stops after a short
time with a diagnostic message.
Note
Documentation of all error messages
If an error message occurs, first of all please refer to the error message information in the
documentation "AX5000_DiagMessages". You will usually find suggestions for solutions
there which can be implemented relatively easily.
10.1.7.1 FA49, Feedback process channel error (1Vss)
When this diagnostic message appears it may indicate an error in the analog signal for the feedback system
(1Vss). The AX5000 monitors the output signals from the sin/cos 1Vss feedback system and switches off the
drive when the signal lies outside the tolerance range between 0.53 Vss and 1.34 Vss. The feedback
systems are specified in such a way that they only supply exact values within the stated tolerance range.
Beyond this the values may be usable but are not necessarily so.
Voltage analysis
With an external oscilloscope
The values from the feedback system can be determined with the aid of an external oscilloscope (scope).
You can connect an external scope between the feedback connector and the AX5000 and determine the
sine and cosine voltages.

Parameterization of the IDNs P-0-0150 / P-0-0180
Note
Feedback system 1 or 2
The diagnostic message FA49 applies to both feedback systems 1 and 2. You can find out
which feedback system is currently affected by pointing the mouse cursor at the diagnostic
message in the TCDriveManager. A tool tip will then appear showing the faulty feedback
system. The IDN P-0-0150 described below applies to feedback system 1. The IDN
P-0-0180 applies to feedback system 2 and has the same structure as P-0-0150.
Open the System Manager and select the servo drive (1) which is generating the error. Open the
TCDriveManager (2) and select the faulty feedback (4) in the affected channel (3). In the IDN "P-0-0150" (5)
under the "Sin / Cos" parameter (6) open the value range (8) under the Parameter "SinCos 1Vss monitoring".
Four options appear.
Advanced system characteristics
Servo Drives AX5000180 Version: 2.4
0 = Error monitoring (full error monitoring)
1 = Error monitoring and Sin/Cos logging (full error monitoring and logging of sin/cos signals)
2 = Error monitoring (only wire break detection) and Sin/Cos logging (only wire break detection and logging
of sin/cos signals)
3 = Error monitoring (only wire break detection)
To log the Sin/Cos signals, select either 1 or 2.
Whether to select option 1 or 2 should generally be decided depending on the application. However, there
are two rough indications for making the choice:
If the faulty axis can no longer be used because the error always occurs immediately, then you need to
select the "2 = (only wire break detection and logging of sin/cos values)" option so that the error can occur
and be logged.
If the faulty axis can be operated because the error only occurs sporadically, then you can select "1 = (full
error monitoring and logging of sin/cos values)" or "2 = (only wire break detection and logging of sin/cos
values)" so that the error can always be logged.
WARNING
Warning, risk of injury from uncontrolled movements!
If a faulty axis is used then this axis may make uncontrolled movements. Make sure that no
one is in the machine's traversing range.
In many cases the faulty axis can also be moved manually and this option should be used preferentially for
safety reasons.
Adding the debug pointer to the Startup list
In order for the sin/cos signals to be logged, the relevant debug pointers must be added to the AX5000
Startup list. Call the Startup list in the TCDriveManager using the button (9) and click on "Add" (10). A
window opens with a list of parameters including P-0-1006 to P-0-1010 (11).

10.2 EtherCAT
10.2.1 Parameter handling
The servo drives from the AX5000 series use a new method for managing their configuration parameters
(IDNs).
In contrast to conventional servo drives (e.g. AX2000), these parameters are not stored in a non-volatile
manner on the AX5000 itself, but they are transferred from the controller to the drive whenever the EtherCAT
fieldbus system starts up. This approach has the advantage that the parameter management takes place
exclusively in the corresponding TwinCAT project, without the need for separate data backup of drive
parameters. If a replacement is required, it is sufficient to replace the servo drive. There is no need to load
parameters onto the servo drive.
The parameters are transferred from the controller to the servo drive when the EtherCAT system starts up.
Due to the high data transfer rate offered by EtherCAT this process is very fast, even in larger systems.
Transitions
During startup the EtherCAT system passes through the following states: Init, Pre-Operational, Safe-
Operational, and Operational (see chapter EtherCAT state machine).
The diagram shows the following transitions:
IP: Transition from Init to Pre-Operational
PS: Transition from Pre-Operational to Safe-Operational
SO: Transition from Safe-Operational to Operational
OS: Transition from Operational to Safe-Operational
SP: Transition from Safe-Operational to Pre-Operational
PI: Transition from Pre-Operational to Init
In practice the parameters (IDNs) are transferred from the higher-level control system to the AX5000 during
transitions IP, PS and SO.
The TwinCAT System Manager indicates at which transition the individual AX5000 parameters can be
transferred.

10.2.2 EtherCAT synchronization
The EtherCAT master sends EtherCAT telegrams to all connected EtherCAT slaves. In each slave an
EtherCAT slave controller (ESC) is implemented. In order to achieve high positioning precision and meet
stringent demands in terms of concentricity characteristics, it is necessary for the set value generation in the
master and all connected drives to be synchronized. In the EtherCAT system the so-called distributed clocks
are available for this synchronization task. For details see www.ethercat.org. The following description deals
exclusively with the synchronization of the data.
EtherCAT Master
From the TwinCAT project and the ESI files (EtherCAT slave information) of the connected slaves, the
System Manager determines the required parameterization for the distributed clocks of the connected
EtherCAT slaves when the configuration is generated. This parameterization is transferred to the slaves or
their slave controllers via Init commands whenever the EtherCAT segment starts up. Manual adjustment is
not required and should only be carried out in consultation with AX5000 support.
Advanced system characteristics
Servo Drives AX5000 187
Version: 2.4
EtherCAT slave controller (ESC)
The EtherCAT slave controller (ESC) of the AX5000 is parameterized by the master such that two
synchronization signals (Sync0 and Sync1) are generated. These signals are analyzed by the CPU and then
synchronized with the internal control algorithms.
Sync0
The "Sync0" signals are sent every 250 µs as standard. If a signal fails to materialize, the CPU generates the
error code F414, and the axes of the servo drive are stopped with the "EStop ramp".
Additional error messages:
The Sync0 cycle time may only be configured with 62.5 µs, 125 µs or 250 µs, otherwise the CPU generates
the error code F409.
If the signal "Sync0" is not activated in the ESC, the CPU generates the error code F410.
If the pulse length of the signal no longer conforms to the standard, the CPU generates the error code F411.
In the case of each error message the axes are brought to a standstill with the "EStop ramp".
Sync1
The "Sync1" signals are parameterized according to the NC cycle time as standard. This cycle time is always
a multiple of Sync0. If a signal fails to materialize (see F1), the CPU also generates the error code F414, and
the connected axes are stopped with the "EStop ramp".
Additional error messages:
The Sync1 cycle time must be a multiple of the Sync0 cycle time and must be identical to the parameters
"S-0-0001 and S-0-0002", otherwise the CPU generates the error code F412.
If the signal "Sync1" is not activated in the ESC, the CPU generates the error code F413.
If the pulse length of the interrupt no longer conforms to the standard, the CPU generates the error code
F411.
In the case of each error message the connected axes are brought to a standstill with the "EStop ramp".
End of telegram (EOT)
The EtherCAT state controller (ESC) in the slave processes the EtherCAT telegrams dynamically. At the end
of the telegram (EOT) it transfers the content to the addressed Sync Manager (if the telegram was intended
for this slave and no CRC error is present). The EOT thus lags slightly behind the signal of Sync1 by the time
DT2; the status of SyncManager2 is subsequently set to "SyncManager written". The CPU only copies the
data from SincManager2 into its own memory area if this status is "SyncManager written" at the time of
Sync1. At the time of the Sync1 signal, the CPU expects a written SyncManager2. The end of the telegram
must therefore occur just before the Sync1 signal is generated. The data are not copied if the status is not
"SyncMan written"; if the data cannot be copied twice in succession, the CPU generates the error code F415
and the connected axes are brought to a standstill with the "EStop ramp".
Note
Jitter!
The tolerance for the existence of new data at the right time, due to "jitter" etc., is NULL.
The EtherCAT master must ensure that the data arrive at the SyncMan2 in time.

Special notes concerning the diagnostic message F415 "Distributed Clocks: process
data synchronization"
The real-time behavior of the machine is continuously monitored during operation. An important component
of this monitoring is the synchronization of all hardware and software components involved in data transfer.
The illustrations below represent a simplified example of this data transfer. The focus is on the drive tasks
"NC" and "PLC".
Sample 1
1. The CPU timer sends interrupts on a regular basis (default: base time = 1 ms)
2. The individual tasks are now processed in accordance with the rules of task management.
3. Task management:
Since the task takes up a greater or smaller amount of time due to a higher or lower number of com-
puting processes, the "I/O update" should be parameterized directly after the entry point (a) at the start
of the task. This excludes one source of incorrect synchronization.
A further source of error is an unfavorable prioritization of the individual tasks (see below).
4. Following the "I/O update", the resulting data are transferred to the TwinCAT-IO system and subse-
quently dispatched by EtherCAT telegram to the connected devices. The EtherCAT telegram passes
through each physically connected device and hands over or picks up only the data for this device.
Advanced system characteristics
Servo Drives AX5000 189
Version: 2.4
5. The order of task calculation depends among other things on the prioritization of the tasks. If a task
has a higher priority, it is also calculated first and can send its data to the TwinCAT-IO system, which
then dispatches the telegram. Problems usually occur when individual tasks have different cycle times;
see below.
Prioritization
The following graph describes the effects of prioritization on the synchronization of the data.
Assumptions:
Sync1 = 3 ms
NC cycle time = 3 ms
NC priority = 10
PLC cycle time = 2 ms
PLC priority = 5
NC data are to be transmitted cyclically to the drive. Although the PLC requires time to compute, no data are
transmitted to the drive.
Due to its higher priority, the PLC task is always calculated before the NC task; these tasks affect each other
at the start point time "0 ms" and then repetitively every "6 ms", i.e. 2x Sync1. However, the ESC expects the
EtherCAT telegram with the NC data at each Sync1 (3 ms). That is not ensured, however, because the more
highly prioritized PLC task is always calculated before the NC task and thus in the case of synchronous
mapping the telegram start is delayed. For this reason the NC telegram arrives somewhat later every 6 ms
and can thus cause the F415 error in the AX5000.

Due to its higher priority, the NC task is always calculated before the PLC task and the telegram is
accordingly also sent first; these tasks affect each other at the start point time "0 ms" and then repetitively
every "6 ms", i.e. 2x Sync1. However, the ESC expects an EtherCAT telegram at each Sync1 (3 ms). This is
not a problem in SyncUnit 1, which is served by the NC, since the more highly prioritized NC always sends
the telegram in the same time pattern. However, the PLC telegram arrives somewhat later every 6 ms and
can thus cause the F415 error in the AX5000 in SyncUnit 2.

A cascaded controller structure consisting of current, speed and position controllers has proven to be
necessary for achieving high dynamics and positioning accuracy. The diagram illustrates the time constants
of the individual control loops, rising from inside to outside. Two operating modes are suitable for positioning:
velocity set value specification or position set value specification.
For the position of operation, 2 modes are:
• • speed setpoint (speed interface):
Cyclic speed setpoints are sent from the controller to the drive. Of the Position controller is in this case
on the side of the controller (NC) implemented.
• • Position setpoint. (Position interface):
Cyclic setpoint positions are sent from the controller to the drive. The position controller is here
implemented in the drive. In the control (NC) only the setpoint profile is calculated. Here is a higher
bandwidth in the position control achieved (no EtherCAT dead in closed Loop). This mode should
always be used when the controller enables.
Profile generator
The profile generator generates curve profile of a positioning job of the PLC function block
MC_MoveAbsolute. In each NC cycle, at a specified time (node T1 - Tn), the Setpoints this positioning task
passed to the axis control. Thus, the servo amplifier optimally can proceed, the target values of the profile
generator with the SAF task of the EtherCAT fieldbus must be triggered. The SAF task ensures that the
support points (T1 - Tn) to the servo amplifier be transported.

right side of the navigation rocker . Except with the standard display, if you do not change the display
for approx. 25 seconds, the standard display is automatically shown again. The standard display is always
shown if the device is working perfectly.
Display Description
The display consists of 2 lines. These two lines display independent,
configurable contents.
The contents can be arranged into 4 groups.
Cyclic values (standard display):
The so-called standard display is shown permanently. The values provided can
be displayed in the two lines. The two lines are preconfigured in the factory as
follows:
Line 1: EtherCAT status
Line 2: DC link voltage
Error messages:
If an error occurs, the diagnostic code (hex) and a short version of the message
(2+3) are shown alternately on the display. If the error concerns only channel
"A", then this display is shown only in the upper line; the standard text remains in
the lower line. If the error concerns only channel "B", then this display is shown
only in the lower line; the standard text remains in the upper line. In both cases
the display additionally flashes (2-5).
If the error has been rectified and acknowledged with the reset command
(S-0-0099), the standard display with the cyclic values appears again (see
above).
see error messages Warnings:
If a warning occurs, the display behaves in the same way as with an error
message.
see error messages Information messages:
If an information message occurs, the display behaves in the same way as with
an error message, but does not flash.

Cyclic values
The two lines with the cyclic values, which are shown on the standard display, are freely configurable. You
can choose from 51 different cyclic values. The values are saved in IDNs and retrieved from there. The
procedure for configuring line 1 and line 2 is identical:
Overview (example)
Changing the display
Starting from the standard display, press the right-hand side of the rocker 1x (for line 1) or 2x (for line
2); the display or appears.
Display Description
1 = "M" indicates that the "menu mode" is activated.
2 = The "CycValuesLine1" menu is active. This means that the cyclic values are
displayed in line 1.
3 = Indicates which cyclic values are currently displayed.
The currently displayed value determines the point of entry into the list of the cyclic values. You can change
to the next cyclic value with the bottom or the top side of the rocker, as shown below. If the
desired value has been reached, press the center of the rocker for 3 seconds. The value is adopted
and the changed standard display is shown.

Error reset (command S-0-0099)
After rectifying an error, it is necessary to perform an error reset. The associated command is the IDN
S-0-0099. This command can also be given directly via the display. As soon as an error occurs the display
flashes continuously; the standard display is shown again and the flashing stops only after a successful error
reset.

10.5 Motor brake management
10.5.1 IDNs involved
IDN Name
S-0-0206 Drive on delay time
S-0-0207 Drive off delay time
P-0-0058 Motor brake type
P-0-0096 Motor control word
P-0-0097 Motor status word
10.5.2 Functioning
IDN S-0-0206 determines the time of the motor standstill after the motor current feed, so that the brake can
vent first.
IDN-S-0-0207 defines the switch-off delay between activation of the motor brake and deactivation of the
current feed.
IDN-P-0-0058 is used to configure the motor brake.
IDN-P-0097 displays the state of the motor brake.
IDN-P-0096 can be used to release the motor brake manually or requesting activation of the brake manually.
This bits overwrite the internal brake request. The brake is therefore released or engaged irrespective of the
motor current feed and any travel command.
WARNING
Risk of injury!
Improper operation of IDN P-0-0096 can therefore lead to sagging of a non-energized Z
axis or closing of the motor brake at full speed!
10.6 Commutation methods
The important characteristics of a servomotor, such as its very smooth running, high efficiency and optimum
thermal utilization, are strongly influenced by the commutation. Commutation refers to the transfer of current
from one winding to the next. The moment at which commutation takes place must be harmonized with the
magnetic field of the rotor if the servomotor is to operate most effectively.
10.6.1 Rotary servomotors
10.6.1.1 Mechanical commutation
These motors, which use brushes, generate the alternating fields necessary for operation of the motor
through sliding contacts, whose geometrical arrangement switches the current paths. Brush losses and wear
are disadvantages of this simple, mechanical commutation method.
10.6.1.2 Electronic commutation
These modern motors generate the alternating field needed for operation of the motor by means of an
electronic circuit which is not subject to either wear or friction. The type of motor and the encoder system in
use determine the commutation method.
Advanced system characteristics
Servo Drives AX5000 201
Version: 2.4
Absolute encoder system (motor feedback) within one rotation
Samples of this type of encoder system includes: Resolver, EnDat, BiSS and HIPERFACE
Two different commutation methods are involved here:
Mechanical adjustment of the encoder
The motor's encoder system is mechanically adjusted at the factory (the encoder and rotor are matched to
one another), but the rotor position is unknown.
The commutation angle is determined once by the P160 command, using the IDN "P0-0-165_Command
mode_Static current vector" and the IDN "P-0-057 "Electrical commutation offset". This means that the
corresponding mechanical angle coming from the encoder system is displayed and read out in P-0-0058,
and is saved in the IDN "P-0-0150_Parameter chanel_Adjustable commutation offset" (motor database). In
order for the parameter to be used, the IDN "P-0-0150_Parameter chanel_Commutation mode" (motor
database) must be set to 3: "Adjustable offset". The associated value of the IDN "P-0-057 "Electrical
commutation offset" is also saved in the motor database.
Electronic adjustment of the encoder system
Note
Synchronous motors!
Electronic adjustment is only required for synchronous motors. In the case of a synchro-
nous motor, the magnetic field of the rotor is generated electronically, and therefore can be
set appropriately for the electromagnetic field of the winding.
Depending on the encoder system there are, again, two different commutation methods:
1. The encoder is always attached to the rotor by the manufacturer in the same rotary position, but the
rotor position is not known.
The commutation angle is determined once by the P160 command, using the IDN "P0-0-165_Com-
mand mode_Static current vector" and the IDN "P-0-057 "Electrical commutation offset". This means
that the corresponding mechanical angle coming from the encoder system is displayed and read out in
P-0-0058, and is saved in the encoder system's data store (exceptionally) and in the IDN
"P-0-0150_Parameter chanel_Adjustable commutation offset" (motor database). In order for the pa-
rameter to be used, the IDN "P-0-0150_Parameter chanel_Commutation mode" (motor database)
must be set to 3: "Adjustable offset". The associated value of the IDN "P-0-057 "Electrical commuta-
tion offset" is also saved in the motor database. This method requires a encoder system having a data
store and a data line.
2. The angle between the encoder system and the rotor is determined by the motor manufacturer using a
command that is specific to the encoder, and is communicated to the encoder system. The encoder
system stores this angle, using it for internal calculation, but the rotor position is unknown.
The commutation angle is determined once by the P160 command, using the IDN "P0-0-165_Com-
mand mode_Static current vector" and the IDN "P-0-057 "Electrical commutation offset". This means
that the corresponding mechanical angle coming from the encoder system is displayed and read out in
P-0-0058, and is saved in the encoder system's data store (exceptionally) and in the IDN
"P-0-0150_Parameter chanel_Adjustable commutation offset" (motor database). In order for the pa-
rameter to be used, the IDN "P-0-0150_Parameter chanel_Commutation mode" (motor database)
must be set to 3: "Adjustable offset". This angle is always included in internal calculation processes.
This method requires an intelligent encoder system.
Non-absolute encoder system (feedback) within one rotation
Samples of this type of encoder system includes: SIN / COS 1Vss
In this case, a special commutation procedure (wake&shake) must be run in order to determine the
commutation angle. This angle is stored internally, and is taken into account during operation. If the AX5000
is switched off, or if the "EtherCAT-State machine" is switched into "Pre-op" or a lower state, the
commutation angle will be lost because the encoder system is not absolute. "Wake&shake" can only operate
without error when the drive system is running steadily; in other words there must not be any vibrations
affecting the motor from outside. In addition, a stability investigation using the default values of the "IDN
P-0-0165" is necessary the first time the system is operated.
Advanced system characteristics
Servo Drives AX5000202 Version: 2.4
Note
Oscillatory system!
It is important for this stability investigation to examine the application in advance and to
determine the oscillation that is potentially most problematic. This case can occur under
load conditions, or may be found when unloaded.
WARNING
Warning, risk of injury from uncontrolled movements!
In the method described below, the motor shaft is brought directly to a certain position.
Make sure that your application permits this movement, secure the surroundings to prevent
unintentional entry, and make sure that nobody is in the hazardous area.
Oscillatory system
It is necessary to analyze the vibration pattern of an oscillating system, and to take appropriate damping
measures. Oscillations always have their effect in Phase 2 of "wake&shake"; oscillations are not particularly
critical in Phase 1.
Decaying oscillation
The amplitude (k) and the decay time (l) of this
kind of oscillation must be found. The parameters
IDN-P-0-0165 "Commutation pos control: Kp" can
affect both the amplitude (k) and the decay time
(l). The parameter IDN-P-0-0165 " Second phase
duration" should be greater than the decay time
(l).
Constant oscillation
This kind of oscillation is unacceptable, as a
stable regulation process is not established. The
parameters IDN-P-0-0165 "Commutation pos
control: Kp" must be checked, and modified if
necessary. If this does not achieve the desired
result, you must damp the vibration mechanically.
Rising oscillation
This kind of oscillation is unacceptable, as a
stable regulation process is not established. The
parameters IDN-P-0-0165 "Commutation pos
control: Kp" must be checked, and modified if
necessary. If this does not achieve the desired
result, you must damp the vibration mechanically.
The motor shaft is brought to freely definable electrical positions by impressing an appropriate current in the
course of this investigation. When this injected current is switched off, the motor should remain in the
position that it has reached. BECKHOFF recommends positions of 0°, 90°, 180° and 270°. In critical
applications, eight positions (0°, 45°, 90°, 135° ...315°) should be selected instead of four. The current
injection is parameterized in the IDN P-0-0165 under "Static current vector", while the freely selectable
electrical position is set in the IDN P-0-0057. "Wake&shake" should be carried out in each position; stability
of the system is only ensured when this has been done successfully.
Advanced system characteristics
Servo Drives AX5000 203
Version: 2.4
Wake&shake
Note
Oscillating system!
A mechanical remedy must be provided if the application oscillates. You can carry out the
commutation up to a degree using wake&shake, but should carefully select the parameters
for the IDN "P-0-0165" to make the effect of the oscillation as small as possible, since too
much post-pulse oscillation will cause a commutation error. This is because the angle mea-
sured after completing the command will be entered as the commutation angle.
WARNING
Warning, risk of injury from uncontrolled movements!
The motor shaft will be moved in steps during the process described below. In Phase 1 the
maximum electrical movement is 8 x (the value from "P-0-0-0165_Fist phase position moni-
toring limit"). In Phase 2it is 0.5 x (the value from "P-0-0-0165_Fist phase step width"). This
formula can only be applied if the previous investigation of stability has been concluded sat-
isfactorily. Make sure that your application permits this movement, secure the surroundings
to prevent unintentional entry, and make sure that nobody is in the hazardous area.
The wake&shake commutation function consists of two phases. An approximate determination of the rotor
position is carried out in Phase 1, while Phase 2 determines the position more precisely. The aim of the
commutation function is to determine the precise position of the rotor with a minimum amount of movement.
Due to the pairs of poles, servomotors exhibit a direct relationship between the electrical and mechanical
rotation. One electrical rotation always corresponds to one mechanical rotation divided by the number of pole
pairs. A motor with a single pair of poles is illustrated in the following example for the sake of simplifying the
calculation.
Parameterization is carried out using the IDN P-0-0165 "Commutation offset calibration parameter". The
quoted angles always refer to electrical rotations!

Step 1:
= see IDN P-0-0165 parameter description above
= flux vector of the rotor with permanent magnet.
Sequence:
A current vector "a" is developed during the time "b". Due to the
rising magnetic force, the rotor "c" is turned in the direction of the
current vector "a". The direction of rotation "d" is transmitted to the
feedback system and the AX5000, where it is stored.

Sequence:
A current vector "a" is developed during the time "b". Due to the
rising magnetic force, the rotor "c" is turned in the direction of the
current vector "a". The direction of rotation "d" is transmitted to the
feedback system and the AX5000, where it is stored and analyzed.
If the analysis shows that the direction of rotation "d" of the rotor "c"
has not changed when compared with that of the previous
impressed current, the process continues.
Step 3:
= see IDN P-0-0165 parameter description above
= flux vector of the rotor with permanent magnet.
Sequence:
The current vector "a" is again set to the magnitude "e" in the
direction of the rotor "c".
The current vector "a" is now again developed during the time "b".
Due to the rising magnetic force, the rotor "c" is turned in the
direction of the current vector "a". The direction of rotation "d" is
transmitted to the feedback system and the AX5000, where it is
stored and analyzed. In this case, the analysis shows that the
direction of rotation "d" of the rotor "c" has changed when
compared with that of the previous impressed current. As a result,
the sector in which the rotor "c" is located has been found, and
Phase 1 is therefore completed.

Phase 2 - precise determination of the rotor position (motor shaft)
There are two variants of the precise localization that may be used in Phase 2. In the first variant, the rotor
only makes minimal movement, but this does require a very stable system with only a slight tendency to
oscillate. In the second variant, the rotor can move by up to a maximum of half the sector , but this
method is much more tolerant against oscillation.
The value set in the parameter IDN-P-0-0165 "Commutation pos control: Kp" controls which variant is used:
IDN-P-0-0165 "Commutation pos control: Kp" > 0 --> Variant 1

Sequence:
The current vector "g" is developed starting from
the final position of the current vector "a" in Phase
1. Due to the rising magnetic force, the rotor "c" is
turned in the direction of the current vector "g". The
movement is passed through the feedback system
to the AX5000, and supplied to a control loop. This
control loop immediately corrects the direction of
the current vector. This algorithm is executed until
the parameterized current intensity is achieved, and
the current vector approximately coincides with the
flux vector. The current is now maintained over the
period "h" which ensures that optimum
commutation takes place. In this control algorithm,
the rotor only moves minimally through "i".

the sector "e", and this current is developed. Due to
the rising magnetic force, the rotor "c" is turned in
the direction of the current vector "g" until they
coincide. In this static alignment, the rotor cannot
move more than half the width of the sector "e".

10.6.2 Linear motors
The above description of the commutation process applies equally to rotary motors and to linear motors.
Depending on the construction, there are merely some differences of nomenclature (e.g. motor shaft (rotor) =
primary part; "degree" = "mm" (conversion is needed))
WARNING
Warning, risk of injury from uncontrolled movements!
The primary part is moved in steps during "wake&shake". In Phase 1 the maximum electri-
cal movement is 8 x (the value from "P-0-0-0165_Fist phase position monitoring limit"). In
Phase 2it is 0.5 x (the value from "P-0-0-0165_Fist phase step width"). This formula can
only be applied if the previous investigation of stability has been concluded satisfactorily.
Make sure that your application permits this movement, secure the surroundings to prevent
unintentional entry, and make sure that nobody is in the hazardous area.
Advanced system characteristics
Servo Drives AX5000210 Version: 2.4
Linear motors consist of a secondary assembly, whose position is fixed, onto which permanent magnets are
attached with alternating polarity and regular spacing. A primary assembly can undergo translatory
movement above this magnetic field. This movement is created by generating an electromagnetic field in the
primary assembly. Linear motors always have only one pair of poles, and the distance between the poles
therefore corresponds to one electrical rotation.
The "Electronic Commutation" section above can be applied to linear motors.
10.6.3 Commutation error "F2A0"
During operation of the motor the commutation is permanently monitored. The following conditions must
apply in order for the AX5000 to detect a commutation error:
1. The current velocity must be higher than the limit speed set in the IDN "P-0-0069 Commutation moni-
toring"
2. The power and acceleration vectors must have different signs.
3. The current power is greater than 95% of the value in the IDN "P-0-0092 Configured channel peak
current".
When these three conditions apply it is very likely that there is a commutation error and that the motor is
undergoing uncontrolled acceleration; the AX5000 generates a commutation error and switches the motor
torque-free i.e. it stops without control.
WARNING
Warning, risk of injury from uncontrolled movements!
A certain distance will have been travelled from the point when the error is detected until
the motor stops. Make sure that your application permits this movement, secure the sur-
roundings to prevent unintentional entry, and make sure that nobody is in the hazardous
area. This applies in particular to vertical axes.
Note
Occurrence of commutation error
A commutation error almost always occurs when the axis is commissioned. If this error oc-
curs during regular operation of the axis then special measures need to be adopted. See
next chapter.
Advanced system characteristics
Servo Drives AX5000 211
Version: 2.4
10.6.4 Commutation error during regular operation (very rare)
Under special operating conditions the regular operation of the axes can fulfil the three conditions cited
above and therefore trigger this error message despite correct commutation. A number of examples are
given below which, however, occur very seldom:
1. When the servo drive is operating at the limit (conditions 1 and 3 are met) and external forces cause
an opposing torque which then fulfils condition 2, the servo drive generates a commutation error.
2. The servo drive is operating at the limit (conditions 1 and 3 are met) and an oscillating current is pro-
duced due to a rapid change of direction or speed. Condition 2 is then also met and a commutation er-
ror arises.
If these examples do not apply to your application, analyze the application and try to find the cause. If you
are unable to remedy the cause but still wish to operate the axis, there is only one option for suppressing the
commutation error:
Parameterize the value of the IDN P-0-0069 to the permitted maximum speed of the motor so that point 1 of
the above-mentioned factors cannot apply and the commutation error will no longer appear.
WARNING
Warning, risk of injury from uncontrolled movements!
Increasing the value of the IDN "P-0-0069" to the highest speed always means that the
commutation monitoring will no longer cause errors, even when other conditions actually
call for this. This is particularly critical when the motor is being replaced. If the value of the
IDN "P-0-0069" is NOT reset, then uncontrolled movements of the motor may occur. Beck-
hoff recommends that you should NOT increase the value of the IDN "P-0-0069".
Note
Drive design
As a rule the drive should not be designed at the limit i.e. the current power should reach a
max. of 90% of the P-0-0092 "Configured channel peak current" value.

10.9.5 Personnel qualification
This description is only intended for trained specialists in control, automation and drive engineering who are
familiar with the applicable national standards. Knowledge of machine safety legislation is compulsory.
10.9.6 Product description
The AX5801 Safety Card from Beckhoff is used to realize the safe stop functions "STO or SS1 according to
IEC 61800-5-2". STO stands for SafeTorqueOff, SS1 for SafeStop1.
Thanks to the integrated two-channel monitoring of the AX5000, you can realize stop category 0 or 1
according to IEC 60204-1 with minimum effort and further TwinSAFE blocks from Beckhoff, thereby
achieving category 4, PL e according to ISO 13849-1:2006.
Two-channel monitoring is achieved through certified relays (Rel1 and Rel2). The relays are equipped with
positively driven contacts including feedback contacts (K1 and K2). The feedback contacts are connected in
series and potential-free with terminals (5) and (6) of the 6-pin connector.
The two coils (S1 and S2) have to be supplied with 24 V DC via terminals 1 and 2 or 3 and 4 of the 6-pin or
4-pin connector. Terminals 1-1, 2-2, 3-3 and 4-4 of the two connectors are bridged internally. If a relay
releases, the de-energizing circuit of the AX5000 servo drive range ensures that the connected motors (both
channels) become torque-free.

10.9.8.2 Electrical installation
Configure the safety operation of servo drive via IDN P-0-2000. During the next system start-up the servo
drive automatically detects whether a Safety Card was inserted and whether the IDN P-0-2000
parameterization is correct. Error message "0xFDD4" indicates incorrect configuration. If the servo drive with
the Safety Card does not reach the safe state, error message "0xFDD5" appears on the display of servo
drive. In this case please contact Beckhoff.
CAUTION
Danger for persons and equipment!
If an error message appears on the display of the AX5000 the servo drive must not be put
into service if the servo drive in the system or machine represents a safety-relevant part of
the control system.
10.9.9 Application example (emergency stop – stop category 1)
Components involved:
• Emergency stop device (control switch S1) according to ISO 13850 and control switch S2
• 1 safety input terminal (KL1904) and 1 input terminal (KL 1404)
• 1 safety logic terminal (KL6904) with function block "ESTOP"
• AX5801 Safety Card and servo drive from the AX5000 range
• Programmable logic controller (PLC) and EtherCAT fieldbus
By activating the emergency stop device (S1) inputs EStopIn1 and EStopIn2 of FB "ESTOP" are switched to
state "0", resulting in outputs EStopOut and EStopDelOut of FB "ESTOP" being switched to state "0". As a
result, a quick stop command is issued to the PLC and therefore the AX5000 via EtherCAT. The output
EStopDelOut of FB "ESTOP" ensures that after a specified delay time the 24V supply of the AX5801 Safety
Card is interrupted. This causes the relays (REL1 and REL2) to release and both channels (motors) to be
made torque-free via the internal deactivation procedure of the AX5000.
In the event of a fault the controlled shutdown (quick stop) may fail. The Safety Card becomes active once
the delay time has elapsed, and all motors connected to the device run out. The risk analysis for the machine
must indicate that this behavior can be tolerated. An interlock may be required.
The delay time must be set slightly longer than the maximum braking time of the quick stop.
Sticking relay contacts on the Safety Card are detected via input EDM1 of FB "ESTOP", and restarting is
prevented.
When the emergency stop device is released again, the control switch (S2) must be operated (first rising
then falling edge at the restart input of FB "ESTOP") in order to restart the AX5000.

Project planning
Servo Drives AX5000220 Version: 2.4
11 Project planning
11.1 Important information for project planning
The more thoroughly a machine or plant project is thought through in advance, the less risk there is of having
to carry out expensive modifications during or after commissioning. This applies to both the mechanical and
electrical design. This chapter can only provide a brief overview of electrical project planning.
11.2 Drive train design
Application, servo drive, motors and gear mechanism must be adapted to each other so that there is an
adequate safety margin for all components as a degree of sluggishness appears over time due to high
temperatures or wear. Make sure that the components in the working area of the system have adequate
reserves so that the working life is not impaired and the necessary control quality can be maintained.
11.3 Energy management
If the quality of the mains supply is impaired due to wide fluctuations in voltage, then both the servo drive
specification and the speed range of the motor will need to be considered. With a positive tolerance for
voltage fluctuation the upper limit value of the wide voltage input of the AX5000 needs to be taken into
account. With a negative tolerance of the voltage fluctuation it must be checked whether the decrease in
speed caused by the low voltage is permissible. With these motors what is known as field weakening
operation (check availability) of the servo drive may provide a solution. If the mains supply does not meet the
specifications for operation of the AX5000, then isolating transformers, mains chokes, mains filters or other
measures may be required.
Note
Only AX5101 – AX5140!
An energy efficient drive system operates in a drive system with a shared DC link and
shared internal and possibly also external brake resistors or brake modules. If you are al-
ready using similar drive systems, the AX5000 offers a convenient diagnostic system for
determining the load on the brake resistors and for transferring the values. Previous experi-
ence with drive systems shows that in such a system much smaller or even no external
brake resistors / brake modules need to be used.
11.4 EMC, earthing, shield connection and potential
Note
EMC information of the servo drive AX5000!
For further information, please read the EMC – information brochure of the servo drive
AX5000. You will find the document on the Beckhoff homepage (www.beckhoff.com) under:
Motion → Documentation → EMC – leaflet.
11.5 Control cabinet
The dimensions of the control cabinet must be sufficient to accommodate all components with the specified
distances. Remember that high temperatures may necessitate forced cooling. Position the control cabinet as
close as possible to the machine so that the motor cables can be as short as possible.
In addition, the control cabinet should have an earthed metal rear panel to which the AX5000 incl. periphery
are attached so that safe earthing can be guaranteed. If you are unable to guarantee these conditions you
need to earth the AX5000 and the relevant components using an approved cable of adequate size.

12.2 Brake module - AX5021-0000
Figure Art.-No. Description
AX5021-0000-0000 Using a brake module it is possible to take up additional braking
power in a drive system, because the connection of an external
brake resistor without a brake module in a drive system with
devices up to max. 25 A rated current is not permissible. A
further advantage is the simple installation and the small space
requirement of the brake module. The brake module is equipped
with a complete DC link and an internal brake resistor and
enables the connection of an external brake resistor with the
integrated brake chopper. Several brake modules can be
integrated into a drive system.
Note
Operating conditions
The brake module may only be used together with servo drives of the AX51xx-xxxx-02xx or
AX52xx-xxxx-02xx series. These devices have serial numbers above 100.000. In addition
to the AX5021, the drive system must include at least two further servo drives from the
AX5000 range.

12.2.5 Electrical connection (example)
DANGER
Serious risk of injury through high electrical voltage!
Due to the DC link capacitors dangerous voltage may persist at the DC link contacts "X02"
after the servo drive has been disconnected from the mains supply. Wait 5 minutes after
disconnection and measure the voltage on the DC link contacts DC+ and DC-. The device
is safe once the voltage has fallen below 50 V.
The example below describes the brake module and several servo
drives, which are linked via AX-Bridge modules to make up a drive
system. We recommend that the brake module be placed in the
first position with the AX-Bridge power supply module (AX5901)
and after that the servo drives with decreasing rated current; we
assume here that the most powerful servo drive also releases the
greatest brake energy.
CAUTION!
Uncontrolled movements!
If the drive system is disconnected from the mains due to a mains
failure, all axes of the drive system make uncontrolled movements.
Take suitable measures to ensure than no persons are endan-
gered during this time. Vertical axes are particularly dangerous.

12.2.8 Operation modes of the AX5021
It can be assumed that a brake module is used only if the brake energy cannot be dissipated despite a DC link system and internal
brake resistors. The brake module can be operated in two different operation modes, which have a direct influence on the energy man-
agement. The operation modes can be selected when using the external brake resistor. The following sketches show the storage ca-
pacity of the DC link of the individual devices in relation to the operation modes.
Ext. brake resistor enabled (system / standard)
In this operation mode the capacity of the DC link of the brake
module is reduced by approx. 10%. At 90% DC link load the brake
chopper then directs the generated braking energy to the external
brake resistor and, when this has reached its capacity limit, into the
internal brake resistor. In this case the brake energy is first fed into
the brake module, since the brake choppers in the other servo
drives are only activated at 100% utilization of the DC link. This op-
eration mode is set as the default, because no further configuration
of the devices in the DC link system is necessary apart from the
basic configuration of the brake module. If the external brake resis-
tor of the brake module is mounted outside the control cabinet,
then the thermal load in the control cabinet is also lower.
Ext. brake resistor enabled (standalone brake chopper)
In this case the capacity of the DC links is fully utilized. This opera-
tion mode must be selected and, apart from the basic configuration
of the brake module, the internal brake resistors of the devices in
the DC link system should be deactivated, as otherwise the ther-
mal load in the control cabinet will also increase. In order to reduce
the thermal load further, it is a good idea to mount an external
brake resistor on the brake module outside the control cabinet.

DANGER
Caution - Danger of death!
Even when the AX5000 is disconnected from the mains voltage, dangerous voltage contin-
ues to be present at the "X02" terminals of the DC link for at least 5 minutes. Wait until the
DC link capacitors are discharged before touching live terminals. The voltage measured be-
tween the DC+ and DC- terminals (X02) must have dropped to below 50 V.
WARNING
Caution - Risk of injury!
Electronic equipment is not fail-safe. The machine manufacturer is responsible for ensuring
that the connected motors and the machine are brought into a safe state in the event of a
fault in the drive system.

12.4 Optional encoder card - AX5721 / AX5722
Figure Art.-No. Description
AX5721-0000 encoder option card for one additional
encoder input EnDat 2.2, BiSS C
The optional encoder card enables connection of
an additional feedback systems per channel. The
system parameters match the standard parame-
ters that are analyzed via inputs X11 and X21.
Through simple configuration via jumpers up to
six further digital inputs (In "A" to In "F") can be
analyzed, which are provided through special
feedback systems via parameter channels. The
X41 and X42 sockets are compatible with the
plugs of the X11 and X21 front sockets of the
AX5000, which means that the tried and tested
cables from the ZK4510 series can be used. To
analyze the additional digital inputs you simply
have to insert an adapter or establish a suitable
wiring. This optional card cannot be used as
commutation feedback system (primary).

12.5 External Brake Resistor AX2090-BW5x
Figure Art.-No. Description
AX2090-BW5x The external brake resistors of the AX2090-BW5x
series are able to convert the dynamic energy
generated during braking of a servomotor into heat.
The built-in temperature switch enables the system to
respond immediately to any overload of the brake
resistor through analysis in the AX5000 or the PLC.
All brake resistors of the AX2090-BW5x-xxxx series
are UL and CSA approved.
Attention
Caution - Destruction of the equipment
The brake resistor may only be connected to individual AX5000 devices or AX5021 brake
modules. It must never be used in a drive system without the AX5021 brake module, since
this may lead to its destruction through overload.
Attention
Caution - Destruction of the brake resistor and consequential damage
The built-in temperature switch must be monitored, so that the machine can be stopped in
a controlled manner and switched off in the event of an overloading of the brake resistor.
12.5.1 Appropriate use
The brake resistors from the AX2090-BW5x-xxxx series are exclusively designed for direct application with
an AX5000 series servo drive or the AX5021 brake module. They are designed for installation as
components in electrical installations and machines together with the servo drive or the brake module, and
this is their only purpose.
12.5.2 Safety rules
The responsible staff must ensure that the application or use of the products described satisfy all the
requirements for safety, including all the relevant laws, regulations and guidelines.
DANGER
Serious risk of injury through electric shock!
Due to the DC link capacitors dangerous voltage (> 890VDC) may persist at the DC link con-
tacts “ZK+ and ZK- (DC+ and DC-)“ and “RB+ and RB-“ after the servo drive has been dis-
connected from the mains supply. After disconnecting the servo drive wait at AX5101 -
AX5125 and AX520x; 5 minutes, at AX5140/AX5160/AX5172; 15 minutes, at AX5190/
AX5191; 30 minutes and at AX5192/AX5193; 45 minutes and measure the voltage at the

12.5.5 Electrical installation
12.5.5.1 Important notes
DANGER
Serious risk of injury through electric shock!
Only staff qualified and trained in electrical engineering are allowed to wire up the brake re-
sistors.
• Check the assignment of the servo drive and the brake resistor. Compare the rated
voltage and the rated current of the devices.
• Always make sure that the brake resistors are de-energized during assembly and
wiring, i.e. no voltage may be switched on for any piece of equipment which is to be
connected. Ensure that the control cabinet remains turned off (barrier, warning signs
etc.). The individual voltages will only be turned on again during commissioning.
• Due to the DC link capacitors, the DC link contacts "ZK+ and ZK- (DC+ and DC-)" and
"RB+ and RB-" may be subject to dangerous voltages exceeding 890VDC, even after the
servo drive was disconnected from the mains supply.
Wait 5 minutes for the AX5101 - AX5125 and AX520x; 15 minutes for the AX5140/
AX5160/AX5172; 30 minutes for the AX5190/AX5191; 45 minutes for the AX5192/
AX5193 after disconnecting, and measure the voltage at the DC links "ZK+ and ZK-
(DC+ and DC-)". The device is safe once the voltage has fallen below 50 V.

12.5.5.5 Short-term capacity
Brake resistors are usually not operated continuously, but only exposed to short-time duty. In the following
section the permitted short-term capacity is calculated based on the continuous power, overload factor and
duty cycle.
12.5.5.5.1 Duty cycle
The duty cycle is a relative value that depends on the switch-on time (ton) and the cycle time. Cycle times up
to 120 sec. are used directly in the calculation. Should the cycle time exceed 120 sec., the maximum
relevant cycle time of 120 sec. is used in the calculation.
Sample 1
Ton = 60 s
Cycle time = 280 s
Duty cycle = 50%
Sample 2
Ton = 40 s
Cycle time = 100 s
Duty cycle = 40 %
Note
Further information of external brake resistors:
For further information on the configuration and diagnostics of external brake resistors,
please refer to the function description of the servo drive AX5000: “Diagnostic of external
brake resistors”.
Accessories
Servo Drives AX5000 241
Version: 2.4
12.5.5.5.2 Overload factor
Calculation formula
Short-term capacity = continuous power x overload factor
12.5.5.6 Overtemperature and continuous power at 100% duty cycle
If your application requires a higher continuous power than the specified nominal capacity, you can accept
this state if a higher brake resistor temperature is permitted. The following diagram shows the
overtemperature v. the continuous power.
Normal operating range,
max. 130%
Permitted operating range,
max. 160%
Inadmissible operating range,
more than 160%
This operating range is recommended for
maximum service life and error-free opera-
tion.
This operating range is still permitted, al-
though it results in shorter service life with
higher failure probability
In this operating range there is a risk of de-
struction of the brake resistor through over-
heating. Due to the high temperatures the
adjacent components are also at risk.
Attention
Destruction of the brake resistor and adjacent components
Always ensure adequate ventilation of the brake resistor, since the temperatures of the
housing surface may exceed 200 °C.

12.9.2 Installing the mains filter
WARNING
Caution - Risk of injury through electric shock!
De-energize all electrical components (servo drive, control cabinet etc.) before commenc-
ing the installation or deinstallation of the mains filter.
WARNING
Caution - Risk of injury through electric shock!
Mains filters contain components that can store electrical charge. Wait 5 minutes after dis-
connecting the filters and measure the voltage on conductors L1 to L3. The device is safe
once the voltage has fallen below 50 V.
CAUTION
Personal injuries!
When installing the mains filter, the protective earth cables must be connected first as a
matter of principle. They must be disconnected last when deinstalling. Depending on the
size of the leakage current, the special regulations for the implementation of the protective
earth connection must be observed. Minimum requirement for the protective conductor KU-
value 1) = 4.5 for leakage currents IL < 10 mA or KU = 6 for IL > 10 mA.
1) The KU-value is a variable for the classification of safety-related types of failure for protection against
dangerous shock current and excessive heating. A value of KU = 4.5 in relation to interruption is attained:
• with a permanently attached protective conductor ≥ 1.5 mm2
• for protective conductor connection ≥ 2.5 mm2 with plug connector for industrial systems (IEC
60309−2).
KU = 6 in relation to interruption is attained with permanently connected conductors ≥ 10 mm2, wherein the
type of connection and routing must comply with the standards applicable to PEN conductors.
Attention
Destruction of the mains filter
The mains filters must be protected by means of an appropriate overcurrent protection de-
vice against the impermissible exceeding of the rated current.

13 Appendix
13.1 Error management
13.1.1 General
Fatal errors are error types requiring reinitialization of the connected AX5000 feedback systems. For this the
communication status of the EtherCAT Slave State Machine must be changed from Operational (Op) to
Safe-Operational (Safe-Op), which takes place automatically on the occurrence of a fatal error in the case of
standard parameterization. In such a case the drive is in ErrSafe-Op, since an error is additionally signaled.
Since two-channel devices possess only one communication unit and no axis operation is possible in the
SafeOp state, both channels are stopped by default. In this particular case, the change from Op to ErrSafe-
Op results in the working counter of the SyncUnit becoming invalid, since the AX5000 can no longer supply
valid actual values, resulting in all servo drives in this SyncUnit being disabled.
13.1.2 Requirement
The measures described in this section assume the following software versions.
• TwinCAT v2.10 b1329 or later versions
• Firmware v2.x or later versions
13.1.3 Parameterization
A fatal error completely stops a two-channel device by default, i.e. the error-free channel and the associated
SyncUnit are also stopped. If such a behavior is not permitted in the application, the default behavior can be
changed with the following parameterization of IDN P0-0350.
P-0-0350: Change of communication state in the event of fatal errors
0: Immediate state change (default)
If the servo drive is in "Op" state when the fatal error occurs, it immediately changes from "Op" to "ErrSafe-
Op" and sets the error bit in the EtherCAT state.
1: No change in communication state while the other channel is enabled
In this case the AX5000 initiates the state change from Op to ErrSafe-Op in the event of a fatal error on one
channel only once the error-free channel has been deactivated. The error-free channel can therefore
continue to operate until it is deactivated.
2: Change of status when the reset command is called (S-0-0099)
In the case of an active fatal error, the AX5000 only changes to "ErrSafeOp" if the Reset command is
executed in the drive; hence, the change of state can be initiated at the best possible time from the
application by means of the Reset command.
Appendix
Servo Drives AX5000262 Version: 2.4
PLC
The IDN P-0-0040 is used in order to be able to diagnose in the PLC whether a fatal error situation has
occurred that will lead to a change of status when next deactivating a channel or when calling the Reset
command. This IDN should be read acyclically in the PLC with block "FB_SoERead". Cyclic evaluation is not
meaningful, since the AX5000 no longer supplies valid inputs in ErrSafe-Op state after a fatal error, and
therefore no valid information is transferred cyclically.
Bit 0: this bit indicates whether the other channel has an error that will lead to a change of communication
from ‘Op’ to ‘ErrSafe-Op’ on deactivation of this channel.
Bit 1: this bit indicates whether this channel has a fatal error that will lead to a change of communication from
‘Op’ to ‘ErrSafe-Op’ on deactivation of the other channel. An error reset is not possible as long as this bit is
set.
Bit 2: this bit indicates whether this channel has a fatal error that will lead to a change of communication from
‘Op’ to ‘ErrSafe-Op’ on executing the Reset command.
13.1.4 SyncUnit diagnostics
The individual servo drives should be consolidated in meaningful groups, depending on the application. Each
of these groups is allocated to a SyncUnit. Since each group has its own working counter, the individual
groups can continue to operate independently in the event of fatal errors. For particularly critical applications,
each AX5000 can be allocated a separate Sync Unit. However, this step should only be implemented in
cases where it is actually required, because each further Sync Unit results in additional data traffic on the
EtherCAT strand.
Allocation of servo drives to a Sync Unit
Start the TwinCAT System Manager and left-click on
the associated EtherCAT strand (1). Select the
"EtherCAT" tab (2) and left-click on "Sync Unit
Assignment" (3). The "Sync Unit Assignment"
submenu appears. Section (4) shows the servo
drives and their allocation to the Sync Units. Servo
drives AX5203 and AX5118 belong to Sync Unit
"Cycle Process", 5206 belongs to Sync Unit
"Transport".

Version: 2.4
13.1.5 Reinitialization, troubleshooting and reset
1. Analyze and rectify the fatal error.
2. Carry out an error reset via IDN S-0-0099. To this end the blocks "FB_SoEReset" or "FB_SoERe-
set_ByDriveRef" are available in the PLC.
3. Automatic change of communication state from "ErrSafe-Op" to "Op".
4. NC axis reset. To this end the block "NC_Reset" is available in the PLC.
Re 3:
In order for the communication state to automatically
switch back to "Op", flag "Wait for WcState is OK"
must be activated on the corresponding AX5000. This
is automatically the case for new configurations. In
existing configurations it may have to be set
accordingly.
Start the TwinCAT System Manager and left-click on
the associated servo drive (1). Select the "EtherCAT"
tab (2) and left-click on "Advanced Settings...."(3).
(3). The "Advanced Settings" submenu appears.
Select the flag "Wait for WcState is OK" with the left
mouse button (4).
13.2 Firmware Update
The firmware of the AX5000 is a complex software, which is absolutely necessary for the operation of the
servo drive. The servo drives are subject to a constant process of further development and improvement
and, hence, the firmware is also under constant development, so that the latest technological innovations
can also be used.
13.2.1 Firmware version on the AX5000
The current firmware version of the AX5000 is
located in "IDN S-0-0030 - Manufacturer Version" and
can be displayed using the TCDriveManager as
follows: In the TwinCAT System Manager, mark the
servo drive (1) whose firmware version you would like
to know. Open the TCDriveManager (2) and click
"Device Info" (3). A window opens and the current
firmware version (4) appears in the "IDN S-0-0030".

This old IT concept applies more than ever today, in these times of the most complex sys-
tems with ever decreasing cycle times. Please do not perform firmware updates on a sys-
tem that is working well without a reason, unless requested to do so by Beckhoff Automa-
tion.
Note
Update only within a version number!
We recommend firmware updates only within the same version number (e.g.: V.1.05 (Build
0003) to V.1.05 (Build 0007). If you want to update from V.1.05 to V.1.06, for example, you
would need to make further adjustments in TwinCAT. In accompaniment to that, we do not
recommend performing a so-called "downgrade" to a lower version number.
CAUTION
Do not work on live equipment!
The 24 V supply (plug "X03") must be connected to the servo drive in order to be able to
perform a firmware update. Make sure that the power supply (plug "X01") is disconnected
from the servo drive, so that uncontrolled movements of the equipment cannot occur.
13.2.2.1 Update preparation
So that you can perform a firmware update, a connection must be made to the computer with TwinCAT that
controls the AX5000. It is quite usual for you not to be in the area where the equipment is operated. That is
not also necessary, because there are three different procedures for establishing a connection:
Direct accesses to the control computer
You are in the same place where the equipment is
operated and can work directly on the control
computer. In this case you can continue immediately
with the next chapter "Performing the update".
Remote access to the control computer
You are in a different place and have no direct
access to the control computer. In this case you can
also perform a firmware update on the control
computer using one of the remote connections (VPN
tunnel with remote desktop, VNC etc.) that are usual
in the IT world. Please make sure that the firewall is
configured accordingly for the remote connection and
that you have the necessary rights. After establishing
the remote connection you can continue with the next
chapter "Performing the update".
Remote access by ADS
You are in a different place and have no direct access to the control computer, or the control computer is
located in a cleanroom or the like. In this case you can also perform a firmware update via remote access by
ADS. Please read in the Online Information System how to implement remote access by ADS. Afterwards
you can continue with the chapter "Performing the update". The Online Information System is multilingual!

13.2.2.2 Performing the update
Click the button (1) in the TwinCAT System Manager
to enter the configuration mode. Confirm the query
with OK (2). After that a further window appears
which must be confirmed with Yes (Ja) (3).
Deactivate the "Free Run" with No (Nein) (4).
The system is now in "Configuration mode".
In order to perform the firmware update, you must
click the "Online" tab (6) in the "EtherCAT
Device" (5). If you want to update several devices,
you can select the respective servo drives (7)
together; in the case of one device, select only the
one servo drive. Subsequently, click with the right
mouse button inside the selected area and select the
command "Firmware Update" (8) in the command
overview.
In the place where you have stored the desired
firmware version, select the firmware file (9) and click
"Open" (10). Confirm the window that then opens with
"OK"; the firmware update is then performed. After
successful completion you must click OK (11) in the
concluding "Function Succeeded" window.
Subsequently, TwinCAT must be brought from
configuration mode back into operation mode. To do
this, click the button (12) and confirm the query that
appears with "OK" (13).
Note
Update failed!
If the firmware update is aborted with an error message, you should try again. If the abor-
tion occurs several times, please start a further attempt with another copy of the firmware
file.
