Preface

Danger and warning information
DANGER
Commissioning is absolutely prohibited until it has been completely ensured that the
machine, in which the components described here are to be installed, is in full compliance
with the provisions of the EC Machinery Directive.
Only appropriately qualified personnel may commission the SINAMICS units and the
motors.
This personnel must carefully observe the technical customer documentation associated
with this product and be knowledgeable about and carefully observe the danger and
warnings.
Operation of electrical equipment and motors inevitably involves electrical circuits with
dangerous voltages. All of the work carried out on the electrical machine or system must be
carried out while it is in a no-voltage condition.
When the machine or system is operated, hazardous axis movements can occur.
Notes regarding operation with residual current protective devices (FI, RCD) see the
"Manual" of the converter that is being used.
In combination with the drive system, the motors are generally approved for operation on
TN and TT line supply systems with grounded neutral and on IT line supply systems.
When connected to IT line supply systems, when a first fault occurs between an active part
and ground, this must be signaled using appropriate monitoring equipment. In accordance
with IEC 60364-4-41, it is recommended that the first fault is removed as quickly as is
practically possible.
In systems with a grounded external conductor, an isolating transformer with grounded
neutral (secondary side) must be connected between the line supply and the drive system
to protect the motor insulation from excessive stress.
DANGER
There is a risk of shock due to the residual voltages at the motor terminals!
When the power supply voltage is switched-off, active parts of the motor can have a charge
of more than 60 μC. In addition, at open-circuit cable ends – e.g. when a connector is
withdrawn – even after the power has been disconnected, a voltage of more than 60 V is
present for 1 s. This is the reason that you must apply the appropriate measures to provide
protection against residual voltages!

Preface

WARNING
For 1FW3 motors, voltages are present at the motor terminals when the rotor is rotating
(as a result of the permanent magnets). The voltage can be as high as 1000 V depending
on the type of motor.
The equipment and motors must be transported, stored, installed, mounted, operated,
serviced, and maintained properly in order to ensure that they function correctly and safely.
In the case of special versions of the drive units and motors, the information and data
provided in the catalogs and quotations also apply.
In addition to the danger and warning information/instructions in the technical customer
documentation supplied, the applicable domestic, local and plant-specific regulations and
requirements must be carefully taken into account.
CAUTION
The motors can have surface temperatures of over +100 °C.
For this reason, temperature-sensitive components (e.g. cables or electronic components)
must not come into contact with or be attached to the motor.
When connecting the cables, ensure that they
– are not damaged
– are not subject to tensile stress
– cannot be touched by rotating components.
CAUTION
Motors should be connected in accordance with the operating instructions. They must not
be connected directly to the three-phase supply because this will damage them.
SINAMICS units and synchronous motors are subject to a voltage test during routine
testing. While the electrical equipment of industrial machines is being subjected to a voltage
test in accordance with EN 60204-1, Section 19.4, all SINAMICS drive unit connections
must be disconnected/withdrawn in order to avoid damaging the SINAMICS drive units.
CAUTION
Motors with DRIVE-CLiQ interface have an electronic rating plate which contains motor and
encoder-specific data. This is the reason that encoder modules with DRIVE-CLiQ interface
or mounted Sensor Module may only be operated on the original motor - and may not be
mounted onto other motors or replaced by a Sensor Module from other motors.
The DRIVE-CLiQ interface has direct contact to components that can be damaged/
destroyed by electrostatic discharge (ESDS). Neither hands nor tools that could be
electrostatically charged should come into contact with the connections.

Preface

Note
When operational and in dry operating rooms, SINAMICS units with synchronous motors
fulfill the Low-Voltage Directive.
In the configurations specified in the associated EC Declaration of Conformity, SINAMICS
units with synchronous motors fulfill the EMC Directive.

ESDS instructions and electromagnetic fields
CAUTION
An electrostatic-sensitive device (ESDS) is an individual component, integrated circuit, or
module that can be damaged by electrostatic fields or discharges.
ESDS regulations for handling boards and equipment:
When handling components that can be destroyed by electrostatic discharge, it must be
ensured that personnel, the workstation and packaging are well grounded!
Personnel in ESD zones with conductive floors may only touch electronic components if
they are
– grounded through an ESDS bracelet and
– wearing ESDS shoes or ESDS shoe grounding strips.
Electronic boards may only be touched when absolutely necessary.
Electronic boards may not be brought into contact with plastics and articles of clothing
manufactured from man-made fibers.
Electronic boards may only be placed on conductive surfaces (table with ESDS surface,
conductive ESDS foam rubber, ESDS packing bag, ESDS transport containers).
Electronic boards may not be brought close to data terminals, monitors or television sets.
Minimum clearance to screens > 10 cm).
Measurements may only be carried-out on electronic boards and modules if
– the measuring instrument is grounded (e.g. via a protective conductor) or
– before making measurements with a potential-free measuring device, the measuring head
is briefly discharged (e.g. by touching an unpainted blank piece of metal on the control
cabinet).

Properties

Overview
The 1FW3 series was developed as direct drive. This direct drive is a compact drive unit
where the mechanical motor power is transferred directly to the driven machine without any
mechanical transmission elements. 1FW3 complete torque motors are water-cooled, highpole (slow running) permanent-magnet-excited synchronous motors. The operating
characteristics are comparable to those of regular synchronous motors.
The range includes 3 outer diameters with various shaft lengths. For shaft heights 150 and
200, the stator and rotor have a flange with centering edges and tapped holes at the DE that
allow them to be integrated into a machine.
The complete torque motor 1FW3 can be ordered with various shaft versions:
● Hollow shaft
● Plug-on shaft with integrated shaft centering
● Solid shaft
These allow highly flexible design and maintenance concepts to be implemented. 1FW3
torque motors can be combined with the SINAMICS S120 drive system to create a powerful,
high-performance system. The integrated encoder systems for speed and position control
can be selected according to the application.

Overview of the special Heavy Duty version
In many machining processes in the industrial environment, the tools and machining
equipment are subjected to extreme mechanical stresses. This is the case in metal forming
for example, but also in machining processes in which extremely high forces must be
applied.
Also the trend towards greater productivity and more refined products requiring the use of
more complex machining techniques demands the use of state-of-the-art but also extremely
rugged drive systems and automation technology.

Motor description
1.1 Properties
Siemens is offering, with the complete 1FW3 Heavy Duty torque motor, a direct drive that
addresses the following requirements.
The powerful, permanent-magnet synchronous motor is characterized on the one hand by its
high dynamic response and precision. On the other hand, the motor has a mechanically
rugged design, enabling it to resist shocks in the range of up to 10 g without any difficulty.
The 1FW3 Heavy Duty torque motor is ideally suited to following the motion profiles with high
demands on the dynamic performance of higher-level motion controllers even under harsh
operating conditions.
In contrast to motor/gearbox combinations, the complete 1FW3 Heavy Duty torque motor is
characterized not only by its enhanced ruggedness, but also by its compactness. These
characteristics make it particularly suitable as a main drive in servo presses.
The Heavy Duty version is defined by specifying option +L03. At the present time, only shaft

Motor Module
The rated motor current (IN) is used as a basis to dimension the appropriate Motor Modules
for the 1FW3 motors. If the full motor stall torque is required, the Motor Modules must be
dimensioned according to the motor stall current (I0).
If the motor is temporarily operated at operating points above the S1 characteristic, the
current drawn by the motors at these points must be taken into account and the appropriate
Motor Module configured.
Note
Configuration tool
The SIZER for SIEMENS Drives engineering tool supports you when dimensioning and
configuring the drive system (see the Chapter "Engineering").
The engineering tool supports you here (see Chapter "Engineering").

Procedure when engineering

Motion Control
Servo drives are optimized for motion control applications. They execute linear or rotary
movements within a defined movement cycle. All movements should be optimized in terms
of time.
As a result of these considerations, servo drives must meet the following requirements:
● High dynamic response, i.e., short rise times
● Capable of overload, i.e. a high reserve for accelerating
● Wide control range, i.e. high resolution for precise positioning

General procedure when engineering
The function description of the machine provides the basis when engineering the drive
application. The definition of the components is based on physical interdependencies and is
usually carried-out as follows:

2.2 Procedure when engineering

2.2.1

1. Clarification of the type of drive
The motor is selected on the basis of the required torque, which is defined by the application,
e.g. traveling drives, hoisting drives, test stands, centrifuges, paper and rolling mill drives,
feed drives or main spindle drives. Gear units to convert motion or to adapt the motor speed
and motor torque to the load conditions must also be considered.
As well as the load torque, which is determined by the application, the following mechanical
data are among those required to calculate the torque to be provided by the motor:
● Masses moved
● Diameter of the drive wheel/diameter
● Leadscrew pitch, gear ratios
● Frictional resistance
● Mechanical efficiency
● Traversing paths
● Maximum velocity
● Maximum acceleration and maximum deceleration
● Cycle time
You must decide whether synchronous or induction motors are to be used.
Synchronous motors are the best choice if it is important to have low envelope dimensions,
low rotor moment of inertia and therefore maximum dynamic response. These motors are
operated in control type "servo". For additional applications, the 1FW3 can also be operated
in the "Vector" control mode.
The following factors are especially important when engineering a drive application:
● The line system configuration, when using specific types of motor and/or line filters on
IT systems (non-grounded systems)
● The ambient temperatures and the installation altitude of the motors and drive
components.
The motor-specific limiting characteristics provide the basis for defining the motors.
These define the torque or power characteristic versus the speed and take into account the
motor limits based on the DC-link voltage of the power or motor module. The DC-link
voltage, in turn, is dependent on the supply voltage and, with multi-motor drives, on the type
of the line module.

Limit curves for synchronous motors

2. Definition of supplementary conditions and integration into an automation
system
You must decide whether synchronous or induction motors are to be used.
Synchronous motors are the best choice if it is important to have low envelope dimensions,
low rotor moment of inertia and therefore maximum dynamic response.
Induction motors can be used to increase maximum speeds in the field weakening range.
Induction motors for higher power ratings are also available.
You should also specify whether the drives are to be operated as single-axis drives or in a
group as multi-axis drives.
The following factors are especially important when engineering a drive application:
● The type of line supply, when using specific types of motor and/or line filters on IT line
supply systems (non-grounded systems)
● The utilization of the motor in accordance with rated values for winding temperatures of
60 K or 100 K
● The ambient temperatures and the installation altitude of the motors and drive
components.
Other supplementary conditions apply when integrating the drives into an automation
environment such as SIMATIC or SIMOTION.
For motion control and technology functions (e.g. positioning), as well as for synchronous
functions, the corresponding automation system, e.g. SIMOTION D, is used.
The drives are interfaced to the higher-level automation system via PROFIBUS.

Configuration
2.2 Procedure when engineering
The motor is selected on the basis of the load specified by the application. Different
characteristics must be used for different loads.
The following operating scenarios have been defined:
● Load duty cycles with constant on period
● Load duty cycles with varying on period
● Duty cycle, variable
The objective is to identify characteristic torque and speed operating points, which can be
used as a basis for selecting the motor depending on the load.
Once the operating scenario has been defined and specified, the maximum motor torque is
calculated. Generally, the maximum motor torque is required when accelerating. The load
torque and the torque required to accelerate the motor are added.
The maximum motor torque is then verified using the motor limiting curves.
The following criteria must be taken into account when the motor is selected:
● The dynamic limits must be observed, that is, all speed-torque points of the load must lie
below the relevant limiting curve.
● The thermal limits must be observed, that is, in the case of synchronous motors, the RMS
motor torque at the average motor speed resulting from the load duty cycle must lie
below the S1 curve (continuous duty).
● In the case of synchronous motors, note that the maximum permissible motor torque is
reduced at higher speeds as a result of the voltage limiting curve. A clearance of 10%
from the voltage limiting characteristic should also be observed to safeguard against
voltage fluctuations.

Load duty cycles with constant on period
For load duty cycles with constant on time, specific requirements are placed on the torque
characteristic as a function of the speed
e.g. M = constant, M ~ n2, M ~ n or P = constant.
These drives typically operate at a specific operating point. and are dimensioned for a base
load. The base load torque must lie on or below the S1 curve.
In the event of transient overloads (e.g. during acceleration), an overload must be taken into
account. For synchronous motors, the peak torque must lie below the voltage limiting
characteristic.

2.2 Procedure when engineering

Load duty cycles with varying on period
As well as continuous duty (S1), standard intermittent duty types (S3) are also defined for
load duty cycles with varying on periods. This involves operation that comprises a sequence
of similar load cycles, each of which comprises a time with constant load and an off period.

Figure 2-5

S1 duty (continuous operation)

S3 duty (intermittent operation without influencing starting)

The load torque must lie below the corresponding thermal limiting characteristic of the motor.
An overload must be taken into consideration for load duty cycles with varying on times.
Note
For duty cycles in the field weakening range, the SIZER for SIEMENS Drives engineering
tool must be used. The following formulas can be used for duty cycles outside the field
weakening range.

Note
A holding torque may be required when the motor is stationary. This holding torque must be
taken into consideration for Mrms. The reason could be that self-locking gearboxes are not
used.

Duty cycle, variable
A load duty cycle defines the characteristics of the motor speed and the torque with respect
to time.

Figure 2-8

Example of a load duty cycle

A load torque is specified for each time period. In addition to the load torque, the average
load moment of inertia and motor moment of inertia must be taken into account for
acceleration. It may be necessary to take into account a frictional torque that opposes the
direction of motion.
The gear ratio and gear efficiency must be taken into account when calculating the load
and/or accelerating torque to be provided by the motor.
Note
For duty cycles in the field weakening range, the SIZER for SIEMENS Drives engineering
tool must be used. The following formulas can be used for duty cycles outside the field

Selecting motors according to the load duty cycle for motor 1FW3201-☐E☐

Motor selection
By making the appropriate iterations, a motor can now be selected that precisely fulfills the
operating conditions and application
In a second step, a check is made as to whether the thermal limits are maintained. To do
this, the motor current at the base load must be calculated. When engineering a drive
according to the load duty cycle with a constant on period with overload, the overload current
based on the required overload torque must be calculated. The calculation rules for this
purpose depend on the type of motor used (synchronous motor, induction motor) and the
operating scenario (duty cycles with constant or with different switch-on duration).
Finally, the other motor features must be defined This is realized by appropriately configuring
the motor options.

Cooling
WARNING
The equipment must be safely disconnected from the supply before any installation or
service work is carried out on cooling water circuit components.
Only qualified personnel may design, install and commission the cooling circuit.

3.1.1

Cooling circuit
The electrochemical processes that take place in a cooling system must be minimized by
choosing the right materials. For this reason, mixed installations, i.e. a combination of
different materials, such as copper, brass, iron, or halogenated plastic (PVC hoses and
seals), should not be used or limited to the absolutely essential minimum.
A differentiation is made between 3 different cooling circuits:
● Closed cooling circuit
● Semi-open cooling circuit
● Open cooling circuit
Table 3- 1

Description of the various cooling circuits

Definition

Description

Closed cooling circuit

The pressure equalizing tank is closed (oxygen cannot enter the system)
and has a pressure relief valve. The cooling water is only routed in the
motors and converters as well as the components that have to be cooled.

Semi-open cooling circuit Oxygen can only enter the cooling system through the pressure
equalization tank, otherwise the same as "closed cooling circuit".
Open cooling circuit
(tower system)

The cooling water is cooled in a tower. In this case, there is intensive
oxygen contact.

Example of a semi-open cooling circuit

Equipotential bonding
All components in the cooling system (motor, heat exchanger, piping system, pump,
pressure equalization tank, etc.) must be connected to an equipotential bonding system. This
is implemented using a copper bar or finely stranded copper cable with the appropriate cable
cross-sections.
NOTICE
Under no circumstances may the cooling water pipes come into contact with live
components. There must always be an isolating clearance of > 13 mm! The pipes must be
securely mounted and checked for leaks.

We cannot accept any liability for the quality and properties/features of third-party products.

3.1.2

Engineering the cooling circuit

Pressure
The operating pressure must be set according to the flow conditions in the supply and return
lines of the cooling circuit. The required cooling water flow rate per time unit must be set
according to the technical data of the equipment and motors.
The maximum permissible pressure with respect to atmosphere in the heat sink and thus in
the cooling circuit must not exceed 0.6 MPa (6 bar) If a pump that can achieve a higher
pressure is used, suitable measures must be provided on the system side (e.g. safety valve
p ≤ 0.6 MPa, pressure control etc.) to ensure that the maximum pressure is not exceeded.
The lowest possible differential pressure between the cooling water in the supply and return
lines should be selected to allow pumps with a flat characteristic to be used.
An additional flushback filter should be used in the circuit in order to help prevent blockages
and corrosion. This allows any material deposits to be flushed out in operation.

Mechanical properties of the motors
3.1 Cooling

Pressure equalization
If various components are connected up in the cooling circuit, it may be necessary to provide
pressure equalization.
Note
Reactor elements must be fitted at the cooling water outlet of the motor or the relevant
component!

Avoiding cavitation
During uninterrupted duty, the pressure drop by a converter or motor must not exceed
0.2 MPa (2 bar). Otherwise, the high flow rate results in damage due to cavitation and/or
abrasion.

Connecting motors in series
For the following reasons, connecting motors in series can only be conditionally
recommended:
● The required flow rates of the motors must be approximately the same (< a factor of 2)
● An increase in the cooling water temperature can result in having to derate the second or
third motor if the maximum cooling water inlet temperature is exceeded.

Cooling water inlet temperature
Note
The cooling water inlet temperature must be selected so that condensation does not form on
the surface of the motor: Tcooling > Tambient - 5 K.
Cooling water temperatures which are lower than the ambient temperature tend to result in
increased water condensation. The difference between the cooling water inlet temperature
and the ambient temperature should therefore not exceed a maximum of 5 K (Kelvin).
Furthermore, the inflow of cooling water must be interrupted when the motor is idle for
prolonged periods.
The motors are designed for operation up to a cooling water inlet temperature of +30 °C, as
long as all of the specified motor data is maintained. If the cooling water inlet temperature
deviates from this, the continuous torque will change (see the table titled "Derating factors").

1) The inhibitor is not required if it ensured that the concentration of Antifrogen N is > 20%.
2) Derating is not required for an anti-freeze protection concentration < 30%.

Biocide
Closed cooling circuits with soft water are susceptible to microbes. The risk of corrosion
caused by microbes is virtually non-existent in chlorinated drinking water systems.
Antifrogen N has a biocidal effect even at the minimum required concentration of > 20 %.
No strain of bacteria can survive if >20 % Antifrogen N is added.
The suitability of a biocide depends on the type of microbe. The following types of microbes
are encountered in practice:
● Slime-forming bacteria
● Corrosive bacteria
● Iron-depositing bacteria
At least one water analysis per annum is recommended to determine the number of bacterial
colonies. Suitable biocides are available from the manufacturer Nalco for example. The
manufacturer's recommendations must be followed regarding the concentration and
compatibility with any inhibitor used.
NOTICE
Biocides and Antifrogen N must not be mixed.
There are other manufacturers of chemical additives in the market. Equivalent products from
other manufacturers may be used. The suitability must be checked by testing.

Typical applications: General machine construction.
Note
Bearings without regreasing system
For bearings without regreasing system (SH 150 and SH 200), we recommend that the
bearings are replaced after approx. 20000 operating hours for an ambient temperatures up
to a maximum of 40 °C, or after 5 years (after delivery) at the latest.
The bearing lifetime is reduced by 50 % when motors are mounted vertically. This is the
reason that we recommend that a regreasing system is used when motors are mounted
vertically.

Regreasing system (option for 1FW315x and 1FW320x, standard for 1FW328x)
If required, 1FW3 complete torque motors can be equipped with a re-lubricating device with
a lubricating nipple M8 x 1 to DIN 71412-A for the DE and NDE bearings. This increases the
bearing change interval in accordance with the table "Bearings with regreasing system" if the
regreasing intervals are maintained and the ambient temperature 40 °C is not exceeded.
Ordering options: Order code K40
The re-lubricating device cannot be retrofitted!

NOTICE
Vertical mounting position
The regreasing interval is reduced to 50% and therefore the bearing replacement interval
when motors are mounted vertically.
Re-lubricating should be carried out manually using a grease gun (not a hydraulic gun). The
grease quantities must be observed. Bearings should be re-lubricated at a low speed if it is
not dangerous for persons. The recommended re-lubricating intervals relate to normal loads:
● Operation at speeds in accordance with the rating plate data
● Precision-balanced operation
● Use of the specified roller bearing greases

Option, special grease for low speeds +V07 (for 1FW315x and 1FW320x)
Hollow shaft version:
For motors with hollow shaft, we recommend for effective speeds up to 25 rpm that the
special LGHB2 grease is ordered with option +V07.
Solid shaft version and plug-on shaft:
For motors with solid shaft and plug-shaft, in order to achieve the bearing change interval,
we recommend for effective speeds up to 500 rpm that the special LGHB2 grease is ordered
with option +V07.

Special versions
Unfavorable factors (e.g. effects of mounting/installation, speeds, special modes of operation
or high mechanical loads) may require special measures. Contact your local Siemens office,
specifying the prevailing general conditions.

3.6

Balancing process

Requirements placed on the process when balancing mounted components - especially belt pulleys
In addition to the balance quality of the motor, the vibration quality of motors with mounted
belt pulleys and coupling is essentially determined by the balance quality of the mounted
component.
If the motor and mounted component are separately balanced before they are assembled,
then the process used to balance the belt pulley or coupling must be adapted to the motor
balancing type.
For synchronous motors, a differentiation should be made between the following balancing
types:
● Half-key balancing (an "H" is stamped on the shaft face)
● Full-key balancing (an "F" is stamped on the shaft face)
● Smooth shaft end (no keyway)
The balancing type is coded in the order designation.

Permissible operating range
The permissible operating range is limited by thermal, mechanical, and electromagnetic
boundaries.

Permissible winding temperature range
The temperature rise of the motor is caused by the losses generated in the motor (currentdependent losses, no-load losses, friction losses). Utilizing the insulation system according
to temperature class 155 (F) has a limiting effect.

Torque characteristics of motor
The maximum permissible torque depends on the permissible winding overtemperature
(100 K) and, in turn, on the mode. To adhere to the temperature limits, the torque must be
reduced as the speed increases, starting from static torque M0.
The characteristics refer to continuous duty S1 (100 K).
WARNING
Continuous duty in the area above the S1 characteristic curve is not thermally permitted for
the motor.
The speed range is affected by:
● The maximum permissible speed (mechanical) nmax mech (centrifugal forces on the rotor,
bearing lifetime), or
● The maximum permissible speed on the converter nmax Inv (output frequency, voltage
strength of the converter and/or motor)

Torque limit when operating on a SINAMICS S120 with field weakening
The SINAMICS S120 converter injects a field weakening current, which means that the
motor can operate above the voltage limiting characteristic. The method used by the
converter to inject the field weakening current has a significant influence on the curve
characteristic.
The characteristics shown apply to operation on a SINAMICS S120 converter.
Field weakening operation is always active for a SINAMICS S120 converter.
The shape of the characteristics in field weakening mode depends on the position of the
voltage limiting characteristic. Therefore, an appropriate torque-speed characteristic is
assigned in the field-weakening range for each converter output voltage.

Q>USP@

Torque characteristic of a synchronous motor operating on a SINAMICS drive system
with field weakening (example characteristic)

The permissible speed range has been limited to nmax Inv.

Torque limit when operating on a SINAMICS S120 without field weakening
It is possible to deactivate the field weakening function with the SINAMICS S120 drive
system. This therefore reduces the operating range that is available.
The shape of the voltage limiting characteristic is determined by the winding version and the
magnitude of the converter output voltage.
The voltage induced in the motor winding increases as the speed increases. The difference
between the DC link voltage of the converter and the induced motor voltage can be used to
apply the current.
For converters without field weakening option, this limits the magnitude of the current that
can be impressed. This causes the torque to drop off quickly at high speeds. All operating
points that can be achieved with the motor lie to the left of the voltage limiting characteristic
that is shown in the diagram.

Technical specifications and characteristic curves

The characteristic curve is plotted for each winding version in a separate data sheet
(see Chapter "Speed-torque characteristics"). The speed-torque characteristics for different
converter output voltages are then assigned to each data sheet.
Note
The voltage limit characteristic of a motor with 600 rpm rated speed lies far above that of the
same motor type with 200 rpm. However, for the same torque, this motor requires a
significantly higher current.
For this reason, you should select the rated speed such that it does not lie too far above the
maximum speed required for the application.
The size (rating) of the converter module (output current) can be minimized in this fashion

Offset of the voltage limit characteristic
NOTICE
A offset of the voltage limiting characteristic can only used in the case of approximately
linear limiting characteristic curves. The voltage limiting characteristic can be offset only if
the condition Vmot, new > ViN is fulfilled.
The induced voltage UiN can be taken from the motor rating plate or calculated according to
the following formula: UiN = kE ∙ nN / 1000
In order to identify the limits of the motor for a converter output voltage (Umot) other than
380 V, 425 V, 460 V or 510 V, the relevant voltage limiting characteristic curve must be
shifted (offset) for the particular new output voltage (Umot, new).
The degree of offset is obtained as follows:
For an output voltage of Vmot, new, an offset is obtained along the X axis (speed) by a factor of:

Umot, new should be 290 V; in the example, the calculation is made with UMot = 425 V
It first must be checked as to whether the condition UMot, new > UiN is fulfilled.
UiN = kE ∙ nN/1000; UiN = 520 ∙ 500/1000 = 260 V → condition Umot, new > UiN is fulfilled.

Effects of temperature and parameter scatter on the characteristic
The torque-speed characteristics specified in the following chapter relate to the nominal
values at operating temperature.

Speed limits nmax Inv
The speed is limited by the mechanical limit speed nmax mech (centrifugal forces at the rotor,
bearing service life) or the electrical limit speed nmax Inv.
CAUTION
When the machine is running (with shaft operated by motor or separately driven) at speeds
higher than nmax Inv, a voltage in excess of the maximum permissible converter voltage
might be induced in the winding. This can cause irreparable damage to the converter.
Operation is not permissible above the speed nmax Inv without protective measures or other
additional measures. Siemens AG accepts no liability for any damage occurring as a result
of failing to observe the danger warning.

kE = voltage constant (see Chapter "Speed-torque characteristics").
The SINAMICS S120 drive system calculates this value automatically.
When the converter is functioning properly, the voltage that occurs at the motor terminals in
field-weakening mode can be limited by generating a voltage in phase opposition to the
induced voltage.

4.1

Torque-speed characteristic
The voltages and currents specified in the data sheets are rms values. Other rated speeds
on request.
The specified rated data refer to Vline rms = 400 V, Active Line Module, DC link voltage,
600 V DC.
Note
Operation without water cooling
Complete torque motors 1FW3 can be operated without water cooling if the torque is
appropriately reduced and the thermal losses can be adequately dissipated. The reduction
factor depends on the shaft height, length and speed and can be provided when requested.

217

Motor components
5.1 Thermal motor protection
The KTY 84 is evaluated in the converter whose closed-loop control takes into account the
temperature characteristic of the motor winding. When a fault occurs, an appropriate
message is output on the converter. When the motor temperature increases, a message
"Alarm motor overtemperature" is output; this must be externally evaluated. If this signal is
ignored, the drive converter shuts down with the appropriate fault message after a preset
time period or when the motor limiting temperature or the shutdown temperature is
exceeded.
CAUTION
The integrated temperature sensor KTY protects the complete torque motors against
overload conditions:
up to 2 • I0 and speed ≠ 0
There is no adequate protection for thermally critical load situations, e.g. a high overload at
motor standstill. This is the reason that, for example, a thermal overcurrent relay or a PTC
thermistor (optional) must be provided as additional protection.
If the maximum overload condition lasts longer than 4 s, then additional motor protection
must be provided.
The temperature sensor is designed so that the DIN/EN requirement for "protective
separation" is fulfilled.
WARNING
If the user carries-out an additional high-voltage test, then the ends of the temperature
sensor cables must be short-circuited before the test is carried-out! If the test voltage is
connected to a temperature sensor terminal, then it will be destroyed.

PTC thermistors (optional)
For special applications (e.g. when a load is applied with the motor stationary or for
extremely low speeds), the temperature of all of the three motor phases should be
additionally monitored using a PTC thermistor triplet.
Ordering options: order code A11.
Table 5- 2

Connection and evaluation of the PTC thermistor triplet

Standard

1FW315⃞ and 1FW320⃞ motors with DRIVE-CLiQ interface
and encoders (9. MLFB position) = D, F, U

The PTC thermistor must be evaluated using an
external tripping/evaluation unit (this is not included in
the scope of supply). This means that the sensor cable
is monitored for wire breakage and short-circuit by this
unit. The motor must be de-energized within 1 s when
the response temperature is exceeded.
The thermistor connections are located in the power
terminal box on the terminal block. A cable entry hole
M16 x 1.5 is provided in the terminal box to connect this
PTC thermistor.

The PTC thermistor is connected to the drive system via the
DRIVE-CLiQ cable. Evaluation of the PTC thermistor must be
activated in the SINAMICS (see references: /GH1/ SINAMICS
S120, Control Units and Additional System Components).

5.2

Encoders
CAUTION
Encoder replacement and adjustment
The encoders are adjusted in the factory for SIEMENS drive converters. Another encoder
adjustment may be required when operating the motor with a third-party converter.
If the encoder is incorrectly adjusted to the motor EMF, this can result in uncontrolled
motion.
When a belt-mounted encoder is replaced, the position of the encoder system with respect
to the motor EMF must be adjusted. Only qualified personnel may replace an encoder.
When replacing an absolute encoder it must be re-referenced.
When replacing a coaxially mounted encoder, the encoder system does not have to be
adjusted. The position with respect to the motor EMF is ensured using mechanical
components.

Encoder connection for motors with DRIVE-CLiQ interface
For motors with a DRIVE-CLiQ interface, the analog encoder signal is internally converted to
a digital signal. There is no further conversion of the encoder signal in the drive system
required. Motors with DRIVE-CLiQ interface simplify commissioning and diagnostics, as the
motor and encoder system are identified automatically.
CAUTION
The DRIVE-CLiQ encoder contains motor and encoder-specific data as well as an
electronic type plate. This is the reason that this may only be operated on the original motor
- and may not be mounted onto other motors or replaced by the DRIVE-CLiQ encoder from
other motors.
The DRIVE-CLiQ encoder interface has direct contact to components that can be
damaged/destroyed by electrostatic discharge (ESD). The precautionary ESD measures
listed in the preface should be carefully observed.

Cables
For all encoder types (incremental encoder, absolute value encoder and Resolver) the same
DRIVE-CLiQ cables can be used between the motor and converter:

Encoder connection for motors without DRIVE-CLiQ interface
For motors without an integrated DRIVE-CLiQ interface, the analog encoder signal in the
drive system is converted into a digital signal. For these motors as well as external encoders,
the encoder signals must be connected to SINAMICS S120 via Sensor Modules.

Incremental encoder sin/cos 1Vpp

Description
This encoder senses relative movements and does not supply absolute position information.
In combination with an evaluation logic, a zero point can be determined using the integrated
reference mark, which can be used to calculate the absolute position.
The encoder outputs sine and cosine signals. These can be interpolated using evaluation
logic (usually 2048x) and the direction of rotation can be determined. In the version with
DRIVE-CLiQ interface, this evaluation logic is already integrated in the encoder.

Absolute encoders

Description, multiturn absolute encoder
This encoder outputs an absolute angular position between 0° and 360° in the specified
resolution. An internal measuring gearbox enables it to differentiate between 4096 rotations.

Description, absolute value singleturn
This encoder outputs an absolute angular position between 0° and 360° in the specified
resolution. In contrast to the multi-turn absolute encoder, it has no measuring gearbox and
can therefore only supply the position value within one revolution.

Function and technical data
● Angular measuring system for the commutation
● Speed actual value sensing
● For single-turn encoders: Indirect measuring system for absolute position determination

Braking resistors (armature short-circuit braking)

5.3.1

Function description
For transistor PWM converters, when the DC link voltage values are exceeded or if the
electronics fails, then electrical braking is no longer possible. If the drive which is coasting
down, can represent a potential hazard, then the motor can be braked by short-circuiting the
armature. Armature short-circuit braking should be initiated at the latest by the limit switch in
the traversing range of the feed axis.

Configuration Manual, (PKTS), 04/2012, 6SN1197-0AD70-0BP6

231

Motor components
5.3 Braking resistors (armature short-circuit braking)
The friction of the mechanical system and the switching times of the contactors must be
taken into account when determining the distance that the feed axis takes to come to a
complete stop. In order to avoid mechanical damage, mechanical stops should be located at
the end of the absolute traversing range.
For servomotors with integrated holding brake, the holding brake can be simultaneously
applied to create an additional braking torque – however, with some delay.
CAUTION
The converter pulses must first be canceled and this actually implemented before an
armature short-circuit contactor is closed or opened. This prevents the contactor contacts
from burning and eroding and destroying the converter.
WARNING
The drive must always be operationally braked using the setpoint input. For additional
information, refer to the Converter Configuration Manual.
The optimum braking torque of the servomotor in regenerative operation can be obtained
using armature short-circuit with a matching external resistor circuit.

Rating
The ratings of the resistors must match the particular I2t load capability. The resistors can be
dimensioned so that a surface temperature of 300 °C can occur briefly (max. 500 ms). In
order to prevent the resistors from being destroyed, braking from the rated speed can occur
max. every 2 minutes. Other braking cycles must be specified when ordering the resistors.
The external moment of inertia and the intrinsic motor moment of inertia are decisive when
dimensioning these resistors.
The kinetic energy must be specified when ordering in order to determine the resistor rating.

Dimensioning of braking resistors
The correct dimensioning ensures an optimum braking time. The braking torques which are
obtained are also listed in the tables. The data apply for braking from the rated speed. If the
motor brakes from another speed, then the braking time cannot be linearly reduced.
However, longer braking times cannot occur if the speed at the start of braking is less than
the rated speed.

The data in the following table is calculated for rated values according to the data sheet. The
variance during production as well as iron saturation have not been taken into account here.
Higher currents and torques can occur than those calculated as a result of the saturation.

6.3 Signal connection

6.3

Signal connection
DRIVE-CLiQ is the preferred method for connecting the encoder systems to SINAMICS.
Motors with a DRIVE-CLiQ interface can be ordered for this purpose. Motors with a DRIVECLiQ interface can be directly connected to the associated motor module via the available
MOTION-CONNECT DRIVE-CLiQ cables. The MOTION-CONNECT DRIVE-CLiQ cable is
connected to the motor in degree of protection IP67. The DRIVE-CLiQ interface supplies
power to the motor encoder via the integrated 24 VDC supply and transfers the motor
encoder and temperature signals and the electronic type plate data, e.g. a unique identification number, rating data (voltage, current, torque) to the control unit. The MOTIONCONNECT DRIVE-CLiQ cable is used universally for connecting the various encoder types.
These motors simplify commissioning and diagnostics, as the motor and encoder type are
identified automatically.

Motors with DRIVE-CLiQ interfaces
Motors with DRIVE-CLiQ interfaces can be connected to the associated Motor Module
directly via the MOTION-CONNECT DRIVE-CLiQ cables available. This means that data are
transferred directly to the control unit.

Motors without DRIVE-CLiQ interfaces
If a motor is not equipped with a DRIVE-CLiQ interface, the speed encoder and temperature
sensor are connected via a signal connector.
Motors that are not equipped with DRIVE-CLiQ require a Cabinet-Mounted Sensor Module
(SMC) when operated with SINAMICS S120. The motor is connected to the SMC via a
signal line. The SMC is connected to the Motor Module via a MOTION-CONNECT DRIVECLiQ cable.

6.5 Connecting-up information

6.5

Connecting-up information
Pre-assembled cables offer many advantages over cables assembled by customers
themselves. In addition to being sure that they will work perfectly and the high quality, there
are also cost benefits.
Use the power and signal cables from the MOTION CONNECT family. The maximum cable
lengths should be carefully observed. Technical data of the cables, refer to Catalog, Chapter
"MOTION-CONNECT connection system".
Apply the EMC installation guideline of the converter manufacturer. For Siemens converters,
this is available under Order No. 6FC5297-⃞AD30-0AP⃞.

Cable installation
● Shielded power and signal cables must be used.
● In exceptional cases, it is possible to use twisted motor cables or three-core cables with
additional ground conductor. Only remove insulation from the cable ends so that the
insulation completely extends up to the cable lug, to the terminal, or end sleeve.
● Protruding wire ends must be avoided.
● The connecting cables should be freely arranged in the terminal box so that the protective
conductor has an overlength and the cable conductor insulation cannot be damaged.
Connecting cables should be appropriately strain relieved.
● The cable lug size must be adapted to the dimensions of the terminal board connections
and the cross section of the line supply cable.
● Take measures to ensure that connecting cables cannot rotate, are not subject to strain
and pushing force and also provide anti-kink protection. It is not permissible to subject
cables to continuous force.
● Take special care that the required minimum air clearances are actually maintained:

6.5 Connecting-up information
Note
In order to avoid disturbing effects (e.g. as a result of EMC), the signal cables must be
routed separately away from power cables.

Internal potential bonding (for 1FW315⃞ and 1FW320⃞)
The potential bonding between the grounding terminal in the box enclosure and the motor
housing is established through the terminal box retaining bolts. The contact locations below
the heads of the bolts are bare and are protected against corrosion.
The standard screws that are used to connect the terminal box cover to the terminal box are
sufficient as potential bonding between the terminal box cover and the terminal box
enclosure.

Outer protective conductor or potential bonding conductor
Note
For 1FW328⃞ and for 1FW3204-3* / 1FW3206-3* / 1FW3208-3*, there is an additional
connection point on the frame to connect an outer protective conductor or potential bonding
conductor.
(For shaft height 1FW315⃞ and 1FW320-1* this is not required.)

Connect-up the ground conductor
The grounding conductor cross-section must be compliance with the appropriate
installation/erection regulations, e.g. acc. to IEC/EN 60204-1.
For motors with a rated power > 100 kW, the ground conductor must be additionally
connected to the motor frame. A threaded hole is provided for the ground conductor at the
designated connection point. This is suitable for connecting stranded conductors with cable
lugs or straps with an appropriately terminated conductor end.
Please note the following when connecting-up:
● The connecting surface must be bare and must be protected against corrosion using a
suitable substance, e.g. using acid-free Vaseline
● Spring washer and normal washer must be located under the head of the screw
● The minimum screw-in depth and tightening torque of the clamping screw must be
maintained (refer to the Table )

After connecting-up, the following should be checked/tested
● The inside of the terminal box must be clean and free of any cable pieces
● All of the terminal screws must be tight
● The minimum air clearances must be maintained
● The cable glands must be reliably sealed
● Unused cable glands must be closed and the plugs must be tightly screwed in place
● All of the sealing surfaces must be in a perfect condition

Current-carrying capacity for power and signal cables
The current-carrying capacity of PVC/PUR-insulated copper cables is specified for routing
types B1, B2 and C under continuous operating conditions in the table with reference to an
ambient air temperature of 40 °C. For other ambient temperatures, the values must be
corrected by the factors from the "Derating factors" table.

NOTICE
The permissible clamping range must be carefully observed! The permissible surface
pressure must not be exceeded!
A stable foundation design and precise motor alignment are prerequisites for smooth,
vibration-free operation.
The following mounting notes must be carefully observed:
● Especially for high-speed motors with flange mounting, it is important that the mounting is
stiff in order to locate any resonant frequency as high as possible so that it remains
above the maximum rotational frequency.
● Thin sheets (shims) can be placed under the motor mounting feet to align the motor and
to avoid mechanically stressing the motor. The number of shims used should be kept to a
minimum.
● In order to securely mount the motors and reliably and safely transfer the drive torque,
bolts with property class 8.8 acc. to ISO 898-1 should be used.

Plug-on installation
NOTICE
Installation using the plug-on principle
When installing the motor using the plug-on principle (motor on the shaft, enclosure
supported with a torque arm), the weight of the motor results in an additional load. This
must be taken into account when designing the bearings and shaft. Information on the
motor weight is provided in the data sheets or dimension drawings.

De-coupling the stator from the machine base using a torque arm (schematic representation)

● For the plug-on mounting, the motor weight is solely supported by the shaft extension of
the driven machine. The mounting to the motor frame cannot accept any cantilever forces
and therefore does not support the motor. This must be taken into account when
dimensioning the shaft extension and the machine bearings.
● The natural bending frequency can be shifted as a result of the lower stiffness of the
mounting to the motor frame. Operation at a rotational frequency in the range of the
natural bending frequency should be avoided.

Siemens torque arm

Option T32
In Chapter "Overview of the mounting options", it was explained that it is not permissible that
the customer's machine bearings over-determine the bearing of a shaft.
One possible solution is the Siemens torque arm.
Advantage: Torque arms ensure a torsionally-rigid motor connection in a radial direction and
balance axial tolerances and misalignments.

Figure 7-4

Schematic representation of the Siemens torque arm

When designing the mounting, it must be ensured that a possible (thermal) expansion of the
shaft extension remains in a range less than 0.1 mm.
Further, before mounting, the motor should only be placed on supporting prisms. This rules
out that the mounting flange of the Siemens torque arm is subject to inadmissibly high
cantilever forces.
Note
The Siemens torque arm is available as standard for shaft height 200, and for shaft heights
150 and 280, is available on request.

Influence of the torque arm on the speed control loop
By connecting the stator through a flexible element, with respect to the machine foundation,
the stator represents an additional system that can oscillate (see Fig A), in addition to the
two mass system comprising the load and rotor (see Fig. B).

The influence of the Siemens torque arm is shown qualitatively in the following diagram. The
two-mass oscillating system comprising motor and load still dominates the system response;
however, coupling the stator through the Siemens torque arm is manifested in the form of
additional resonance effects, which must be dampened by the closed-loop control.

Shaft-side clamping element
Various mounting options using clamping elements are shown in this Chapter.
Siemens AG in cooperation with RINGSPANN GmbH has developed various clamping
system solutions to ensure secure, friction-locked connection of torque motors to cylindrical
machine shafts - with the following objectives.
● Safely and reliably transmitting the torque
● Precisely centering the torque motor on the machine shaft
● Avoid inadmissible deformation to the torque motor components
● No stress caused by different temperature changes in the torque motor and in the
machine shaft
● Simple mounting
● Simple disassembly, even after longer periods of operation
Mounting using suitable clamping elements is explained in the following.

1. Using the clamping element (possibly with centering sleeve), mount the motor at the
intended position on the shaft extension.
2. Using screws (3) clamp the tapered ring (2) onto the tapered sleeve (1). Initially tighten all
screws diagonally so that they are hand tight (5 to 8 Nm).
3. Then tighten all of the screws (3) one after the other diagonally using a torque wrench.
When doing this, the screw may only be tightened through a maximum of ¼ of a turn.
With the torque wrench set to a torque of 127 Nm, repeat this procedure until none of the
screws turns any further. Then check that the motor runs true.
4. Then check the gap between the tapered sleeve (1) and tapered ring (2) and between the
tapered sleeve (1) and the release screw (4). There must be a minimum gap of 0.1 mm
around the complete circumference. If this minimum gap does not exist, then there is the
risk that the clamping element will not fulfill its function (excessively low joint
interference).
Causes could be: for hollow shaft extensions: excessively low wall thickness or
excessively small diameter of the clamping seat.

Options to optimize the smooth running characteristics of the mounting
The true running can be checked during procedures 2 and 3. The motor can be aligned by
specifically tightening the screws (3). If the clamping screw (3) is over-proportionally
tightened, then at this position the motor is lifted off from the shaft extension.
If, after tightening to the final torque, the true running check indicates an excessively high
deviation, then all of the clamping screws (3) should be released and tightening procedures
2 and 3 should be repeated, checking the true running and specifically tightening the
clamping screws (3).

Disassembly
If, when disassembling the clamping element, after removing the clamping screws (3) the
tapered ring (2) cannot be released, then proceed as follows:
1. Release the nut (5) and turn this until it comes into contact with the head of the release
screw (4).
2. Rotate the release screws (4) in the tapered ring (2) until they are in contact with the
tapered sleeve (1).
3. Screw in the release screws (4) one after the another through ¼ of a turn until the
tapered ring is released.
If the motor cannot be released from the shaft extension, for an appropriate shaft extension
design, using the release screws, it is possible to press the tapered ring until it comes into
contact with the shaft shoulder. The motor is pressed from the shaft extension by turning the
release screws further (4).
When re-using the clamping element, the release screws must be screwed back in and
secured using the nuts (5).

7.6 Natural frequency when mounted

7.6

Natural frequency when mounted
The motor is an oscillating system with a design-dependent natural frequency, which is
higher than the specified maximum speed.
When the motor is mounted onto a machine, a new system, which is capable of vibration, is
created with modified natural frequencies. These can lie within the motor speed range.
This can result in undesirable vibrations in the mechanical drive transmission.
NOTICE
Motors must be carefully mounted on adequately stiff foundations or bedplates. Additional
elasticities of the foundation/bedplates can cause resonance effects of the natural
frequency at the operating speed and, therefore, result in inadmissibly high vibration
values.
The magnitude of the natural frequency when the motor is mounted depends on various
factors and can be influenced by the following points:
● Mechanical transmission elements (gearboxes, belts, couplings, pinions, etc.)
● Stiffness of the machine design to which the motor is mounted
● Stiffness of the motor in the area around the foot or customer flange
● Motor weight
● Machine weight and the weight of the mechanical system in the vicinity of the motor
● Damping properties of the motor and the driven machine
● Installation type/position (IM B14, IM V18/19, IM B35)
● Motor weight distribution, i.e. length, shaft height

7.7

Vibration resistance
The on-site system vibration behavior depends on factors such as the output elements,
mounting situation, alignment, installation, and external vibration and can increase the level
of vibration at the motor.
Under certain circumstances, the rotor may have to be completely balanced with the output
element.
To ensure problem-free operation and a long service life, the vibration values specified to
ISO 10816 must not be exceeded at the defined measuring points on the motor.

Braking torque Mbr rms
Mbr rms corresponds to the average braking torque for armature short-circuit braking that is
achieved through the upstream braking resistor Ropt.

Cyclic inductance LD
The cyclic inductance is the sum of the air gap inductance and leakage inductance relative to
the single-strand equivalent circuit diagram. It consists of the self-inductance of a phase and
the coupled inductance to other phases.

Maximum achievable efficiency along the S1 characteristic or below the S1 characteristic
without field weakening current.

Electrical time constant Tel
Quotient obtained from the rotating field inductance and winding resistance. Tel = LD/Rph

Maximum current Imax, RMS
This current limit is only determined by the magnetic circuit. Even if this is briefly exceeded, it
can result in an irreversible de-magnetization of the magnetic material. Specification of the
RMS value of a sinusoidal current.

Maximum permissible speed at converter nmax Inv
The maximum permissible speed during operation on a converter is nmax Inv. This is
calculated by means of the voltage induced in the motor and the voltage strength of the
converter.

Appendix
A.1 Description of terms

Maximum permissible speed (mechanical) nmax.
The maximum mechanically permissible speed is nmax mech. It is defined by the centrifugal
forces and frictional forces in the bearing.

Maximum speed nmax
The maximum permissible operating speed nmax is the lesser of the maximum mechanically
permissible speed and the maximum permissible speed at the converter.

Maximum torque Mmax
Torque that is generated at the maximum permissible current.
The maximum torque is briefly available for high-speed operations (dynamic response to
quickly changing loads).
The maximum torque is limited by the closed-loop control parameters. If the current is
increased, then the rotor will be de-magnetized.

Mechanical time constant Tmech
The mechanical time constant is obtained from the tangent at a theoretical ramp-up function
through the origin.
Tmech = 3 ∙ Rph ∙ Jmot/kT2 [s]
Jmot

=

Servomotor moment of inertia [kgm2]

Rph

=

Phase resistance of the stator winding [Ohm]

kT

=

Torque constant [Nm/A]

Moment of inertia Jmot
Moment of inertia of rotating motor parts.

NDE
Non-drive end

Number of poles 2p
Number of magnetic north and south poles on the rotor. p is the number of pole pairs.

Rated current IN
RMS motor phase current for generating the particular rated torque. Specification of the
RMS value of a sinusoidal current.

Appendix
A.1 Description of terms

Rated speed nN
The characteristic speed range for the motor is defined in the speed-torque diagram by the
rated speed.

Rated torque MN
Thermally permissible continuous torque in S1 duty at the rated motor speed.

Shaft torsional stiffness cT
This specifies the shaft torsional stiffness from the center of the rotor laminated core to the
center of the shaft end.

Static current I0
Motor phase current for generating the particular static torque. Specification of the RMS
value of a sinusoidal current.

Static torque M0
Thermal limit torque at motor standstill corresponding to a utilization according to 100 K.
At n = 0, this can be output for an unlimited length of time. M0 is always greater than the
rated torque MN.

Thermal time constant Tth
Defines the increase in the motor frame temperature when the motor load is suddenly
increased (step function) to the permissible S1 torque. The motor has reached 63% of its
final temperature after Tth.

Torque constant kT (value for a 100 K average winding temperature rise)
Quotient obtained from the static torque and static current.
Calculation:

kT = M0, 100K / I0, 100K

Note
This constant is not applicable when configuring the necessary rated and acceleration
currents (motor losses!).
The steady-state load and the frictional torques must also be included in the calculation.
