Safety Information
Persons supervising and performing the electrical
installation or maintenance of a Drive and/or its external
Option Unit must be suitably qualified and competent in
these duties. They should be given the opportunity to
study and if necessary to discuss this User Guide before
work is started.
The voltages present in the Drive and external Option
Units are capable of inflicting a severe electric shock and
may be lethal. The Stop function of the Drive does not
remove dangerous voltages from the terminals of the
Drive and external Option Unit. Mains supplies should be
removed before any servicing work is performed.
The installation instructions should be adhered to. Any
questions or doubt should be referred to the supplier of
the equipment. It is the responsibility of the owner or
user to ensure that the installation of the Drive and
external Option Unit, and the way in which they are
operated and maintained complies with the requirements
of the Health and Safety at Work Act in the United
Kingdom and applicable legislation and regulations and
codes of practice in the UK or elsewhere.
The Drive software may incorporate an optional Auto-
start facility. In order to prevent the risk of injury to
personnel working on or near the motor or its driven
equipment and to prevent potential damage to
equipment, users and operators, all necessary precautions
must be taken if operating the Drive in this mode.
The Stop and Start inputs of the Drive should not be relied
upon to ensure safety of personnel. If a safety hazard
could exist from unexpected starting of the Drive, an
interlock should be installed to prevent the motor being
inadvertently started.
General Information
The manufacturer accepts no liability for any
consequences resulting from inappropriate, negligent or
incorrect installation or adjustment of the optional
operating parameters of the equipment or from
mismatching the Drive with the motor.
The contents of this User Guide are believed to be correct
at the time of printing. In the interests of a commitment
to a policy of continuous development and improvement,
the manufacturer reserves the right to change the
specification of the product or its performance, or the
contents of the User Guide, without notice.
All rights reserved. No part of this User Guide may be
reproduced or transmitted in any form or by any means,
electrical or mechanical including photocopying, recording
or by any information storage or retrieval system, without
permission in writing from the publisher.

3 Mechanical Installation
3.1 Hazardous areas
The application of variable speed drives may
invalidate the hazardous area certification (Apparatus
Group and Temperature Class) of squirrel cage
induction motors. Approval and certification should
be obtained for the complete installation of motor
and Drive.
3.2 Mounting location
1. Choose a location that is free from excessive
dust, corrosive vapours, gases and all liquids,
including condensation of atmospheric moisture.
2. If condensation is likely to occur when the Drive
is not in use, install an anti-condensation heater.
This heater must be switched off when the Drive
is in use; automatic switching is recommended.
3. Do not locate the Drive in a classified hazardous
area, unless the Drive is installed in an approved
enclosure and the installation is certified.
4. Install the Drive vertically for best flow of
cooling air.
5. Observe the requirements for ambient
temperature if the Drive is to be mounted
directly above any heat generating equipment
(such as another Drive). The Drive has over-
temperature protection which trips the Drive
when the heatsink reaches 90°C (194°F).
6. If the Drive is to be installed directly beneath
other equipment (such as another variable speed
Drive), ensure the Drive does not cause the
ambient temperature requirements of the
equipment to be exceeded.
7. Leave a minimum clearance of 100mm (4in)
above and below the Drive when mounting it
close to other equipment.
8. If the Drive is not supplied in a NEMA 1 case and
when ingress protection higher than IP00 (IEC529)
is required, install the Drive in an enclosure and
ensure its location and means of access conform
to UK or appropriate safety regulations. The
Drive can be surface mounted or through-panel
mounted in a sealed or ventilated enclosure.
3.3 Control Keypad
The Control Keypad is a plug-in unit which can be
detached from the Drive for mounting in a panel.
Holes are required in the panel for the fixing studs and
connector which project from the rear of the Control
Keypad housing. Refer to Figure 3–1.

3.4 Mounting the DC bus choke
A choke (inductor) is required for the DC bus.
For Drives in an IP00 case, the DC bus choke is installed
externally to the Drive. For Drives in a NEMA 1 case,
the DC bus choke is installed internally.

3.5 Installing in a
sealed enclosure
To maintain sufficient cooling of the Drive when it is
installed inside a sealed enclosure, heat generated by
all the equipment in the enclosure must be taken into
account and the enclosure must be of adequate size.
To calculate the minimum acceptable size of
enclosure, use the following procedure.
Calculate the minimum required surface area Ae for
the enclosure from:
(())

where:
Aee = Unobstructed heat-conducting area in m2
k = Heat Transmission coefficient of the enclosure
material in Watts/m2/°C
Ti = Maximum permissible operating temperature in

Tamb = Maximum external ambient temperature in °C
P = Power in Watts dissipated by all heat sources in
the enclosure
Example
To calculate the size of an enclosure for one CDE 1100
Drive. The following conditions are assumed:
The installation is to conform to IP54, requiring
the CDE Drive to be surface-mounted within a
sealed enclosure.
Only the top, front and two sides of the
enclosure are free to dissipate heat.
The enclosure is made of painted 2mm (3/32 inch)
sheet steel.
Maximum external ambient temperature: 25°C
(77°F).
Drive PWM frequency: 6kHz.
Insert the following values:
P = 440W (from Losses and Efficiency table)
Ti = 50°C (122°F)
Tamb = 25°C (77°F)
k = 5.5 (typical value for painted 2mm (1/16 inch)
sheet steel)

3.7 Mounting a DC braking
resistor
Refer to the manufacturer’s instructions for mounting
the DC braking resistor.
Mount the resistor as close as possible to the Drive,
but not in a position where air heated by it could
affect the Drive.
For Drives in an IP00 case, the DC braking resistor
should be installed externally to the Drive. For Drives
in a NEMA 1 case, the DC braking resistor should be
installed internally.
3.8 Motor cooling
When a motor is driven at low speed, its internal
cooling fan becomes less effective. If necessary,
provide it with additional cooling (such as forced
ventilation).
CDE, CDLE Drive 4-1
4 Electrical Installation
Warning
Electric shock risk
The voltages present in the following locations can
cause severe electric shock and may be lethal:
Supply cables
Output cables
Terminals
DC bus choke
Braking circuit
Certain parts of the Drive
If the Drive has been energized, the AC supply must be
isolated at least seven minutes before work may
continue. Refer to Safety Information on the inside
front cover.
4.1 Cables
For the following connections, use 3-core and 4-core
pvc-insulated steel-conduit covered cable with
copper conductors, laid in accordance with defined
conditions:
AC supply to the Drive
Drive to motor
DC bus choke to Drive
Drive to external braking resistor (if used)
Cable sizes must be selected for 100% of the RMS
currents.
This table is only a guide. Refer to local wiring
regulations for the correct size of cables.

* For 75°C (167°F) rated cable you may use the next size smaller.
4.2 Grounding
Ground connections must be made in accordance
with Figure 4–1. Grounding cables must have at least
50% of the current rating of the supply cables.
Use the shortest possible wiring to connect the Drive
to system ground. The system ground must be
connected firmly to a ground point that cannot be
accidentally disconnected.
The impedance of the ground circuit must conform to
the requirements of Health and Safety Regulations
that may apply.
Inspect the grounding circuit at appropriate intervals.
Use screened (conduit-covered) cable to the motor.
Connect the screen to ground at the power
connector on the Drive.
Ground connections on the power input and power
output connectors are connected together in the
Drive, enabling the following connections to be made
through the Drive:
Motor frame ground to system ground
Motor frame ground to the machine ground
The Drives are suitable for grounded-delta installation
without alteration.
4.3 Grounding terminals
The size of external grounding terminals should be
appropriate to the size of the grounding cables.

Figure 4–1 Power connections
To gain access to the connectors, remove the four
corner screws from the front cover of the Drive and
remove the cover.
Make the following connections using the size of
cable specified in para 4.1 Cables:
AC power to the Drive
Drive to the motor
DC bus choke to the Drive
External braking resistor to the Drive
The AC power should be applied through an isolator
and a fuse or circuit-breaker of the correct rating
(see Chapter 2 Data).
Unusually long cable runs between the Drive and the
motor may give rise to spurious tripping due to the
effect of cable capacitance. As a result, an over-
current fault would be indicated (OIAC). In this case,
output chokes may be required. In difficult cases,
consult the supplier of the Drive.
4.5 DC bus choke
Connect the DC bus choke to terminals L11 and L12 of
the Drive.
4.6 External braking resistor
When an external braking resistor is used, the isolator
must be equipped with an external trip input.
The Drive must be equipped with an optional IN42
Braking Card. Refer to the
IN42
Braking Card User Guide.
4.7 Control Keypad connections
When the Control Keypad is mounted remotely from
the Drive, use screened cable to connect the Control
Keypad to the Drive. (A 9-pin D-type connector is
used.) Connect the cable screen to an external
ground terminal which should be as close to the
Control Keypad as possible.
The connecting cable should have a maximum length
of 1.8m (6ft).

7 Programming Instructions
7.1 Menu structure
The Drive is programmed by entering values into
parameters. The parameters are held in menus that
group the parameters according to their functions.
The first menu is Menu 0Menu 0 which is the User MenuUser Menu.
This contains the basic parameters that may be read
or adjusted for simple applications.
The remaining menus are the Advanced MenusAdvanced Menus.
These contain all the parameters that may be read or
adjusted for advanced applications.
The parameters in Menu 0 are duplicates of certain
parameters in the advanced menus; for example,
parameter p0.13p0.13 is a duplicate of p1.04 p1.04 (Keypad speed
reference).
7.2 Types of parameters
There are two types of parameter, as follows:
Bit parameters
Bit parameters can be set in either of two logic
states and are used as on/off or change-over
switches.
Bit parameters are prefixed with the letter b
(eg. b1..11).
Variable parameters
Variable parameters can be set at a value within a
specified range. They are used to set numerical
values, or to set the positions of switches having
more than two options.
Variable parameters are prefixed with the letter
p (eg. p1..25).
Certain parameters contain character strings instead
of numerical values. The character strings are
displayed on the Control Keypad in place of values.
When these parameters are accessed and edited using
serial communications, a numerical equivalent is
displayed on the host computer. The numerical
equivalent is used for programming these parameters.
Refer to Chapter 11 Serial Communications.
These operating instructions are based on the Drive
being in StatusStatus mode. (When AC power is applied to
the Drive, the display is automatically in Status
mode.)
Note
If the behaviour of the display does not appear as
described in the operating instructions, refer to

10 Security
Security operates at two levels to prevent
unauthorized editing of parameters:
Standard Security
When locked, Standard Security prevents reading
and editing of all the parameters in the
Advanced Menus, , but allows reading and
editing of the parameters in the User Menu
(Menu 0).
A fixed code number is used to unlock Standard
Security.
User Security
User Security operates only when it has been
set-up by the user. When locked, it prevents
editing of all parameters in all the menus except

Ramp modes
The Ramp Modes parameter p2.02 controls
deceleration ramps only. The settings are as follows:
Setting
Description
0
Std.H Standard-hold
1
FAST Fast
2
Std.C Standard-controlled
Mode 0 — Standard-hold mode
In Standard-hold mode, deceleration occurs in steps.
The control causes the deceleration ramp to be
‘frozen’ when the DC bus voltage rises above the
standard ramp voltage (set in p2.28). When the
voltage drops below the Standard-ramp voltage, the
ramp again begins to fall. Although this type of
control does not usually give smooth deceleration
especially if the motor is lightly loaded, it is easy to
set up. A high voltage of AC supply could cause the
Drive to trip on over-voltage due to transients that
could be produced in the Standard-hold mode.
Mode 1 — Fast mode
The ramp falls at the programmed deceleration rate
subject only to the current limits programmed.
This mode is normally used when a braking resistor is used.
The dynamic break becomes active at a DC bus level of 780V
Mode 2 — Standard-controlled mode
The PID controller is used to modify the ramp so that
the DC bus voltage is held at the Standard-ramp
voltage (set in p2.28). This gives smoother control
than Standard-hold mode, but it may be necessary to
use an oscilloscope to set up the PI gains.
Care should be taken in choosing the Standard-ramp
voltage (using p2.28), because, if this is lower than
the nominal DC bus voltage produced by the AC
supply, the DC bus controller will accelerate the
motor up to the maximum frequency (set in p1.06) in
an attempt to reduce the DC bus voltage.
See p2.28Standard ramp voltage.
The Standard-controlled mode is useful in
applications where smooth deceleration is required,
particularly with lightly-loaded machines, or where
the AC supply voltage is high.
Caution
The D term operates in Standard-controlled
mode and under AC supply loss. Care must be
taken not to have instability in either case
due to an excessively high gain
p2.03 Acceleration ramp 1 R–W
Range 0.1 to 3276
s/100Hz
Default 5
Acceleration ramp rate is expressed as the time for
the output frequency to increase by 100Hz.
For example, a programmed ramp time of 5 seconds
causes the frequency to increase or decrease by 50Hz
in 2.5 seconds.
p2.04 Deceleration ramp 1 R–W
Range 0.1 to 3276

Deceleration ramp rate is expressed as the time for
the output frequency to decrease by 100Hz.

p2.28 Standard-ramp voltage R–W
Range 0 to 800 V Default 700 (EUR)
775 (USA)
390
(CDLE)
This parameter is used for Standard-hold and
Standard-controlled modes.
The minimum level for the Standard-ramp voltage
should be greater than the voltage produced on the
DC bus by the highest AC supply voltage (normally
RMS AC supply voltage x 2).
When Standard-hold mode is used and the Standard-
ramp voltage is set too low, the Drive will not stop.
If the Standard-ramp voltage is set too high and no
braking resistor is used, the Drive may trip on over-
voltage.
When Standard-controlled mode is used and the
voltage is set too low, the motor will accelerate to
maximum frequency. (AC supply loss uses a fixed
control voltage that is dependent on the voltage
rating of the Drive.)
p2.29 Proportional gain R–W
Range 0 to 99.99

Default 1.00
Enter a value of proportional gain for the PID
controller.
This is used to control the DC bus voltage during
Standard-ramp deceleration and loss of AC supply.
p2.30 lntegral gain R–W
Range 0 to 99.99
% of

Default 4.00
Enter a value of integral gain for the PID controller.
This is used to control the DC bus voltage during
Standard-ramp deceleration and loss of AC supply.
p2.31 Derivative gain R–W
Range 0 to 99.99
% of
max.
Default 0.00
Enter a value of Derivative gain for the PID controller.
This is used to control the DC bus voltage during
Standard-ramp deceleration and loss of AC supply.
The D term operates in Standard-controlled mode and
under AC supply loss. Care must be taken not to allow
instability in either case due to an excessively high gain.
p2.32 S-Ramp band R–W
Range 0 to p1.06p1.06
Hz
Default 0
Enter a value to define the frequency band for the
curve at each end of the S-ramp. Time taken for
acceleration or deceleration on the curve is double
that for a straight ramp.
If the ramp time changes during a change of speed,
the S-ramp does not give stepless acceleration or
deceleration. For example:
If different ramp rates are used for acceleration
and deceleration, and the Drive passes through
zero speed.
If the ramp rates are changed using the
acceleration or deceleration select bits.

Frequency slaving
When used in a frequency-slaving system, the Drive
can be set up as a Master, Slave or both. Frequency-
slaving, parameter b3.04 should be set at 0 to select
x192 frequency ratio.
When a Drive is not required to operate as a Slave, the
frequency input terminals can be used to accept a
frequency pulse train (from a plc for example), or

Enter a value for the denominator of the required

If p3.07 is changed while the Drive is running,
frequency locking between the Drives will not be
maintained, and the Slave Drive may trip on OIAC.
It is good practice to stop the Drive first.
It is recommended to keep p3.07 at the default
setting.
Refer to the example on the previous page for
correctly setting up the ratio.
b3.08 Enable quadrature input R–W
Range 0 or 1 Default 0
Set at 1 to enable encoder quadrature input.
This is not available when p3.03 or p3.05 are set at 1.
Quadrature input is not available if frequency output
is required, since the B channel encoder input shares
terminals with the frequency output.
The pulse-train frequency can be monitored by the
Drive, and the measured frequency used to derive the
frequency demand for the Drive. In either case,
parameters p3.06 and p3.07 (frequency input ratio)
must be set up to scale the input measurement so
that read-only parameter p3.01 indicates 100.0%
when maximum input frequency is demanded.
The following equations should be used to calculate
the scale factor required for different motor speeds
and encoder lines:
(RPM = maximum motor speed
N = Number of encoder lines)
Encoder with Quadrature
Counting enabled
Scale = 464 916
RPM N××
Encoder without Quadrature Counting
(no direction information)
Scale = 929 832
RPM N××
Frequency pulse-train input
Scale = 15 497
Fmax
It is recommended that parameter p3.07 is left at its
default value of 1.000 and the result of the above
calculations entered into parameter p3.06. If the
result of the calculation is very low, the difference in
top speed values becomes very coarse. If this occurs,
adjust p3.07 to finely tune the maximum measured
input frequency.
Example
A 2048 quadrature encoder is fitted to a 3000 RPM
motor
Scale =
464 916
3000 2048 007567
×× == .
Only 0.075 can be entered in parameter p3.06. This
value equates to a maximum speed of 3027 RPM.
A value for parameter p3.07 can be calculated as
follows:
p3.07 = p
Scale
306 0075
0 07567 0991
..
..====
Parameter p3.01 can then be used either as an input
to the PID software or a MD29 application program. If
parameter b3.09 is set at 1, p3.01 can be used as a
frequency reference for the Drive. In this case the
100.0% maximum in parameter p3.01 is automatically
scaled to give maximum frequency reference (p1.06)
in the Control Keypad reference parameter.
CDE, CDLE Drive
11-14
Resolution
When the frequency reference input is used to control
frequency demand (ie. slaving is not being used), the
resolution of the reference is dependent on the
maximum input frequency. It is not possible to
obtain a higher resolution than 0.03Hz or a resolution
from 0 to maximum frequency of greater than 1/4000
(or 0.025%). Subject to these limits, the resolution
may be improved with higher quadrature count rates.
Since the input pulses are counted over a gate period
of 16.132ms, the resolution can be calculated using the
following equations:
Encoder with Quadrature
Counting enabled
Resolution = 92 983 2. %

Peak limit
The peak limit prevents transient peaks in motor
current (torque-producing and magnetizing) from
exceeding a specific level.
The Drive accomodates transient peaks in current by
modifying the output voltage. This occurs only when
the output voltage is below the maximum for the
Drive.

current that should occur with the peak limit
operating is given by:
OIAC x (2000 / 2660) ÷ 2
(This is approximately 1.5 times the maximum current
limit for the Drive).
Normal current limit
The normal current limit modifies the output
frequency of the Drive in order to control the output
current level. This operates at a lower level than the
peak limit and is not as fast as the peak limit.
When the Drive is operating correctly, the normal
current limit should normally be sufficient to control
the Drive current, and the peak limit should rarely
operate.
The maximum current limit is defined in parameter
p11.35. The normal current limit controls only the
torque-producing current in the motor and not the
magnetizing current.
Rated torque-producing current
This is nominally the motor rated current × cosφ. The
Drive can deliver a torque-producing current of 1.2 or
1.5 times the rated level before the normal current
limit operates.

Defines bipolar torque demand.
In torque-control mode, the torque produced by the
motor is controlled by modification of the Drive
output frequency using the PI controller. This
controller uses the same P and I terms as the current
limits set in parameters p4.08 and p4.09.
Below rated frequency, the torque demand is
converted to torque-producing current.
Above rated frequency, the current is increased (to a
maximum of 4 times) to compensate for the
reduction of flux in the motor.
p4.06 is subject to normal current limits.
When the torque controller is used above rated
frequency, set lower gains. Lower motor flux levels
cause a larger change in torque-producing current for
a given change of frequency.
See parameter p5.06.

defined in p4.08 and p4.09.
It is possible to change between torque control and
frequency control when the Drive is running without
causing transient frequency changes.

The current limits operate when torque-producing

The PI controller attempts to change the output
frequency to reduce torque-producing current. If a
motoring load overloads the motor, it will stall. If the
motor is overloaded with a regenerative load, it will
accelerate to maximum frequency.
The ramp time will have an effect. The gains of the PI

higher gains.
Normally, only the P term is necessary for satisfactory
operation.

Symetrical current limit works in Motoring and

p4.11 will be the effective value.
After having set the required value of maximum
current in p5.06, you may increase or decrease the
percentage overload current using p4.11. The
maximum percentage that can be set is limited by the
overload current rating of the Drive. The limit applies
when motoring and regenerating.
The value of p4.11 is automatically reduced when the
value of p5.06 is increased beyond the default value.

p5.06 Motor rated current R–W
Range 0 to p11.33p11.33 A Default 11.33
Parameters p5.06 (motor rated current) and p5.13
(power factor) are used by the Drive to determine the
rated torque producing current (itorq rated) for the Drive.
When parameter p5.06 is set at a value lower than the
default rating of the Drive, the maximum current of the
Drive can be greater than 1.5 times the motor rating.
Consequently, the maximum value of current limit and
torque parameters (p4.04, p4.05, p4.06, p4.11,and
p6.04) can be increased proportionately.
For example, if a 110 Amp Drive has parameter p5.06 set
at 55 Amps, the maximum values of parameters p4.04,
p4.05, p4.11 and p6.04 can be 300% (2 × 150%). This
allows larger Drives to be used for a high starting torque.
When the value is increased beyond the default value of
p5.06, the value of p4.11 is automatically decreased.
Itorque = p5.06 x p5.13
The value entered affects the following:
Slip compensation
Dynamic V/f
Ixt detection level
Industrial and HVAC applications
Industrial applications benefit from a higher
percentage of overload current, but have a lower
nominal current. HVAC applications benefit from a
higher nominal current, but have a lower percentage
of overload current (typically 120%). The overload
current has the same value in each case.
See parameter p5.18.
p5.07 Motor rated RPM at full load R–W
Range 0 to 9999 rpm Default 0
Enter the value from the motor rating plate. This is
used by the Drive to apply correct slip compensation.
If no slip compensation is required, set p5.07 at 0
(default).
p5.08 Motor rated voltage R–W
Range 100 to 480 VRMS Default 400 (EUR)
240
(CDLE)
460 (USA)
Enter the value from the motor rating plate in order
to define the maximum output voltage of the Drive.
Parameter p5.08 must be programmed with the value
given on the motor rating plate. This informs the
Drive of the maximum voltage that should be applied to
the motor.
The Drive controls the output voltage to give a linear
voltage-to-frequency characteristic from 0Hz to the
motor rated frequency, and from 0V to the motor
rated voltage. (This characteristic can be modified
by voltage boost or stator resistance compensation.)
Since the Drive compensates for variations in DC bus
voltage, the resulting voltage from the voltage-to-
frequency characteristics does not change with DC
bus voltage (ie. there is no change when the Drive is
braking).
Note that, even with a perfect supply, it is not
possible to obtain an output voltage greater than the
supply voltage when motoring.
When the required voltage exceeds the maximum
possible output level (dependent on the supply) or
the rated voltage (set by the user), the frequency can
still be increased, but the motor enters the
constant-power or field-weakening region.
Whatever value of motor rated voltage is entered,
the Drive output will contain high frequency
switching components having peak voltage levels
related to the DC bus voltage level, not to the motor
rated voltage. Consequently, when a motor of low
voltage is used, the high-frequency switching
components at the Drive output may stress the
windings.

Above 25% of rated frequency, a linear voltage-to-
frequency characteristic normally produces sufficient
torque. Below this frequency, voltage boost may be
required in order to maintain the torque.
The voltage control mode selector is used to select
the required type of voltage boost at low
frequencies and the conditions for measuring stator
resistance.
Mode 0 — Auto boost
Auto boost automatically controls the voltage boost
with load. If the level is set too high, the motor can
become over-fluxed, and the boost can become
‘latched’ at a high level.
With high inertia loads at low speed, the Drive may
trip when decelerating the motor to a stop. This will
result in the motor coasting to a stop.
The level of boost is determined from the value in
parameter p5.11 (voltage boost) which is then
modified so that:
Auto boost = Voltage boost × itorq / itorq rated
Mode 1 — Fixed boost
Fixed boost can give high levels of current when
starting and stopping, but can result in over-fluxing of
the motor on light loads.
Mode 2 —
Vector mode with stator resistance
measurement at start
Mode 3 —
Vector mode with stator resistance
measurement at power up
Mode 4 —
Vector mode with no stator resistance
measurement
Vector mode is intended for operation with a single
motor and gives reasonable control of the motor flux
with different loads, since the voltage-to-frequency
characteristic is modified according to the load
inertia. (Closed-loop current control is not used.)
The voltage-to-frequency characteristic is based on
the following motor parameters:
Magnetizing current
Stator resistance
Good control of the magnetizing current (and hence
motor flux) extends down to:
Rated frequency ÷ 50
(ie. value of parameter p5.09 ÷ 50)
The parameters required for this mode can be derived by
the Drive during the magnetizing current measurement.
Measuring stator resistance
This measurement can be performed
automatically under the following conditions:
When AC power is connected to the Drive
(Ur_I mode)
When a START command is given to the Drive
(Ur_S mode)
The second condition (Ur_S) is recommended
because stator resistance can change with
temperature.
The measured value is stored in parameter p5.15,
along with a voltage offset related to the IGBT
voltage drops and other effects in the Drive
(p5.17).
When AC power is disconnected from the Drive, the
power factor and stator resistance are automatically
stored.
When Ur_I mode is selected, the voltage is based on
previously measured values (in Ur_I mode, the stator
resistance is not measured). The voltage offset (which is
usually quite small) is not saved when AC power is
removed, so this fine correction of the voltage applies
only when Ur_S or Ur_I modes are used.
CDE, CDLE Drive 11-23
Note
The results of the stator resistance
measurement (but not the magnetizing
current measurement) are to some extent
dependent on the switching frequency and
modulation technique being used. Good
control at low speed can be maintained only
when the switching frequency and space
vector modulation (see Menu 6) are not
changed after the stator resistance has been
measured.

Measuring the magnetizing current
Warning
The motor runs at half maximum speed while
this measurement is performed.
This measurement can be carried out with the
motor on- or off-load. If the measurement is to be
carried out on-load, a reasonable estimate of the
power factor of the motor (which relates to the
magnetisng current) must first be given to the
Drive. In most cases, the default value will be
sufficiently close to that of the motor. If it is not,
enter in parameter p5.13 the figure for the power
factor of the motor.
Use the following procedure:
1. Ensure the Drive is stopped.
2. Set p5.16 at 255.
3. Ensure that a trip is not active.
4. Apply a continuous signal to the STOP input
(Do not activate the START input).
5. Press the STOP–RESET button or apply a
momentary signal to the RESET input
(pin 4 of CON 3) to reset the Drive.
Note
The measurement should now be carried out.
If it is not carried out (eg. because the STOP
input is not active) the measurement is
cancelled. To try again, repeat the
preceeding instructions.
6. The power factor parameter p5.13 is now
updated with the value calculated during the
measurement.
Ensure the stop switch is closed.
Set 5.16 at 255 to start the test.
Reset the Drive to enter the new value of power
function in p5.13.

overload current of the Drive. To protect such motors,
the value of parameter p5.18 can be reduced to reduce
the time that the overload current is produced. The
default value of p5.18 is 60 seconds.

Stopping occurs in two phases, as follows:
Phase 1: Decelerating to stop
Phase 2: Drive stopped
The settings are as follows:
Mode [0] — Ramp mode
The Drive ramps to zero speed during the first phase,
and then waits for one second in the second phase to
ensure the motor has completely stopped before
disabling the output.
Mode [1] — Inhibit mode
The output is disabled as soon as a STOP command is
received, and the motor coasts to rest. The first phase
consists of a two-second delay before the Drive can be
restarted. There is no activity in the second phase.
Mode [2] — DC injection braking
Mode [3] — Ramp plus DC injection
braking
Mode [4] — Timed DC injection braking
In all these modes, the second phase consists of injection
of DC current for at least one second at the level entered
in parameter p6.04. This ensures the motor is
completely at rest before the Drive output is disabled.
The first phase of Mode [3] is the same as that for
Mode [0].

In Modes [2 ]and [4], injection braking uses low-
frequency current at a level programmed in parameter
p6.04 during the deceleration phase. In Mode [2]
this allows the Drive to detect when the motor has
reached a low speed, so the injection time is adjusted
automatically to suit the motor and the load. In
Mode [4], the time for decelerating to a stop must be
programmed in parameter p6.05.
In Mode [2] only, when a stop is initiated, the Drive
monitors the motor to detect when the speed reaches
5Hz so phase 2 can be initiated. If the injection
current is too low, the detection system does not
operate and the motor rotates continuously at a low
frequency.
The minimum level of current required is normally
between 70% and 80% of the rated current of the
motor.
Once stopping in Mode [2] or [4] has begun, it can be
terminated by the motor stopping, or the occurrence
of a trip. In this case, the Drive must be stopped
before it can be re-started.

The Auto-start modes define the behaviour of the
Drive when AC power is applied.
Mode [0] — Disabled
The Drive will not automatically start when AC power
is applied.
Mode [1] — Always
The Drive always starts irrespective of the state
before AC power was removed. The STOP input
switch must be closed.
Mode [2] — Power-down dependent
The Drive starts only if it had been running when
AC power was removed. The STOP input switch must
be closed.
p6.03 AC supply loss mode R–W
Range [0] to [2] Default rd.th [2]
dis [0] Disabled
Stop [1] Stop when AC supply is lost
rd.th [2] Ride-through short interruptions
The AC supply loss modes are as follows:
Mode [0] — Disabled
Loss of AC power is not detected. The Drive
continues to operate unchanged only while the DC bus
remains within specification. When the voltage is
below specification, the Drive ceases to control the
motor.
Mode [1] — Stop mode
Mode [2] — Ride-through mode
When loss of AC power is detected, the Drive
decelerates at a rate to return sufficient power from
the motor to the DC bus in order to supply the control
circuits. Since the PID loop for the Standard-
controlled ramp (see parameter p2.02) is used for
this function, adjustment of the PID gains (p2.29 to
p2.31) may be necessary for the feature to operate
correctly. In this case, the PID controller attempts to
force the DC bus voltage to 700V for the CDE models
(380V for the CDLE models) and then hold it constant
by changing the Drive output frequency.
Normally, the DC bus voltage can be held at a fixed
level with a PI controller. If the motor is heavily
loaded when AC power is lost, the frequency must be
reduced quickly to prevent the DC bus voltage from
reducing below specification.
The D term will operate for 250ms after loss of AC
power in order to improve the response. The D term
is stopped after this point, since it can make the
control loop unstable if it continues in operation.
The ramp rate is controlled by the PID controller, and
is at least as fast as the deceleration ramp for a
normal stop.
In order to help reduce the frequency quickly, slip
compensation is disabled when loss of AC power is
detected (this will have no effect if no slip
compensation has been programmed).
When AC power is restored and Stop mode is
selected, the Drive continues to decelerate until the
machine stops. When Ride-through mode is selected,
the motor accelerates to its normal running speed.

Rated frequency = p5.09 x (2 – (|itorq |/0.7itorq rated))
for |itorq| < 0.7itorq rated
(p5.09 = = Motor rated frequency)
where iitorqtorq is the value of torque-producing current
and iitorq_ratedtorq_rated is the rated level of torque-producing
current derived from p5.06 (motor rated current)
and p5.13 (power factor).
itorq_rated = p5.06 × p5.13
b6.20 Enable high-stability space
vector modulation
R–W
Range 0 or 1 Default 0
Set at 0 for normal space vector modulation.
Set at 1 for high-stability space vector modulation.
This is a special case of space vector modulation
which results in each phase being clamped to one or
other of the DC bus rails in the Drive for 1/6th of a cycle
of the fundamental output. This gives the following
advantages:
Lightly-loaded 50Hz induction motors supplied
by variable speed drives can go unstable at
frequencies between 10Hz and 30Hz. High-
stability space vector modulation prevents this
instability.
At the transition to pulse-dropping (see b6.21),
instability can be caused especially on lightly-
loaded machines. High-stability space vector
modulation reduces this effect.
High-stability space vector modulation has the
disadvantage that unwanted voltage components
result in more acoustic noise than when using other
techniques.
For normal and high-stability types of modulation,
dead-time compensation is used. This should help to
reduce instability when normal space vector
modulation is used in the 10Hz to 30Hz range.
b6.21 Enable quasi-square wave
output
R–W
Range 0 or 1 Default 0
When b6.21 is set at 1, p5.08 still defines the V/f
characteristic but the voltage will continue to rise
above the motor rated voltage. The Drive becomes
over-modulated until pulse-dropping occurs and a
square-wave is produced. The resultant harmonics
can produce high peak currents and cause high levels
of acoustic noise in the motor.
b6.22 Disable forward rotation R–W
Range 0 or 1 Default 0
Set at 1 to prevent the Drive producing forward
rotation of the motor (except when frequency
slaving).
b6.23 Disable reverse rotation R–W
Range 0 or 1 Default 0
Set at 1 to prevent the Drive producing reverse
rotation of the motor (except when frequency
slaving).
CDE, CDLE Drive
11-28
b6.24 Catch spinning motor R–W
Range 0 or 1 Default 0
Set b b6.24 at 1 to select this feature.
The Drive performs a sequence of tests to determine
the motor frequency before attempting to apply full
voltage to the motor. To limit the motor current, the
tests are carried out at a reduced voltage set in
p6.34 of the required voltage.
The Drive frequency is first set at maximum (set in
p1.06) in the direction in which the Drive last ran.
The frequency is then ramped to zero over a peroid
entered in p6.33 and compared with the motor
frequency.
If the motor frequency is not detected, the frequency
is set at maximum in the other direction and the test
is repeated. When the frequency is detected, the test
is stopped and the Drive starts at the detected
frequency and takes control of the motor.
If the motor frequency is not detected at all, the
Drive starts at 0Hz.
If the Drive is powered-down, the previous direction
of rotation is not stored, so the test begins in the
forward direction.
p6.25 Enable motorized
potentiometer zero start
R–W
Range 0 or 1 Default 0
When p6.25 is set at 1, and AC power is applied to the
Drive, the motorized potentiometer output is set at
zero.
When p6.25 is set at 0, and AC power is applied to
the Drive, the motorized potentiometer output
returns to the level that existed when AC power was
previously removed.
p6.26 Motorized potentiometer

Range 0.00 to 17.50 Default 0
Reset the Drive to make active.
Program the destination parameter that the
motorized potentiometer is to control. If the
motorized potentiometer is to control speed, it is
suggested that one of the preset speed parameters is
entered in p6.31. If the motorized potentiometer is
to trim speed, it is suggested that p1.15 (offset
parameter) is entered in p6.31.
p6.32 Motorized potentiometer

Range ±100.00 % Default
Saved at power down.
This parameter indicates the current level of the
motorized potentiometer. The value is saved when
AC power is removed from the Drive.
p6.33 Spin start ramp time R–W
Range 2.0 to 25.5
secs
Default 10
Time taken to ramp down from maximum frequency
(p1.06) to 0 Hz while the Drive attempts to
synchronize itself with a spinning motor. Change the
value for applications that require the Drive to be
caught in a shorter or longer time.
p6.34 Spinning motor scan voltage R–W
Range 0 to 100
%
Default 25
When the Drive is in normal operation, the rated
motor voltage varies with frequency. When the Drive
is attempting to synchronize itself to a spinning
motor, a percentage of this varying voltage is applied
to the motor. The value entered in parameter p6.34
determines this percentage.
If the value is too low, the motor may not be
detected during the scan. If the value is too high, the
Drive may trip on OIAC or OV.

p14.01 PID output RO
Range ±100.0 % Default
The inputs to the PID controller are automatically
scaled to the range ±100.0%. The PID controller
output is also within this range.
Although it would appear that the variables have only
10-bit resolution, internal calculations are made at a
higher resolution for greater accuracy. The displayed
values are scaled versions of the internal variables.
After the final addition to the main reference, the
output is automatically scaled again to match the
range of the destination parameter.
Gain parameters are actual units, as follows:
PID output = Pe + Ie/s + Des
where:
P, I and D are the programmed gains
e is the input error to the PID controller
s is the Laplace identifier

12 Serial Communications
12.1 Introduction
Serial communications can be used by a host
computer or PLC to perform the following:
Read and edit the values of parameters
Control the Drive
One host computer may control up to 81 Drives when
line buffers are used or 32 Drives without line buffers.
The serial communications format is RS485 which is a
differential link that ensures a high level of immunity
to noise. It also withstands high common-mode
rejection. The protocol is the following industry
standard:
ANSI x 3.28 2.5 A4
The data format is as follows:
7 data bits
1 start bit
1 stop bit
Even parity
12.2 Connecting the Drive
Two- wire or four-wire mode may be used (refer to
Figure 12–1).For best reliability use screened twisted
pair cable.
Connections for 4-wire mode
Connections for 2-wire mode

Serial address code
Each Drive on a serial communications link, must have
an individual address code. The required serial
address code should be entered in p11.23. The code
must have two digits, and the number 0 must not be
used. The first digit defines the group (1 to 9); the
second digit defines the Drive number in the group
(1 to 9).
The code for an individual Drive should be sent by the
host as in this example:
Drive address code: 2 8
Address code to be sent by host: 2 2 8 8
To address all the Drives in Group 2, the host would
need to send:
2 2 0 0
To address all Drives on the serial comms link, the
host would need to send:
0 0 0 0
Parameter identifier
To address an individual parameter, the host needs to
send a code that relates to the parameter number.
For example:
To address: p0.01
Send: 0001
Data field
Data are sent as numerical values with a negative
polarity sign and decimal point when appropriate.
The data field is of variable length, with a maximum
of seven characters including the decimal point. The
state of bit parameters is sent as numerical value 1 or
0 . For variable (p) parameters, having a series of
options defined by character strings on the display
(eg. p7.10), the first option (std.H = 0) is set by
sending 0, the second option (Fast = 1) by sending 1,
etc.
Block checksum
The block checksum character (BCC) is used to check
that each message has not been corrupted when
being sent. The BCC is a value that is calculated from
the ASCII codes of the characters in the parameter and
data fields.
The following example shows how the BCC is
calculated.
A message for parameter p1.25 contains the value
47.6. The parameter identifier is 0125 and the data
field contains 47.6.
The Binary codes (for the parameter identifier) are as
follows:
0
0011 0000
1
0011 0001
2
0011 0010
5
0011 0101
The first and second ASCII codes are compared in an
XOR function. The result is 0000 0001.
This result is compared with the third ASCII code
(0011 0010) which produces the result 0011 0011.
This number is then compared with the next ASCII
code. The process is repeated until the final digit in
the data field is reached, as shown below:
Character
Binary code XOR
0
011 0000
1
011 0001 0000 0001
2
011 0010 0011 0011
5
011 0101 0000 0110
010 1101 0010 1011
4
011 0100 0001 1111
7
011 0111 0010 1000
.
010 1110 0000 0110
6
011 0110 0011 0000
ETX
000 0011 0011 0011
3
011 0011
Note
If the decimal value is less than 32, then 32 must be
added. The resulting code is then used to derive the
BCC.
Messages from host to Drive
Messages from the host to the Drive are used to:
Interrogate the Drive for values or states of
parameters
Send a command to the Drive
CDE, CDLE Drive 12-3
12.4 Interrogate the Drive
To find the value of a parameter, the host should send
a message that is structured as shown below.
The data field is not used. The final control character
should be: ENQ (Ctrl E)
EOT 0 1 2 5 ENQ

12.5 Send a command
to the Drive
Commands are used to:
Change the value of a parameter
Control the operation of the Drive
To send a command, the message structure shown
below should be used.
Figure 12–4 Sending a command to the Drive
12.6 Change a parameter value
To change a parameter, the message should contain
the relevant parameter identifier. The data field
should contain the required value.
For example, to set parameter p1.25 at 47.6Hz,
send:
Parameter identifier 0125
Data field 47.6
To set b1.10 at 1, send:
Parameter identifier 0110
Data field 1
12.7 Control the Drive
To control the Drive using serial communications, no
input terminals should be programmed to control the
sequencing bits (b6.08 to b6.11). They should be
programmed using serial communications. It is
suggested that Sequencing mode 3 3 (PLC interface)
is used for this.
To control operation of the Drive, the message should
contain the relevant control parameter identifier.
The data field should contain the value relating to the
required control state. For example, to start the
Drive, b6.08 must be set at 1.
Send:
Parameter identifier 0608
Data field 1
To stop the Drive, send:
Parameter identifier 0608
Data field 0

12.8 Messages from Drive to host
Messages from the Drive to the host are used to:
Reply to an interrogation (send a message
containing the value of the parameter specified
by the host)
Acknowledge a command from the host
12.9 Reply to an interrogation
When the Drive is interrogated for the value of a
parameter, the Drive sends a message in reply that
contains the parameter identifier and, in the data
field, the value of the parameter.
The structure of reply messages is shown opposite.
12.10 Acknowledge a command
When a message has been sent by the host, the Drive
responds by sending an acknowledgement.
If the message was a command, the Drive sends the
reply message: ACK
If a command from the host is not understood, the
Drive sends the reply message: NAK
A message can be misunderstood because:
Transmission was corrupted
Message was incorrectly structured
Requested value was out of range
If the specified parameter number is not recognised
by the Drive, the Drive sends the reply message: EOT

Time can be saved by sending the control codes given
below:
NAK (Ctrl U) Repeat enquiry Interrogate the Drive repeatedly
for the current value of the last
specified parameter.
ACK (Ctrl F) Next parameter Interrogate the Drive for the
value of the next parameter in
the list.
BS (Ctrl H) Previous
parameter Interrogate the Drive for the
value of the previous parameter
in the list.
To ensure that the correct Drive answers, a valid full-
length read or write must occur before these codes
will work.
