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 Autostart 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

Description

Controlling the Drive
Operation of the Drive is controlled by programming
a number of software parameters. These parameters
have default values that enable the Drive to be run
without initial programming. A diagram of the basic
structure of the control system is shown in Figure 1–1
below. (Refer to Chapter 11 List of Parameters for
details of the parameters.)

How best to use this
User Guide

This User Guide is arranged logistically: reading from
beginning to end will take you in the correct order
through the basic steps of installing the Drive and
getting it running with a motor.
To make subsequent adjustments to the parameters,
refer to Chapter 11 List of Parameters.
The Table of Contents is organised in a simple way to
help guide you quickly to the required section.

The Drive has two display panels and an eight-key
keypad which is located on the front panel of the
case. The display and keypad are used for the
following:

Mechanical Installation
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

Choose a location that is free from excessive
dust, corrosive vapours, gases and all liquids,
including condensation of atmospheric moisture.

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.

Do not locate the Drive in a classified hazardous
area, unless the Drive is installed in an approved
enclosure and the installation is certified.

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.

Mounting location

3.3

Install the Drive vertically for best flow of
cooling air.
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 overtemperature protection which trips the Drive
when the heatsink reaches 90°C (194°F).
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.

Leave a minimum clearance of 100mm (4in)
above and below the Drive when mounting it
close to other equipment.

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.

The minimum required heat conducting area is then:

Installing in a
sealed enclosure

Ae =

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.

440
5.5(50 − 25 )

(

= 3.2m 34.5 ft

)

The unobstructed heat-conducting area of the
enclosure is:

A e = 2HD + HW + DW

Calculate the minimum required surface area Ae for
the enclosure from:

Ae =

P
k(Ti − Tamb )

where:
Ae = Unobstructed heat-conducting area in m2
k = Heat Transmission coefficient of the enclosure

Tamb = Maximum external ambient temperature in °C
P = Power in Watts dissipated by all heat sources in
the enclosure

Figure 3–3

Enclosure having top, sides and
front surfaces free to dissipate
heat

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 ( /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)

Estimate two of the enclosure dimensions — the
height and depth, for instance. Calculate the
minimum width from:

A e − 2HD
H+D

Inserting H = 1.8 metres, D = 0.5 metre, obtain the
minimum width:

3. 2 − (2 × 1.8 × 0.5 )
1.8 + 0.5

= 0.6 metres approx

If possible, locate heat-generating equipment in the
lower part of the enclosure to encourage internal
convection. Otherwise, increase the height of the
enclosure or install ‘stirrer’ fans.

Ti = 50°C (122°F)
Tamb = 25°C (77°F)

Installing in a
ventilated enclosure

If a high ingress factor is not required, a ventilated
enclosure may be used. This will be smaller than a
sealed enclosure.
To calculate the minimum required volume of
ventilating air, use the following formula:

3.1 × P

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.

V = Air-flow in m3/hr

P = Power in Watts dissipated by all heat sources in
the enclosure
Ti = Maximum permissible operating temperature in

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).

Tamb = Maximum external ambient temperature in °C

Example
To calculate the ventilation requirement for one
CDE1100 Drive:
Pl = 440W
Ti = 50°C

Electrical Installation

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.

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

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.

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

4.2

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

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.

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.

This table is only a guide. Refer to local wiring
regulations for the correct size of cables.

remove the cover.

Power connections

Make the following connections using the size of
cable specified in para 4.1 Cables:
When an external braking resistor
is used, it is essential that resistor
over-temperature will cause the
supply to be tripped

Thermal-trip
relay

Fuses and AC
supply isolator

AC power to the Drive

Drive to the motor
DC bus choke to the Drive
External braking resistor to the Drive

Optional
RFI filter

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 overcurrent fault would be indicated (OIAC). In this case,
output chokes may be required. In difficult cases,
consult the supplier of the Drive.

4.5

Connect the DC bus choke to terminals L11 and L12 of
the Drive.

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 0 which is the User Menu.
Menu
This contains the basic parameters that may be read
or adjusted for simple applications.
The remaining menus are the Advanced Menus.
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 p0.13 is a duplicate of p1.04 (Keypad speed
reference).

7.2

Types of parameters

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 Status 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
Chapter 10 Security.

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

Setting

Description

Std.H

Standard-hold

FAST

Fast

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 p2.28 — Standard 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.

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.

When Standard-hold mode is used and the Standardramp 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 overvoltage.
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.)

follows:

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.

Parameter p3.01 can then be used either as an input

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.

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:

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.
The maximum RMS value of a sinusoidal output
current that should occur with the peak limit
operating is given by:

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.

√2

(This is approximately 1.5 times the maximum current
limit for the Drive).

Normal current limit

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.

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 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.

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.

See parameter p5.06.

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.

After having set the required value of maximum
current in p5.06, you may increase or decrease 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

The PI controller attempts to change the output

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.

If no slip compensation is required, set p5.07 at 0

p5.08

Since the Drive compensates for variations in DC bus
voltage, the resulting voltage from the voltage-tofrequency characteristics does not change with DC
bus voltage (ie. there is no change when the Drive is
braking).

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.

The value entered affects the following:

p5.07

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.)

Above 25% of rated frequency, a linear voltage-tofrequency 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.

11-22

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

Use the following procedure:

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.

this measurement is performed.
This measurement can be carried out with the

magnetisng current) must first be given to the

Stopping occurs in two phases, as follows:
Phase 1:
Phase 2:

Mode [1] — Inhibit mode

Decelerating to stop
Drive stopped

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].
CDE, CDLE Drive

In Modes [2 ]and [4], injection braking uses lowfrequency 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 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 Standardcontrolled 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.

The Drive always starts irrespective of the state
before AC power was removed. The STOP input
switch must be closed.

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).

Mode [2] — Power-down dependent

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.

The Drive starts only if it had been running when
AC power was removed. The STOP input switch must
be closed.

Lightly-loaded 50Hz induction motors supplied
by variable speed drives can go unstable at
frequencies between 10Hz and 30Hz. Highstability space vector modulation prevents this
instability.
At the transition to pulse-dropping (see b6.21),
instability can be caused especially on lightlyloaded 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.

When b6.21 is set at 1, p5.08 still defines the V/f
characteristic but the voltage will continue to rise

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.

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 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.

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.

motorized potentiometer is to control. If the
motorized potentiometer is to control speed, it is
suggested that one of the preset speed parameters is

one Drive to another. In both these cases, data is
transferred at a rate of 200Hz. Although the data rate is
slightly slower than that for a Mentor II Drive, the
protocol and Baud rate are identical. It is possible to
connect a CDE Drive to a Mentor II Drive for data transfer
in either direction.
Reset the Drive after selecting a different mode, in order
to make the new selection active.

For read-only parameters programmed into p11.19

Serial Communications

12.3

Message structure

Messages consist of the following:

12.1

Control characters
Serial address code
Parameter identifier
Data field
Block checksum (BCC)

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.

The message structure is shown below.

Serial address code

The following example shows how the BCC is
calculated.

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).

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:

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

0011 0000

0011 0001

0011 0010

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:

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.

Note
If the decimal value is less than 32, then 32 must be
added. The resulting code is then used to derive the
BCC.

Block checksum
Messages from host to Drive
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.

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

Change a parameter value

To find the value of a parameter, the host should send
a message that is structured as shown below.

To change a parameter, the message should contain
the relevant parameter identifier. The data field
should contain the required value.

The data field is not used. The final control character
should be: ENQ (Ctrl E)

For example, to set parameter p1.25 at −47.6Hz,
send:

Control

Data field −47.6
To set b1.10 at 1, send:

12.7

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 (PLC interface)
is used for this.

Control the Drive

Send a command
to the Drive

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.

Commands are used to:
Change the value of a parameter
Control the operation of the Drive

Send:

12.11 Other messages
from host to Drive

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.

Time can be saved by sending the control codes given
below:

The structure of reply messages is shown opposite.

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.

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

To ensure that the correct Drive answers, a valid fulllength read or write must occur before these codes
will work.

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
