Operating

Commissioning

Before working with the equipment check following points:

1.) Check that mains supply and motor cables are connected properly.

2.) Are the control lines properly connected to the right terminals ?

3.) s the frequency inverter properly grounded and assembled ?

4.) Remove installation residues, such as cable residues, in order to avoid short circuits.

5.) Are all screws and terminals tight ?

6.) Is the motor designed for the intended frequency range, in particular for the maximum
frequency ?

Factory defalut (initialisation):

All >pDRIVE< CX frequency inverters are initialised on delivery, i.e. with the default settings (default)
entered. The devices can be reset to these defaults settings at any time.

To reset the default settings, proceed as follows:

1.) Adjust parameter b084 to setting 01.

2.) Select the European configuration with parameter b085=01 (= default setting).

3.) Press the FUNC, UP and DOWN buttons at the same time.

4.) Hold these three buttons and press the STOP/Reset button to confirm.

5.) The inverter automatically starts initialisation. (The relevant country setting appears on the
display). If “d001” appears on the diplay, the procedure has finished.

Note:

If the software lock is active, a reset to factory default is not possible.

Commissioning via the built-in keypad:

The built-in control panel allows to control the frequency inverter without additional wiring of the
control terminals.

1.) Switch on the mains supply; the Power LED on the control panel lights up.

2.) Set parameter A002 to 02.

3.) The LED above the RUN button lights up.

4.) SSet parameter A001 to 00.

5.) The LED above the potentiometer lights up. Press the RUN button and turn the potentiometer.
The motor starts turning and the RUN LED lights up.

6.) Press the STOP button to stop the motor.

Check the following points after commissioning:

1.) Did the motor turn in the right direction ?

2.) Was there an error message during acceleration or deceleration ?
If the error message Overcurrent or Overvoltage appeared, increase the acceleration or
deceleration time.

3.) Were there any abnormal motor noises or vibrations ?

1.) see parameter b031

2.) If such parameters are adjusted, no start command is accepted during adjustment.
Impulse contacts and retained commands will be ignored as long as the inverter is still in setting
mode.

A003 Base frequency VIC 30...400 Hz 50 Hz

Adjustment of the base frequency. The base frequency is the frequency at which the output voltage
reaches its maximum value. Normally, the base frequency is equal to the nominal motor frequency.

A004 Maximum frequency VIC 30...400 Hz 50 Hz

Adjustment of maximum frequency. Between base frequency and maximum frequency the output
voltage is constant (field suppression).

F002 1st Acceleration ramp VC 0,01...3600 s 30 s

Setting of required acceleration time. The time is in reference with the range from 0 Hz to maximum
frequency (parameter A004).

F003 1st Deceleration ramp VC 0,01...3600 s 30 s

Setting of required deceleration time. The time is in reference with the range from 0 Hz to maximum
frequency (parameter A004).

F001 Output frequency VC 0,00...400,0 Hz -

Setting the reference value in MANUAL operation via the buttons at the keypad instead of the
potentiometer. Therefore, parameter A001 must be set to position 02.

A020 Internal pre-set speed if A001=02 VC 0,00...400,0 Hz 0,00 Hz

Entry of frequency reference value, if function A001 is set to position 02. Allows the entry of a
minimum frequency to which the inverter runs up without selecting a digital input “CF1...CF4” as
soon as a Start-command is issued.
If the PID controller is active, the adjusting range changes into 0 to 100 %.

To avoid possible resonance in the drive system, it is possible to program three jump frequency
ranges using functions A063...A068.

The jump frequency defines the frequency at which the drive should not be operated in steady-state.
The adjustable jump frequency range determines the frequency range faded out and actions
symmetrical to the jump frequency.

General

The PID controller is designed as a process controller with the variable “Frequency [Hz]”, whereby
P (kp), I (T

N) and D (Tv) can be adjusted individually. The reverence and actual value are standardi-

sed in % (range 0...100 %). For better presentation, they can be converted to the individual plant
value using A075 (e.g. flow 0...30 l/h).

The PID controller output is limited with 0 Hz (or A062) at the bottom and with the maximum
frequency A004 (or A061) at the top end. As a result, there is no reversal of the motor in the event
of negative deviation.

In order to optimize the disturbance behaviour of the controller, it is advisable to set the acceleration
and deceleration ramps as small as possible.

Operating & Mounting instructions – 8 074 143.03/03 – Page 31

Parameters

PID reference value

The reference value is selected using parameter A001. The following values can be used as
reference source:

Reference value Settings Standardization
Potentiometer built-in A001 = 00 0...100 %
Parameter value F001 A001 = 02 0...100 % x Parameter A075
Multispeeds A020...A035 0...100 % x Parameter A075
Analog input O (0...10 V) A001 = 01 0...100 % (independent from A011...A014
Analog input OI (4...20 mA) 0...100 % or A101...A104)

Actual value

One of the two analog inputs (O or OI) can be used as actual value input (selectio with A076).
The actual value registration is adjusted using the analog input function.
See parameters A011...A014 or A101...A104.
The settings of parameters A011 and A012 are changed by activating the PID controller (A071)
from Hz to % and by setting parameter A075 to process values.

Note:

By using the PID controller, the digital function “Automatic reference value (4..20 mA)” is not available!

Note:

Because of the influence of parameter A071 to the scaling of the reference and actual value, it is
important to change this parameter before changing any other!

Displays

Parameter d004 allows the display of the actual value, parameter F001 displays the reference value
on the LED. This values can be converted to process values using the display factor A075.
If parameter F001 is selected, the current PID reference value is displayed. It is not updated conti­nuously.
The actual value display (parameter d004) is updated continuously.

Operating & Mounting instructions – 8 074 143.03/03 – Page 32

A071

Selection of PID function: ON/OFF VIC 00 or 01 00

*) After setting the scale conversion (parameter A075) this parameters are adjusted and displayed in process

sizes.

**) If the PID controller is active, the reference value is set and displayed in percent or in process size

dependent on A075. By switch-over to manual controll (DIx ... 23 PID enable) the values are scaled and
also displayed in Hz.
This values are scaled with parameters A011...A014 (terminal O [V]) and A101...A104 (terminal OI [mA]).

The display parameters F001 and d004 are updated continuously !

Adjusting the difference between reference and actual value in percent, at which a signal is to be
issued. The setting can be done in a range from 0,0 to 100,0 % with a resolution of 0,1 % (bipolar).

The AVR function (Automatic Voltage Regulation) stabilises the motor voltage in case of fluctuating
intermediate circuit voltage (e.g. due to unstable mains supply or because of intermediate circuit
voltage drops or surges due to short acceleration or deceleration times) in order to maintain such a
high torque - especially during acceleration.

Automatic voltage regulation

AVR

V/f

During the delay phase (generatoric operation) the DC link voltage increases (as shown above). This
leads to an increase of the motor voltage. This higher motor voltage causes a higher braking torque.
Therefore, the AVR function for deceleration can be deactivated with function A081.

Parameters

Explanations of the functions for the digital inputs

Start/Stop via switch contacts:

When the contacts are closed, a Start command is
issued in the right direction (acceleration on
gradient), when open, a stop command is issued
(deceleration on gradient). The simultaneous
closing of Start forward and Start reverse also
issues a Stop command to the inverter.

Multispeeds (“binary” function):

The multispeeds (maximum 15) are selected via
the signals CF1...4 according to the table:

CF1 CF2 CF3 CF4 Reference value

0 0 0 0 analog value
1 0 0 0 1 (A021)
0 1 0 0 2 (A022)
1 1 0 0 3 (A023)
0 0 1 0 4 (A024)
1 0 1 0 5 (A025)
0 1 1 0 6 (A026)
1 1 1 0 7 (A027)
0 0 0 1 8 (A028)
1 0 0 1 9 (A029)
0 1 0 1 10 (A030)
1 1 0 1 11 (A031)
0 0 1 1 12 (A032)
1 0 1 1 13 (A033)
0 1 1 1 14 (A034)
1 1 1 1 15 (A035)

The number of digital inputs to be programmed
depends on the number of multispeeds actually
needed. The multispeeds are programmed in
parameter group A. The multispeeds are pure
reference values without any Start/Stop
commands.
Therefore, Parameter A001 “Method of speed
command” must be set to 01 “control terminals” !

Jog mode:

If the Jog command is activated, the inverter
accelerates the motor with the fastest possible
acceleration time to the set jog frequency A038.

Operating & Mounting instructions – 8 074 143.03/03 – Page 40

DC brake:

If this command is activated, the DC brake is
active.

Switch-over of parameters:

If this command is activated, the inverter switches
over to the 2nd set of parameters. Motor data,
minimum and maximum limits and the accelerati­on and deceleration times are switched over.
The concerned parameters are named A2xx.

Switch-over of ramps:

Two sets of acceleration and deceleration ramps
are avaliable. The signal “2nd ramp” is used to
switch between these two ramp sets. The values of
acceleration and deceleration time must be set in
parameter group A.
Contact closed: 2nd set of ramps active

Impulse lock:

If this command is activated, the inverter is locked
immediately, allowing the motor to come to stand­still freely. The function can be inverted
(parameters C011 to C015). By setting parameter
b088 to position 00, the inverter starts from 0 Hz
once the FRS signal is cancelled.
However, if parameter b88 is set to position 01,
the inverter starts with the acutal frequency fo the
motor (“interception of the motor“).

In both cases, the inverter starts after the waiting
time set with parameter b003. If the speed of the
motor is declined during this time beneath the
matching (restart) frequency set with parameter
b007, a restart happens at 0 Hz.

Parameters

External fault:

The activated command leads to immediate fault
shut-down with the error message „E12 - Ext.
fault“. Using this input, plant errors can be
integrated in the control of the frequency inverter.
The error message cn be realised using the break
or make contact (parameter C011 to C015).

Restart lock for undervoltage (USP)

This function prevents an automatic motor start
when the voltage returns after a power cut or
undervoltage. A restart is only possible after
resetting the error or by switching the Start
command on/off.

12 Ext. fault

13 USP

Notes:

 If the USP function is activated and the

power supply comes back or is
switched-on during a Start-command,
the inverter trips with E13.

 The USP function is also executed after

an undervoltage trip E09.

Bypass signal:

An activation of the command leads an holding of
the running motor after mains operaiton.

After the switch-over from bypass to inverter ope­ration, the inverter takes over the running motor
after the waiting time set with parameter b003.
If the speed of the motor has declined during this
time the matching (restart) frequency set with
parameter b007, a restart is done at 0 Hz.

Software lock:

This function allows an additional lock for
parameter changes via the terminals. Thus, it is
possible e.g. to lock the parameter editing
function via an externa key switch.
Contact open: parametrization enabled,
Contact closed: parametrization locked.

Switch-over to automatic reference value
(4..20 mA)

By closing the contact, it is possible to define the
frequency ref. value usnig a current input signal
(4...20mA). When the contact is open, the
frequency is defined via a voltage input signal
(0...10V). If the contact is closed, the frequency is
defined via the 4...20 mA analog input (terminals
OI - L). If the contact is open, the analog signal

0...10 V (terminals O - L) is conductive. If no
digital input is parametrized for this function, the
two reference values are added (f-correction).

Parameters

External reset:

Allows you to confirm an error via the terminals.
During operation, an external Reset-command
stops the inverter!! The signal must not be inverted
and must not be issued for more than 4 seconds.
A permanent reset is not possible. If the inverter is
running without problems, it runs to 0 Hz when an
RS signal is issued! In plants, where a common
reset signal is used for all devices, parameter
C102 must be set to position 02 !

Start/Stop via impulses:

An impulse contact (N.O.) leads a Start-command.
An impulse contact (N.C.) leads a Stop-command.
Closing the contact leads to a change of direction.
Contact open = Forward

PID controller:

If the PID controller is activated (A071=1), the
command “PID enable” disables the PID
controller and the PID ref. value acts directly on
the output frequency.

Motorpotentiometer:

Reference values via the motorpotentiometer are
defined via the signals “Motorpot increase” and
“Motorpot decrease”.
Thereby, the reference value is increased and
decreased with the adjusted acceleration/
deceleration time (F002/F003 and F202/F203) as
long as the command is active.
The motorpotentiometer is activated via parameter
A001 = 02.
The command “Motorpot reset” deletes the
reference value, if he is stored with parameter
C101 = 01.

Local control:

By closing this contact, the control via the keypad
is activated. After pressing the RUN key, the
inverter accellerates up to the reference value set
with F001 - independent from A002 “Method of
run command”.
If the contact is closed during operation, the drive
stops first.

Multispeeds (“bit”-function):

The multispeeds (maximum 7) are selected using
the signals SF1...SF7 according to the table:

SF1 SF2 SF3 SF4 SF5 SF6 SF7 Ref. value

0000000analog value
1xxxxxx 1 (A021)
01xxxxx 2 (A022)

00001x x 5 (A025)
000001x 6 (A026)
0000001 7 (A027)

If several multispeeds are selected at one time, the
lower value has priority.
The number of multispeeds depends on the actual
number of digital inputs. Maximum 5 free
adjustable digital inputs are available at a
standard control terminal.

The multispeeds are programmed in parameter
group A. The multispeeds are pure reference
values without any Start/Stop commands.

Switch-over of overload restriction:

With this command a switch-over between the two
different overload restrictions (b021...b023 and
b024...b026) is possible .

This command has no effect !

Notes:

 You can not use the same value for parameters C001 to C005.
 If a parameter is to be shifted to another terminal, the “from” terminal must be set first,

then the old value set for the “to” terminal.

Parameters

In the event of a low-voltage trip during operation, e.g. mains failure, the inverter switches to
impulse lock. If the voltage returns within the time set with b002, the inverter can be started again.
Otherwise, the unit shuts down with the message undervoltage.
If parameter b001 is set to 01, the time period b003 can be set after which the frequency inverter
tries to start-up again (after return of power). Of course, this will only happen if the power returns
within the set time.

Special safety instructions

Short mains failure

During a mains failure, the >pDRIVE< CX profi frequency inverter continues operating until the
intermediate circuit voltage drops below the minimum working level (approx. 20 % below the lowest
supply voltage). The time depends on the mains voltage before switching off, and on the load.
If a Start command is issued, the motor runs up again as soon as the power supply returns. This can
be blocked with the function "USP". If a digital input is parametrised for the function 13 USP "Restart
lock" and this signal is also issued, an error message (E13) is issued whenever the mains supply is
switched on, if a Start command has already been issued. (See description of parameters C001 to
C005)

Automatic restart

y After low mains voltage:

If a Start command is issued, there is an automatic restart every time the mains supply returns.

y After confirming an error
y After autoreset (parameter b001)

Frequencies > 60 Hz

When operating motors with frequencies over 60 Hz, the suitability of the corresponding components
must be checked first. An inquiry with the motor or machine manufacturer is important. 4-8 pole
motors are usually suitable for operation up to 100 Hz.

Insulation tests

All >pDRIVE< CX frequency inverters are tested for voltage stability and insulating resistance in
accordance with EN 50178. Insulating resistance measurements, e.g. within the scope of an
inspection, must be carried out between the short-circuited power terminals and earth only. For a
correct, complete insulation test, the CE filters must be disconnected.
Do not carry out any insulation resistance tests with the control terminals !!

Installation rules for compliance with CE regulations

The >pDRIVE< CX profi frequency inverters together with the available filter options CE-DR comply
with the EMV directive 89/336/EEC and the low-voltage directive 73/23/EEC, i.e. conformity with
EN 61800-3 and EN 50178

• Use of the option "CE-DR Filter" or use of an equivalent filter solution

• Assembly on a properly grounded metal assembly plate with good HF connection between the

motor cable screen and filter.

• Use and proper connection (bipolar !!) of screened motor cables

• Use of an AMF (Output Motor Filter) for greater motor cable lengths

• Use and proper connection of screened control cables

• Grounding the frequency inverter with at least 10 mm

Remarks on power supply

Mains impedance

Virtually all frequency inverters produce harmonic oscillation when connected to the mains, which
can interfere with other devices due to the voltage distortions thus caused.
Please note that all converters with connected intermediate circuit voltage (diode rectifier at input)
are a load on the mains supply in their total output. The use of a line choke (integrated in the CE­DR filter) is therefore highly recommended, even when using an industrial supply network.
It is absolutely necessary if: • the mains symmetry can be >3%

• the output of the upstream transformer is ≥ 500 kVA

• there are strong mains voltage drops

• the inverter is operated on a generator

• the inverter is used in residential areas

• several inverters connected via a short bus bar

are supplied by the mains network

Without a line choke, the above operating conditions can cause damage to the inverter!!

Safety remarks / FI safety switch

Frequency inverters, particularly those with CE filters (RFI filters) and screened motor cables, conduct
an increased leakage current to earth. This depends on:

• the length of the motor cable

• the type of installation and whether the motor cable is screened or not

• the set clock frequency

• the use of a radio interference suppression filters (yes or no)

• the grounding of the motor on location (grounded or not)

Especially at the moment of switching on the filter's capacitors and during operation, the earth capa­cities can lead to an unwanted FI safety switch trip. On the other hand, it is possible to block this trip
function through mains rectification at the input of the inverter with d.c. components.
Therefore, please note the following:

• Use only short-time delayed and clock-sensitive FI safety switches with considerably higher rated
trip current.

• Protect other consumers with a separate FI safety switch.

• FI safety switches upstream from a inverter are not an absolute safeguard against direct

contact!! Therefore, they should always be used in conjunction with other protective measures.

• The >pDRIVE< CX frequency inverters do not have a current-limiting effect (with fault currents),
and thus do not violate the grounding conditions.

In plants with cables of medium length, the leakage current can easily be greater than 300 mA,
depending on the conditions!!

ey to table:

1. The cable diameter indicated in the table are an index for laying the cable in air at max. 40°C,
based on the ÖVN EN 1 and VDE 0100 regulations.

For other ambient conditions and different regulations, the cable diameters must be
adjusted accordingly.

2. Pre-fuses calculated for DOL starting with bypass circuit.

3. The motor cables are designed for the maximum continuous current at an ambient temperature
of 40°C and laid in air. When a bypass circuit is used, the motor cable must be designed for the
value of the pre- or condiut fuses!
The use of NYCY or NYCWY cables for the motor cables (power cables with concentric protection
core) is a low-price alternative to screended cables.

4. In case of a trip, sf fuses protect the inverter from secondary damage in the rectifier, the charging
circuit etc.
The mains fuses represent a secondary protection of the inverter in the case of failure of the
electronic protection. However, if this fuses are blown, a primary defect has already occurred
inside the unit. Therefore, changing

the blown fuses and switching the inverter on again is not
effective. Furthermore, it is not advantageous to use circuit breakers. This has the disadvantage of
a slower switch-off.

5. If the inverter is used without

line choke (CE-DR filter) the fuses must be selected one type higher

to protect the inverter.

Operating & Mounting instructions – 8 074 143.03/03 – Page 72

Remarks to the inverter output side

Motor cable lengths

The distances between inverter and motor indicated in the table in the chapter "CE-DR Options" must
be complied with. Too long motor cables can damage the inverters!

Option: AMF (output motor filter)

To reduce the voltage rate of rise on the inverter output and the effects on parallel lines thus possi­ble, it is of advantage to use the AMF.
With long motor cables, the AMF protects the inverter and motor, and is absolutely imperative. See
table "Allocation Inverter Options Motor Cable Motor".
Especially with multimotor drives and the respective parallel motor cables, non-compliance with the
cable lengths can lead to destruction of the inverter.

Compensation capacitors

Compensation capacitors, mains filters and overvoltage protection equipment must never be
connected to the output of the inverters !!!

Switching at the inverter’s output

Operational switching between the inverter and the motor is not permissible. This would cause stress
load on the power semiconductor, and possible safety shut-down of the inverter !! This would shorten
the inverter's life !!!

Exception: A revision switch that is only used in very rare cases. Here, too, the CX should be

locked first, if possible (digital input programmed to 11 FRS "Impulse lock - idle").

Change of direction

Reversal protection switches for change in direction must not be used (see "Switching at the inverter's
output"). In order to change the direction of rotation, a digital input on the control terminal strip or a
parameter for direction selection (parameter F004) is provided.

Note:

Too long motor cables may damage the inverter.

Operating & Mounting instructions – 8 074 143.03/03 – Page 73

Mounting

General Mounting Information

Make sure, that the input voltage is 3 AC 380...480 V ±10 %, 50/60 Hz ±5 %. Ambient factors
such as high temperatures, high humidity, dust, dirt and aggressive gases must be avoided. The
inverter should be installed in a well ventilated place that is protected against direct sunlight. Install
the inverter on a fire-proof, vertical wall that does not transmit vibrations.

Warning! Do not apply mains power to the output terminals U, V, W.

Issue the operating signals START/STOP via the control terminals or the control panel, not by
switching the mains or the motor contactor. Do not install capacitors or surge absorbers in the motor
wires.

Distances from other devices or against the wall

Because of thermal convection, the frequency inverters >pDRIVE< CX are designed for vertical wall
assembly. Especially when installing the inverter in a niche, you must comply with the specified mini­mum distance from side wall or other equipment. Objects that penetrate the interior of the inverter
can cause damage.

The permissible temperature range ( -10°C to +40°C, +50°C with 2 kHz clock frequency) must not
be undercut or exceeded. The higher the ambient temperature, the shorter the lifetime of the inverter.

Do not install the inverter near heat-radiating equipment.

When installing the inverter in a cubicle, please note the size and heat elimination capacity of the
cubicle. Provide ventilation, if necessary.

2.) Control, mains supply and motor discharge should be separated, if possible

3.) Never install control lines, mains wires or motor cable in a common cable conduit!!
If control lines have

to cross power
cables, they should
do so at right
angles.

4.) Use only screened control lines (exception: relay contacts and digital inputs, if installed

completely separate from the power cables). The screen must always be grounded bilaterally
(exception: in case of earth circuit problems due to transient currents that heat the screen, only
the signal input side is grounded or a parallel compensating wire is installed).

Control lines
should be
separated from
motor cables by
a distance of at
least 30 cm.

5.) The primary function of the motor cable screen is to improve the connection between motor and

inverter, so that as little interfering current as possible flows past the filter to the mains earth.
Therefore, a screened 4-pole motor cable must be used and the screen must be connected
at both ends in accordance with the valid HF rules. The screening material (copper or steel) is less
important than good at both ends connection.

General connecting information:

1.) Power wiring with individual wires should always be

installed close to the corresponding PE conductor.

Wiring examples

Manual operation via the built-in keypad

Following parameters have to be changed:

A001= 00 Reference value via potentiometer on the keypad
A002= 02 Control commands via RUN/STOP buttons
F002= 10 s Adjust acceleration time
F003= 10 s Adjust deceleration time
A004= 50 Hz Increase max. frequency
A041= 01 Automatic torque boost

Wiring of the terminals is not necessary!!

After setting the parameters above, the frequency inverter can be started by pressing the RUN button,
the green LED above is already on. Only the frequency ref. value can be defined using the
potentiometer integrated in the control panel As soon as the RUN button is pressed, the green RUN
LED to the left of the display lights up, that means that a start command is issued. The STOP button
stops the motor or confirms an error. Alternatively, the speed definition with parameter F001 is
possible using the UP and DOWN buttons (saved in case of mains-off). Thereby, A001 must be set
to 02.

Start/Stop is realised via the digital inputs FW and 5. If both terminals are closed at the same time, a
Stop command is issued to the frequency inverter.
The required frequency can be set by turning the external potentiometer.
In addition, a test device to display the actual frequency value was also built into this example on the
analog output AM. If parameter C028 is set to 01, the motor current is displayed on the test device.
The output signal can be adjusted using parameter b080.

After setting the parameters, the inverter can be started with clockwise rotation field using terminal
FW or with anti-clockwise rotation field using terminal 5. If both terminals are closed at the same
time, a Stop command is issued to the frequency inverter.
If one of the multispeed inputs is activated, the actual ref. value is overruled and the frequency
inverter is accelerated or the motor is slowed down to the new reference setting. If no digital input is
selected, the speed can be defined using the analog inputs.
For the combination of the individual multispeeds, please see the description of parameters F001
and A020 to A035.
The wiring example also includes the parametrization of the relay outputs for terminal 11 and 12 for

Operation via integrated PID controller

Setting example: flow control

A flow rate control should be set up with the internal PID controller of the >pDRIVE< CX .

The reference value can be set via voltage input: 0...10 V = 0...300 l/h
The actual value is recorded by a data recorder 0...500 l/h = 4...20 mA.
In the event of PID deviations greater than 20 %, a warning signal must be generated.
The minimum frequency of 10 Hz must not be undercut.
The reference and actual values for the controller must be displayed in process sizes:
300 l/h =100 % control size

Control diagram

*) For the proper setting of the reference value, A075 = 3,00 is selected. Thus, 100 % PID ref.

value is represented as 300 l/h flow rate.

Ref. value needed: 0...100 % correspond to 0...300 l/h
Data recorder: 4...20 mA correspond to 0...500 l/h
Setting A102: 4...13,6 mA = 0...300 l/h = 0...100% intern

20 mA = 500 l/h = 166,6% intern → A102 = 166,6 %

Scale conversion A075: 3,0 (100% x 3,0 = 300 l/h)

Operating & Mounting instructions – 8 074 143.03/03 – Page 88

Reference value: Actual value:

Remark:

In order to ensure a correct control process within the whole PID range, the feedback value
must be able to exceed the reference value.
(A deviation is absolutely necessary in order to achieve a control action !)

To adjust the acutal value input (0...500 l/h) to the reference value input (0...300 l/h), it is necessary
to synchronize the actual value at the current input with parameter A101...A104.
Therefore, parameter A102 must be set to 500 l/h (166,6 %), so that an actual value of 300 l/h
corresponds with an reference value of 100 %.

Parameter adjustments:

A001 = 01 Reference value via control terminals

A062 = 10 Hz Minimum frequency

After setting parameter A062 to 10 Hz, the frequency inverters displays the alarm message
W025. The PRG-LED starts flashing until the inverter is started. The alarm means, that the ref.
value is lower than the minimum frequency.

Operating & Mounting instructions – 8 074 143.03/03 – Page 89

Connection

After setting the parameters, the inverter can be started with clockwise rotation field unsing terminal FW.

The example for defining the ref. value via the analog voltage input is only one configuration
example. It is also possible to define the reference value using the built-in potentiometer, using
parameter F001, with the UP and DOWN buttons or using the 2nd analog input.

RFI-filters CE-DR

All devices and equipment in electric power engineering can cause electromagnetic interference and
be disturbed by electromagnetic interference. Therefore, they are subject to the provisions of the

EMV directive 89/336/EEC

since 1.1.1996.

However, frequency inverters cannot be regarded as machines with at least one mechanically
moving component. Therefore, the Machine Directive 89/392/EEC

does not apply.

The frequency inverters >pDRIVE< CX have a CE mark on the rating plate. However, in order to
reach the relevant limits, it is necessary to comply with the installation instructions.

Installation rules:

• Use of the option "CE-DR Filter" or use of an equivalent filter solution

• Assembly on a properly grounded metal assembly plate.

• Use and proper connection (at both ends !!) of screened motor cables

• Reduce clock frequency to ≤ 5 kHz

• Use and proper connection of screened control cables

• Grounding the frequency inverter with at least 10 mm

2

for personal safety

• Separate installation of motor cables and other cables, especially control wires

Important remarks:

Motor cable lengths

The specifications regarding the permissible distance between the inverter and the motor must be
complied with. Too long motor cables can damage the inverter!

Protective measure FI safety switch

Radio interference suppression filters contain conduction capacitors to earth, i.e. the leakage current
of the entire drive is increased and there is a short charging current when the inverter is switched on.
REMEDY:

Use FI safety switches with short-time delay and higher trigger level.

WARNING:

FI safety switches do not provide absolute protection against direct contact!! Therefore,
they should always be used in conjunction with other protective measures.

Line choke (built-in into the CE-DR RFI-filter)

The CE-DR filters contain a line choke. Therefore, an additional external choke is not required.
The line choke is used to reduce the harmonic oscillation caused by the intermediate circuit and the
commutation drops caused by the rectifier.

• Voltage fluctuation ≤ ±10 %

• Voltage unbalance ≤ ±3 %

• Frequency variations ≤ ±5 %

• Voltage distortion (THD) ≤ 10 %

2.) Wiring

• For complying with the EMC-directive screened motor cables are required.

• For getting higher lengths of motor cable, it is necessary to connect an output motor filter

AMF to the output of the inverter, to reduce the stress of the inverter and the line filter caused
by the higher earth leakage currents.

• Seperate main circuit wiring from control circuit wiring.

Output-Motor-Filter AMF

Modern frequency inverters are using IGBT power modules, by which it is possible to build compact
and cheap units.

Because of the higher switching frequency it was possible to refine the principe of a pulse-wide
modulated (triggered) output voltage.

Disadvantageous are the high-frequently earth leakage currents caused by the motor cable and it´s
capacitance against earth.

Furthermore the high slew rate (du/dt) causes
couplings to parallel lines and voltage spikes on the motor terminals.

The real effects are depending on several influences:

- A low switching frequency reduces the leakage current and the losses in the choke.

- A screened motor cable

reduces the couplings to parallel lines but increases the leakage current

and the losses in the choke very high.

- A long motor cable

increases the leakage current and the losses in the choke very high.

- The kind of laying the cable

, e.g. under water, increases the leakage current and the losses in the

choke like a screened cable.

By using an output motor filter AMF and paying attention to the cable lenghts in the table, it is possi­ble to keep the following limits:

Slew rate (du/dt) ≤≤500 V/µs

Peak voltage (U

Peak

) ≤≤1000 V

AMF specification

The output-motor-filter AMF can be mounted in any position.
Because of the losses caused by high switching frequencies or high cable lenghts it is recommended

to place the filter above the inverter. In that case it will be forced cooled and the inverters cooling air
will not be preheated.

Due to the magnetic stray field of the AMF filter the recommended minimum distances above
and on the sides must be observed, that means no mounting plates, steel bars, control lines,
electronic

Once the filter has been assembled on an assembly plate, the frequency inverter is fixed using the 4
drill holes on the filter.

The electric connection between the filter and the frequency inverter is then made using the cable
from the filter, whereby the phase-sequence is irrelevant.

The mains connection is provided at the top of the filter, on terminals L1, L2 and L3. To do this, the
PE cable is connected to the provided bolts.

The filters for >pDRIVE< CX have leakage currents >3.5 mA. Therefore, they must be grounded
with a protective conductor of at least 10 mm². (Personal safety!)

The choke has to be connected directly to the output terminals (U,V, W) of the frequency inverter.
In case of overtemperature of the choke caused by too high switching frequencies and/or too long
cables, the inverter will trip with "external trip".

To prevent the cooling air of the frequency
inverter against pre-heating and to cool the
choke, it is recommended to place the choke
appr. 100...150 mm above the frequency

Options

Remarks

• The switching frequencies of >pDRIVE< CX must be set to a value of 3 kHz or less in
accordance to the table “allowed cable length”

• Because of the higher earth capacitances, parallel motor cables

should only be used for short

distances (see table “allowed cable length”)

• The kind of laying the cable

influences the losses of the choke. The table refers to laying
the cable into a cable location line. Laying under ground or in water increases the leakage
current. The switching frequency has to be reduced furthermore.

• It is not allowed to operate the frequency inverter without an effective connection to earth

. The

connection has to be in accordance to the local regulations for high leakage current (> 3,5 mA).

• It is not allowed to operate the frequency inverter with a standard earth-leakage breaker

, if the

local regulations don´t permit this because of a possible D.C. amount in the leakage current.

Overtemperature protection

1.) Set the switching frequency

in accordance to the table.
Low switching frequencies mean less losses of the choke and reduce the leakage current.
Set parameter b083 to 3 kHz or less.

2.) Integrate the thermoclixon

of the choke for switchoffs in case of overtemperature
e.g. use of terminal 3 as external trip
Parameter C013 = 01 (Inversion of Te. 3)
Parameter C003 = 12 (=EXT, "external trip")

Isolated amplifier TV5, TV6

The >pDRIVE< TV5 is an active isolating amplifier which transforms the input signal (0-10 V) to an
output signal (4...20 mA).
The >pDRIVE< TV6 is an active isolating amplifier which transforms the input signal (0-10 V) to an
output signal (0...20 mA).
It operates according to the principle of optoelectronic potential separation and has three-way
separation between input, output and supply.
The unit requires an auxiliary voltage of 230 V AC and is mounted on a TS35 rail.

The unit works unipolar and should not be

operated with open input.
