•
When selecting the power of the supply module, proceed as
follows to find out about the required input power.
1. Determine the power profile of all axis modules connected to
the DC-bus by means of the process profile and the load
torques during a system cycle.
2. The power losses are stated in the technical data, for units
the losses are stated during rated power and for motors the
power loss during rated operation. These losses are
assumed to be constant during the whole cycle.
3. Find out the resultant powr by adding the power losses and
the power profiles:
calculate a positive motor power
and a negative generator power.
4. Determin e the effective power during the system cycle:
Do not calculate a negative resultant power (generator
power). These ranges can taken into consideration when
calculating the effective brake power.
5. Select the supply module according to the effective power
during a system cycle:
Please note that the supply module must have enough
capacity to supply the effective peak power and that, in the
event of mains voltage reductions, the permissible power of
the supply module will be reduced according to the reduction
of the mains voltage.
6. If the calculated effective permanent power exceeds the
permissible value of the supply module 9217:
Subdivide the DC-bus sets and install further supply
modules.
13
3.2.2. Screening and earthing
In order to avoid radio interference, care must be taken with the design and
connection of digital drives to avoid EMC disturbances during operation.
Digital drives are not more vulnerable to interference than analog drives, but the
effect is generally different. Interference of analog devices becomes obvious as
irregularities in speed. Interference of digital drives may cause
program errors; therefore it is important that the drives are inhibited
immediately when interference occurs. This is done by setting the
TRIP function (CCr).
In order to avoid these problems, care must be taken with ground
(GND), protective earth (PE) connections as well as screening.
•
Screen control cables and motor cables.
•
Ensure effective screening:
−
a non-earthed conductior should be used to maintain screen
integrity where cahbles are interrupted (terminal strips,
relays, fuses).
Caution!
To increase the EMC (electromagnetic compatibility), the reference GND is
connected to the protective earth (PE) inside the drive.
Fehler! Es
ist nicht
möglich,
durch die
To ensure an optimum interference suppression, the screening and the GND-PEconnection is made differently for single drive and multi drive
networks.
Single drive
•
Connect the screen of the control cables to PE of the drive at
one end to avoid earth loops.
•
GND and PE are connected by a jumper inside the drive.
•
In case of firmly installed computer connections, a mains
isolation (e.g. Lenze Converter 2101) is mandantory between
computer and axis module.
•
The screens of the motor cables
−
should be as large as possible.
−
connected to the two sides.
14
Multi drive networking
•
When laying the ground cables, care must be taken that there
are no ground loops. To ensure this, the GND-PE connection
must be removed in every drive. For the 9200 drives, turn the
four screws on the cover one haft turn CCW and pull out the
control board. Remove the jumper PE-BR on the board 9220
MP. CAUTION: Ensure that the mains has been disconnected
and the drive has been switched off at least 5 minutes before
removing any parts.

as the electronics insulation (SubD plug) does not allow
voltages >50V~ AC at PE.
•
In case of firmly installed computer connections, a mains
isolation (e.g. Lenze Converter 2101) is mandatory between
computer and axis module.
•
The individual cable screens must be connected to external
insulated centreal points, which are then connected to the PE

3.2.3. Radio interference suppression
According to § 13 and § 14 of the legislation of the European
Community relating to the electromagnetic compatibility of devices
(EMVG v. 09.11.92) the national standards and regulations are only
interim standards vilid until December 31, 1995. In addition, the
harmonized European standards can be fulfilled following the
recommendations below. Measures against radio interference
suppression depend on the site of the device to be installed:
Previous national standards
The application without radio interference suppression in electrical
systems within connected working areas or industrial premises can
only be allowed if, outside the industrial premises, the limit values
according to VDE 0871/6.78, class B are not exceeded (General
allowance according to the standard on the operation of highfrequency devices of December 14, 1984, official no. 1045/1046).
For operation within residential areas or when exceeding the limit
value class B outside of industrial premises, radio interference
suppression according to VDE 0871, limit value class B is required.
Future hormonized standards
The standard prEN 50081-2 is valid for the radio interference
suppression.
It refers to standard EN 55011 (VDE 0875, part 11, limit value class
A and B).
•
Within industrial premises, which are not connected to the public
low-voltage supply, the limit values to EN 55011, limit value
class A apply.
•
Within residential areas or industrial premises, which are
connected to the plublic low-voltage supply, the limit values to
EN 55011, limit value class B apply.
Radio interference suppression to EN 55011, limit value class
A or B, can be achieved by:
•
Using a suitable mains filter and screening of motor cables,
brake resistor cables and the power cable between mains filter
and inverter (for recommended mains filters see "Accessories").

4.1.1. Mains and motor connection
Caution!
All power terminals carry mains potential up to 5 minutes
after mains disconnection.
The DC-bus terminals +UG -UG and the PE terminals of the supply
and axis module must be connected by means of busbars
(accessory kit).
17
4.1.2. External brake resistor
To increase the permanent brake power, an external brake resistor
with a higher permanent power can be installed instead of the
internal resistor. In this case, the internal brake resistor must be
disconnected.
Disconnection of the internal resistor:
1. Remove right side of the supply module housing 9210, when
no voltage is applied.
2. Disconnect spade plug.
3. Connect spade plugs to tabs on the housing.
4. Close housing again.

(for recommended resistors see chapter "Accessories"). The
surface temperature of the resistor may reach 360°C.
Caution!
When using brake resistors without overload protection, the resistors may burn due
to a fault (e.g. mains overvoltages >528V, application specific overload or internal
faults).

4.2.Control connections of supply module
4.2.1. Overheat of internal brake resistor (9210 X1)
The thermal contact (capacity 230V/10A) of the internal brake
resistor can be accessed via the connector X1 of the supply
module. It can be used to switch off the mains in case of overload
of the internal brake resistor (see also: External brake resistor).
Caution!
Unlike previous models of this series, the connector X1 of the supply module does
not have to be bridged any more. This connector cannot be used for the monitoring
of an external thermal contact and the like! To protect the inverter, wiring according
to figure "Wiring using the internal brake resistor" (page 19) is necessary.
4.2.2. Mains and DC-bus monitoring (9210 X3)
At X3 of the power supply module several signals are available,
that give information about the status of the mains. The wiring of
this terminal is not necessary to make the device work. If the
software feature mains failure with DC-bus controlling is required,
the terminals X3,1 and X3,3 must be wired. By using an external 24
V supply there is an optoisolated signal of mains failure at terminal
X3,5.
For further information see: Parameter setting, page 50.

4.2.3. State bus
By means of the state bus X6, the supply module gives status
information like ready, overvoltage, and heat sink or resistor
overtemperature to the connected axis modules. The four state bus
cables must be taken from the supply module to the axis modules.
The terminals in the axis module which are next to each other are
internally bridged.

Master frequency selection
For speed set value selection by means of a master frequency, the
9-pole SubD Dig.Set (X2) is used. As master frequency signal
either the simulated encoder signal of the master drive or an
incremental signal source with two TTL complementary signals
shifted by 90° el. can be used. The zero track of the master
endcoder will not be evaluated. The maximum input frequency is
300 kHz. The current consumption per channel is 6 mA.l.

2.Basics of parameter setting
The drive can be adapted to your specific applications by
parameter setting of the axis modules. The possible settings are
arranged in the form of codes, which are numbered in ascending
order and start with the letter "C". Each code provides several
parameters which can be selected according to the application.
Parameters can be direct values of a physical unit (e.g. 50Hz or
50% related to f
information (e.g. -0- = controller inhibited, -1- = controller enabled).
In cases where the parameters represent values of physical units, it
is possible to vary the increment.
Example: The acceleration and deceleration can be set in
increments of 0.01 s up to 1 s and in increments of 0.1 s from 1 s
upwards.
For codes with more than 5 digit values, the keypad operation is
different: In the parameter level, the cursor can be shifted to enter
large values. This is done by pressing SH+ ▲ and SH+▼ (see
example on page 44).
In some codes, parameters can only be read but not changed.
In the factory setting, only those codes are displayed which are
necessary for the most common applications. For activation of the
extended code set see code table C 000.
) or numerical codes giving certain status
dmax
2.1.Change parameters
Each code has a factory set parameter which can be changed.
There are three different ways of selecting and confirming a new
parameter, depending on the code:
Direct acceptance
The servo axis immediately accepts the new parameter, i.e. while
you change it using the ▲ or ▼-key. This is possible even when the
drive is running. Parameters which are immediately accepted are
marked with
Acceptance with SH + PRG
The axis accepts a new parameter when SH + PRG are pressed.
This is possible even with the drive running. First press SH and
then in addition PRG. The display shows --ok-- for 0.5 seconds.
The axis module now works with the new parameter. The key
combination SH and PRG can be compared to the "return" key on
your computer keyboard. If you have to set a parameter of a code
in this way, the code table shows the symbol
ON-LINE
in the code table.
SH + PRG
.
41
Acceptance with SH + PRG with controller inhibit
The axis module accepts the new parameter when it has been
inhibited prior to pressing SH + PRG. Inhibit the controller e.g. by
pressing STP. First press SH and then in addition PRG. The
display shows --ok-- for 0.5 seconds. The axis module works with
the new parameter when the controller is released again. If you
have to set a parameter of a code in this way, the symbol
appears in the code table.
2.2.Save parameters
•
When commissioning for the first time, the parameter set 1 is
factory-set. After the acceptance, new parameters are saved in
the RAM, i.e. they are saved until the controller is disconnected
from the mains.
If you do not want to lose your setting when connecting the
controller to the mains, save them permanently:
1. Select code C003.
2. Select parameter set 1 by entering -1- .
3. Press SH first, and then additionally PRG. --ok-- will be
displayed.
4. Now you can disconnect the servo controller from the mains.
Your settings are permanently saved under "parameter set
1".
•
Password
The input of a password prevents unauthorized changes of
parameters or code levels.
2.3.Load parameter
If you only need one parameter set, you can permanently save
your changes under parameter set 1. After every mains connection,
parameter set 1 is loaded automatically.

3.Commissioning
The following notes on the commissioning do not explain all
possibilities of parameter settings. The code table at the end of the
chapter lists and describes all codes in detail.
Caution!
Before commissioning, check the wiring of the controller.
Typical faults are:
•
incorrect screening of the cables
•
earth or ground current loops
and if Lenze system cables are not used:
•
incorrect connection of the motor phases
•
incorrect connection of the resolver terminals
The axis modules are factory-set for terminal control and parameter
setting via keypad for speed control with asynchronous motor,
resolver feedback and analog set value provision at terminal 8
(C005 = 11). For this standard application, the basic parameters
are already programmed. Start entering the motor nameplate data
(see page 47) for commissioning.
For all other applications, the basic parameters must be selected.
3.1.Basic parameter setting
Before setting the parameters of the axis module, the controller
must be inhibited, i.e. terminal 28 open, RFR ENABLE switch open,
or STP key pressed.
•
C000 code set
All codes in the inverter are arranged in different code sets. With
factory setting, the standard code set is activated. It contains all
codes which are required for the most common applications.
By selecting the extended code set under code C000, the
keypad also shows those codes which are suitable for special
applications. There is also a service code set which is not
accessible in general.
If you want to protect your parameter settings from nonauthorized access you can enter a password in the form of a
three-digit number. By defining a password, the parameters of
the standard code set can only be read, but not changed when
the password is not entered. The parameters of the extended
code set can neither be read nor changed.
First enter the password under C094 and then set code C000 to
"standard code set read only". After this, the setting of code
C000 can only be changed when the programmed password is
entered.
45
•
C001 Operating mode
Selection between keypad control or control via LECOM-A/B
interface or parameter setting via LECOM interface. For control
or parameter setting via LECOM interface, the drive must, in
addition, be given an address in code C009 (code set -2-).
To change the operating mode, open RFR switch (X5 terminal
28 open). The functions RFR ENABLE, QSP, Trip set and Trip
reset are not affected and can be controlled via terminals.
After selecting the control via Lecom (C001 = 3, 5, 6, 7) the
controller must be enabled via the selected interface. If
Lecom1 control (C001 = 3) has been selected, although the
interface is not connected, the controller can be enabled again
by selecting C001 = 1, and then C040 = 1. If LECOM 2 control
has been selected (C001 = 5, 6, 7) if the interface is not
connected, the controller remains inhibited even after changing
C001. To enable the controller again, select under C001 a
parameter other than 5, 6, 7 save the parameter and
disconnect the controller from the mains. After reconnection,
the controller can be enabled again.
•
C005 Configuration
Other control modes (e.g. torque control) or alternative methods
of producing the reference signal are available. The
configuration can only be changed whilst in code set -2-.
Caution!
When changing the configuration, control structure, motor and encoder and
terminal assignment are changed.
•
C025 Encoder
The set value and the actual value encoder can be selected
under C025 (PPR). Encoder constants are set under C026.
The master/slave ratio is set under C027.
•
Master frequency Dig.Set
The master frequency provision is set under C025 -3- via input
Dig.Set (X2); then the increments per revolution are set in code
C026. It is also possible to set the speed ratio between the
master and slave, this adjustment is made under code C027.

4.1.2. Setting
These setting instructions are meant as guideline and must not
always decelerate the machine to standstill before reaching the
undervoltage threshold. The parameter setting of the codes, which
influences the DC-bus control during mains failure detection (C079,
C080, C228, C236, C237), depend on the size of the drive
configurations and the mechanical features of the system.
There are minimum speeds at which the energy of the mechanical
system is not high enough to compensate the losses which occur
during the controlled deceleration (switched-mode power supplies,
inverter, machines).
Aim:
•
The aim is to have a controlled speed deceleration that allows a
DC-bus voltage value which remains higher than the
undervoltage threshold for as long as possible.
As soon as the value falls below this threshold, pulse inhibit will
be set and the drive will coast to standstill.
•
The brake chopper should not be activated during the controlled
deceleration of the speed.
Therefore, the parameter setting of the DC-bus control should
be "softly". It is not very important whether the DC-bus can be
loaded to the voltage set under C236.
Required measuring units:
•
Oscilloscope,
at least 2 channels, if possible with memory.
Test set-up:
•
Connect channel 1 of the oscilloscope with X5,62 of the axis
module (speed monitor).
•
Connect channel 2 of the oscilloscope with X3,2 of the supply
module (DC-bus monitor).
•
If available, connect channel 3 of the oscilloscope with X5,44 of
the axis module (RDY-output).
Presettings:
1. Set the speed controller of the axis module drive configuration
as usual.
2. Activate the mains failure detection of the master drive (C229 =
-1-).
If the function is activated, the RDY-output changes from the
HIGH level to the LOW level. As soon as the speed is
decelerated to 0, the RDY-output re-changes to HIGH.
3. The relevant codes must be set as follows:

53
Setting course:
1. Select a medium speed as set value according to the occuring
speed range of the system.
2. Switch-off the mains.

3. Increase C079 to reach the undervoltage threshold at a speed
as low as possible. For very small final speed values, you may
reduce C228.
4. Repeat steps 1.) to 3.) at maximum and minimum system
speed.
5. Reduce C080 at maximum system speed until the DC-bus
voltage does no longer overshoot the brake-chopper threshold
(see fig. 2).
You may also reduce C237 to limit the speed decrease during
deceleration.

4.2.Homing mode
•
C250 Homing mode
In the homing mode (C250 = -0-) the increments of the master
frequency at the DIG.SET input are processed as a relative
change of angle. By activating the homing mode (C250 = -1-) it
is possible to refer to an absolute angle position of the motor
shaft. The homing mode can only be activated if the controller is
inhibitied. It is initiated by means of JOG function.
Functional sequence:
Start the homing mode by means of the JOG function enable.
The RDY signal indicates "not ready". The drive runs at the
selected JOG speed. After blocking the JOG signal (e.g. by
means of a proximity switch), the drive continues to run to the
home position and stops. The RDY signal indicates "ready".
If controller inhibit or QSP are activated during homing, the RDY
signal remains "not ready" until the homing process is finished.

The shift range of the home position is one revolution of the
motor shaft. 360° is resolved into 2048 steps. The adjustment
can be made ON-LINE when the motor is running. The zero
pulse of the encoder emulation X4 is also resolved in 256 steps.
•
C254 Amplification of the angle controller
The angular controller is active when using a master frequency
DIG.SET input or if the homing mode is active. By selecting
Vpw=0, the angular controller is deactivated. In this case, the
master frequeny is processed as speed set value and not as set
angle increments. Before adjusting the amplification of the
angular controller, the speed controller must be optimized.
•
C159 Homing OK
C159 displays whether the homing was successful or not:
C159 = -1- homing successfully completed
C159 = -0- homing not completed
C159 may also be used for simulating a homing mode:
Set C159 = -1- and manually activate the angle offset under
C252.

4.3.Further additional functions
•
C004 Switch-on display
Entering a code number under C004 determines which
parameter is to be displayed after switching-on.
•
C018 Chopper frequency
The chopper frequency determines the noise level. The chopper
frequency can either be 8 or 16 kHz. Changing the chopper
frequency changes the admissible permanent load of the axis
module.
•
C255 Following error limit
If an following error exceeds the value entered under C255
during master frequency operation (C005 = -13- or -21-) and an
amplification of the angle controller of C254 > 0, an internal
signal will be generated for the error status >>Following error
limit exceeded<< . If this signal is applied to the terminal Q
(X5,42) via C117, the Q
HIGH to LOW as soon as the set limit value is exceeded.
For following errors of more than 3188 increments, also the
RDY message will be set to LOW and >>following error<< will
be displayed.

5.Serial interfaces
The 9200 servo axis modules can communicate via the serial
interfaces LECOM1 and LECOM2 with superimposed hosts (PLC
or PC) as well as Lenze operating units.
The LECOM1 interface (connector X1) is used to process the
LECOM A/B protocol. The LECOM1 interface can also be used to
connect devices to the RS 232C standard (LECOM-A) or to the RS
485 standard (LECOM-B). The interface is suitable for parameter
setting, monitoring, diagnosis and process control.
For more demanding applications, a field bus connecting module
can be used. For the parameter setting, this interface is generally
called LECOM2.
The following bus systems are available:
•
Interbus-S interface module 2110
•
Profibus interface module 2130
5.1.LECOM1 interface X1
The standard serial interface X1 fulfills the standard RS 232 C as
well as the standard RS 485.
Using the common RS 232 C interface, simple point-to-point
connection with a maximum cable length of 15 m can be achieved.
Almost every personal computer (PC) or other master system is
equiped with this interface. For several drives and larger distances,
the RS 485 interface must be used. Only two wires are used to
enable the communication of up to 31 controllers via a maximum
distance 1200 m.
The LECOM A/B protocol is based on the 1745 ISO standard and
supports up to 90 controllers. It recognizes faults and therefore
avoids the transmission of faulty data.

The automation communication must
be activated when using an automation module or a field bus connection LECOM2. If the communication is
enabled, without communicating to
the other side, the controller remains
inhibited. The communication via the
automation interface can be activated
independently of the operatíng mode
C001 when the controller is inhibited
(C040 = 0).
Caution!
To ensure a faultless initialization, the
LECOM interface may only be
accessed after one sec.
Note:
The setting will not be overwritten
when loading factory setting!

1.Monitoring messages
The servo drives of the 9200 series have numerous monitoring
functions, to protect against non-permissible operating conditions.
When such a protective function is activated, it either causes a
corresponding message on the controller display and pulse inhibit
(IMP) or, in addition (TRIP) setting. The type of fault is immediately
displayed. After having removed the fault, the pulse inhibit is
released automatically. Faults, however, causing a TRIP setting
must be reset und C067 by pressing SH+PRG or by a high signal
on input X5, terminal 27, TRIP reset.

LU Undervoltage
The mains voltage of the supply module is monitored by
measuring the DC bus voltage. If the DC bus voltage decreases
below 330V ± 4%, the servo controllers cannot continue to
operate. The axis modules are inhibited via the State Bus. If the
mains voltage increases above 430V ± 3% again, the axis
modules are released again.
1.3.Monitoring with TRIP setting
•
OC1 Short circuit
OC1 is displayed if the current controller of the axis modules is
not able to limit the output current of the controller to the peak
current. Check if there is a short circuit in the motor or the motor
supply cable.
•
OC2 Earth fault
An earth fault current is detected if the total of the phase output
current is not 0. Check if there is an earth fault in the motor or
the motor supply cable.
Caution
Before switching on the mains again, it must be ensured that the
earth fault has been removed. The inverter free wheeling diodes
may be destroyed by earth faults.

OC5 Overload axis module (I · t)
The servo controllers can be overloaded up to their peak current
for a certain period of time. The possible duration of overload
without Trip setting depends on its intensity. When exceeding
the time limit, the fault OC5 "overload" is displayed. The
current/time ratios that do not lead to Trip setting are shown in
the overload diagrams below. These overload diagrammes
show permissible overcurrents, necessary recovery times and
load cycles. Take into consideration that the rated currents of
the axis modules depend on the chopper frequency set under
C018 (see Technical data, page 6).

OH1 Overtemperature supply module
The temperature monitoring on the supply module detects
overtemperatures of the heat sink, the mains input bridge, the
brake chopper and the internal brake resistors. Possible reasons
are:
overload of the supply module (supply module power < total
•
axis module power).

OH2 Overtemperature heat sink axis module
The heat sink is monitored by a thermal contact. If the fault OH2 is
displayed, either the ventilation is not sufficient or defective, or the
ambient temperature is > 45°C. Fault reset is only possible after the
heat sink temperature has been reduced below 45°C.
EEr External TRIP
The voltage at the TRIP-SET input X5 terminal 26 must be < 5V.
Otherwise, the external TRIP will be set.
SD2 Wire breakage resolver or resolver cable
The electrical resistance of the resolver cables is monitored. If the
line resistance is too high due to a line breakage or an interruption
in the resolver, fault SD2 "wire breakage" is displayed.
U15 Supply voltage interrupted
Check the Vcc-15V connection X5 terminal 20 for external short
circuit.
CCr System fault
Programme sequence error in the micro processor. A system fault
occurs with interference in the electronics caused by incorrect
screening or non-screened cables or due to ground or earth loops
in the wiring. The fault may also occur after short mains
interruptions (t < 1 min) if the controller was switched off while there
was another non-acknowledged fault.
Pr Parameter loss
Program sequence error in the microprocessor which is caused by
interference in the electronics due to incorrect screening or nonscreened cables or ground or earth current loops in the wiring. The
interference resulted the loss of the stored parameters. After TRIP
reset and before enabling the controller again, a new parameter
setting is required.
CEO
Communication error with the automation module. The error occurs
when the automation module is activated by C370-1, but the
communication is interrupted.
UEr Unknown fault
This fault occurs in the fault memory if the hardware monitoring
sets TRIP, however, the software cannot identify the fault (e.g. in
case of interrupted supply voltage.

2.LED displays
The LED displays clearly indicate the momentary operating state of
the controller even from greater distances. The axis modules are
provided with 3 LEDs in the operating terminal, the supply has 2
LEDs at the front side.
