Error messages

Tip!
If you use GDC or a fieldbus module to find out about an error (C0168/x), the error message will be
represented by an error number.
Cause
-
Strong interferences on control cables
Ground or earth loops in the wiring
Error during the transfer of control commands via the
automation interface X1
CAN_IN_1 object receives faulty data, or communication is
interrupted
CAN_IN_2 object receives faulty data, or communication is
interrupted
CAN_IN_3 object receives faulty data, or communication is
interrupted
Controller has received too many incorrect telegrams via
system bus X4 and has disconnected from the bus
A digital input assigned to the TRIP set function has been
activated
During initialization of the controller, an incorrect power
stage was detected
Sensor of the heat sink temperature detection indicates
undefined values
Sensor of indoor temperature detection indicates undefined
values
Measuring of the characteristic failed
Motor too small (P
No identification of the motor parameters
A current-carrying motor phase has failed
The current limit is set too low
This monitoring is not suitable for:
• Synchronous servo motors
• for rotating-field frequencies > 480 Hz
DC bus voltage is smaller than the value fixed under C0173 Check mains voltage
Active load too high (e.g. for hoists)
Drive is not speed-controlled, torque excessively limited
The current speed has been detected incorrectly.
Short-circuit
Excessive capacitive charging current in the motor cable

Remedy
-
Screen the control cables
Ensure PE wiring complies with EMC requirements ( 
LEERER MERKER )
Plug in the automation module firmly and, if necessary, bolt
it down
Check cable at X4
Check transmitter
Increase monitoring time under C0357/1 if necessary
Check cable at X4
Check transmitter
Increase monitoring time under C0357/2 if necessary
Check cable at X4
Check transmitter
Increase monitoring time under C0357/3 if necessary
Check wiring
Check bus termination (if any)
Check screen contact of the cables
Check PE connection
Check bus load:
Reduce baud rate (observe cable length)
Check external encoder
Contact Lenze
Contact Lenze
Contact Lenze
Contact Lenze
Check motor cable
Select bigger motor
Enter data of the nameplate of the connected motor
Check motor;
Check supply module
Set a higher current limit under C0599
Deactivate monitoring with C0597= 3
Check supply cable
Check drive dimensioning
Increase torque limit
Check encoder selection (C0025)
Check motor data
Find out cause of short-circuit; check cable
Use motor cable which is shorter or has a lower
capacitance
