3.3 Error messages
Tip!
If you use GDC or a fieldbus module to find out about a n error (C0168/x), the error message will be
represented by an error number.
Display Error Cause Remedy
--- No error - -
CCr System fault Strong interferences on control cables Screen the control cables
Ground or earth loops in the wiring Ensure PE wiring complies with EMC requirements (
LEERER MERKER )
CE0 Communication error Error during the transfer of control c ommands via the
automation interface X1
Plug in the automation module firmly and, if necessary, bolt
it down
CE1 Communication error at
the process data input
object CAN_IN_1
CAN_IN_1 object receives faulty data, or communication is
interrupted
Check cable at X4
Check transmitter
Increase monitoring time under C0357/1 if necessary
CE2 Communication error at
the process data input
object CAN_IN_2
CAN_IN_2 object receives faulty data, or communication is
interrupted
Check cable at X4
Check transmitter
Increase monitoring time under C0357/2 if necessary
CE3 Communication error at
the process data input
object CAN_IN_3
CAN_IN_3 object receives faulty data, or communication is
interrupted
Check cable at X4
Check transmitter
Increase monitoring time under C0357/3 if necessary
CE4 BUS-OFF state Controller has received too many incorrect telegrams via
system bus X4 and has disconnected from the bus
Check wiring
Check bus termination (if any)
Check screen contact of the cables
Check PE c onnection
Check bus load:
Reduce baud rate (observe cable length)
EEr External fault (TRIP-Set) A digital input assigned to the TRIP set function has been
activated
Check external encoder
H05 Internal error Contact Lenze
H07 Incorrect power stage During initialization of the controller, an incorrect power
stage was detected
Contact Lenze
H10 Sensor fault: heat sink
temperature
Sensor of the heat sink temperature detection indica tes
undefined values
Contact Lenze
H11 Sensor fault indoor
temperature
Sensor of indoor temperature detection indic ates undefined
values
Contact Lenze
ID1 Fault during motor
identification
Measuring of the characteristic failed
Motor too small (P
motor
% P
controller
)
Check motor cable
Select bigger motor
ID2 Fault during motor
identification
No identification of the motor parameters Enter data of the nameplate of the connected motor
LP1 Motor phase failure
A current-carrying motor phase has failed Check motor;
Check supply module
The current limit is set too low Set a higher current limit under C0599
This monitoring is not suitable for:
•
Synchronous servo motors
•
for rotating-field frequencies > 480 Hz
Deactivate monitoring with C0597= 3
LU Undervoltage DC bus voltage is smaller than the value fixed under C0173 Check mains voltage
Check supply cable
r
MAX
Max. plant speed
exceeded (C0596)
Active load too high (e.g. for hoists) Check drive dimensioni ng
Drive is not speed-controlled, torque excessively limited Increase torque limit
The current speed has been detected incorrectly. Check encoder selection (C0025)
Check motor da ta
OC1 Short-circuit Short-circuit
Excessive capacitive charging current in the motor cable
Find out cause of short-circuit; check cable
Use motor cable which is shorter or has a lower
capacitance
