Faults and Alarms
List of faults and alarms
Cause:
Fault detected on the DRIVE-CLiQ component involved. Faulty hardware cannot be excluded.
Fault value (r0949, hexadecimal):
20: Error in the telegram header.
23: Receive error: The telegram buffer memory contains an error.
42: Send error: The telegram buffer memory contains an error.
43: Send error: The telegram buffer memory contains an error.
60: Response received too late during runtime measurement.
61: Time taken to exchange characteristic data too long.
Remedy:
- check the DRIVE-CLiQ wiring (interrupted cable, contacts, ...).
- check the electrical cabinet design and cable routing for EMC compliance
- if required, use another DRIVE-CLiQ socket (p9904).
- replace the component involved.
F34895
CU DRIVE-CLiQ: Cyclic data transfer error
Reaction:
NONE (OFF1, OFF2)
Acknowledge:
IMMEDIATELY
Cause:
A DRIVE-CLiQ communications error has occurred between the control unit and the voltage sensing module.
Fault value (r0949, hexadecimal):
0B: Synchronization error during alternating cyclic data transfer.
Remedy:
- carry-out a POWER ON.
See also: p9915
F34897
DRIVE-CLiQ: No communications to the components
Reaction:
OFF2 (DCBRAKE, ENCODER, NONE, OFF1, OFF3, STOP1, STOP2)
Acknowledge:
power on (IMMEDIATELY)
Cause:
Communications with the DRIVE-CLiQ component specified by the fault value is not possible.
One cause can be, e.g. that a DRIVE-CLiQ cable has been withdrawn.
Fault value (r0949, decimal):
Component ID.
Remedy:
- check the DRIVE-CLiQ connections.
- carry-out a POWER ON.
F34899 (N, A)
VSM: Unknown fault
Reaction:
NONE (OFF1, OFF2, OFF3)
Acknowledge:
IMMEDIATELY (power on)
Cause:
A fault occurred on the voltage sensing module that cannot be interpreted by the control unit firmware. This can occur
if the firmware on the voltage sensing module is more recent than the firmware on the control unit.
Fault value (r0949, decimal):
Fault number.
If required, the significance of this new fault can be referred to in a more recent description of the control unit.
Remedy:
- replace the firmware on the voltage sensing module by an older firmware version (r0xyz).
- upgrade the firmware on the control unit (r0018).
Reaction upon N:
NONE
Acknowledge
NONE
upon N:
Reaction upon A:
NONE
Acknowledge
NONE
upon A:
A34903 (F, N)
VSM: Error I2C bus
Reaction:
NONE
Acknowledge:
NONE
Cause:
An error has occurred in while accessing via the internal TM I2C bus.
Remedy:
Replace the terminal module.
Reaction upon F:
NONE
Acknowledge
IMMEDIATELY (power on)
upon F:
3-642
