Acknowledge: IMMEDIATELY (POWER ON)
Cause: Alarm A37312 to display overtemperature or fan failure in the HF Choke Module was signaled for longer than 30 s.
Remedy: - the cable between the HF Choke Module and the HF Damping Module has been withdrawn or is defective (X21).
- check the fan of the HF Choke Module and replace if necessary.
- check whether the ambient temperature is in the permissible range.

A37502 (F) HF Damping Module: Damping voltage too high
Message value: %1
Drive object: All objects
Reaction: NONE
Acknowledge: NONE
Cause: The damping voltage has exceeded the alarm threshold.
- a motor harmonic with a high amplitude has coincided with the resonance frequency of the output filter.
- the current controller excessively excites the resonance of the output filter.
If the damping voltage exceeds an inadmissibly high value, F37002 is output.
Alarm value (r2124, interpret decimal):
Damping voltage in the case of a fault [mV].
Remedy: - reduce the motor power in the proximity of the fault-generating frequency.
- check the current controller and if required, adapt.
- if required, use another motor.
Note:
HF Damping Module
Reaction upon F: NONE (OFF1, OFF2, OFF3)
Acknowl. upon F: IMMEDIATELY
N37800 (F) HF Damping Module: Group signal
Message value: -
Drive object: All objects
Reaction: NONE
Acknowledge: NONE
Cause: The HF Damping Module has detected at least one fault.
Remedy: Evaluates other actual messages.
Reaction upon F: NONE
Acknowl. upon F: IMMEDIATELY
A37801 (F, N) HF Damping Module: Sign-of-life missing
Message value: Component number: %1, fault cause: %2
Drive object: All objects
Reaction: NONE
Acknowledge: NONE
Cause: There is a DRIVE-CLiQ communication error between the Control Unit and the HF Damping Module.
Fault cause:
10 (= 0A hex):
The sign-of-life bit in the receive telegram is not set.
Note regarding the message value:
The individual information is coded as follows in the message value (r0949/r2124):
0000yyxx hex: yy = component number, xx = error cause
