Cause: A feedback signal for the precharging contactor (ALM, SLM, BLM diode) or the line contactor (BLM thyristor) interconnected
and the monitoring activated.
After switching-in/switching-out the contactor, a correct feedback signal was not received within the monitoring time set in
p0255[0, 2].
Fault value (r0949, interpret binary):
Bit 0: The time set in p0255[0, 2] was exceeded when switching-in/switching-out the contactor.
Bit 1: The precharging contactor was opened while precharging or in the infeed mode (BLM thyristor).
Bit 2: The precharging contactor was switched-in in the OFF state or during infeed operation.
Remedy: - check the monitoring time setting (p0255[0, 2]).
- check the contactor wiring and activation.
- replace the contactor.
Reaction upon A: NONE
Acknowl. upon A: NONE
F30061 (A) Bridging contactor monitoring
Message value: Fault cause: %1 bin
Drive object: All objects
Reaction: OFF2 (NONE, OFF1)
Acknowledge: IMMEDIATELY (POWER ON)
Cause: A feedback signal for the bypass contactor is interconnected and the monitoring activated.
After switching-in/switching-out the contactor, a correct feedback signal was not received within the monitoring time set in
p0255[1, 3].
Fault value (r0949, interpret binary):
Bit 0: The time set in p0255[1, 3] was exceeded when switching-in/switching-out the contactor.
Bit 1: The bypass contactor was opened in operation.
Bit 2: The bypass contactor was switched-in in the OFF state or during precharging.
Remedy: - check the monitoring time setting (p0255[1, 3]).
- check the contactor wiring and activation.
- replace the contactor.
Reaction upon A: NONE
Acknowl. upon A: NONE
A30066 (N) Power unit: overtemperature, alarm capacitor air discharge
Message value: %1
Drive object: All objects
Reaction: NONE
Acknowledge: NONE
Cause: The air discharged from the DC link capacitor has exceeded the alarm threshold.
- ambient temperature too high.
- insufficient cooling, fan failure.
Alarm value (r2124, interpret decimal):
Temperature when reaching the alarm threshold [0.01 °C].
Note:
If operation is unchanged, then the permissible limit value can be exceeded. In this case, fault F30067 is output and the
pulses inhibited.
Remedy: - check whether the fan is running.
- check the fan elements.
- check whether the ambient temperature is in the permissible range.
Note:
This alarm is only withdrawn after the alarm threshold has been fallen below - and the corresponding hysteresis.
Reaction upon N: NONE
