12.3 Faults and alarms
F30022
Power unit: Monitoring U_ce
Message class:
Ground fault / inter-phase short-circuit detected (7)
Message value:
Fault cause: %1 bin
Component:
Power Unit
Response:
OFF2
Acknowledgment: POWER ON
Cause:
In the power unit, the monitoring of the collector-emitter voltage (U_ce) of the semiconductor has responded.
Possible causes:
- Fiber-optic cable interrupted.
- The power supply for power semiconductor gating missing.
- Short-circuit at the power unit output.
- Defective semiconductor in the power unit.
Fault value (r0949, interpret binary):
Bit 0: Short-circuit in phase U
Bit 1: Short-circuit in phase V
Bit 2: Short-circuit in phase W
Bit 3: Short-circuit in phase N
See also: r0949 (Fault value)
Remedy:
- Check the fiber-optic cable and if required, replace.
- Check the power supply for the power semiconductor gating (24 V).
- Check the power cable connections.
- Select the defective semiconductor and replace.
F30024
Power unit: Overtemperature thermal model
Message class:
Power electronics faulted (5)
Message value:
Power semiconductor: %1, temperature: [0.01 degrees C] %2
Component:
Power Unit
Response:
OFF2
Acknowledgment: IMMEDIATELY
Cause:
The temperature difference between the power semiconductor involved and the heat sink has exceeded the permissible
fault threshold.
- The permissible load duty cycle was not maintained.
- Insufficient cooling, fan failure.
- Overload.
- Ambient temperature too high.
- Pulse frequency too high.
Fault value (r0949, interpret hexadecimal):
yyyyxxxx hex: yyyy= Power semiconductor, xxxx = Temperature in 0.01°C
See also: r0037 (Power unit temperatures)
Remedy:
- Adapt the load duty cycle.
- Check whether the fan is running.
- Check the fan elements.
- Check whether the ambient temperature is in the permissible range.
- Check the motor load.
- Reduce the pulse frequency if this is higher than the rated pulse frequency.
F30025
Power unit: Chip overtemperature
Message class:
Power electronics faulted (5)
Message value:
Power semiconductor: %1, temperature: [0.01 degrees C] %2
