Component:
Power Unit
Response:
OFF2
Acknowledgment: IMMEDIATELY
Cause:
The chip temperature of the power semiconductor involved 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
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.
Note:
This fault can only be acknowledged after the alarm threshold for alarm A030252 has been fallen below.
