Siemens SINAMICS S210 Operating Instructions Manual page 499

Cause: The drive has detected a ground fault.
Possible causes:
- ground fault in the power cables.
- ground fault at the motor.
- when the brake closes, this causes the hardware DC current monitoring to respond.
- short-circuit at the braking resistor.
Fault value (r0949, interpret decimal):
0:
- the hardware DC current monitoring has responded.
- short-circuit at the braking resistor.
> 0:
Absolute value summation current amplitude.
Remedy: - check the power cable connections.
- check the motor.
- check the cables and contacts of the brake connection (a wire is possibly broken).
- check the braking resistor.
F30024 Power unit: Overtemperature thermal model
Reaction: OFF2
Acknowledge: IMMEDIATELY
Cause: The temperature difference between the heat sink and chip has exceeded the permissible limit value.
- the permissible load duty cycle was not maintained.
- insufficient cooling, fan failure.
- overload.
- ambient temperature too high.
- pulse frequency too high.
See also: r0037 (Drive 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
Reaction: OFF2
Acknowledge: IMMEDIATELY
Cause: The chip temperature of the semiconductor has exceeded the permissible limit value.
- 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 decimal):
Temperature difference between the heat sink and chip [0.01 °C].
