4 Faults and alarms
4.2 List of faults and alarms
SINAMICS G130/G150
1662 List Manual (LH2), 07/2016, A5E03263479A
Remedy: - check whether the fan is running.
- check the fan elements.
- check whether the ambient temperature is in the permissible range.
Notice:
This fault can only be acknowledged once the permissible temperature limit minus 5 K has been fallen below.
F30037 Power unit: Rectifier overtemperature
Message value: %1
Message class: Power electronics faulted (5)
Drive object: B_INF, VECTOR_G
Component: Power Module Propagation: LOCAL
Reaction: OFF2
Acknowledge: IMMEDIATELY
Cause: The temperature in the rectifier of the power unit has exceeded the permissible temperature limit.
- insufficient cooling, fan failure.
- overload.
- ambient temperature too high.
- line supply phase failure.
Fault value (r0949, interpret decimal):
Temperature [0.01 °C].
Remedy: - check whether the fan is running.
- check the fan elements.
- check whether the ambient temperature is in the permissible range.
- check the motor load.
- check the line supply phases.
Notice:
This fault can only be acknowledged after the alarm threshold for alarm A05004 has been undershot.
