4 Faults and alarms
4.2 List of faults and alarms
Remedy:
- check the motor data and if required, recalculate the control parameters (p0340 = 3). As an alternative, run a motor
data identification (p1910 = 1, p1960 = 1).
- check the motor circuit configuration (star/delta).
- check the motor load.
- check the power cable connections.
- check the power cables for short-circuit or ground fault.
- check the length of the power cables.
A30034
Power unit: Internal overtemperature
Message class:
Power electronics faulted (5)
Reaction:
NONE
Acknowledge:
NONE
Cause:
The alarm threshold for internal overtemperature has been reached.
If the temperature inside the unit continues to increase, fault F30036 may be triggered.
- ambient temperature might be too high.
- insufficient cooling, fan failure.
Alarm value (r2124, interpret decimal):
Only for internal Siemens troubleshooting.
Remedy:
- check the ambient temperature.
- check the fan for the inside of the unit.
A30042
Power unit: Fan has reached the maximum operating hours
Message class:
Power electronics faulted (5)
Reaction:
NONE
Acknowledge:
NONE
Cause:
The maximum operating time of at least one fan will soon be reached, or has already been exceeded.
Alarm value (r2124, interpret binary):
Bit 0: heat sink fan will reach the maximum operating time in 500 hours.
Bit 1: heat sink fan has exceeded the maximum operating time.
Bit 8: internal device fan will reach the maximum operating time in 500 hours.
Bit 9: internal device fan has exceeded the maximum operating time.
Note:
The maximum operating time of the heat sink fan in the power unit is displayed in p0252.
The maximum operating time of the internal device fan in the power unit is internally specified and is fixed.
Remedy:
For the fan involved, carry out the following:
- replace the fan.
- reset the operating hours counter (p0251, p0254).
F30051
Power unit: Motor holding brake short circuit detected
Message class:
External measured value / signal state outside the permissible range (16)
Reaction:
OFF2
Acknowledge:
IMMEDIATELY
Cause:
A short-circuit at the motor holding brake terminals has been detected.
Fault value (r0949, interpret decimal):
Only for internal Siemens troubleshooting.
Remedy:
- check the motor holding brake for a short-circuit.
- check the connection and cable for the motor holding brake.
