F30035 Power unit: Air intake overtemperature
Drive object: All objects
Reaction: OFF1 (OFF2)
Acknowledge: IMMEDIATELY
Cause: Power unit air intake temperature has exceeded the permissible limit value. For air-cooled power units, the limit is at
55 degrees Celsius.
- ambient temperature too high.
- insufficient cooling, fan failure
Fault value (r0949):
Temperature [1 bit = 0.01 °C].
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 after this alarm threshold for alarm A05002 has been fallen below.
F30036 Power unit: Electronics board overtemperature
Drive object: All objects
Reaction: OFF2
Acknowledge: IMMEDIATELY
Cause: Power unit temperature in the module slot of the drive converter has exceeded the permissible limit value.
- insufficient cooling, fan failure.
- overload
- ambient temperature too high.
Fault value (r0949):
Temperature [1 bit = 0.01 °C].
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 after this alarm threshold for alarm A05003 has been fallen below.
F30037 Power unit: Rectifier overtemperature
Drive object: All objects
Reaction: OFF2
Acknowledge: IMMEDIATELY
Cause: Power unit rectifier temperature has exceeded the permissible limit value.
- insufficient cooling, fan failure.
- overload
- ambient temperature too high.
- line supply phase failure.
Fault value (r0949):
Temperature [1 bit = 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 this alarm threshold for alarm A05004 has been fallen below.
A30038 Power unit: Capacitor fan monitoring
Drive object: B_INF
Reaction: NONE
Acknowledge: NONE
Cause: The capacitor fan signals a fault.
Remedy: Replace the capacitor fan in the power unit.
