F30036
Power module: Overtemperature electronics unit
Reaction:
OFF1 (OFF2)
Acknowledge:
IMMEDIATELY
Cause:
Power module 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 module: Overtemperature rectifier
Reaction:
OFF2
Acknowledge:
IMMEDIATELY
Cause:
Power module 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.
F30040
Power module: Undervoltage 24 V
Reaction:
OFF2
Acknowledge:
power on
Cause:
Failure of the 24 V power supply for the power module.
- the 16 V threshold was fallen below for longer than 3 ms.
Fault value (r0949):
24 V voltage [1 bit = 0.1 V].
Remedy:
Check the 24 V DC voltage supply to power module.
A30041 (F)
Power module: Undervoltage 24 V
Reaction:
NONE
Acknowledge:
NONE
Cause:
24 V power supply fault for the power module.
- the 16 V threshold was fallen below.
Fault value (r0949):
24 V voltage [1 bit = 0.1 V].
Remedy:
Check the 24 V DC voltage supply to power module.
Reaction upon F:
NONE (OFF1, OFF2, OFF3)
Acknowledge
IMMEDIATELY (power on)
upon F:
A30042
Power module: Fan operating time reached or exceeded
Reaction:
NONE
Acknowledge:
NONE
