F0023 Output Fault; F0024 Rectifier Temperature Too High; F0030 Fan Failed; F0040 Fault, For Automatic Calibration - Siemens MICROMASTER 440 Parameter Manual

Faults and Alarms

F0023 Output fault

Quit
Refer to F0001
Cause
- one output phase has not been correctly connected.
Diagnosis & Remedy
Please check the following:
- are the connections at the motor terminal box o.k. ?
- are the motor cable connections at the inverter o.k. ?

F0024 Rectifier temperature too high

Quit
Refer to F0001
Cause
- inadequate cooling
- fan is not operational
- ambient temperature is too high.
Diagnosis & Remedy
Please check the following:
- does the fan rotate when the inverter is powered-up (A0520, A0521) ?
- is the pulse frequency set to the factory setting ? If required, reset.
- is the ambient temperature within the permissible limits (A0520, A0521) ?

F0030 Fan failed

Quit
Refer to F0001
Cause
- fan no longer functions
Diagnosis & Remedy
- fault cannot be suppressed if an AOP or BOP is connected.
- a new fan is required.
F0035 Restart after n
Quit
reset fault memory or Power On / Stop
Cause
- restart fault after n attempts, refer to P1211

F0040 Fault, for automatic calibration

Quit
Refer to F0001
Cause
- a calibration error has occurred for the automatic calibration of the analog inputs / outputs or the current
actual value sensing.
- the calibration is only carried-out once in the factory.
- a fault F0040 is therefore only to be expected while the inverter is being manufactured and not in
operation.
Diagnosis & Remedy
- change the drive
