Faults and Alarms
List of Fault and Alarm messages
F00004
Inverter Over Temperature
Reaction:
OFF 2
Acknowledge:
Quit fault eg. via DI2
Cause:
•
Inverter overloaded
•
Ventilation inadequate
•
Pulse frequency too high
•
Ambient temperature too high
•
Fan inoperative
Remedy:
Check the following:
•
Load or load cycle too high?
•
Motor power (p0307) must match inverter power (r0206)
•
Pulse frequency must be set to default value
•
Ambient temperature too high?
•
Fan must turn when inverter is running
F00005
Inverter I2T
Reaction:
OFF 2
Acknowledge:
Quit fault eg. via DI2
Cause:
•
Inverter overloaded.
•
Load cycle too demanding.
•
Motor power (p0307) exceeds inverter power capability (r0206).
Remedy:
Check the following:
•
Load cycle must lie within specified limits.
•
Motor power (p0307) must match inverter power (r0206)
F00006
Chip temperature rise exceeds critical levels.
Reaction:
OFF 2
Acknowledge:
Quit fault eg. via DI2
Cause:
•
Load at start-up is too high
•
Load step is too high
•
Ramp-up rate is too fast
Remedy:
Check the following:
•
Load or load step too high?
•
Reduce ramp-up time (P1120).
•
Motor power (p0307) must match inverter power (r0206).
•
Use setting P0290 = 0 or 2 for preventing F00006.
F00011
Motor Over Temperature
Reaction:
OFF 2 (OFF 3)
Acknowledge:
Quit fault eg. via DI2
Cause:
Motor overloaded
Remedy:
Check the following:
•
Load or load step too high?
•
Motor nominal overtemperatures (p0626 - p0628) must be correct
•
Motor temperature warning level (p0604) must match
