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
