3.2 List of Fault and Alarm messages
Product: G120, Version: 3005200, Language: eng
F00001 (N) Overcurrent
Reaction: OFF 2
Acknowledge: Quit fault eg. via DI2
Cause: • Motor power (p0307) does not correspond to the inverter power (r0206)
• Motor lead short circuit
• Earth faults
Remedy: Check the following:
• Motor power (p0307) must correspond to inverter power (r0206).
• Cable length limits must not be exceeded.
• Motor cable and motor must have no short-circuits or earth faults
• Motor parameters must match the motor in use
• Value of stator resistance (p0350) must be correct
• Motor must not be obstructed or overloaded
• Increase Ramp-up time (p1120)
• Reduce Starting boost level (p1312)
Note: • r0949 = 0: HW reported
• r0949 = 1: SW reported
F00002 Overvoltage
Reaction: OFF 2
Acknowledge: Quit fault eg. via DI2
Cause: • Main supply voltage too high
• Motor is in regenerative mode
Remedy: Check the following:
• Supply voltage (p0210) must lie within limits indicated on rating plate .
• Vdc controller must be enabled (p1240) and parameterized properly.
• Ramp-down time (p1121) must match inertia of load.
• Required braking power must lie within specified limits.
Note: Regenerative mode can be caused by fast ramp downs or if the motor is driven by an active load.
• r0949 = 0: HW reported
• r0949 = 1 or 2: SW reported
Higher inertia requires longer ramp times; otherwise, apply braking resistor.
F00003 Undervoltage
Reaction: OFF 2
Acknowledge: Quit fault eg. via DI2
Cause: • Main supply failed.
• Shock load outside specified limits.
Remedy: Check Supply voltage (p0210).
Note: • r0949 = 0: HW reported
• r0949 = 1 or 2: SW reported
