Fault code list
Fault
Cause
Remedy
F1
Overcurrent
•
Motor power (P0307) does not
correspond to the inverter power
(r0206).
•
Motor lead short circuit
•
Earth faults
r0949 = 0: Hardware reported
r0949 = 1: Software reported
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)
F2
Overvoltage
•
Main supply voltage too high
•
Motor is in regenerative mode
r0949 = 0: Hardware reported
r0949 = 1 or 2: Software reported
Check the following:
•
Supply voltage (P0210) must lie within limits
indicated on rating plate.
•
Ramp-down time (P1121) must match inertia of
load.
•
Required braking power must lie within specified
limits.
•
Vdc controller must be enabled (P1240) and
parameterized properly.
Note:
Regenerative mode can be caused by fast ramp
downs or if the motor is driven by an active load.
Higher inertia requires longer ramp times;
otherwise, apply braking resistor.
F3
Undervoltage
•
Main supply failed.
•
Shock load outside specified limits.
r0949 = 0: Hardware reported
r0949 = 1 or 2: Software reported
Check supply voltage.
F4
Inverter overtemperature
•
Inverter overloaded
•
Ventilation inadequate
•
Pulse frequency too high
•
Ambient temperature too high
•
Fan inoperative
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
F5
Inverter I
2
t
•
Inverter overloaded.
•
Load cycle too demanding.
•
Motor power (P0307) exceeds
inverter power capability (r0206).
Check the following:
•
Load cycle must lie within specified limits.
•
Motor power (P0307) must match inverter power
(r0206)
