Drive does not start, display off:

Check that line voltage is present at the drive terminals
Unplug all the connections on the drive U, V, W terminals and check that there is no short circuit
between the phase and earth in the motor wiring or in the motor.

Faults which cannot be reset automatically:

The cause of the fault must be removed before resetting by switching power off and on again.

FAULT PROBABLE

CAUSE

REMEDY

CFF

Configuration fault

• The

current

configuration is
inconsistent

• Return to factory settings and re-enter

parameters

CrF

Capacitor charging
circuit

• Load relay control fault

or charging resistor
damaged

• Replace the drive

InF

Internal fault

• Internal

fault

• Check the environment

(electromagnetic compatibility)

• Replace

drive

OCF

Overcurrent

• Ramp to short

• Inertia or load too high

• Mechanical

locking

• Check the settings

• Check the size of the motor/drive/load

• Check the state of the mechanism

SCF

Motor short-circuit

• Insulation fault or short-

circuit at the drive
output

• Check the cables connecting the drive

to the motor, and the motor insulation

SOF

Overspeed

• Instability or driving load

too high

• Check the motor, gain and stability

parameters

• Add a breaking resistor and module

• Check the size of the motor/drive/load
