Faults which can be reset with automatic restart function, after the cause of the fault disappeared:

These faults can also be reset by switching the drive off and on again.

FAULT PROBABLE

CAUSE

REMEDY

ObF

Overvoltage during
deceleration

• Braking too sudden or

driving load

• Increase the deceleration time

• Install a braking module and a braking

resistor if necessary

• Activate the brA function if it is

compatible with the application

OHF

Drive over
temperature

• Drive temperature too

high

• Sheck the motor load, the drive

ventilation and the environment. Wait
for the drive to cool down before
restarting

OLF

Motor overload

• Trigger by motor current

too high

• Check the setting of the motor thermal

protection, check the motor load. Wait
for the motor to cool down before
restarting

OSF

Overvoltage

• Line voltage too high

• Disturbed line supply

• Check the line voltage. The

overvoltage threshold is 415VDC on
the DC bus

PHF

Line phase failure

• Dive

incorrectly

supplied of blown circuit
protection

• Failure of one phase

• Check the power connections and the

circuit protection

• Reset

Faults which can be reset as soon as its cause disappears:

FAULT PROBABLE

CAUSE

REMEDY

USF

Undervoltage

• Line supply too low

• Transient voltage dip

• Damaged load resistor

• Check the voltage and the voltage

parameter. The undervoltage
threshold is 230vDC on the DC bus

• Replace the drive
