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
