8.FAULTS WHICH CANNOT BE AUTOMATICALLY RESET
Faults which cannot be automatically reset are listed in the table below. To clear these faults:
1. Remove power from the drive controller.
2. Wait for the display to go off completely.
3. Determine the cause of the fault and correct it.
4. Re-apply power.

PROBABLE CAUSE
• Brake release current not
reached
• Precharge circuit damaged
• Internal fault
• Internal connection fault
• Incorrect parameter settings in
the Set- and drC- menus
• Acceleration too rapid
• Drive controller and/or motor
undersized for load
• Mechanical blockage
• Short circuit or grounding at the
drive controller output
• Significant ground leakage
current at the drive controller
output if several motors are
connected in parallel
• Instability
• Overhauling load
• Motor or motor power not
suitable for the drive controller
• Motor not connected to the drive
controller
• User defined
• Loss of the 4-20 mA reference
on input A13
• Braking too rapidly
• Overhauling load
• Drive controller or ambient
temperature is too high
• Continuous motor current load is
too high
• Check the drive controller and motor
connections
• Check the motor windings
• Reset the drive controller
• Replace the drive controller
• Remove sources of electromagnetic
interference
• Replace the drive controller
• Clear the mechanical blockage
• Check the cable connecting the drive
controller to the motor and check the
motor insulation
• Reduce the switching frequency
• Check the size of the motor, drive
controller, and load
• Check the presence of the motor during
auto-tuning
• If a downstream contractor is being used,
close it during auto-tuning
• User defined
• Check the connection on input A13
• Loss of 4-20 mA follower
• Increase the deceleration time
• Check the motor load, the drive controller
ventilation, and the environment. Wait for
the drive controller to cool before
restarting
