Troubleshooting and error codes

Fault/Warning	Cause	Remedy
Overvoltage	Motor speed exceeds rated speed	Do not run the motor over the rated speed.
Overheating (resistor)	Brake chopper not enabled or improper parameter settings	Ensure the brake chopper is enabled via parameter setting. Set parameter 95.07 LCU DC REF (V) to the minimum (default) value. Consult an ABB representative for brake resistor overload protection parameters.
Equipment malfunction/damage (Fiber-optic cables)	Improper handling of fiber-optic cables	Handle with care, hold the connector, not the cable. Do not touch fiber ends. Maintain minimum bend radius of 35 mm.
Damage/faults (Printed circuit boards)	Electrostatic discharge	Use an ESD wrist band when touching printed circuit boards. Do not touch unnecessarily.
Serious injury/death or equipment damage	Ignoring safety instructions during installation/maintenance	Only qualified electricians should perform work. Disconnect power and wait 5 minutes for capacitors to discharge. Verify voltages are zero before proceeding.
