Common Fault Codes

F001

Overcurrent: Output current has exceeded the permissible limit, typically caused by a short circuit, motor fault, or excessively fast acceleration ramp.
Check motor wiring for short circuits or ground faults. Verify motor parameters are correctly set. Increase acceleration ramp time (P303/P304). Check for mechanical overload on the motor shaft.

F002

Overvoltage: DC bus voltage has exceeded the maximum permissible level, often caused by regenerative energy during deceleration or supply voltage spikes.
Increase deceleration ramp time (P305/P306). Check supply voltage for transient overvoltages. Verify braking resistor or regenerative unit is correctly connected and functioning.

F003

Undervoltage: DC bus voltage has dropped below the minimum permissible level, indicating a supply voltage dip or failure.
Check input supply voltage at all three phases. Verify input fuses and contactors. Investigate supply network for voltage dips or interruptions.

F004

Overtemperature (heatsink): The drive heatsink temperature has exceeded the permissible limit.
Check that cooling fans are operating correctly. Verify ambient temperature is within specification. Clean heatsink fins of dust and debris. Check for adequate ventilation in the cabinet.

F005

Overtemperature (motor): Motor thermal model or PTC/KTY sensor has detected motor overtemperature.
Check motor load and duty cycle. Verify motor cooling (fan operation, ventilation). Check PTC/KTY sensor wiring and connection at the drive. Reduce load or increase motor size if overloading is persistent.

F011

Motor stall / speed deviation: The actual motor speed deviates significantly from the setpoint, indicating a stall condition or encoder fault.
Check encoder wiring and signal integrity. Verify encoder supply voltage. Check for mechanical blockage or excessive load on the motor. Review speed controller parameters (P225, P226).

F023

Ground fault: A ground fault has been detected on the drive output or motor wiring.
Disconnect motor cables and test insulation resistance of motor windings and cables to earth. Replace damaged cables or motor if insulation is compromised.

F041

PROFIBUS communication fault: Communication between the drive and the PROFIBUS master has been interrupted or lost.
Check PROFIBUS cable connections and termination resistors. Verify PROFIBUS address setting on the drive. Check master controller for communication errors. Inspect cable for damage or incorrect shielding.
