Common Fault Codes

Fault Code F002

Auxiliary Input fault. The auxiliary input interlock has been opened or a digital input configured as an enable signal is not active.
Check the wiring and status of the auxiliary input or enable digital input. Verify that any external interlock devices are closed and the signal is present at the configured terminal.

Fault Code F003

Power Loss fault. The drive detected a loss of input AC power or an input phase loss condition.
Check incoming AC supply voltage on all three phases. Inspect input fuses, wiring connections, and upstream contactors or circuit breakers for open circuits or loose terminals.

Fault Code F004

Undervoltage fault. The DC bus voltage has dropped below the minimum threshold, typically caused by low input voltage or a momentary power dip.
Measure input line voltage and verify it is within the drive's rated input range. Check for voltage sags on the supply and inspect input wiring for high resistance connections.

Fault Code F005

Overvoltage fault. The DC bus voltage has exceeded the maximum allowable level, often caused by regenerative energy from a decelerating load.
Increase the deceleration ramp time to reduce regenerative energy. If the application requires fast deceleration, install a dynamic braking resistor and enable the braking chopper function.

Fault Code F006

Motor Stall fault. The drive has detected that the motor current has exceeded the stall current threshold for longer than the programmed stall time.
Check the mechanical load for jams or excessive friction. Verify motor nameplate data is correctly entered in drive parameters. Adjust stall current and stall time parameters if necessary.

Fault Code F007

Motor Overload fault. The electronic motor overload protection has tripped due to sustained overcurrent, indicating the motor is being operated beyond its thermal capacity.
Reduce the load on the motor or increase the deceleration/acceleration times. Verify motor FLA is correctly programmed. Allow the motor to cool before restarting and investigate the cause of overloading.

Fault Code F012

HW OverCurrent fault. The drive output current has exceeded the hardware overcurrent trip level, which may indicate a short circuit at the output, a ground fault, or a motor winding fault.
Disconnect the motor and check for short circuits between output phases and between phases and ground. Inspect motor winding insulation resistance. Check for damaged output wiring before restarting.

Fault Code F033

Safe Torque Off (STO) fault. The STO input signal has been removed or the STO circuit has detected a wiring fault, disabling drive output.
Verify that the STO input wiring is intact and that the safety circuit is providing the correct 24V DC signal to the STO terminals. Check for broken wires or faulty safety relay contacts in the STO loop.
