Description
The resistance of the power supply unit at drive unit location arg is too high (open circuit).
Consequences
No operation is possible until the fault is corrected. The system will go to "Motor Off" state.
Possible causes
This may be caused by a faulty bleeder resistor or its cable.
Recommended actions
- Make sure the bleeder resistor cable is correctly connected to the rectifier unit.
- Disconnect the bleeder resistor, check the cable and measure the bleeder resistor value.
