Description
The resistance of the bleeder resistor connected to the rectifier unit at drive unit position arg is too high (open circuit).
Consequences
No operation is possible until the fault is corrected. The system will go to "Motor Off" state. Hazardous High Voltage: When the system is powered off, the DC link may not be discharged.
Possible causes
This may be caused by a fault in the bleeder resistor or its wiring.
Recommended actions
Dangerously high voltages may be present.
- Make sure the bleeder resistor cable is correctly connected to the rectifier unit.
- Disconnect the bleeder, check the cable and measure the bleeder resistance value. Expect the resistor value to be around ohms.
