Description
The surge control resistor in the rectifier unit at drive unit position arg is incorrectly closed.
Consequences
The system goes into a "motor off" state to protect the hardware.
Possible causes
This error occurs when the DC link voltage becomes too low and all phases of the power supply are missing.
Recommended actions
- Check the hardware event log for other errors.
- Check the input supply voltage.
- Check that the correct voltage has been selected using the jumpers on the transformer (optional).
- Check all three-phase components (main switch, mains filter, fuses, contactors) and wiring inside the drive module.
