Description
Contact arg of drive unit has reached the maximum output voltage. Contacts are connected to drive unit arg where drive unit is located at unit position arg and node arg.
Consequences
The system enters the "motor off" state
Possible causes
- The motor is not properly connected to the drive unit.
- The motor data in the configuration is incorrect.
- DC link voltage too low.
- A short circuit occurs between motor phases or to ground.
Recommended actions
- Check motor cables and connectors.
- Check the motor parameter configuration.
- Check for other hardware event log messages.
- Check the voltage of the rectifier unit input power supply.
- Perform the check by measuring the resistance of the motor and its cables respectively. Disconnect before taking measurements.
