Description
In drive module arg, the DC link voltage is too low for drive unit at unit location arg.
Consequences
No action can be taken until the fault is corrected. The system will go to "Motor Off" state.
Possible causes
The incoming supply voltage to the rectifier unit does not meet specifications.
Recommended actions
- Check for other hardware event log messages regarding supply voltage issues.
- Check the incoming supply voltage. Change the supply tolerance minimum value so that the supply voltage falls within the specified interval.
- Check that the correct voltage is selected using the jumpers on the transformer (optional).
- Check all three-phase components (main switch, mains filter, fuses and contactors) and wiring inside the drive module.
