Description
The DC link voltage for the power supply unit at unit location arg is too low.
Consequences
No operation is possible until the fault is corrected. The system will go to "Motor Off" state.
Possible causes
The input 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 input supply voltage. Change the supply tolerance minimum value so that the supply voltage falls within the specified interval.
- 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 and contactors) and wiring inside.
