Description
In drive module arg, the DC link voltage of drive unit at unit position arg is close to the lower limit.
Consequences
Although it works, there is a high chance that the system will encounter a stop error.
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.
