schneider drive fault codes nst indicates the drive is in freewheel stop mode. This means NST is not a fault but rather a status indicating the drive is in a freewheel stop condition.
To troubleshoot the NST error code, you can try these steps:
- Check the freewheel stop assignment.
- Check the state of any digital inputs.
- Cycle drive power to clear it.
- Check if a run command is present when power is applied to the drive.
- Check if drive is in a Network setting and the parameter Control Mode [CHCF] is set to Separate or Not Separate.
- Check 4-20mA Loss setting and see if it's set to freewheel stop.
