Cause : START ENABLE 2 MISSING comes when no Start enable 2 signal received. This "Start Enable 2" acts like a digital permission switch, and without it, the drive won't initiate operation.
- Check parameter 1609 START ENABLE 2 settings.
- Check digital input connections.
- Check fieldbus communication settings.
