Cause : Synchron fault comes when difference in actual position of Master drive and drive. For example, value in parameter 82.20 Act position error is more than the limit defined in parameter 82.7 Sync err limit and the condition prevails for more than the delay time set in parameter 82.08 Sync err fault delay.

D10B "Synchron fault" fault in ABB ACS880 drive indicate that difference in actual position of Master drive and drive.

1. Check the limit set for position difference in parameter 82.7 Sync err limit.
2. Check the delay time set in parameter 82.08 Sync err fault delay.
3. Check the position correction parameters: 82.4 Sync gain, 82.5 Position corr limit, and 82.6 Sync corr scale.
