3.6.2 Loss of Sync [LOSS_OF_SYNC]

This fault gets triggered when the motor loses synchronization due to improper selection of motor startup and open loop acceleration profiles.

When motor loses synchronization, we might notice the motor either vibrate or stall.

When the motor vibrates, follow the below recommendations.

  1. Increase align time [ALIGN_TIME].

  2. Increase open loop acceleration A1 [OL_ACC_A1] and open loop acceleration A2 [OL_ACC_A2].

When the motor stalls, follow the below recommendation.

Decrease open loop acceleration A1 [OL_ACC_A1] and open loop acceleration A2 [OL_ACC_A2].
