To confirm that the servomotor moved 100 mm, do a visual check orcheck the feedback pulse counter (Un00D [pulse])Note: If the movement of the servomotor is not correct, check the reference sent bythe host controller.8.1 List of Monitor Dis-plays8 Return the speed reference input to 0 V. 9 Turn OFF the servo ON signal (/S-ON).
