But When I use function "MC_MoveRelative" tolet motor running, I observe one situation. Motor occur "overshooting" when it start and stop running. My speed setpoint value is 120 RPM, but actual speed value that it's over 120 rpm when motor start and stop running. Does here anyone can tell me which parameters in S120 can improve or adjust this situation? Attachment overshoot_1.zip (434 Downloads)
