Positioning Command
When the Command Start Command (C_STRT) is changed from 0 to 1, positioning starts
according to the command code.
If the Hold Command (HOLD) is changed from 0 to 1 during execution of positioning, axis
travel is held. Confirm that the Hold Command has been received by checking that the Hold-
ing Flag (HOLD_R) is set to 1. Change the Hold Command from 1 to 0 to restart the remain-
ing axis travel.
If the Cancel Command (CANCEL) is changed from 0 to 1 during execution of the position-
ing, the moving axis decelerates to stop and the remaining travel distance is discarded. Con-
firm that the Cancel Command has been received by checking that the Progressing Flag
(PRGS) has changed from 1 to 0.
