6.5.6 Pause <
(1) Function
If the pause command is transmitted during movement, the actuator decelerates and stops. If the
status is set back to normal again, the actuator resumes moving for the remaining distance.
As long as the pause command is being transmitted, all motor movement is inhibited.
If the alarm reset command bit is set while the actuator is paused, the remaining travel will be
cancelled.
If this bit is set during home return, the movement command will be held if the actuator has not yet
reversed after contacting the mechanical end. If the actuator has already reversed after contacting
the mechanical end, home return will be repeated from the beginning.
