Deceleration stop
The output axis stops with deceleration according to the setting in "[Pr.37] Stop group 1 rapid stop selection" to "[Pr.39] Stop
group 3 rapid stop selection". The deceleration time set in "[Pr.446] Synchronous control deceleration time" is used for
deceleration stop, and the shorter time set for the rapid stop time between "[Pr.36] Rapid stop deceleration time" and "[Pr.446]
Synchronous control deceleration time" is used for rapid stop. The slope of deceleration is as follows.

Deceleration time (Rapid stop deceleration time)
The cam axis position value per cycle is not updated, and only the command position value is updated when the deceleration
stop begins. Therefore, the path of the command position value is drawn regardless of the cam operation with deceleration
stop.
When decelerating to stop the output axis in synchronization with the input axis, the deceleration stop should be performed to
the input axis.
