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 is set in "[Pr.446] Synchronous control deceleration time" for deceleration
stop, and in "[Pr.36] Rapid stop deceleration time" for rapid stop. The slope of deceleration is as follows.
Slope of deceleration
The cam axis current value per cycle is not updated, and only the feed current value is updated, since the deceleration stop
begins. Therefore, the path of the feed current value is drawn regardless the cam operation with deceleration stop.
The input axis must be stopped when the output axis is stop synchronizing with the input axis.
