(b) Deceleration curve continuation
The current deceleration curve is continued after a stop cause has occurred.
If a stop cause occurs during automatic deceleration of position control, the deceleration stop processing may
be complete before the target has reached the positioning address specified in the positioning data that is
currently executed.

(2) Control precautions
• In manual control (JOG operation, inching operation, manual pulse generator operation), the stop command
processing for deceleration stop function is invalid.
• The stop command processing for deceleration stop function is valid when "0: Normal deceleration stop" is
set in "[Pr.37] Stop group 1 sudden stop selection" to "[Pr.39] Stop group 3 sudden stop selection" as the
stopping method for stop cause occurrence.
• The stop command processing for deceleration stop function is invalid when "1: Sudden stop" is set in
"[Pr.37] Stop group 1 sudden stop selection" to "[Pr.39] Stop group 3 sudden stop selection". (A deceleration
curve is re-processed, according to the "[Pr.36] Sudden stop deceleration time" (starting from the speed at
stop cause occurrence to a stop))
In the position control (including position control of speed/position changeover control or position/speed
changeover control) mode, positioning may stop immediately depending on the stop cause occurrence
timing and "[Pr.36] Sudden stop deceleration time" setting.
