Order of priority for the stop processing
The order of priority for the positioning module stop processing is as described below.
(Deceleration stop) < (Sudden stop) < (Immediate stop)
If the deceleration stop command is ON (i.e., the stop signal is ON) or a deceleration stop cause occurs during the
deceleration to speed 0 (including automatic deceleration), the operation changes depending on the setting in [Cd.42] Stop
command processing for deceleration stop selection. (Page 267 Stop command processing for deceleration stop
function)

Manual control
OPR control, positioning control
If the on state of the stop signal or stop cause specified for a sudden stop occurs is detected during deceleration, the sudden
stop processing will start at that point. However, if the sudden stop deceleration time is longer than the deceleration time, the
deceleration stop processing will be continued even if a sudden stop cause occurs during the deceleration stop processing.
[E.g.] The processing if a sudden stop factor is input during deceleration to stop is described below.
• If deceleration stop time> Sudden stop deceleration time

Processing
Regardless of the setting of "[Cd.42] Stop command processing for
deceleration stop selection", a deceleration curve is re-processed from the
speed at the occurrence of a stop cause.
Recreates the deceleration curve from the speed when the stop factors
occurred. (Page 267 Deceleration curve re-processing)
The current deceleration curve is maintained after the occurrence of a stop
cause. (Page 267 Deceleration curve continuation)
