4 PARAMETERS FOR POSITIONING CONTROL
[Operation]
(1) Stop processing
When the stop command turns ON during acceleration, the acceleration is
decreased until it reaches zero according to acceleration section 2 ratio setting.
Therefore, the speed will continue to increase for a while before deceleration stop
processing is executed.
(Deceleration is smooth.)

POINTS
When the stop command turns ON during acceleration processing of advanced S-
curve acceleration/deceleration, in order to maintain smoothness of acceleration,
the speed will continue to increase until acceleration reaches zero.
Use the rapid stop command if an increase in speed is not desired.
