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.
■Rapid stop processing
• Rapid stop during acceleration
When the rapid stop command turns ON during acceleration, acceleration immediately goes to zero, and rapid stop
deceleration processing is executed. (Deceleration is abrupt.)
