• If a large value than deceleration time is set as the rapid stop deceleration time for the parameter block and
positioning data of servo program, a warning will occur. However, writing to the Motion CPU is possible.
■Rapid stop deceleration time  Deceleration time
When the rapid stop cause occurs during deceleration, the axis decelerates to a stop in the rapid stop time.
