Precautions for control
• In manual control (JOG operation, inching operation, manual pulse generator operation) and speed-torque control, 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 rapid stop selection" to "[Pr.39] Stop group 3 rapid stop selection" as the stopping method for stop cause
occurrence.
• The stop command processing for deceleration stop function is invalid when "1: Rapid stop" is set in "[Pr.37] Stop group 1
rapid stop selection" to "[Pr.39] Stop group 3 rapid stop selection". (A deceleration curve is re-processed starting from the
speed at stop cause occurrence until at a stop, according to "[Pr.36] Rapid stop deceleration time".) 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] Rapid stop deceleration time" setting.
