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 sudden stop selection" to "[Pr.39] Stop group 3 sudden stop selection" as the stopping method for stop cause
occurrence.
• The stop command processing for deceleration stop function is invalid when "1: Sudden stop" is set in "[Pr.37] Stop group 1
sudden stop selection" to "[Pr.39] Stop group 3 sudden stop selection". (A deceleration curve is re-processed starting from
the speed at stop cause occurrence until at a stop, according to the "[Pr.36] Sudden 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] Sudden stop deceleration
time" setting.
Setting method
To use the "stop command processing for deceleration stop function", set the following control data in a program.
The set data are made valid as soon as they are written to the buffer memory. The PLC ready signal [Y0] is irrelevant.
Refer to the following for the setting details.
