Chapter 13 Control Sub Functions
(2) Deceleration curve continuation
The current deceleration curve is continued after a stop cause has occurred.
If a stop cause occurs during automatic deceleration of position control, the
deceleration stop processing may be complete before the target has
reached the positioning address specified in the positioning data that is
currently executed.

[2] Precautions for control
(1) 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.
(2) 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.
(3) 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.
