: Refer to Section 5.2 "List of parameters" for setting details.
The "acceleration/deceleration processing function" adjusts the
acceleration/deceleration of each control to the acceleration/deceleration curve
suitable for device.
Setting the acceleration/deceleration time changes the slope of the
acceleration/deceleration curve.
The following two methods can be selected for the acceleration/deceleration curve:
 Trapezoidal acceleration/deceleration

S-curve acceleration/deceleration
Refer to Section 12.1 "Speed-torque control" for acceleration/deceleration processing
of speed-torque control.
The details shown below explain about the "acceleration/deceleration processing
function".

In the Simple Motion module, four types each of acceleration time and
deceleration time can be set. By using separate acceleration/deceleration times,
control can be carried out with different acceleration/deceleration times for
positioning control, JOG operation, HPR, etc.
Set the required values for the acceleration/deceleration time in the parameters
shown in the following table, and write them to the Simple Motion module.
The set details are validated when written to the Simple Motion module.
