Pn313
Soft Start Deceleration Time
Setting
0 to 10,000
range
Control the speed by setting acceleration/deceleration to the speed command inside the driver.
A soft start can be set when inputting speed commands of stepping movement or when using
internal speed setting.
Do not set acceleration/deceleration time settings when using the driver in combination with an
external position loop. (Set both Pn312 and Pn313 to 0.)

S-curve Acceleration/Deceleration Time Setting
Setting
0 to 1,000
range
Set the pseudo-S-curve acceleration/deceleration value to add to the speed command to enable
smooth operation. This is useful for applications where impact may occur due to a large change
in acceleration or deceleration when starting or stopping with linear acceleration or deceleration.

1 Speed command becomes 0 upon zero speed designation input. (Refer to Figure A)
Speed command becomes 0 upon zero speed designation input, and servo locks with
2 position control when actual speed reaches below Zero Speed Designation Level (Pn316).
(Refer to Figure B)
Servo locks with position control upon zero speed designation input and when speed

1. Basic linear acceleration time and
deceleration time are set by Pn312
and Pn313, respectively.
2. The S-curve time is set by Pn314
(unit: 2 ms) based on the time width

around the point of inflection during
linear acceleration and deceleration.
