Parameters Details
Control the speed by setting acceleration/deceleration to the speed command inside the
Servo
Drive
.
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
Servo Drive
in combination with
an external position loop. (Set both Pn312 and Pn313 to 0.)
Refer to "6-8 Soft Start (P.6-23)".
Precautions for Correct Use
Do not set the Soft Start Acceleration Time and the Soft Start Deceleration Time when the position
loop structure with a Host Controller is used.
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.
Refer to "6-8 Soft Start (P.6-23)".
