Soft Start Function
This function sets the acceleration and deceleration against the velocity command input inside the
Servo Drive and uses these values for speed control.
With this function, soft starts are possible when the step rotation velocity commands are input. To
reduce any impacts made by acceleration changes, you can also use the velocity command filter
(first-order lag).
For a step velocity command input, set the time until the velocity command reaches 1,000 r/min in
Acceleration Time.
Similarly, set the time until the velocity command slows from 1,000 r/min down to 0 r/min in Decelera-
tion Time.
Acceleration Time (ms) = Vc/1,000 r/min × Acceleration Time × 0.1 ms
Deceleration Time (ms) = Vc/1,000 r/min × Deceleration Time × 0.1 ms
