Soft Start

This function performs auto acceleration and deceleration inside the Servo Drive when step-type veloc-
ity commands are input.
To reduce any impacts made by acceleration changes, you can also use the velocity command
first-order lag filter.

Soft Start Acceleration/Deceleration Time

For a step velocity command input, set the time required for the velocity command to reach 1,000 r/min
in Acceleration Time.
Similarly, set the time required for the velocity command to decrease the velocity from 1,000 r/min to 0
r/min in Deceleration 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
Velocity command [r/min]
1,000 [r/min]
