With a step speed command, the speed command can be changed based on the setting to reduce the
shock caused by change in acceleration.
Soft Start Acceleration Time (Pn312) and Soft Start Deceleration Time
(Pn313)
For a step speed command input, set the time until the command speed reaches 1
,000
r/min in Soft
Start Acceleration Time (Pn312). Similarly, set the time until the command speed slows from 1,000
r/min down to 0 r/min in Soft Start Deceleration Time (Pn313).
Soft Start Acceleration Time [ms] = Vc/1,000 x Pn312 x 1 ms
Soft Start Deceleration Time [ms] = Vc/1,000 x Pn313 x 1 ms
