Caution
The maximum speed may not be achieved when the stroke or movement distance is
short or when acceleration/deceleration is low.
Setting at or below the minimum speed may lead to abnormal noise or unstable speeds.
The minimum speed can be calculated with the equation below.
Minimum speed [mm/s] = ball screw lead [mm/r] ÷ 800 [p/r] x 1000 [1/s]
(mm/r: movement per 1 motor revolution, p/r: pulse per 1 motor revolution)
