[Stroke and Max Speed(Energy-Saving: Disabled)]
Caution
The maximum speed may not be achieved when the stroke or movement distance is
short or when acceleration/deceleration is set 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)
