Spindle: Checking the speed controller

Checking the acceleration of the speed controller
The acceleration of the speed controller is checked: The acceleration time must first be
determined without being affected by the NC. Set the following machine data:
● MD35200[0] $MA_GEAR_STEP_SPEEDCTRL_ACCEL = 9999
● MD35200[1] $MA_GEAR_STEP_SPEEDCTRL_ACCEL = 9999
( t=V/a t=9000/60s/9999 t=15 ms, consequently no effect).
