4 Spindle
8/95
Machine parameters MP7130 and MP7140 were introduced so that the spindle ramp for tapping
could be better adjusted to the dynamic characteristics of the machine. Machine parameter MP7150
fixes the positioning window for the tool axis. The input value must be less than or equal to
MP1030.2.
A spindle overshoot when accelerating and running into position must be avoided at all costs.
