Changing the spindle speed and feed rate
With the override knobs you can vary the spindle speed S and feed
rate F from 0% to 150% of the set value. However, the range can be
further limited by the machine parameters minFeedOverride,
maxFeedOverride, minSpindleOverride and maxSpindleOverride
(are set by the machine tool builder).
The override dial for spindle speed is only functional on
machines with infinitely variable spindle drive.
The minimum and maximum spindle speeds entered as
machine parameters are not fallen short of or exceeded,
respectively.
If the MP minSpindleOverride=0%, then the setting
spindle override=0 leads to a spindle stop.
