Spindle speed limitation: G25, G26

Functionality
In the program, you can limit the limit values that would otherwise apply by writing G25 or
G26 and the spindle address S with the speed limit value. At the same time the values in the
setting data are overwritten.
G25 or G26 only need one separate block each. A previously programmed speed S is
maintained.

programmed/entered.
