A gear stage can be defined as follows:
● Permanently by the part program (M41 to M45)
● Automatically by the programmed spindle speed (M40)
M41 to M45:
● The gear stage can be permanently defined in the part program with M41
to M45. If a gear stage is specified using M41 to M45, which is not equal
to the actual (actual) gear stage, then the IS "Change gear stage" and
the IS "Setpoint gear stage" A" to ...C" are set.
M40:
● The control automatically defines the gear stage with M40 in the part
program. The control checks which gear stage is possible for the
programmed spindle speed (S function). If a gear stage is selected that
is not the same as the actual (actual) gear stage, then the IS "Change
gear stage" and the IS "Setpoint gear stage" A" to "...C" are set.
● While the signal = 1, the text "Wait for gear stage change" is displayed
in the channel operating message".

If the actual speed exceeds the max. spindle speed MD35100, by more than
the spindle speed tolerance MD35150, the IS "Speed limit exceeded" is set
and alarm 22050 "Maximum speed reached" is output. All axes and spindles
of the channel are braked.
