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.
The setpoint gear stage is output in coded format:
1. Gear stage
1st gear stage
2nd gear stage
3rd gear stage
4th gear stage
5th gear stage
