Mode change

Switching between spindle and axis operation can be done as follows:
• Control mode → Oscillation mode
The spindle changes to oscillation mode if a new gear stage has been specified using automatic gear step
selection (M40) in conjunction with a new S value or by M41 to M45. The spindle only changes to oscillation
mode if the new gear step is not equal to the current actual gear step.
• Oscillation mode → Control mode
When the new gear is engaged, the interface signal:
DB31, ... DBX84.6 (Oscillation mode)
is reset and the interface signal:
DB31, ... DBX16.3 (Gear changed)
