spindle Oscillation mode
主轴摆动功能，往往应用于主轴换档的时候。以下复制了一些关于该信号的描述和模式的切换，希望对楼主有帮助。
Open-loop control mode → Oscillation mode
The spindle changes to oscillation mode if a new gear step 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 → Open-loop control mode
When the new gear is engaged, IS:
DB31, ... DBX84.6 (Oscillation mode)
is reset and the spindle is switched
to open-loop control mode with IS:
DB31, ... DBX16.3 (Gear changed).
The last programmed spindle speed (S value) is reactivated.
• Positioning mode → Oscillation mode
If the orientation of the spindle is to be terminated, M41 to M45 can be used to change to
oscillation mode. When the gear change is complete, the last programmed spindle speed
(S value) and M5 (control mode) are reactivated.
• Axis mode → Oscillation mode
To terminate axis mode, M41 to M45 can be used to change to oscillation mode (only if
the programmed gear step is not the same as the actual gear step). When the gear
change is complete, the last programmed spindle speed (S value) and M5 (control mode)
are reactivated.
