Axis replacement with and without preprocessing stop

Axis replacement extension without preprocessing stop
Instead of a GET block with a preprocessing stop, this GET request only generates an
intermediate block. In the main run, when this block is executed, the system checks whether
the states of the axes in the block match the current axis states. If they do not match, forced
reorganization can be triggered.
The following states of an axis or positioned spindle are checked for:
● The mode, either for the axis or for positioned spindle
● Setpoint position
The following states of a Spindle in speed mode are checked:
● Spindle mode: Speed mode
● Spindle speed S
● Direction of rotation M3, M4
● Gear stage M40, M41, M42, M43, M44, M45
● Master spindle at constant cutting rate.
In some instances, forced reorganization may be possible. Reorganization of the following
axes is forced in any case.
Activation
Replacement without preprocessing and checking of the current states is activated with
machine data MD10722 $MN_AXCHANGE_MASK, Bit 2=1.
