Example 2: Axis exchange without synchronization
If the axis does not have to be synchronized no preprocessing stop is generated by GET.

Example 3: Activating an axis exchange without a preprocessing stop
Requirement: Axis replacement without a preprocessing stop must be configured via machine
data.

If the spindle or axis B is traversed, e.g. to 180 degrees and then back to 1 degree immediately
after block N023 as the PLC axis, this axis will revert to its neutral status and will not trigger a
preprocessing stop in block N40.
Further information
Requirements for axis replacement
● The axis must be defined in all channels that use the axis in the machine data.
● It is necessary to define to which channel the axis will be assigned after POWER ON in
the axis-specific machine data.
