Explanation of example
Automatic compensation is performed in G55, offset in X and Y by the calculated difference
between the actual value and set position of the groove center point, should it be less than 1
mm (_TSA) in both axes. Otherwise, alarm "Safe area violated" is output and program
execution cannot be continued. It must be interrupted with NC RESET.
The corrected ZO G55 is activated in block N90.
The results are entered in result array _OVR[ ].

;ZO, select tool as probe ...
;Insert probe,
;activate tool offset
;Position probe in X/Y plane
;in setpoint center
;Position probe at measuring height
;Set parameters for measuring cycle call
;Call measuring cycle for ZO
;determination in X/Y plane
;Traverse up Z axis
;Repeat call of zero offset G55
;The changes thereby take effect!
