6.4 CYCLE973 Calibrating workpiece probes
The workpiece probe calibrated is selected with _PRNUM. The associated array _WP[ ] in
data block GUD6.DEF is _WP[_PRNUM-1,...] (for a detailed description of the array, refer to
Chapter "Data description", "Central values").
The reference groove is selected with _CALNUM. The associated array _KB[ ] in data block
GUD6.DEF is _KB[_CALNUM-1,...].
Prerequisite
The dimensions of the reference groove must already be stored in array _KB[ ] of data block
GUD6.DEF for the groove selected via _CALNUM.
The workpiece probe must be called as a tool with a tool offset.

_CALNUM
_PRNUM
Additional parameters _VMS, _TZL, _TSA, _FA and _NMSP also apply.
Note
When _MVAR=x1x13 calibration is only performed in one direction. It is not possible to
determine position deviation or calculate probe ball.
NOTICE
The first time calibration is performed the default setting in the array of the probe is still "0".
For that reason _TSA> probe ball radius must be programmed to avoid alarm "Safe area
violated".
