Measuring result display
0: OFF
1: ON
Acknowledgment measurement result screen with NC start
0: OFF (If _CHBIT[18]=0, the display is automatically
deselected at end of cycle.)
1: ON (M0 is generated in the cycle.)
currently not assigned
Coupling spindle position with coordinate rotation in active plane
for workpiece measurement with multi probe
0: OFF
1: ON
Adapt spindle positioning, if _CHBIT[13]=1
0: Following standard
1: adapted angle values
Number of measurements on failure to switch
0: up to 5 measurements
1: only 1 measurement
Retraction velocity from the measuring point
0: velocity as for intermediate positioning
1: with percentage of rapid traverse velocity (_SPEED[0])
(only active with collision monitoring ON: _CHBIT[2]=1)
Feed during measurement
0: with feed in _VMS
1: During 1st measurement feed in _SPEED[3]
During 2nd measurement with feed in _VMS
Static measurement result display
0: effect as set in _CHBIT[11]
1: only active if _CHBIT[11]=0: Measuring result display remains
until next measuring cycle is called
Only active for CYCLE974 or CYCLE994!
Special treatment of Y axis with G18
0: No special treatment
1: setpoint setting and parameterization (_SETVAL, _TUL,
_TLL, SZO) for the Y axis (applicate) as for the parameterization
of the ordinate (X axis). The tool offset is applied in the length
that is active in the ordinate (X axis) (usually L1), as long as no
other length has been set in _KNUM. The ZO compensation is
applied in the specified ZO memory in the ordinate component
(X axis).
Only active for CYCLE982!
Measuring milling tools
Suppression of the starting angle positioning _STA1
0: suppression OFF
1: suppression ON
