Display depends on the general SD54760 $SNS_MEA_FUNCTION_MASK_PIECE
1)
Parameters are currently not used and also not displayed in the input screen.
2)
The parameter incremental angle S_INCAis permanently set to 90 degrees.
Value range of starting angle -360 to +360 degrees
3)
for dimensional tolerance yes:
4)
If the measured angle is less than the value of the work offset range TZL, then the result parameters for the angle (_OVR[2],
_OVR[3]) and deviations (_OVR[7], _OVR[8]) are set to zero.
DisplayTZL is realized using the general SD54760 $SNS_MEA_FUNCTION_MASK_PIECE bit25=1.
(enable selected zero offset when measuring angularity, spindle)
Parameter TSA refers to the 1st measurement of the calibration sphere.

Val‐ UNITS: Machining plane G17/G18/G19
ues:
0 = compatibility, the plane active before the cycle call remains active
1 = G17 (only active in the cycle)
2 = G18 (only active in the cycle)
3 = G19 (only active in the cycle)
Alternative mode
Val‐ UNITS: Dimensional tolerance yes/no
ues:
0 = No
