1)
Display depends on the general SD 54760 $SNS_MEA_FUNCTION_MASK_PIECE
2)
Only relevant for calibration in two axis directions
3)
Only measuring axis and measuring direction are determined automatically from the cutting edge position (SL) of the probe.
4)
SL=8 → -X , SL=7 → -Z
The number of the calibration groove (n) refers to the following general setting data (all positions in machine coordinate

system):
For cutting edge SL=7:
SD54615 $SNS_MEA_CAL_EDGE_BASE_AX1[n] Position base of the groove in the 1st axis of the plane (for G18 Z)
SD54621 $SNS_MEA_CAL_EDGE_PLUS_DIR_AX2[n] Position of the groove wall in the positive direction of the 2nd axis
of the plane (for G18 X)
SD54622 $SNS_MEA_CAL_EDGE_MINUS_DIR_AX2[n] Position of the groove wall in the negative direction of the 2nd axis
of the plane
for cutting edge position SL=8:
SD54619 $SNS_MEA_CAL_EDGE_BASE_AX2[n] Position of the groove base in the 2nd axis of the plane
SD54620 $SNS_MEA_CAL_EDGE_UPPER_AX2[n] Position of the upper edge of the groove in the 2nd axis of the plane
(only to preposition the probe)
SD54617 $SNS_MEA_CAL_EDGE_PLUS_DIR_AX1[n] Position of the groove wall in the positive direction of the 1st axis
of the plane
SD54618 $SNS_MEA_CAL_EDGE_MINUS_DIR_AX1[n] Position of the groove wall in the negative direction of the 1st axis
of the plane
Note:
The positions values for the groove wall +- can be determined roughly.

Meaning
Number of the field of the probe parameters (not probe number)
(default=1)
Setpoint for calibration on a surface
Measuring axis (number of the axis)
Val‐ 1 = 1st axis of the plane (for G18 Z)
ues: 2 = 2nd axis of the plane (for G18 X)
3 = 3rd axis of the plane (for G18 Y)
Measuring direction (default=1)
Val‐ 0 = Positive measuring direction
ues: 1 = Negative measuring direction
Measurement path
Safe area
Variable measuring velocity for calibration
Number of measurements at the same location

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)
