Meaning
Measuring axis
Val‐ 1 = 1st axis of the plane (for G18 Z)
ues: 2 = 2nd axis of the plane (for G18 X)
Measuring direction
Val‐ 0 = No selection (measuring direction is determined from actual value)
ues: 1 = Positive
2 = Negative
Offset
Measurement path
Safe area
Variable measuring velocity for calibration
Starting angle when measuring milling tools
Offset angle when measuring milling tools with reversal
Work offset when measuring milling tools. When calibrating S_TZL = 0
Dimensional difference check
Number of measurements at the same location
Number of the empirical mean value memory

Display mode
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)
TENS: Cutting edge position for turning and milling tools
(only for display in the input screens 1 to 9)
HUNDREDS: Tool type
0 = Turning tool
1 = Milling tool
2 = Drill
THOUSANDS: The approach strategy with reference to the tool probe
0 = PLUS [X/Z]; X if tool position axial, Z if tool position radial
1 = MINUS [X/Z]; X if tool position axial, Z if tool position radial
Alternative mode
Val‐ UNITS: Reserved
ues:
TENS: Reserved
HUNDREDS: Reserved
THOUSANDS: approach starting position after measurement for calibration and
single measurement (see S_MVAR - UNITS)
0 = Tool is located, offset by DFA with respect to the probe edge
1 = Approach starting position
