Description of the most important defining parameters

2.3
2.3.1

Measurement variant: _MVAR

Parameter
The measuring variant of each individual cycle is defined in parameter _MVAR. _MVAR can
be assigned certain positive integer values.
Please refer to the individual cycle descriptions!
Note
Validity
The value in _MVAR is plausibility checked by the cycle. If it does not have a defined value,
alarm 61307 is output: "Incorrect measuring variant".
The cycle must be interrupted by an NC RESET. _MVAR must be corrected.
2.3.2

Number of the measuring axis: _MA

Parameter
In some cycles or measuring variants, number 1, 2, or 3 must be specified in _MA for the
measuring axis. This might by axis X, Y, or Z in the workpiece coordinate system depending
on whether G17, G18, or G19 is active.
This always results in:
Measuring axis,
abscissa
Measuring axis,
ordinate
Measuring axis,
applicate
Example:
Workpiece measurement on milling
machine with G17, various measuring
directions
