FALSE or parameters not specified:
When evaluating the position and length data, the G code of
group 13 (G70, G71, G700, G710; inch/metric) is evaluated. If
G70 is active and the basic system is metric (or G71 is active
and inch), the WCS system variables $AA_IW[X] and
$AA_MW[X]) are provided in the basic system and must, if
necessary, be reconverted using the CALCPOSI function.
TRUE:
When evaluating the position and length data, the basic
system of the control is always used independent of the value
of the active G of group 13.
Limits to be checked (binary-coded):
1: Monitor software limits
2: Monitor working area limits
3: Monitor activated protection zones
4: Monitor pre-activated protection zones
Combinations by adding the values. Default: 15; check all.
