12.2.3 Define the second software limit via variables.
The second software limits can only be defined by variables.
On power-up, these variables assume the values of the first software limits. As long as these
variables are not defined with their own value, they copy the values of the first software limits.
Programming of software limits.
Both limits of an axis (lower and upper) may be positive or negative; but the lower limits must
be smaller than the upper ones. When setting both upper and lower limits of an axis to ·0·,
the CNC cancels the second software limit of that axis.
Considerations.
Absolute (G90) or incremental (G91) programming.
The limits defined with variables do not depend on functions G90/G91, they are always in
absolute coordinates and in the machine reference system.
Axes out of position.
If after setting the new limits, an axis positions beyond them, it will be possible to move that
axis towards the work zone (between those limits).
Programming on a lathe (radius/diameter).
The software limits are always defined in radius, regardless of the setting of parameter
DIAMPROG and the active function G151/G152.
Influence of the reset, turning the CNC off and of the M30.
After an M02 or M30 and after an emergency or a reset, the CNC maintains the software
limits set by these variables.
V.A.RTNEGLIMIT.xn Set lower software travel limits (second limit).
V.A.RTPOSLIMIT.xn Set upper software travel limits (second limit).
