2.14.3 Working area limitation
2.14.3.1 Working area limitation in BCS (G25/G26, WALIMON, WALIMOF)
G25/G26 limits the working area (working field, working space) in which the tool can traverse.
The areas outside the working area limitations defined with G25/G26 are inhibited for any tool
motion.

The working area limitation for all validated axes must be programmed with the WALIMON
command. The WALIMOF command deactivates the working area limitation. WALIMON is the
default setting. Therefore, it only has to be programmed if the working area limitation has been
disabled beforehand.
