If the tool reference point lies outside the working area defined by the working area limitation,
or if this area is exited, then the program sequence is stopped.
Note
If transformations are active, the tool data taken into consideration (tool length and tool radius)
can deviate from the described behavior.
Programmable working area limitation, G25/G26
An upper (G26) and a lower (G25) working area limitation can be defined for each axis. These
values are effective immediately and remain effective for the corresponding MD setting (→
MD10710 $MN_PROG_SD_RESET_SAVE_TAB) after RESET and after being powered-up
again.
Note
Using the predefined CALCPOSI (Page 582) tag function, it can be checked as to whether the
predicted path is moved through taking into account the working area limits and/or the
protection areas.
2.14.3.2 Working area limitation in WCS/SZS (WALCS0 ... WALCS10)
The "working area limitation in WCS/SZS" enables a flexible workpiece-specific limitation of the
traversing range of the channel axes in the workpiece coordinate system (WCS) or settable
zero system (SZS). It is intended mainly for use in conventional lathes.
Requirement
The channel axes must be homed.
Working area limitation group
In order that the axis-specific working area limits do not have to be rewritten for all channel axes
when switching axis assignments, e.g. when switching transformations or the active frame on/
off, working area limitation groups are available.
A working area limitation group comprises the following data:
● Working area limits for all channel axes
● Reference system of the working area limitation
