Programmable working area limitation
The activation/deactivation of the programmable working area limitation takes place via the
part program instructions:
• WALIMON (Working area limitation ON)
• WALIMOF (Working area limitation OFF)
Changing the working area limitation
• Working area limitation via setting data
• Programmable working area limitation
Constraints
• The working area limitation refers to the basic coordinate system.
• The working area limitation must lie within the range of the software limit switch.
• PRESET
• The RESET position with regard to WALIMON / WALIMOF is configurable via:
• Endlessly rotating rotary axes

HMI user interface: Operating area "Parameter"
– Automatic modes: Changes are possible only in the RESET state; effectivity:
immediately
– Manual operating modes: Changes are always possible, effectivity: at the start of the
next traversing motion.

Changes are immediately effective.
After use of the function PRESET, the software limit switch monitoring is no longer active.
The machine must first be re-referenced.
MD20150 $MC_GCODE_RESET_VALUES (RESET position of G groups)
No software limit switch monitoring takes place for endlessly rotating rotary axes:
MD30310 $MA_ROT_IS_MODULO == 1 (Modulo conversion for rotary axis and spindle)
