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 
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. 
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 
After use of the function PRESET, the software limit switch monitoring is no longer active. 
The machine must first be re-referenced. 
•  The RESET position with regard to WALIMON / WALIMOF is configurable via: 
MD20150 $MC_GCODE_RESET_VALUES (RESET position of G groups)  
•  Endlessly rotating rotary axes 
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)
