Example
3 axes are defined in the channel: X, Y and Z
A working area limitation group No. 2 is to be defined and then activated in which the axes
are to be limited in the WCS acc. to the following specifications:
• X axis in the plus direction: 10 mm
• X axis in the minus direction: No limitation
• Y axis in the plus direction: 34 mm
• Y axis in the minus direction: -25 mm
• Z axis in the plus direction: No limitation
• Z axis in the minus direction: -600 mm

Description
Effectivity
The working area limitation with WALCS1 - WALCS10 acts independently of the working area
limitation with WALIMON. If both functions are active, that limit becomes effective which the
axis motion first reaches.
Reference point at the tool
Taking into account the tool data (tool length and tool radius) and therefore the reference
point at the tool when monitoring the working area limitation corresponds to the behavior for
the working area limitation with WALIMON.
