Working area limitation

Function
Working area limits describe the area in which machining is possible. They enable the user
to limit the traversing range of the axes in addition to the limit switches.
Reference:
/BP_/ Operation and Programming
A check is made to see whether the tool tip P is within the protected working area. The value
entered for the working area limit is the last permissible position of the axis.
MD21020 WORKAREA_WITH_TOOL_RADIUS (allowance for tool radius with working area
limits) can be set to determine whether the monitor is to take account of the tool radius.
One pair of values (minus/plus) is possible for each axis to describe the protected working
area.
Define working area limits
The working area limits can be defined or changed in two ways:
● Via the operator panel in the "Parameters" operating area using the following setting data:
● In a program with G25/G26. Changes are immediately effective.

SD43430 WORKAREA_LIMIT_MINUS (Working area limitation minus)
SD43420 WORKAREA_LIMIT_PLUS (Working area limitation plus)
Changes during Automatic mode are only possible in the reset state and then take effect
immediately. Changes during JOG mode are always possible, but only take effect with a
new movement.
A programmed motion has priority, it overwrites the value entered in the setting data and
is retained after RESET and End of Program.
