9.3 Working area limitation
The "Working area limitation" function can be used to limit the tool traverse
range in all channel axes (e.g. X1, Y1, Z1, C1, AWZ1, SP2 and Z2). These
commands allow you to set up protection zones in the working area which
are out of bounds for tool movements. In this way, you are able to restrict
the traversing range of the axes in addition to the limit switches.
By marking the checkbox "active" the safety area is activated.
9.3.1 Selecting the function "Working area limitation"
Note:
You can only make changes in "AUTO" operating mode when in the
"RESET" condition. These changes are then immediate.
You can make changes in "JOG" operating mode at any time. These
changes, however, only become active at the start of a new motion.
By pressing the VSK 1 "Working area limit." the
"Working area limitation" window opens.

panel, then the HSK 2 "Parameter" to open the oper-
ating area "Parameter". Alternatively press the
"OFFSET"-key on the keyboard.
2. Press the HSK 8 "Setting data".
The "Working area limitation" window opens.
3. Place the cursor in the required field and enter the
new values via the numeric keyboard.
The upper or lower limit of the protection zone
changes according to your inputs.
4. Click the checkbox "active" to activate the protection
zone.
