mm
inch
Work offset Selection of the work offset in which the zero point of the workpiece is saved.
You can also delete the default value of the parameter if you do not want to specify
a work offset.
Write to the work off‐
set
Enter the work offset in the program
● No
The actual Z value of the selected work offset is used.
● Yes
Enter the work offset in the ZV parameter
The actual Z value of the selected work offset is overwritten with the ZV value.
ZV Z value of the work offset of the workpiece mm
