Parameter Description Unit
ZV - only for work offset
write "yes"
Offset Z = 0 (abs)
Workpiece zero is offset in Z direction (inc, the sign is also evaluated)
The workpiece is re-clamped when switching between the main spindle and
counterspindle. The new work offset defines the position for machining at the
machine. However, the simulation must know by which amount the work
offset has shifted with respect to the workpiece, so that both sides of the
machining can be displayed.
