It is possible to define that tool type 0 and tool type 20 are to have the same
effect in the machine data. The radius and tool length compensation are then
assigned in the same way as for type 20. The display for type 0 remains
unchanged.

If the control has been equipped with flexible tool management, the D
numbers are called by the PLC program of the machine manufacturer.
Otherwise, the D numbers have to be specified in the part program as absolute
values (see machine-tool manufacturer's documentation).
With this softkey in the Program Parameters area, you select the input menu
of the zero offsets. Editing is described in the "Editing data in the parameter
area" section.
The actual value memory and thus also the actual value display relate to
machine zero "M" after having reached the reference point.
The workpiece machining program refers to workpiece zero "W". Machine
zero "M" and workpiece zero "W" are not identical. Depending on the type of
workpiece and the way in which it is chucked, the dimension between machine
zero "M" and workpiece zero "W" can vary. This zero offset is taken into
account when the program is executed.
