12.23.3 Functional description

• At the end of a program (or after reset), the last active ZO group (G54 - G57) and

TO (D0 - D819) are retained. The actual-value display is merely adjusted by the

programmable offsets (G58 and G59).

• When the function is deactivated (SD 5001, bit 0 = 0), all actual values displays are

updated according to actual-value representation for the machine.

12.23.4 Example of function

For reasons of simplicity, this example refers only to two axes of the 1st channel. In the

example, the X axis is the abscissa and the Y axis the ordinate (see MD 1100, 5480, 5500 and

5520).

Default settings:

SD 5001.0 = 1 ; "Actual-value display for workpiece" function active

NC MD5153.1 = 0 ; After NC start, reset position ZO from MD 1120 = G54 and TO

= D0 active.

NC MD1100 = 17 ; Plane G17 (X abscissa and Y ordinate) has been selected in the

1st channel to define the reference for tool offsets during

machining.

NC MD5480 = 0000 ; (address name X abscissa)

NC MD5500 = 0001 ; (address name Y ordinate)

NC MD5520 = 0010 ; (address name Z co-ordinate), the plane names of the co-ordinate

system are assigned to the axes listed above in the 1st channel.

Table: ZO data referring to example

Active TO = D3 (type = 1, a tool with 2 length compensations and tool nose radius

compensation)

L1 Geometry P2=-90 L2 Geometry P3=-180

L1 Wear P5=-9 L2 Wear P6=-18

L1 Basis P8=-1 L2 Basis P8=-2

Note regarding tool compensation:

L1 always refers to the ordinate and L2 to the abscissa of the co-ordinate system. The

assignment between the TO and the axes can be changed in the NC program by means of

plane selection.
