BYTE unsigned 8−bit integer

ULONG unsigned 32−bit integer, 4 bytes long, with the byte with the lowest value

lowest value of the mantissa first.

3.2.2.78 G234 Direction−dependent height correction

In the case of direction−dependent height correction, the position of the

specified axis is corrected dependent on the driving direction in the current

plane via a grid point table.

G234 AXE K

AXE Identification of the axis, which should be corrected.

0: correction "off"

1: correction "on"

K Parameter field index, from which the correction table is stored in the

P−field.

This function can be used, for example, to correct a Z axis by an offset

dependent on the current driving direction in the XY plane. The correction is

limited to a maximum value of +/−1 input units (e.g. mm or degrees).

With K, the parameter field index is programmed, from which the correction

table is stored in the P field. The first value of the table must contain the

number of the following table values. Every table entry contains a correction

offset for a defined profile angle in the current (time of G234) selected plane.

The table values must cover an angle range of 360°, the first table value

applies to a profile angle of 0°. The table can have a maximum of 36

entries(10° per correction value). The interpolation between the entries is

linear.

The correction is switched off at the end of the program or in the event of a

program termination and by programming G234 without axis letters.

P1200=4 Number of grid points

P1201=0.0 Offset for 0°

P1202=0.1 Offset for 90°

P1203=0.2 Offset for 180°

P1204=0.3 Offset for 270°

G234 Z1 K1200 Correction of the Z−axis "on"

G234 Correction "off"
