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.
