3.2 Determining the coordinate value input modes

3.2 Determining the coordinate value input modes
This section describes the commands used to input coordinate values.
3.2.1

Absolute/incremental designation

Axis movement data specified following an axis address determines axis move-
ment distance in either incremental or absolute values.
By using addresses X, Z, C, Y, U, W, H, and V, it is possible to use both incremen-
tal and absolute values.
Command format
S Absolute commands
To specify axis movement distance in an absolute value, use addresses X, Z,
and C.
Example:
S Incremental commands
To specify axis movement distance in an incremental value, use addresses U,
W, and H.
Example:
S Use of both incremental and absolute commands in the same block
It is allowed to use both incremental and absolute values in the same block.
Example:
If addresses that represent the same axis are specified in the same block like
"X... U... ;", the address specified later becomes valid.
These G codes specify whether dimension values specified following an axis
address are given in an absolute value or incremental value.
