Absolute and Incremental Commands (G90, G91)

The amount of axis movement can be expressed by either absolute commands or incremental
commands.
(1) Absolute commands
Designated with G90
Commanded values are coordinate values in the program coordinate system.
When the control is reset, it is in the G90 mode.
(2) Incremental commands
Designated with G91
Commanded values are the travel from the actual position to the target position.
Example:
(Positioning from point (1) to point (2)):
(2)
X100 Z50
X
[Supplement]
1) In incremental programming, the X word should be expressed as a diameter.
2) It is not permissible to specify both G90 and G91 in the same block.
