(2) L system
When axis coordinate data is issued in a machining program command, either the incremental
command method that commands a relative distance from the current position or the absolute
command method that moves to a designated position in a predetermined coordinate system can be
selected.
When issuing an incremental command, register the axis address to be commanded as the incremental
axis name in the parameter. However, the arc radius designation (R) and arc center designation (I, J, K)
always use incremental designations.
Absolute command (absolute command) ... X, Z
Incremental command (incremental command) ... U, W

The above drawing shows the case for the diameter command.
(Note)
Absolute command and incremental command can be switched by the parameter. In addition to the
command method using the axis addresses as indicated above, a command method using G code
(G90/G91) may be selected.
