Overview
The G17, G18, and G19 modal instructions are used to congure the main plane of the current motion
control coordinate system as the XY plane, YZ plane, or ZX plane. They are mainly used for arc and helix
interpolation.

Functions and actions
Current running of a motion control subprogram means that the subprogram is always in running state after
the SM90 enabling ag is active. The current running is nished when the SM91 complete ag switches
to ON. If the subprogram calls another motion control subprogram, the called subprogram is also within
the current running scope. The modal instruction enabled in the current running remains active until the
execution is completed or changed.
After being started, the motion control subprogram is executed in the default modal, and is always active
when the current modal remains unchanged.
G17, G18, and G19 are mutually exclusive modal instructions. The current modal remains unchanged after
being enabled until another modal is enabled. The default modal is in absolute position mode on the XY
plane.
