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.
G90 and G91 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.
