Absolute positioning specifies the absolute coordinates of the target position in relation to home. You
can perform positioning, such as shortest way positioning on a rotary table, by setting the Count Mode
to Rotary Mode and specifying the operation direction.
For details, refer to the MC_MoveAbsolute (Absolute Positioning) and MC_Move (Positioning) instruc-
tions in the NJ/NX-series Motion Control Instructions Reference Manual (Cat. No. W508).
Relative positioning specifies the distance from the actual position. You can specify a travel distance
that exceeds the ring counter range by setting the Count Mode to Rotary Mode.
For details, refer to the MC_MoveRelative (Relative Positioning) and MC_Move (Positioning) instruc-
tions in the NJ/NX-series Motion Control Instructions Reference Manual (Cat. No. W508).
