9 MAIN POSITIONING CONTROL
9.1.2 Operation patterns of main positioning controls
In "main positioning control" (advanced positioning control), "
Da.1 Operation
pattern" can be set to designate whether to continue executing positioning data after
the started positioning data. The "operation pattern" includes the following 3 types.
the started positioning data. The "operation pattern" includes the following 3 types.
Positioning complete
(1) Independent positioning control
(operation pattern: 00)
(operation pattern: 00)

Positioning continue
(2) Continuous positioning control
(operation pattern: 01)
(3) Continuous path control

The following shows examples of operation patterns when "1-axis linear control (ABS
linear 1)" is set in positioning data No. 1 to No. 6 of axis 1. Details of each operation
pattern are shown on the following pages.

When position control of movement amount 0 is executed, the BUSY signal [RXn4,
RXn5] also turns ON. However, since the ON time is short, the ON status may not
be detected in the sequence program.
