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.
Positioning complete (1) Independent positioning control
(operation pattern: 00)
·
Positioning continue (2) Continuous positioning control
(operation pattern: 01)
(3) Continuous path control
(operation pattern: 11)
·
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.

(One motor is driven, and positioning is carried out to an addresses designated in one direction.)

POINT
When position control of movement amount 0 is executed, the BUSY signal [X4,
X5, X6] also turns ON. However, since the ON time is short, the ON status may not
be detected in the sequence program.
