Operation patterns of major positioning controls
In "major positioning control" (high-level 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 ((1) to (3)).
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.
The BUSY signal [XC, XD, XE, XF] turns ON even when position control of movement amount 0 is executed. However, since
the ON time is short, the ON status may not be detected in the program.
• Positioning complete
(1) Independent positioning control
(operation pattern: 00)
• Positioning continue
(3) Continuous path control
(operation pattern: 11)
(2) Continuous positioning control
(operation pattern: 01)
< Operation example when "1-axis linear positioning" is set in the positioning data of axis 1 >
(Direction in which axis 1 addresses increase)
1-axis linear control
(One motor is driven, and positioning is carried out to an addresses designated in one direction.)
