9 MAJOR POSITIONING CONTROL

9.1.2 Operation patterns of major positioning controls

MELSEC-Q

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.

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.

< Operation example when "1-axis linear positioning" is set in the positioning data of axis 1 >

(Setting details)

			No.1 Start
Positioning data No.1 Positioning to address [A] at command speed [a]
		Operation pattern = 11: Continuous path control
No.2		Operation pattern = 11: Continuous path control
	Positioning to address [B] at command speed [b]
No.3		Operation pattern = 01: Continuous positioning control
	Positioning to address [C] at command speed [a]
No.4		Operation pattern = 01: Continuous positioning control
	Positioning to address [D] at command speed [b]
No.5		Operation pattern = 00: Independent positioning control
	Positioning to address [E] at command speed [a]
		(Positioning complete)
No.6			Control stop
	Positioning to address [F] at command speed [a]
		Operation pattern = 11: Continuous path control

The machine stops, and then continues the next positioning.

Positioning is terminated

For 1-axis linear control

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

POINT

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 sequence program.
