9.2.2 1-axis linear control

MELSEC-Q

In "1-axis linear control" ("

Da.2

Control system" = ABS linear 1, INC linear 1), one

motor is used to carry out position control in a set axis direction.

[1] 1-axis linear control (ABS linear 1)

Operation chart

In absolute system 1-axis linear control, addresses established by a machine OPR are used. Positioning is carried out from the current stop position (start point

address) to the address (end point address) set in " address/movement amount".

Example

Da.6

Positioning

When the start point address (current stop position) is 1000, and the end point address (positioning address) is 8000, positioning is carried out in the positive direction for a movement amount of 7000 (8000-1000)

	Start point address	End point address
	(current stop position)	(positioning address)
0	1000	8000

Positioning control (movement amount 7000)

Axis 1 Positioning data No. 1

Positioning data setting example

The following table shows setting examples when "1-axis linear control (ABS linear 1)" is set in positioning data No. 1 of axis 1.

Setting item		Setting example		Setting details
Da.1	Operation pattern	Positioning	Set "Positioning complete" assuming the next positioning data will not
		complete	be executed.
Da.2	Control system	ABS linear 1	Set absolute system 1-axis linear control.
Da.3	Acceleration time	1	Designate the value set in "		Acceleration time 1" as the
				Pr.25
	No.		acceleration time at start.
Da.4	Deceleration time	0	Designate the value set in "		Deceleration time 0" as the
				Pr.10
	No.		deceleration time at deceleration.
Da.5	Axis to be	–	Setting not required (setting value will be ignored).
	interpolated
			Set the positioning address. (Assuming "mm" is set in "				Unit
	Positioning address/	8000.0∝ m				Pr.1
	movement amount		setting".)
Da.7	Arc address	–	Setting not required (setting value will be ignored).
Da.8	Command speed	6000.00mm/min	Set the speed during movement to the positioning address.
	Dwell time	500ms	Set the time the machine dwells after the positioning stop (pulse output
			stop) to the output of the positioning complete signal.
Da.10	M code	10	Set this when other sub operation commands are issued in combination
			with the No. 1 positioning data.

Refer to Section 5.3 "List of positioning data" for information on the setting details.
