9MAJOR POSITIONING CONTROL

[2]1-axis linear control (INC linear 1)

Operation chart

MELSEC-Q

In incremental 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 a position at the end of the movement amount set in "

Da.6

Positioning address/movement amount". The movement direction is determined by the sign of the movement amount.

	Start point address
	(current stop position)
Reverese direction	Forward direction
Movement direction for	Movement direction for
a negative movement amount	a positive movement amount

Example

When the start point address is 5000, and the movement amount is -7000, positioning is carried out to the -2000 position.

Address after positioning control	Start point address
	(current stop position)

-3000 -2000 -1000 0 1000 2000 3000 4000 5000 6000

Positioning control in the reverse direction (movement amount -7000)

Axis 1 Positioning data No. 1

Positioning data setting example

The following table shows setting examples when "1-axis linear control (INC 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.
	Control system	INC linear 1	Set incremental system 1-axis linear control.
Da.3	Acceleration time	1	Designate the value set in "	Pr.25	Acceleration time 1" as the
	No.		acceleration time at start.
Da.4	Deceleration time	0	Designate the value set in "	Pr.10	Deceleration time 0" as the
	No.		deceleration time at deceleration.
Da.5	Axis to be	–	Setting not required (setting value will be ignored).
	interpolated
			Set the movement amount. (Assuming "mm" is set in "				Unit
Da.6	Positioning address/	-7000.0∝m				Pr.1
	movement amount		setting".)
	Arc address	–	Setting not required (setting value will be ignored).
	Command speed	6000.00mm/min	Set the speed during movement.
Da.9	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.
