10HIGH-LEVEL POSITIONING CONTROL

10.1 Outline of high-level positioning control

MELSEC-Q

In "high-level positioning control" the execution order and execution conditions of the "positioning data" are set to carry out more applied positioning. (The execution order and execution conditions are set in the "block start data" and "condition data".)

The following applied positioning controls can be carried out with "high-level positioning control".

High-level positioning	Details
control
Block 1 start	With one start, executes the positioning data in a random block with the set order.
(Normal start)
	Carries out condition judgment set in the "condition data" for the designated
	positioning data, and then executes the "block start data".
Condition start	• When the condition is established, the " block start data" is executed.

•When not established, that " block start data" is ignored, and the next point's " block start data" is executed.

	Carries out condition judgment set in the "condition data" for the designated
Wait start	positioning data, and then executes the " block start data".
	• When the condition is established, the " block start data" is executed.
	• When not established, stops the control until the condition is established. (Waits.)
Simultaneous start	Simultaneously executes the positioning data having the No. for the axis designated
2	with the "condition data". (Outputs pulses at the same timing.)
Repeated start (FOR	Repeats the program from the " block start data" set with the "FOR loop" to the "
loop)	block start data" set in "NEXT" for the designated No. of times.
Repeated start (FOR	Repeats the program from the " block start data" set with the "FOR condition" to the "
condition)	block start data" set in "NEXT" until the conditions set in the "condition data" are
	established.

High-level positioning control sub functions

"High-level positioning control" uses the "positioning data" set with the "major positioning control". Refer to Section 3.2.4 "Combination of QD75 main functions and sub functions" for details on sub functions that can be combined with the major positioning control.

Note that the sub function Section 12.7.8 "Pre-reading start function" cannot be used together with "high-level positioning control".

High-level positioning control from peripheral devices

"High-level positioning control" (start of the "block start data") can be executed from GX Configurator-QP test mode.

Refer to GX Configurator-QP Operating Manual for details on starting of the "block start data" from GX Configurator-QP.

REMARK

Block 1:

"1 block" is defined as all the data continuing from the positioning data in which "continuous positioning control" or "continuous path control" is set in the

operation pattern (

Da.1

) to the positioning data in which "independent

positioning control (Positioning complete)" is set.

Simultaneous start 2:

Besides the simultaneous start of "block start data" system, the "simultaneous starts" include the "multiple axes simultaneous start control" of control system. Refer to Section 10.5 "Multiple axes simultaneous start control" for details.
