ADVANCED POSITIONING CONTROL
10.1 Outline of advanced positioning control
In "advanced 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 "start block data" and "condition data".)
The following applied positioning controls can be carried out with "advanced
positioning control".
Advanced
positioning control
Block* start
With one start, executes the positioning data in a random block with the set
(Normal start)
order.
Carries out condition judgment set in the "condition data" for the
designated positioning data, and then executes the "start block data".
Condition start
When the condition is established, the "start block data" is executed. When
not established, that "start block data" is ignored, and the next point's "start
block data" is executed.
Carries out condition judgment set in the "condition data" for the
designated positioning data, and then executes the "start block data".
Wait start
When the condition is established, the "start block data" is executed. When
not established, stops the control until the condition is established. (Waits.)
Simultaneously executes the positioning data having the No. for the axis
Simultaneous start
designated with the "condition data". (Outputs pulses at the same timing.)
Stop
Stops the positioning operation.
Repeated start
Repeats the program from the "start block data" set with the "FOR loop" to
(FOR loop)
the "start block data" set in "NEXT" for the designated No. of times.
Repeats the program from the "start block data" set with the "FOR
Repeated start
condition" to the "start block data" set in "NEXT" until the conditions set in
(FOR condition)
the "condition data" are established.
Advanced positioning control auxiliary functions
"Advanced positioning control" uses the "positioning data" set with the "main
positioning control". Refer to "3.3.4 Combination of D75P2 main functions and
auxiliary functions" for details on auxiliary functions that can be combined with the
main positioning control.
Advanced positioning control from peripheral devices
"Advanced positioning control" (start of the "start block data") can be executed
from the AD75 software package test mode.
Refer to the AD75 Software Package Operating Manual for details on starting of
the "start block data" from the AD75 software package.
REMARK
Block *:
"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.
