With the "major positioning control" ("high-level positioning control"), whether or not to continuously execute the
positioning data can be set with the "operation pattern". Outlines of the "operation patterns" are given below.
High-level
positioning
control
Block start (Normal start)
With one start, executes the positioning data in a random block
with the set order.
Page 462, Section 10.3.2
Condition start
Carries out condition judgment set in the "condition data" for the
designated positioning data, and then executes the "block start
data".
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.
Page 464, Section 10.3.3
Wait start
Carries out condition judgment set in the "condition data" for the
designated 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.)
Page 465, Section 10.3.4
Simultaneous start
Simultaneously executes the positioning data having the No. for
the axis designated with the "condition data". (Outputs pulses at
the same timing.)
Page 466, Section 10.3.5
Repeated start (FOR loop)
Repeats the program from the block start data set with the "FOR
loop" to the block start data set in "NEXT" for the designated No.
of times.
Page 467, Section 10.3.6
Repeated start (FOR condition)
Repeats the program from the block start data set with the "FOR
condition" to the block start data set in "NEXT" until the conditions
set in the "condition data" are established.
Page 468, Section 10.3.7
Multiple axes simultaneous start control
Starts the operation of multiple axes simultaneously according to
the pulse output level.
(Positioning start No. 9004, same as the "simultaneous start"
above)
Page 473, Section 10.5
Manual
control
JOG operation Outputs a pulse to drive unit while the JOG start signal is ON. Page 481, Section 11.2
Inching operation
Outputs pulses corresponding to minute movement amount by
manual operation to drive unit.
(Performs fine adjustment with the JOG start signal.)
Page 491, Section 11.3
Manual pulse generator operation
Outputs pulses commanded with the manual pulse generator to
drive unit. (Carry out fine adjustment, etc., at the pulse level.)

[Da.1] Operation pattern Details Reference
Independent positioning control
(Positioning complete)
When "independent positioning control" is set for the operation pattern of the started
positioning data, only the designated positioning data will be executed, and then the
positioning will end.
Page 342, Section 9.1.2 Continuous positioning control
When "continuous positioning control" is set for the operation pattern of the started positioning
data, after the designated positioning data is executed, the program will stop once, and then
the next following positioning data will be executed.
Continuous path control
When "continuous path control" is set for the operation pattern of the started positioning data,
the designated positioning data will be executed, and then without decelerating, the next
following positioning data will be executed.
