Block start (Normal start)

With one start, executes the positioning data in a random block

10.3.2

 

with the set order.

 

 

 

 

 

Carries out condition judgment set in the "condition data" for

 

 

 

the designated positioning data, and then executes the "block

 

 

Condition start

start data".

10.3.3

 

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.

 

 

 

 

 

control

 

Carries out condition judgment set in the "condition data" for

 

 

the designated positioning data, and then executes the "block

 

 

 

 

 

Wait start

start data".

10.3.4

positioning

When the condition is established, the "block start data" is

 

 

 

executed. When not established, stops the control until the

 

 

 

 

 

 

condition is established. (Waits.)

 

 

 

 

 

level-High

 

Simultaneously executes the positioning data having the No.

 

Simultaneous start

for the axis designated with the "condition data". (Outputs

10.3.5

 

 

 

pulses at the same timing.)

 

 

 

Repeats the program from the block start data set with the

 

 

Repeated start (FOR loop)

"FOR loop" to the block start data set in "NEXT" for the

10.3.6

 

 

designated No. of times.

 

 

 

Repeats the program from the block start data set with the

 

 

Repeated start (FOR condition)

"FOR condition" to the block start data set in "NEXT" until the

10.3.7

 

 

conditions set in the "condition data" are established.

 

 

 

 

 

 

 

Starts the operation of multiple axes simultaneously according

 

 

Multiple axes simultaneous start

to the pulse output level.

control

(Positioning start No. 9004, same as the "simultaneous start"

 

 

 

 

above)

 

control

JOG operation

Outputs a pulse to drive unit while the JOG start signal is ON.

11.2

 

 

 

Inching operation

manual operation to drive unit.

11.3

Manual

 

Outputs pulses corresponding to minute movement amount by

 

 

(Performs fine adjustment with the JOG start signal.)

 

 

 

 

 

Manual pulse generator operation

Outputs pulses commanded with the manual pulse generator to

11.4

 

drive unit. (Carry out fine adjustment, etc., at the pulse level.)

 

 

 

 

 

 

 

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.

When "independent positioning control" is set for the operation

 

Independent positioning control

pattern of the started positioning data, only the designated

 

(Positioning complete)

positioning data will be executed, and then the positioning will

 

 

 

 

end.

 

 

 

 

When "continuous positioning control" is set for the operation

 

Continuous positioning control

pattern of the started positioning data, after the designated

9.1.2

positioning data is executed, the program will stop once, and

 

 

 

 

 

 

 

then the next following positioning data will be executed.

 

 

 

 

 

 

 

 

 

When "continuous path control" is set for the operation pattern

 

Continuous path control

of the started positioning data, the designated positioning data

 

will be executed, and then without decelerating, the next

 

 

 

 

 

 

 

 

following positioning data will be executed.
