10.6.1 Starting high-level positioning control

To execute high-level positioning control, a sequence program must be created to start

the control in the same method as for major positioning control.

The following shows the procedure for starting the "1st point block start data"

(regarded as block No. 7000) set in axis 1.

Control by designated
positioning data

When carrying out a positioning start with the
next scan after a positioning operation is
completed, input signal X10 as an interlock so
that the start is carried out once the X10 signal
turns OFF after the Y10 signal turns OFF.

1) Set "7000" in " Cd. 3 Positioning start No.".

(This establishes that the control as "high-level positioning control" using block start data.)

2) Set the point No. of the "block start data" to be started. (In this case "1".)

3) Turn ON the start signal.

4) The positioning data set in the "1st point block start data" is started.
