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.
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.
