Chapter 6 Sequence Program Used for

Positioning Control

6

The programs required to carry out positioning control with the QD75 are explained in this chapter.

The sequence program required for control is created allowing for the "start conditions", "start time chart", "device settings" and general control configuration. (The parameters, positioning data, block start data and condition data, etc., must be set in the QD75 according to the control to be executed, and program for setting the control data or a program for starting the various control must be created.)

The first half of this chapter explains the program configuration of general control, and the latter half explains the program details. Create the required program while referring to the various control details explained in Section 2, and to Chapter 5 "Data used for positioning control".
