5.2.1 QD74MH control functions

(1) OPR control
"OPR control" is a function that established the start point for carrying out
positioning control, and carries out positioning toward that start point. This is
used to return a workpiece, located at a position other than the OP when the
power is turned ON or after positioning stop, to the OP. The OPR control is
preregistered in the QD74MH as the "Positioning start data No. 9000 (OPR)".
(Refer to Chapter 7 "OPR Control".)
(2) Major positioning control
This control is carried out using the positioning data stored in the QD74MH.
Positioning control is executed by setting the required items in this positioning
data and starting that positioning data. An operation pattern can be set in this
positioning data, and with this whether to carry out control with continuous
positioning data (ex.: positioning data No.1, No.2, No.3, ...) can be set.
(Refer to Chapter 8 "Positioning Control".)
(3) Manual control
Use this manual control to move the workpiece to a random position (JOG
operation) and to finely adjust the positioning (incremental feed operation).
(Refer to Chapter 9 "Manual Control".)
