9 POSITIONING CONTROL
9.1.2 Operation patterns of positioning controls
"Positioning control" starts with positioning data No. 1 and allows you to set in " Da. 1
Operation pattern" whether the subsequent consecutive data will be executed
continuously or not. There are the following three different "operation patterns" [1] to
[3].
•
Termination [1] Positioning termination (operation pattern: 0)
•
Continuation [2] Continuous positioning control (operation pattern: 1)
[3] Continuous path control (operation pattern: 2)
The following shows examples of operation patterns when "1-axis linear control (ABS)"
is set in positioning data No. 1 to No. 6 of axis 1. Details of each operation pattern are
shown on the following pages.

(One motor is driven, and positioning control is carried out to an addresses designated in one direction.)

POINT
The positioning data of the QD70 is started from positioning data No. 1 by setting
"0" in " Cd. 3 Start method".
(It cannot be started from any positioning data of No. 2 to No. 10.)
