"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
• Continuation
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.

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.)
• The BUSY signal [X8 to XF] turns ON even when position control of movement
amount 0 is executed. However, since the ON time is short, the ON status may
not be detected in the sequence program.
