9 MAJOR POSITIONING CONTROL
[2] Continuous positioning control
(1) The machine always automatically decelerates each time the positioning is
completed. Acceleration is then carried out after the QD75 command speed
reaches 0 to carry out the next positioning data operation. If a dwell time is
designated, the acceleration is carried out after the designated time elapses.
(2) In operation by continuous positioning control (operation pattern "01"), the
next positioning No. is automatically executed. Always set operation pattern
"00" in the last positioning data to complete the positioning.
If the operation pattern is set to positioning continue ("01" or "11"), the
operation will continue until operation pattern "00" is found.
If the operation pattern "00" cannot be found, the operation may be carried
out until the positioning data No. 600. If the operation pattern of the
positioning data No. 600 is not completed, the operation will be started again
from the positioning data No. 1.
