9 MAIN POSITIONING CONTROL
(2) Continuous positioning control
(a) The machine always automatically decelerates each time the positioning is
completed. Acceleration is then carried out after the AD75 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.
(b) 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 terminate the positioning.
If the operation pattern is set to positioning continue ("01" or "11"), the
operation will continue until operation pattern "00" is found.
The operation may be carried out until the max. data item No. 600 if
operation pattern "00" cannot be found because it was not set in the last
positioning data.
