9   MAJOR POSITIONING CONTROL 
 
POINT 
 
The BUSY signal [XC, XD, XE, 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 PLC program. 
 
 
[1]   Independent positioning control (Positioning complete) 
This control is set when executing only one designated data item of positioning. If 
a dwell time is designated, the positioning will complete after the designated time 
elapses.  
This data (operation pattern [00] data) becomes the end of block data when 
carrying out block positioning. (The positioning stops after this data is executed.)
