Operation Patterns Of Major Positioning Controls - Mitsubishi Electric MELSEC-L LD75P User Manual

Operation patterns of major positioning controls

In "major positioning control" (high-level positioning control), "[Da.1] Operation pattern" can be set to designate
whether to continue executing positioning data after the started positioning data. The "operation pattern" includes the
following 3 types ((1) to (3)).
The following shows examples of operation patterns when "1-axis linear control (ABS linear 1)" is set in positioning
data No. 1 to No. 6 of axis 1.

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