Description Motion Detection establishes one or two “Motion Detection Levels,” or speed ranges,
with low and high RPM values. These two ranges are independent of each other.
Each output channel can be ANDed with either Motion Level. ANDed outputs will be
enabled only when the resolver speed is within the specified speed range. Output chan-
nels that are not ANDed will be “on” whenever the machine position is within their
programmed setpoints, regardless of machine speed. One use of Motion Detection
Levels and Motion ANDing is to turn off devices such as glue guns if the machine stops
or jams.
The MOTION DETECTION function is used to establish one or two Motion Detection
Levels. Once the Motion Detection Levels are programmed, use MOTION ANDING to
tie individual output channels to the Motion Detection Levels.
Motion Detector
An output channel can be used as a motion detector by programming it to be on at “1”
and off at “1,” and then ANDing it with the desired Motion Detection Level. This will turn
the output on constantly as long as the machine speed is within the specified Motion
Detection Level range.
