Background
Motion Detection establishes one or two “Motion Levels,” or speed ranges, with low
and high RPM values. These two ranges are independent of each other.
Using the MOTION ANDING screen, each output channel can be ANDed with either
Motion Level. ANDed outputs will be enabled only when the encoder speed is within the
specified speed range. Output channels that are not ANDed will be “on” whenever the
machine position is within their programmed setpoints, regardless of machine speed.
One use of Motion Levels and Motion ANDing is to turn off devices such as glue guns if
the machine stops or jams.
Screen
The Motion Detection screen displays the Motion Level, the Low RPM, and the High
RPM.
Programming
Use the numeric keys and ENT to change values for Motion Level, Low RPM, and High
RPM.
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 Level. This will turn the output
on constantly as long as the machine speed is within the specified Motion Level range.

Purpose
This screen allows the encoder position to be set to zero at the desired machine posi-
tion, eliminating the need to mechanically adjust the encoder shaft coupling to the ma-
chine.
Position Setup
In order to set the Position to match the machine position, simply stop the machine at a
known position and enter the desired Position value. For example, jog the machine to a
position at the start of a new cycle, then set the Position to “0.”
Absolute Offset
When you modify the Position, the Absolute Offset will change to the following number:
(Previous Absolute Offset) + (Change in Position)
• The Change in Position will be negative if the new position is less than the original
position, and will thus be subtracted from the Previous Absolute Offset.
Example: Absolute Offset is zero, and the machine is jogged to the start of a new cycle,
where the Position is 150. Using the keypad, the Position is reset to zero, for a change
in Position of (–150). The new Absolute Offset is thus zero minus 150. Since the model
of encoder used in this example shows positions from zero to 1000, the 150 is sub-
tracted from 1000, resulting in an Absolute Position of 850.
Absolute Offset is intended to be used for "archival purposes", in case you lose correct
machine position and need to set the machine back up. Absolute Offset can be modi-
fied using the numeric keypad.
