CP-27 BATCH LIMIT
The Batch Counter is an up-counter that is cleared to zero by the Batch Reset input. Use the
Batch Done Output to shut off the system when the Batch Count has been reached. You can
count either the number of Follower traverses or the number of Lead reel revolutions. If you
count Follower traverses, each direction counts as one traverse. If you count Lead revolutions,
each wrap of the reel (or layer), is one lead revolution. Enter the total number that you want
counted in Batch Limit (CP-27).
CP-28 BATCH PREACT DISTANCE
The Batch PreAct Distance (CP-28) parameter is used only if the Batch Format (CP-26) has
been set to number “1” (Follower traverses). CP-28 allows you to set a specific distance at
which to activate the Batch Done. This can be at the end dwell or any distance from dwell, up to
the Accel/Decel Length at the opposite end from dwell. If you enter a number that would go
beyond the Accel/Decel Length, the M-Traverse will automatically default to the Accel/Decel
Length. For example, your reel is 10 inches long, with an Accel /Decel Length of 1 inch on each
end, and the laypitch profile is 8 inches. CP-28 will default at 9 inches for any amount above 9
inches that you enter in CP-28, because the opposite Accel /Decel is 9 inches from the dwell.
See the diagram below for a profile representation of this example:

9"
CP-29 UNIPOLAR/BIPOLAR
The M-Traverse can interface with either single quadrant (direction) drives or with bi-directional
drives that use bipolar voltage commands (positive and negative) to indicate the direction. Enter
“1” for Unipolar operation or “2” for Bipolar operation.
NOTE: CP-29 can not be changed during “Run”.
CP-30 AT-HOME BAND
The At-Home Band (CP-30) parameter allows for a certain amount of “range” in the Home
position, measured in encoder lines. Although the Home Set and Home Seek inputs place home
exactly at “0”, the At-Home Band parameter allows home to be located in a band that is
measured in negative and positive encoder lines on each side of the "0" mark. Enter the desired
number of encoder lines in CP-30.
NOTE: The Follower mechanism must be positioned within the At-Home Band before “Run” is
entered. The Follower position must also be within the At-Home band to activate the
At-Home LED indicator (front panel) and the At-Home discrete output.
