APPENDIX A
COMPUTER BATCH AND LENGTH CONTROLLER
A - 5
4. In the Length field, up to 999 feet and 11.999 inches.
5. The controller displays the message “Pause After Job xx?” (Where xx is the job
number assigned in step 1). Select:
- Yes to have the machine halt automatically after the selected job number is
finished.
- No to have the machine change lengths “on-the-fly” and run the job following the
selected job without first stopping.

Note: To restart the machine after an automatic halt, press [Run] .

Note: To increase productivity, additional jobs can be programmed while the
machine is running previously programmed jobs.
Automatic Operation
The MP465 runs all programmed jobs automatically.
•
To start the machine after all desired jobs have been programmed, press [Run] .
•
To stop the machine at any time, press [Halt ] .
The machine halts automatically when all programmed jobs are completed.

Note: If the encoder is counting in the negative direction, change the encoder
direction in the Setup Screen as described previously.
Length Calibration

Note: Calibration is typically required only during machine commissioning or after
changing coil stock.
Length calibration adjusts for errors in the size and tracking of the measuring wheel and
is expressed as a percentage, with 100% being no correction. Increasing the correction
factor causes the parts to become longer and decreasing the value shrinks the parts.
The MP465 controller’s length calibration feature automatically computes a new
correction factor by comparing the desired (Programmed) length to the actual (Measured)
length. Length Calibration should be used any time part lengths are incorrect in a
consistent manner (e.g., all parts 1mm too long, etc.). Length calibration will not fix a
situation where parts are inconsistent (e.g., parts vary +10 to -10mm).

Note: When calculating the correction factor, make several parts and use the average
of these parts for the part length. The first part produced should not be used in this
calculation since it may be inaccurate due to shear reaction or other variances.
To calibrate the MP465 controller,
6. The controller can be calibrated anytime the measured part length is not matching
programmed part length.
