2. Start the blade and the machine will go through the procedure.
On V18APC: The head will move ahead for a trim cut, then retract, the shuttle vise will open and move slowly all
the way to the back. It will close, the front vise will open, and the shuttle vise will move slowly all the way to the front. The
front vise will clamp, the head will move forward for a cut and then retract.
On M16/20A: The head will move down for a trim cut then move back up. The shuttle vise will make the same move-
ments as above, and when it gets back to the front and the front vise clamps the head will move down for a cut then move
back up.
At this point the procedure is done and the line should read - LTH CLB “ENTER” OFF. The cycle light will still be flashing.
3. Move the cursor to ACT LTH line, type in the desired value (original parameter) and press ENTER.
4. To finish the procedure after completion, press the AUTO/MANUAL key and the value in 3) will then be accepted
by the PLC.
The above procedure may also be run with material: Load the machine with a good straight piece of material, long
enough for one full length of shuttle movement. Start the procedure as above (make sure you have proper band speed
and feed rate for material being cut). The machine will cycle exactly as above, trimming off the material and then shuttling
and cutting off one full shuttle stroke worth of material. The length must then be measured, as accurately as possible, the
kerf of the blade being used added to this measurement, and this value is then entered as the Actual Length parameter
(ACT LTH).
HEAD FEED RATE CALIBRATION
NOTE:
On “M” machines remove the head up limit switch target to prevent damage of the head up limit switch during calibration.
1. With the cursor on the line that reads - HD CLB “ENTER” OFF, press the ENTER key.
The line should then read - HD CLB “ENTER” ON, and the cycle start button should be flashing.
2. The head will move fully forward (down on M16/20A) and then will move fully backward (up on M16/20A). At this
point the procedure is done and the line should read - HD CLB “ENTER” OFF. The cycle light will still be flashing.
3. At any point after the procedure has started, move the cursor down to the ACT HD MVT line (ACT HT on
M16/20A), type in the desired value and press ENTER. To finish the procedure, press the AUTO/MANUAL key
and the value entered will then be accepted by the PLC.
This value is determined by measuring the full stroke movement of the head. Measurement on M16/20A is from the hori-
zontal wear plate to the tip of the blade teeth, along the face of the front vise datum jaw. For V18A the easiest measure-
ment is made along one of the head carriage linear bearing rails. A reference point is made on the rail where the edge of
the linear bearing is when the head has come fully forward. The measurement is then taken from this point to the same
bearing edge when the head has fully retracted.
ANGLE CALIBRATION
With no material in the machine, proceed as follows :
1. On V18APC: For left side angle calibration; with the cursor on the line that reads - L ANG CLB “ENTER” OFF,
press the ENTER key. (Right side calibration - R ANG CLB “ENTER” OFF). The line should then read - L ANG
CLB “ENTER” ON, and the cycle light should be flashing.
2. Start the blade. The head will swing to 90 degrees, if not already there, and then will come forward for a cut.
It will retract, swing to 45L, come forward for a cut, and then retract. At this point the left angle procedure is com-
plete. The line should then read - L ANG CLB “ENTER” OFF. The cycle light will still be flashing.
3. At any point after the procedure has started, or after it has finished, move the cursor down and type in the desired
value (original parameter or adjusted original) into the TTL L MEAS ANG line (into TTL R MEAS ANG for right
side), and press ENTER. To finish the procedure, press the AUTO/MANUAL key and the value entered will then
be accepted by the PLC.
For M16/20A or older V18APC
There is only one angle calibration line - ANG CLB “ENTER” OFF With the cursor on this line press ENTER key and line
will read - ANG CLB “ENTER” ON, and cycle light will be flashing. Start the blade and the procedure will execute;
