CALIBRATION PROCEDURE
For Mitsubishi PLC100 with 2100 Series software
Length calibration may be achieved in two ways: by inputting the ACTUAL LENGTH or LENGTH CONSTANT parameter.
1. To determine ACTUAL LENGTH value, use MANUAL MODE to position a piece of material, which is approx. 5”
longer that the shuttle full stroke length (i.e. S20A = 34.00”) and close the front vise. Start the blade and make
a trim cut. Raise the head and fully retract the shuttle. Clamp the material and move the shuttle fully forward.
Make a cut and measure the part length.
In SERVICE MODE, move the cursor to the ACTUAL LENGTH parameter and enter the length of the cut part plus
the actual kerf value. Then exit the parameters by pressing the RETURN key.
NOTE: When entering the ACTUAL LENGTH, always round down.
2. To determine LENGTH CONSTANT value, use this formula:
LENGTH CONSTANT = ENCODER PINION CIRCUMFERENCE (TTd)
y
ENCODER RESOLUTION
Example:
For a 1” pinion diameter and 2500 PPR encoder:
LTH CONST = TTd
y
2500 PPR = 0.0012567
TO CHECK LENGTH CONTROL CONSISTENCY:
a. Perform test cuts of three different lengths (i.e. 1”, 12”, 20”) and measure as accurately as possible with a Vernier
or dial caliper
b. If the measurements indicate a linear problem (measured length error increases as the programmed length in-
creases), the ACTUAL LENGTH or LENGTH CONSTANT value will have to be adjusted.
x
If part length error gets longer as the programmed length increases, ACTUAL LENGTH value should be de-
creased
x
If part length error gets shorter as the programmed length increases, ACTUAL LENGTH value should be in-
creased
x
Make small adjustments at a time (i.e. .020” - .030”) and recheck with test cuts
