Linear Error
Correction (LEC)
Scroll through the Setup menu to highlight Linear Error Correc-
tion (LEC). Linear error correction coefficients are used to com-
pensate for overall encoder and machine travel variations. A stan-
dard is measured, and the measured value is compared to the
known value of the standard to generate the correction coeffi-
cient. Correction coefficients are generated for each axis and
used in subsequent measurements to provide linear compensa-
tion for encoder variations.
Press the right arrow key to select items in the right portion of
the screen.
Enter the nominal value of the standard for each axis into the
appropriate Standard data field using the numeric keypad on the
front panel. Use the down cursor arrow to scroll to the desired
data field.
