Linear Error Compensation
With MICRO-LINE , you can compensate for machine tool wear. If you
know the linear error compensation (LEC) value in parts-per-million
(PPM), you can enter it directly.
If you don’t know the LEC, use the formula on the next page to determine
the value for each axis.
• Move to the “Linear Error Compensation” display in the Setup
mode. (Press SETUP and then the ENTER key until “LEC”
appears).
• Press the X or Z key for the axis you want to change.
MICRO-LINE will display the current LEC value for that axis.
• Using the keypad, enter the linear error compensation factor
(in PPM), followed by the ± key for negative values. The number
must be within -9999 and 9999 (use whole numbers). The formula for
calculating the value is on the next page.
• After you complete setting your LEC, press ENTER to
continue with setup or press ENTER then SETUP to return to the
normal DRO display.
