Note 1. When the error compensation value is entered into the table, the entered
value is rounded to an integer multiple of encoder resolution. For example, if
the encoder resolution is 2 um and the entered compensation value is 1 um,
the program will forcibly convert it to 2 um. If the input is 0.5 um, it will be
converted to 0 um.
Note 2. Because the displayed accuracy is only to the third decimal, select the
appropriate unit for “Position” and “Error”.
Step 3. Check the option of “Error map enable” ( ).
