Backlash compensation
Input range (mm):
+9.999 to -9.999
Default setting: 0.000
= no backlash compensation
During a change in direction, the mechanical play between the
encoder and table, the so-called backlash, can cause error.
Positive backlash: The rotary encoder moves before the table,
therefore the display value is too high (positive value input).
Negative backlash: The rotary encoder moves after the table,
therefore the display value is too low (negative value input).
