Backlash Compensation - HEIDENHAIN ND 522 - 2-2011 User Manual

Backlash Compensation

When using a rotary encoder with a lead screw, a change in direction
of the table might cause an error in the displayed position due to
clearances within the lead screw assembly. This clearance is referred
to as backlash. This error can be compensated for by inputting the
amount of backlash within the lead screw into the Backlash
Compensation feature.
If the rotary encoder is ahead of the table (displayed value is greater
than the table's true position), this is called positive backlash, and the
value entered should be the positive value of the amount of error.
No Backlash Compensation is 0.000.
