Backlash Compensation. HEIDENHAIN ND 522 - 2-2011, ND 523

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.
