30 Setting the Backlash Compensation

30.1 Backlash Compensation

Travel amount of a machine table may become less than the commanded amount due to the error (backlash) caused by

reversal of the direction of the axis.

The backlash compensation is a function which automatically adds compensation amount to the travel amount when the

direction of the axis is reversed.

Machine table

There are two types of backlash compensation as follows.

 G0 backlash (#2011 G0back)

Compensation amount that is used when an axis moved at the rapid traverse speed (G0).

Compensation amount is also measured at rapid traverse speed.

 G1 backlash (#2012 G1back)

Compensation amount that is used when an axis moved at cutting feedrate (G1, G2, G3).

Compensation amount to be set is measured using the most commonly used feedrate.
