Axis backlash adjustment and backlash compensation ...

Backlash can be tested with indicators, lasers, ballbars or other measuring devices to determine how much motion is lost when an axis reverses direction. This value is entered in the machines parameters, so when an axis changes direction, it compensates the amount in the parameter to determine when the axis will physically move.

WHAT IS BACKLASH AND HOW TO CORRECT IT - MachMotion

Software backlash compensation works by entering the given or measured backlash of the machine into the control system. The control knows when to add in this additional movement by the direction it is commanding the machine to move. The software simply subtracts out the backlash depending on which side of the threads are currently making contact.
