INCON-M84/M86/M86R Manual

3.2.3 Backlash (Unit: μm)

When the movement of the axis change direction, INCON-M84/M86/M86R will add backlash as compensation. Within the machine movement system there need to be tiny gap, so the movements is possible.

This tiny gap will cause differentiation within reverse direction. When conducting negative movement, compensating this tiny differentiation, is call backlash compensation, to ensure the CNC controller can provide the accurate compensation, backlash value, should be added into the parameter after calculation and after opening the machine, you must execute manual homing, to ensure the accurate backlash compensation.
