Fanuc Parameter 1860 !new!

Machine tools inevitably develop backlash over time due to mechanical wear in ball screws, nuts, and other transmission components. The two-stage backlash acceleration function helps compensate for this mechanical play by applying an additional acceleration pulse when reversing axis direction.

Power up the CNC system.

Even with absolute encoders (Parameter 1815#5 = 1), the initial reference position establishment (APZ setting) uses Parameter 1860. After APZ is set, absolute encoders do not use 1860 during power-on, but any manual reference return (holding P and CAN on boot) will. fanuc parameter 1860
