FANUC Parameter 1860 is a powerful testament to the flexibility and depth of FANUC's CNC controls. Whether it is silently maintaining the absolute position of your machine's axes or actively suppressing backlash to deliver a flawless surface finish, this single parameter plays a pivotal role in the machine's core functionality. By understanding its dual nature, respecting the warning signs, and following the proper configuration procedures, you can unlock the full potential of your FANUC-controlled machine tool, ensuring it produces accurate, high-quality parts reliably for years to come.
Always change PWE back to 0 after you finish making your parameter changes to prevent accidental corruption.
Keep a detailed log of every parameter change you make, noting the original value, the new value, the date, and the reason for the change. This documentation is invaluable for troubleshooting and for rolling back changes if a new setting causes unintended consequences. fanuc parameter 1860 work

Parameter 1860 is most often used during maintenance or after a mechanical crash to reset the home position. A typical procedure involves: Moving the axis to the desired physical home position. Setting the APZ bit (Parameter 1860) to for that axis. Powering the machine off and back on. FANUC Parameter 1860 is a powerful testament to
If you change Parameter 2022 because a machine axis is physically moving left instead of right, you also change Parameter 1860.
: You must physically drive the axis to a known position (usually a witness mark or home position). Always change PWE back to 0 after you
Fanuc controls often split override limits into two parameters based on the cutting mode:

If the control rejects the change, jog the axis slightly in the positive direction and try again. Power cycle the machine one final time. Vital Safety Precautions
