Fanuc Parameter 1860 ~upd~ Full -

Here is the interesting "hidden" feature regarding this parameter that many machinists overlook:

The value in Parameter 1860 is not static. It is automatically updated by the system in several critical moments: fanuc parameter 1860 full

In practice, for direct drive systems: $$ 1860 = \textReference Counter (1821) \div \textScrew Pitch (in pulses) $$ (Note: This varies heavily depending on whether the machine uses a Decimal Input method or the older Integer Input method.) Here is the interesting "hidden" feature regarding this

You cannot effectively manage Parameter 1860 without understanding , as they are the two halves of the absolute positioning system. Therefore, you would to the existing Parameter 1860

If you are experiencing vibration or servo alarms during rapid direction changes (like a G01 moving from X to Y), adjusting Parameter 1860 (along with 1620/1622) acts as a "dampener." It forces the axis to hesitate slightly during the transition, eliminating the shock to the ball screw.

Therefore, you would to the existing Parameter 1860.

Change back to 0 and press [RESET] to clear the resulting PWE alarm.
