Fanuc Parameter 1860 !exclusive! 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.)

DS0300 Alarm (APZ = 0).

You cannot effectively manage Parameter 1860 without understanding , as they are the two halves of the absolute positioning system. fanuc parameter 1860 full

Most machines will not run a 10 ms 1860 due to mechanical resonance. Multiply by 3–5x for safety (e.g., 40–60 ms).

Sudden jumps or inconsistent "wrap-around" behavior in this parameter can signal a failing encoder or noise in the communication line between the motor and the CNC control . Safety and Modification In practice, for direct drive systems: $$ 1860

Regularly review Parameter 1860 as part of your preventive maintenance schedule. After six months of heavy use, ballscrew wear can change the system's inertia, and a once-perfect 1860 value may need a 10-20% increase to maintain smooth motion.

Locate the parameter and change it from 0 to 1 . Ignore the standard PWE warning alarm. Phase 2: Cycle the APZ Bit Press the SYSTEM hard key, then select the PARAM soft key. Search for Parameter 1815 . Find the axis you need to adjust and look at Bit 4 (APZ) . Set APZ to 0 . Multiply by 3–5x for safety (e

Move the machine axis manually (using the handwheel/jog) to its true, physical home location or alignment marks. Go back to Parameter 1815 and change to 1 . Phase 3: Finalize and Verify Power cycle the CNC machine.
