Fanuc Parameter 1860 Work //top\\ Jun 2026

You typically only touch this parameter during:

Parameter 1860 is configured as an . This means that X, Y, Z, and any auxiliary rotary axes (like a B-axis or C-axis table) will each have an independent entry line under the 1860 field.

: Technicians determine the difference between the desired physical home position and the current absolute position reading. This difference is converted into "detection units" (pulses) and entered into 1860. Synchronization fanuc parameter 1860 work

What are you currently using (e.g., 0i-D, 0i-F, 31i)?

The control treats the axis as if it uses an incremental encoder. You typically only touch this parameter during: Parameter

Press the function key and access the [PARAM] sub-screen. Search for Parameter 1815 . Identify the target axis (e.g., X, Y, or Z). Change the APZ bit (typically Bit 4) from 1 to 0 .

Understanding and correctly applying Parameter 1860 can save significant time and frustration. Here are some key points: This difference is converted into "detection units" (pulses)

Before calculating the shift, you must know what 1 unit in Parameter 1860 represents. Check your machine manual or parameters (like Parameter 1820) to find the command multiplier. On most metric machines, .

Carefully move the chosen axis to its physical zero position.

If you suspect your 1860 setting is off, follow the calibration steps in this guide. Your machine—and your tool budget—will thank you.

If you replace a motor, you should first clear and reset the home position using to get the machine roughly into place. Afterward, run a test piece or check a reference gauge, and use Parameter 1860 to dial in the final accuracy down to the micron. Important Safety Tips When Working with Grid Shifts
