Fanuc Parameter 1860 Fixed Direct

Keep a log of original 1860, date of change, and observed behavior. Copy parameters to a memory card before tuning.

Follow the absolute encoder resynchronization procedure described above, which will automatically regenerate correct 1860 and 1861 values.

Key in the required value dictated by your machine tool builder's documentation. Press the key. Turn the PWE setting back to 0 .

Parameter 1860 is a bit-type or integer-type parameter (depending on the specific FANUC control series, such as 0i-D/F, 16i/18i/21i, or 30i/31i/32i) that dictates the for each individual axis. fanuc parameter 1860

1. Navigate to the parameter lock. Change it from a zero to a one. 3. Press the SYSTEM hard key and navigate to parameter 1815 en.industryarena.com

Always take a full SRAM or ALLPARAM backup to a PCMCIA card or USB drive before changing any parameter in the 1000–2000 range.

Parameter 1815.6 (NRT) = 0 ──> Reference position updates when passing PRM 1860 value Parameter 1815.6 (NRT) = 1 ──> Reference position updating is not performed Purpose of Coordinate Rounding Keep a log of original 1860, date of

In FANUC CNC systems (such as the Series 0i, 16i, 18i, and 31i), Parameter 1860 functions alongside related axis control parameters to establish how the control unit updates its reference position loop. Interaction with Parameter 1815

: This is typically a "read-only" parameter for general operation; the CNC system updates it automatically as the axis moves.

: Controls backlash compensation for the axes. How to Modify (If Required) Key in the required value dictated by your

Alternative: Use the soft key to add or subtract a specific increment to the existing value. Step 5: Cycle Power and Clear Alarms

The system will prompt you to turn the CNC machine off and back on. Step 3: Align the Axis Mechanically

Fanuc stores the current position data of the absolute pulse coder (APC) for each axis.

To access and adjust parameter 1860, you will need to navigate to the parameter menu on your Fanuc control system. The exact steps may vary depending on the specific control system model and version you are using. Typically, you will need to:
