Fanuc Parameter 1860 [patched] -
The machine will display a flashing "P/S 100 PARAMETER WRITE ENABLE" alarm. This is normal and expected. Step 2: Navigate to Parameter 1860 Press the hard key. Press the PARAM softkey. Type 1860 and press the No. SRCH (Number Search) softkey.
Go back to the screen and change PARAMETER WRITE (PWE) back to 0 . Press the RESET key to clear the PWE alarm.

Disclaimer: Modifying FANUC parameters can drastically alter machine behavior. Always back up your parameters before making changes, and clear the workspace of tools and fixtures before testing. Step 1: Enable Parameter Writing (PWE) Press the mode button on your operator panel. Press the OFFSET/SETTING hard key. Press the SETTING softkey. fanuc parameter 1860
Parameter 1860 plays a crucial role in the Two-Stage Backlash Acceleration function in various FANUC control models. According to documentation for FANUC 0i-MC controls, parameter 1860 represents the . In the Series 15i/150i Model B Maintenance Manual, this parameter is explicitly identified as the "1ST ACC VALUE" for two-stage backlash acceleration. This function provides enhanced control over axis reversal behavior, improving machining accuracy by compensating for mechanical backlash in a more sophisticated manner than standard single-stage compensation.
Set APC (Parameter 1815#5) = 1.
According to official FANUC Parameter Manuals , parameter 1860 is . Industry field technicians on platforms like the Practical Machinist Forums note that manually keying a value into parameter 1860 triggers a required machine powercycle, after which the control system frequently overrides or misinterprets the input, leading to unexpected axis shifts or positioning errors.

| Parameter | Function | |---|---| | | Dual position feedback maximum amplitude in some models; paired with parameter 1860 for reference point preservation in rotary axes | | 1815#4 (APZ) | Indicates whether correspondence between machine position and absolute position detector is established; set to 0 when parameter 1860/1861 are modified | | 1815#5 (APC) | Enables/disables absolute position detector function; cleared when re-establishing reference points | | 1851 | Standard backlash compensation amount for cutting feed (most common backlash parameter) | | 1852 | Fast (rapid traverse) backlash compensation amount | | 1260 | Defines the shift value per rotation (rounding value) used when determining whether to renew reference point data |
To understand Parameter 1860, it helps to look at , which manages the absolute position detector setup. Parameter 1815 includes crucial bits such as:
