At its core, Parameter 1860 functions as a for a given axis. In many Fanuc systems, this parameter displays a raw value representing the absolute position of the axis as reported by the encoder .
Cut a circle (e.g., 100mm diameter) at a moderate feed rate (e.g., 1000mm/min) to check for quadrant protrusions.
The screen will display Parameter 1860 with separate columns for each axis (X, Y, Z, etc.). Step 3: Edit and Input the Value fanuc parameter 1860 full
If a motor is uncoupled, a ballscrew slips, or a catastrophic crash occurs, the mechanical zero position changes dramatically. The value historically saved in 1860 becomes structurally invalid, throwing position deviation limits or soft overtravel errors. Step-by-Step Guide: Resetting the Reference System
-axis home position is reset, the value in 1860 changes, which may require you to re-verify the tool change height stored in Parameter 1241 en.industryarena.com How to View/Set Enable Writing : In MDI mode, go to the screen and set PARAMETER WRITE = 1 : Press the hard key, then the to locate the parameter for each axis. At its core, Parameter 1860 functions as a for a given axis
: Manual modification is rare and usually only done during advanced troubleshooting or when migrating parameters from a backup. cti-sumy.com.ua Are you currently troubleshooting a 300 APC Alarm (Ref Position Need Return) or have you recently replaced encoder batteries 64120EN 0i Parameter Manual.pdf
Parameter 1860 monitors this lag strictly during G00 rapid movements. If the physical axis falls behind the commanded position by a value greater than the amount stored in Parameter 1860, the CNC system immediately halts operation. It drops the ready signals, cuts power to the servo amplifiers, engages the mechanical brakes, and displays a on the CRT or LCD screen. Parameter 1860 vs. Parameter 1828 The screen will display Parameter 1860 with separate
FANUC provides the control components, but the machine builder defines the safe physical operating limits based on the mass of the castings and the strength of the ballscrews. Always refer to the specific builder's manual for recommended baseline settings.
When an axis is "zeroed" or re-homed using Parameter 1815 (APZ bit), the system recalculates and updates the value in 1860.
