Fanuc Parameter 1860 Today

: Swapping out a servo motor or a rotary encoder changes the alignment of the internal pulse tracks. A new home position must be set, which updates Parameter 1860.

The role of parameter 1860 varies across FANUC control families. The following table summarizes the documented applications:

To understand 1860, you must first understand the two-phase homing sequence on a FANUC control:

I can then help identify the correct procedure for your situation. Fanuc 21i-T Parameters - Industry Arena fanuc parameter 1860

Setting FANUC parameter 1860 requires a basic understanding of the FANUC CNC system and its parameterization. Here are the steps to set parameter 1860:

The behavior of Parameter 1860 and 1861 is directly controlled by the , which is bit #6 of Parameter 1815. This bit determines whether the reference point value is automatically renewed or remains static.

The most widespread use of Parameter 1860 is in the management of reference points, particularly for rotary axes. Let's break this down in detail. : Swapping out a servo motor or a

: Always ensure that changes to parameters like 1860 do not compromise the safety of the machine operator or the integrity of the machine itself.

If you need to know the specific parameter settings for your particular machine tool, knowing the , model , and controller type (e.g., FANUC 18i-MB) will help me give you more precise instructions. Series 16i-18i-MODEL B - Parameter Manual.pdf - Drivesul

The following table summarizes the primary functions of Parameter 1860 across different FANUC control series: This bit determines whether the reference point value

In the world of FANUC CNC systems, Parameter 1860 is a critical, though often misunderstood, data field that serves as the digital link between the machine's physical location and its internal coordinate system. For technicians and engineers, mastering this parameter is essential for maintaining the high-precision "memory" of a machine tool. The Role of Absolute Position Detectors

On older controls (0i, 16i, 18i, 21i), 1860 may be integer only; newer controls allow decimal values for fine adjustment.
