Parameter 1860 - Fanuc

Parameter 1860 is a . Its primary function is to maintain the absolute position data provided by the encoder. When a machine uses an absolute encoder, it doesn't need to be "homed" or "zero-returned" every morning; instead, it reads the value stored in this parameter to determine its exact location.

In the world of CNC (Computer Numerical Control) machining, few things are as critical—or as misunderstood—as spindle orientation. Whether you are performing rigid tapping, automatic tool changing (ATC), or using a C-axis indexing feature, the spindle must know exactly where it is in rotational space. For Fanuc-controlled machining centers and lathes, one parameter stands out as the gatekeeper of this function: . Parameter 1860 is a

Some high-end FANUC controls (31i-B5, 30i-B) offer an optional that bypasses the dog entirely. In that mode, Parameter 1860 is ignored. However, standard dog-type return remains the default. Gary clapped her on the shoulder
