: It works in conjunction with Parameter 1815 (APC and APZ bits), which tells the system whether an absolute encoder is present and if the zero-point has been established. When 1860 Matters

While often factory-set by the Machine Tool Builder (MTB), it typically represents a distance (often in microns or pulses). If you must adjust it, always refer to your specific Fanuc Parameter Manual for the correct unit of measure (e.g., 0.001mm).

If Parameter 1860 is too :

A: Yes, on Robodrill with Fanuc 31i-B5. Default is typically 1200 for BT30 spindles.

Based on typical Fanuc parameter documentation and user discussions:

The specific steps to set parameter 1860 can vary slightly depending on the FANUC CNC system model. Generally, the process involves:
