Fanuc Parameter 1860 May 2026

A: OEMs often set 1860 for maximum stiffness to guarantee tool change reliability, even at the cost of a slight vibration. You can usually reduce it by 10-15% for smoother operation, but confirm with them first.

If you have ever encountered an alarm such as "PS0405 – No Spindle Orientation" or noticed that your tool change arm misses the pull studs by a few degrees, you have likely entered the realm of Parameter 1860. This article serves as your definitive guide. We will cover what Parameter 1860 is, how it works, how to calculate its value, step-by-step modification procedures, common troubleshooting scenarios, and best practices from seasoned service engineers. 1.1 The Technical Definition Fanuc Parameter 1860 (often listed in manuals as N1860 or PRM 1860 ) is a position gain parameter specifically associated with the spindle orientation circuit . In simple terms, it tells the spindle drive (usually a Fanuc Alpha i series or earlier digital spindle amplifier) how aggressively to correct positional errors when orienting the spindle to a specific angular position (e.g., 0°, 90°, 180°, or 270°). fanuc parameter 1860

A: Yes, on Robodrill with Fanuc 31i-B5. Default is typically 1200 for BT30 spindles. Conclusion: The Art of the Perfect Stop Fanuc Parameter 1860 may appear as just another number in a sea of thousands. But as we have seen, this unassuming integer is the difference between a tool change that sings and one that stumbles. From the physics of gain to the practicalities of field tuning, understanding 1860 empowers you to reduce cycle times, eliminate alarms, and protect your spindle amplifier from unnecessary stress.
