8901 Better - Fanuc Parameter

There are two primary settings for Parameter 8901:

This combination is widely considered by Fanuc field service engineers as the “better” configuration for precision, reliability, and speed. fanuc parameter 8901 better

Parameter 8901 is a specific setting in Fanuc CNC systems that allows users to customize and optimize the behavior of their machines. This parameter offers a range of functions that can be tailored to suit specific machining requirements, making it a valuable tool for CNC operators and programmers. There are two primary settings for Parameter 8901:

Once a new fan is installed, you must change PRM 8901#0 back to Once a new fan is installed, you must

In the world of CNC machining, especially when dealing with Fanuc-controlled lathes (including turning centers and mill-turn machines), few settings cause as much confusion—or offer as much potential productivity gain—as .

If you truly want the behavior, combine 8901 with Parameter 4000#2 = 1 (high-speed rigid tapping mode) on 31i-B5 controls.
