Fanuc Parameter 8901 Better !!link!! 【PC】

The “better” setting eliminates mechanical hysteresis and improves long-term consistency.

If a tool is burying its way through a deep pocket or an intricate profile, a sudden loss of feed rate while the spindle coast down leaves an unsightly gouge. In worse cases, it snaps the tooling inside the part. Transitioning to a warning-only state gives the operator time to hit standard cycle stops safely. 2. Shifts Crisis Management to Planned Maintenance fanuc parameter 8901 better

In such a scenario, a machine shutdown could mean costly downtime and missed deadlines. By temporarily setting , you can bypass the alarm and resume production. However, this is a calculated risk, and FANUC manuals across multiple system models (0iC, 0iD, 16, 18, 21i, 210i) explicitly warn that this action is only to be used as a temporary measure to keep the machine running while you source a new fan. Transitioning to a warning-only state gives the operator

Before we discuss why it is "better," we must understand the mechanic. By temporarily setting , you can bypass the
