8901 Better — Fanuc Parameter

If you would like to proceed with deeper troubleshooting, tell me your (e.g., 0i-MC, 0i-TD, 31i), and I can help you confirm the exact replacement fan part numbers or structural diagrams for your system. Share public link

alarm on various CNC systems, such as the 0i-C and 0i-D series. Specifically, modifying

Often, the 701 alarm occurs because the heatsink behind the amplifier is "caked in goop," preventing effective cooling. Use compressed air to clean it thoroughly. fanuc parameter 8901 better

Exposes open CNC circuitry to airborne coolant mist, metallic dust, and debris. Managed, short-term shifts while waiting for parts.

Tool nose radius compensation is critical for precision tapers, arcs, and chamfers. When 8901 = 1, TNR comp interacts with the sum of geometry and wear, which means your cutter compensation behaves predictably when you adjust for size. If you would like to proceed with deeper

Locate bit #0 (usually the right-most digit). Change the value to . Disable PWE:

Its primary function is to determine how the control decides where the machine’s reference position (zero return) is after power-up, specifically regarding grid shift calculations and the use (or ignoring) of the deceleration dog (limit switch). Use compressed air to clean it thoroughly
