When button pressed → Set *IT (G8.0) = 1.
[Interlock condition active] ↓ [CNC checks *IT signal] ↓ [*IT = 1] → Override active → Check P8901 → Move allowed on bits set to 1 ↓ [*IT = 0] → No override → All axes remain interlocked (cannot move) fanuc parameter 8901
It allows a technician to keep the machine running while waiting for a replacement fan to arrive. Non-Critical Environments: When button pressed → Set *IT (G8
Let’s explore real-world scenarios where Parameter 8901 is the solution. fanuc parameter 8901
