Fanuc keep relay parameters, denoted by the address, are non-volatile memory bits used within the Programmable Machine Controller (PMC) to manage machine-specific logic and system configurations. Unlike standard internal relays (R) that reset when power is lost, keep relays retain their state (0 or 1) even after a machine shutdown, making them essential for persistent settings like tool change flags, interlocks, and optional hardware toggles. Core Functions of Keep Relay Parameters Key in the desired K-address (e
