Fanuc Keep Relay Parameters Exclusive !exclusive! -

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

For troubleshooting, keep relays can be used to bypass physical sensor alarms or simulate signals (like a "work gap sensor") during machine setup. Address Structure and Bit Significance

Exclusively used for PMC management software data and should not be used for custom machine sequences unless specified by Fanuc. fanuc keep relay parameters exclusive

Often designated as "System Keep Relays" that handle internal CNC-to-PMC communication states. How to Modify Keep Relay Parameters

Keep relays are organized by address (e.g., K0, K1, K2) and then by individual bits (0 through 7). Fanuc keep relay parameters, denoted by the address,

After changes, return the setting to 0 to prevent accidental modifications. Common Exclusive Use Examples Get to know how to change the Keep Relay!

Builders use keep relays to "use or not use" specific machine units, such as enabling/disabling a chip conveyor, high-pressure coolant, or an automatic door. System Configuration: Certain keep relays (specifically Address Structure and Bit Significance Exclusively used for

Typically reserved for builder-defined machine sequence logic.
