Typically reserved for builder-defined machine sequence logic.
) are reserved for Fanuc system functions, such as enabling ladder editing or controlling how data is backed up to flash memory.
After changes, return the setting to 0 to prevent accidental modifications. Common Exclusive Use Examples Get to know how to change the Keep Relay!
The primary "exclusive" role of keep relays is to act as software-driven switches that bridge the gap between fixed CNC parameters and the machine tool builder's (MTB) custom ladder logic.
Changing these parameters requires cautious access to the PMC maintenance screens. Set the machine to MDI mode .
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
Often designated as "System Keep Relays" that handle internal CNC-to-PMC communication states. How to Modify Keep Relay Parameters
Select the or [PMC MNT] soft key, then navigate to [KEEP RELAY] . Search and Edit:
Keep relays are organized by address (e.g., K0, K1, K2) and then by individual bits (0 through 7).
Move the cursor to the specific bit and enter the new value (0 or 1).
