Modifying tool change requirements, such as allowing a turret to rotate before axes have reached their home position to save time. Parameter Structure & Addresses
The term in the context of Fanuc keep relays typically refers to system-reserved addresses or bits with specific, non-customizable functions that are critical to the CNC's internal operation or safety. Understanding Fanuc Keep Relays fanuc keep relay parameters exclusive

Use the right arrow (expansion) soft keys until you see , then select PMCPRM or PMC MAINTENANCE . Select the KEEPRL soft key to view the bit table. Input the Data: Navigate to the desired address (e.g., K17). Type the new bit value (0 or 1) and press INPUT . Use the right arrow (expansion) soft keys until
Before assigning a new use to an unused K bit, search the ladder documentation to ensure it is truly unused.
These are commonly used by machine builders to define machine-specific options, such as enabling a chip conveyor, bypassing a door interlock for maintenance, or configuring the Automatic Tool Changer (ATC) pattern .
