Fanuc Keep Relay Parameters Exclusive May 2026
K parameters
Fanuc Keep Relays, also known as , are a subset of PMC parameters used to control machine-specific functions and maintenance operations. Unlike standard parameters that might reset, Keep Relays are stored in non-volatile memory , meaning they retain their ON/OFF state even after the machine is powered down. Core Functionality
- Attempt parameter edits without authorization — confirm locks work.
- Simulate parameter restores and power cycles — confirm protected values persist.
- Verify machine functions dependent on keep-relay parameters operate normally.

Process Flags
: Tracking ongoing operations, such as signaling that a tool change is in progress so the machine can recover safely after a power failure. Structure and Addressing fanuc keep relay parameters exclusive
