Use the arrow keys or type the address (e.g., K5 ) and press to locate the target byte. Examine the 8-bit binary string carefully.

: Enter 1 to enable or 0 to disable the function.

If you switch an exclusive keep relay and the machine immediately throws a 1000+ series manufacturer alarm, check the PMC Diagnostic status ( PMC DGN -> STATUS ). Look at the output coils ( Y signals) to see which safety rungs are actively holding the machine back due to an incorrect configuration.

Mastering Fanuc Keep Relay Parameters (K-Parameters) In the world of FANUC CNC machining, technicians and programmers often need to customize how the machine operates, bypassing specific sensors, activating optional features, or changing machine behavior without rewriting the entire PMC ladder logic. This is accomplished using , commonly referred to as K-parameters .

By understanding how to properly read and modify , you can significantly reduce downtime and customize machine performance to meet specific production requirements. If you're interested, I can:

In the technical hierarchy of the PMC, Keep Relays are just one type of many memory addresses. The typical FANUC PMC memory map includes: Use the arrow keys or type the address (e

If a Keep Relay change doesn't take effect or resets on startup, it's a strong clue: the value is being overwritten by another part of the ladder program. Troubleshooting often involves searching for a for that specific K relay.

Keep Relays (K-parameters) are software switches in the Programmable Machine Control (PMC) that maintain their state (ON/OFF) even after a power cycle. Unlike standard parameters, Keep Relays are "exclusive" because their functions are defined by the Machine Tool Builder (MTB) , not Fanuc itself. Custom Functions:

In FANUC controllers, Keep Relays (K parameters) are a type of within the PMC (Programmable Machine Controller). While standard relays (R) lose their state when power is cut, Keep Relays are backed by battery power or non-volatile memory, so their stored values persist unchanged.
