Use the cursor to select the specific K-address. Addresses are read from right to left (Bit 0 is the far right, Bit 7 is the far left). Enter Value: Type 1 for ON or 0 for OFF and press Input .

High-pressure coolant stops working randomly, but no alarm triggers. Debugging this takes hours because the ladder shows the same bit in two unrelated rungs. fanuc keep relay parameters exclusive

Default to a safe state, ignoring both commands until the conflict is resolved. Use the cursor to select the specific K-address

Some machines require the Emergency Stop to be depressed or the PMC to be stopped before certain system bits can be modified. Fanuc PMC - Keep Relays (K Parameter) Explained in English High-pressure coolant stops working randomly, but no alarm

In the intricate ecosystem of FANUC CNC systems, the distinction between volatile memory and non-volatile memory is the line between a machine that remembers its purpose and one that resets to oblivion upon reboot. At the heart of this distinction lies the "Keep Relay" (often designated by addresses beginning with the letter 'K'). While standard Relays (R, D, or E addresses) are essential for the logical flow of a program, Keep Relay parameters occupy an exclusive and critical tier within the ladder logic architecture. They serve as the system’s long-term memory, preserving vital operational states and configuration settings even when power is removed. Understanding the exclusive nature of Keep Relay parameters is essential for any engineer or technician aiming to maintain system integrity and prevent catastrophic data loss.

Machine Tool Builders (MTBs) use Keep Relays to configure the physical attributes and operational logic of the machine. Common applications include:
