K0 through K15 are typically reserved for the machine sequence (builder-defined), while K16 and higher are often reserved for system management. 2. Common Keep Relay Examples
Are you trying to (e.g., a 4th axis, a bar feeder, or a coolant system)? What specific alarm is the machine currently displaying?
Activating or deactivating features like tailstocks, steady rests, or chip conveyors.
A FANUC factory technician demonstrated that setting K17.1 = 1 (a system-exclusive parameter) enabled a hidden menu button on the SYSTEM/PMC screen allowing ladder diagram backup and system parameter loading. This technique works across 16‑series and 18‑series controls.
Bypassing a faulty sensor temporarily to keep the machine running.
Move the cursor to the new exclusive option bit, type 1 , and press .
A: The number varies by control model and PMC type. Many systems define K0 through K39 and include additional data tables such as C0 through C199 for counters.
In Fanuc CNC systems, (identified as K parameters ) are non-volatile internal relays within the Programmable Machine Controller (PMC) that retain their state even after the machine is powered off.
For System Keep Relays (K900+), the values may not be visible or changeable unless the machine is in an Emergency Stop state. Get to know how to change the Keep Relay!
Keep Relays are typically organized into an 8-bit octal system (bits 0 through 7).
FANUC keep relay parameters (K parameters) provide essential configuration flexibility, enabling everything from minor operator preference toggles to major machine behavior control. The "exclusive" nature of the K17–K19 and K900–K927 ranges means certain functions are reserved strictly for system-level management.
that sounded like a heavy bolt sliding home. The "Cycle Start" lamp flickered to life. Elias didn't know who "The Apprentice" was or why they needed a lock, but he’d just found the one bit of data that refused to be forgotten.
