Fanuc Keep Relay Parameters Exclusive Jun 2026

Imagine a CNC machining center where:

Operational Rule: These must be exclusive. Setting both to 1 will confuse the proximity switches and cause a chuck open/close alarm. 2. Automation and Peripheral Selection

For engineers or maintenance personnel reviewing this feature, here is how to handle Exclusive Keep Relays effectively: fanuc keep relay parameters exclusive

Press the soft key, then PMC PRM (or PMCPRM ), and finally KEEPRL . Modify the Bit: Find the target K address (e.g., K17).

: Addresses are typically represented in an 8-bit format (e.g., K0.0 to K0.7). Some ranges are reserved for system functions (often K900+), while others are for machine-specific OEM functions. Imagine a CNC machining center where: Operational Rule:

To modify: Use the cursor keys to highlight the specific bit. Type 1 or 0 and press INPUT .

Perhaps the most powerful exclusivity of Keep Relays is their role as the for a mass-produced CNC. Every Fanuc control is a generic computing platform. It is the Keep Relay settings, defined by the machine tool builder (e.g., Haas, Mazak, DMG MORI), that turn this generic controller into a specific lathe, milling center, or press brake. Some ranges are reserved for system functions (often

Press the soft key (on newer controls, press [PMC MNT] or [PMCPRM] ). Select the [K-PARAM] or [KEEP-RELAY] soft key. Step 3: Edit the Binary Bits
