Fanuc Keep Relay Parameters Exclusive Page
Modifying keep relays can fundamentally change how a machine tool operates. Keep these rules in mind:
Press the SYSTEM button, then press the soft key PMC MAINT (or PMC MAINTENANCE).
These higher-range addresses are often reserved by Fanuc for system-level functions. For example, K928 and K929 may control critical safety circuit interfaces. Unlike user bits, these are often "exclusive" to the system logic and should only be modified under direct manufacturer guidance. Common Uses for Exclusive Logic
Turning on features like a robot interface, automatic door, or part probe. fanuc keep relay parameters exclusive
If you need help configuring a specific exclusive function on your machine, please let me know: What is the ? (e.g., 0i-TD, 31i-Model B)
When we talk about , we are referring to the specific, often system-critical K-bits ( K0.0cap K 0.0 K999.7cap K 999.7
Once write access is enabled, the editing process is straightforward: Modifying keep relays can fundamentally change how a
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
Defining machine-specific behaviors set by the builder.
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 . For example, K928 and K929 may control critical
