Type the exclusive value ( 0 or 1 ) and press the softkey. Step 4: Relock the System Return to the OFFSET/SETTING screen. Change PARAMETER WRITE back to 0 . Press RESET to clear the PWE alarm.

Exclusive Keep Relay configurations are most frequently found in versatile machine platforms that support multiple physical configurations. 1. Tool Changer (ATC) Selection

Think of them as the "dip switches" or "configuration jumpers" of the digital CNC world. They control high-level machine behavior, such as:

A Keep Relay (often denoted as K0, K1, K2... up to K999 depending on the control model) is a used within the PMC (Programmable Machine Controller) ladder logic. Unlike standard internal relays that lose their state when power is cycled, Keep Relays are non-volatile. They retain their state (0 or 1) even when the entire machine is shut down.

: Values are stored in non-volatile memory, ensuring that settings like a chip conveyor's "on" status or safety bypasses persist after a restart. Type the exclusive value ( 0 or 1 ) and press the softkey

Use the arrow keys or type the specific address (e.g., K0005 ) and press (Search). Position your cursor over the exact bit you need to alter.

The machine builder holds the key to the custom K parameters (K0–K99), while the end user is generally granted safe harbor in the upper standard ranges. Understanding these tiers of exclusivity allows a technician to confidently diagnose issues without fear of "bricking" their controller. By respecting the boundaries of the System Keep Relays and mastering the Safe, User, and Builder zones, you truly take command of the FANUC controller's full potential.

In FANUC CNC and robot controllers, are bit-type non-volatile memory elements used to store machine-specific configuration settings. Some Keep Relays have exclusive, pre-defined functions — meaning their behavior is fixed by FANUC and cannot be reassigned by the OEM or end user.

Exclusively used for PMC management software data and should not be used for custom machine sequences unless specified by Fanuc.

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

In more complex setups, an entire byte (8 bits) of a keep relay might govern a specific subsystem, such as an automatic tool changer (ATC) or an indexing table. Within that byte, only one specific bit is allowed to be active ( 1 ) at any given time. Activating more than one bit simultaneously creates a logic conflict, resulting in PMC alarms or unexpected machine behavior. Common Applications of Exclusive Keep Relays
