Fanuc Keep Relay Parameters Exclusive ⭐

Ensure specific relay (keep-relay) parameters persistently remain enabled/unchanged and are not overwritten by automatic parameter loads, backups, or other user changes on FANUC CNC controls.

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. fanuc keep relay parameters exclusive

Builders use keep relays to "use or not use" specific machine units, such as enabling/disabling a chip conveyor, high-pressure coolant, or an automatic door. System Configuration: Certain keep relays (specifically Unlike standard internal relays that lose their state

In Fanuc CNC systems, are software-based latching relays within the Programmable Machine Control (PMC) that maintain their state (ON or OFF) even after the power is cycled. These parameters are primarily used by machine tool builders to enable or disable specific machine options, bypass sensors for maintenance, or configure custom logic without rewriting the entire ladder program.
