Fanuc Keep Relay Parameters Exclusive //top\\ | TRUSTED × 2026 |

Builders use K-relays to toggle features like tool changers, door interlocks, or coolant options. Non-Volatile:

Press the right arrow menu key (▶) until you see or PMCMNT (PMC Maintenance). Select KEEPRL (Keep Relay). Edit the Keep Relay:

measure elapsed time for sequences such as clamp-hold delays or spindle stabilization periods. When a timer counts down or up, it automatically resets to its preset value. Timers are volatile in run-time state but non-volatile in preset value—their accumulated current value resets at power‑off, but the preset value remains. fanuc keep relay parameters exclusive

Understanding FANUC Keep Relays: The Guide to Exclusive Parameter Logic

Remember that when parameters are mutually exclusive, changing one bit may have a domino effect on the spindle, the tool magazine, or the coolant system. Builders use K-relays to toggle features like tool

Use the arrow keys to navigate to the exact keep relay address and bit you want to change (e.g., K5.4). Type the new value (1 for ON, 0 for OFF) and press . Finalize and Reset: Revert the Parameter Write Enable (PWE) back to 0. Press the RESET key to clear the parameter write alarm.

Temporarily shielding external alarms or bypassing sensors (like a faulty conveyor rotation sensor) during troubleshooting. Edit the Keep Relay: measure elapsed time for

K0000.0 to K0099.7 (Exact ranges vary by FANUC control series like 0i-F, 31i-B, etc.).

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
