Fanuc Wn57 Override Function Is Active __hot__ -

To clear this alarm and return the machine to its standard operating state, you must turn off the override function: Via PMC Parameters Screen: Navigate to the PMC Parameter setting screen on your CNC control. Locate the (倍率) function option. Move the cursor to this setting and change it to "Disabled" Restart the CNC to clear the alarm. Via Keep Relay (K-Address): The override function is often mapped to keep relay Directly changing the value of K906.0 to 0

While categorized as a warning (WN) rather than a hard system alarm (AL), this notification indicates that the machine is operating under modified parameter constraints. It serves as a vital safeguard, alerting operators that standard programmed feedrates or rapid traverses are currently restricted. What is the FANUC WN57 Warning?

Your PMC ladder may use a custom Keep Relay for this function. To locate the exact address: fanuc wn57 override function is active

This condition is typically tied to safety interlocks, maintenance modes, or specific CNC software features. When active, the control system forces the machine to ignore standard G-code velocity commands. Instead, it enforces a pre-defined, safe speed limit. Primary Causes of WN57

Ensure team members recognize that WN57 means the machine is holding itself back for a specific reason—usually an unlatched door or an active setup key. To clear this alarm and return the machine

If you need help disabling a specific override or understanding a custom ladder message related to WN57, let me know your FANUC control model (e.g., 0i-MF, 31i, 18i).

The Machine Tool Builder writes custom PLC/PMC ladder logic to control physical buttons, coolant systems, and safety doors. If a specific system macro variable (such as system variables managing feedrate overrides like #3004 ) has been modified via a custom program or a probing cycle, the control triggers WN57 until that variable is reset to its default state.

On Series 30i/31i/32i controls, this override function can only be active for up to three PMC paths
