will disable the function and should clear the WN57 message. Why This Message Appears Debugging/Testing:
Physically turn each dial away from 100%, then firmly click or seat them back exactly onto the mark.
The spindle speed override knob is dialed away from 100%. Dry Run Mode ( DRNcap D cap R cap N
In these cases → the warning.
The alert protects your machine, tools, and workpieces. It reminds you that the machine is not running at its fully programmed speed. When debugging this alert, check your operator panel knobs first, verify safety door settings second, and check PMC diagnostics last if the message refuses to clear. If you want to troubleshoot further, tell me: What FANUC control model are you using (e.g., 0i-F, 31i)?
Whether this alert occurs or completely at random.
In many systems, this function is tied to a specific keep relay. Setting K906.0 to "0" will often immediately deactivate the override function and clear the WN57 message. fanuc wn57 override function is active
While the specific implementation varies by machine tool builder, "WN57 Override Function is Active" typically relates to [1]. Here are the most common scenarios: 1. Spindle Override/Override During Rigid Tapping
Find the entry labeled or "倍率" (in some regional settings). Change the status from "YES" (or 1 ) to "NO" (or 0 ). Method 2: Adjusting Keep Relays (K-Addresses)
The Machine Tool Builder defines exactly what triggers WN57 within the PMC ladder logic. A specific G-byte (interface signal sent from the PLC to the CNC) is turned on when certain conditions are met, clamping the override values to a safe threshold.
