The override function is directly linked to the system address .

This Fanuc message indicates that a customized Override Function (WN57)

Navigate to the screen displaying current feed rates and spindle speeds.

Check the physical control panel of the machine. Turn both the feedrate override dial and the spindle speed override dial exactly to the position. On many FANUC panels, this aligns the dials to the top-vertical position. 2. Deactivate Dry Run Mode fanuc wn57 override function is active

If the dials are at 100% but the message persists, check the button. If the Dry Run light is illuminated, press it to turn it off. Dry Run forces the machine to use manual feedrate overrides instead of the programmed G-code values. 3. Clear Manual Feed Generation

is the specific hexadecimal or decimal identifier assigned by the machine tool builder (MTB) or FANUC's system software to signify an active override condition.

While the WN57 warning will not usually stop a program mid-cycle, leaving it active can cause several secondary issues: The override function is directly linked to the

当您正在操作一台配备FANUC数控系统的机床时，控制器屏幕上突然弹出一条**WN57“OVERRIDE FUNCTION IS ACTIVE”**的报警信息。这并非机床发生了机械故障，也不是硬件损坏，而是一个来自PLC（可编程逻辑控制器）的“警戒”信息，它在提醒您：机床的PMC程序正运行在一个特殊的调试模式中。

The override function is specifically identified by FANUC as "for debugging only," and FANUC explicitly instructs users to disable it before shipping machines.

Operating the spindle above or below the programmed 100% value will often trip this warning. 3. Rapid Traverse Override is Engaged Turn both the feedrate override dial and the

Always include safety blocks at the beginning of your G-code programs (e.g., G40 G80 G90 ) to cancel any lingering modal states.
