Fanuc Wn57 Override Function Is Active -

: Schedule regular maintenance checks on the CNC machine to prevent issues that might arise from the use of the override function.

The "Override Function" mentioned in this message refers to a specialized tool used by machine tool builders and maintenance technicians to debug the . When this function is active, it allows for the "forced" manipulation of PMC signals—effectively overriding the standard logic of the machine's ladder to test specific behaviors or troubleshoot faulty sensors.

Directly change the keep relay address to 0 . Setting this bit to 0 disables the override function and should clear the WN57 alarm after a system restart . fanuc wn57 override function is active

You can deactivate this function using one of the following methods: : Navigate to the PMC Parameter setting screen. Locate the Override Function (倍率功能) option.

Modern machining centers utilize strict safety interlocks. When setting up a job with the enclosure doors open, operators often turn on a setup switch or a key-switch (such as a hardware override mode) to manually jog axes or spin the spindle at reduced speeds. If this key-switch is left in the setup position, or if the door interlock bypass is active, WN57 will stay triggered. 3. Dry Run or Feedrate Override Switches : Schedule regular maintenance checks on the CNC

Always check the current operation of your machine when this message appears. If the machine is performing a normal cycle, the message can usually be ignored, or it will disappear once the specialized cycle finishes. Directly change the keep relay address to 0

This variable sets the maximum allowed running speed for programs. If the programmed speed exceeds this value, the system automatically limits it.

Unpredictable motion or signal states could lead to mechanical collisions or damage.
