This variable directly controls the main speed override of the system. When $MCR.$GENOVERRIDE = 80 , the speed becomes 80% of programmed values.
The alarm appears in the PMC alarm section of your FANUC control system, distinguishing it from CNC alarms, servo alarms, or spindle alarms.
Maintain clear documentation of all parameter changes made during maintenance or debugging activities.
To disable through setting parameters:
Include override function activation in maintenance logs.
K parameters are keep relays that serve as internal memory bits for machine builders and integrators to customize machine behavior. While standard user K parameters exist up to K99, the K900-K999 range (often called "system K parameters") controls advanced PMC functions.
: For intricate parts that require precise machining conditions, the override function can be used to fine-tune the machine's performance. This ensures that the final product meets the required specifications. fanuc wn57 override function is active
在FANUC生态系统中，“倍率/Override”一词具有多重含义，很容易造成混淆。为了帮助您清晰地区分，以下通过一个表格总结其不同的应用场景：
Consult your specific machine tool builder manual (e.g., your ROBODRILL instruction manual) to locate the exact Keep Relay assigned to "Override Functions." Switch the control to , enable Parameter Write (
If the physical dials are at 100% and the warning persists, a software flag is likely locked in the PMC memory. Press the hard key on the FANUC panel. This variable directly controls the main speed override
The most frequent culprit is the manual Feedrate Override dial on the operator panel. If an operator slows down a feed movement during a setup or dry run (e.g., dialing down to 50%) and forgets to turn it back to 100%, the WN57 warning will trigger to flag the reduction. 2. Spindle Speed Override Switch is Active
If you are actively proving out a new program or performing maintenance, you can safely ignore the WN57 warning. It is doing its job by reminding you that overrides are active. If Unintentional: Return all manual dials to
error if too many paths (typically four or more) are being overridden simultaneously. Course Hero Recovery Steps Maintain clear documentation of all parameter changes made
