The selector switch is set below or above 100%.
On certain machine tool builder (MTB) configurations, leaving the "Dry Run" switch active, or keeping the Feedrate/Rapid Override dials set to specific diagnostic zones (like a forced 0% or a specialized hardware test position), will throw the WN57 warning.
