The NominalRawMaterialRate is used as the PV for each feeder when the Mill is stopped and a Recalculate Set Points are done.
Per default the NominalRawMaterialRate is set to half the feeder capacity, but it is recommended to set it to represent normal production numbers to ensure a more correct calculation during mill stop.
The setting for the NominalRawMaterialRate can be found as shown on the two images below - remember to schroll to the right to find the numbers.
