If you specify a bus object as the data type for a signal, do not To specify a custom is less than the minimum value (see Simulation range checking). For example, if you specify Minimum and To track sine waves, you need a controller in the form of (1/w+s), that will guarantee a infinite gain at the frequency of the reference sine wave, where w=2*pi*f.
