Abstract: A control system for controlling a shared variable frequency drive for operating more than one mechanical systems of a grain bin. The control system includes at least one processor circuit that is configured to operate the shared VFD in both a first mode, wherein operating in the first mode results in operating a fan assembly of the grain bin, and a second mode, wherein operating in the second mode results in operating an unload sweep assembly within the grain bin.
