A selection device which can reduce labor involved in the setting operation of a controller. The selection device includes an information reception part which receives a machine condition, a storage which stores specification data, a selection part which compares the machine condition received by the information reception part with the specification data stored in the storage to select the electric motor system that meets the machine condition, and a parameter generation part which generates a controller parameter configured to allow a controller which controls the electric motor system selected by the selection part to set in the controller, an operation parameter involved in operating the electric motor system.
