A control device is provided, which is capable of allowing a load factor to be understood easily while obviating reliably errors in selecting a rated value of an electric motor driven by a driving device without requiring any unnecessary labor in management of the rated value. The control device includes: an acquiring unit that acquires via a communication line reference value data indicating predetermined reference values for a torque and a rotating speed, which are parameters indicating an operating state of an electric motor, from a driving device that controls driving of the electric motor; and a calculating unit that acquires via the communication line present value data indicating one of a physical quantity, which is a value of the respective parameters measured in the electric motor during operation and a ratio of the physical quantity to the reference value from the driving device, and calculates the other one of the physical quantity and the ratio from the present value data and the reference value data.
