1. A servo control device for performing control of a servo motor, the servo control device comprising:
a repetitive oscillation command generator that obtains, from an upper control device, only parameter information relating to information of a type of a shape of a command waveform, and numerical information relating to an amplitude and a period of the command waveform and other feature amounts relating to the shape and dimension of the command waveform to generate and output a repetitive oscillation command; and
a command superimposer that obtains a movement command from the upper control device and superimposes the repetitive oscillation command outputted by the repetitive oscillation command generator on the movement command.
