A motor control device controlling an inverter to control an electric motor, includes a plurality of function sections, a voltage command generating section generating a d-axis voltage command and a q-axis voltage command, a voltage operational processing section, an input current operation section, a speed information generating section estimating a rotational speed of the motor based on at least one of a motor constant, a positional information generating section delivering positional information about a rotor, and a processor executing control software set by a user or a manufacturer. At least a part of the function sections are configured by hardware. The function section configured by the hardware is given at least one parameter retaining section. The parameter retaining section is configured so as to be readable/writable on the processor. The function section is configured by the hardware so as to be operated in a predetermined sequence.
