Abstract
An actuator, which allows a controller to be commonly applied to a plurality of models without requiring complicated setting operation of control parameters, and is superior in cost effectiveness, reusability and expandability, is provided. And further, a motor unit and a controller unit constituting the actuator are provided. The motor unit is equipped with a motor, a motor drive circuit and a parameter memory, which stores characteristic parameters necessary for controlling the motor. A controller unit, which is adapted so as to be detachable to the motor unit, is provided with a motor control circuit and a communication control circuit. When the controller unit is attached to the motor unit, characteristic parameters stored in the parameter memory are loaded via a communication connector, and used for setting control parameters for the motor control circuit.
