ABSTRACT:
An actuator drive controller is equipped with a power source for supplying power to an actuator; a voltage detector for detecting a voltage of the power source; and a controller for controlling a current supplied to the actuator, based on the voltage detected. When the voltage becomes not more than a reference value, the controller controls the current supplied to the actuator so as to become lower than a current set in advance, depending on consumption power of the actuator, in a case that the consumption power of the actuator is not less than a specified value set in advance.
