Abstract
An apparatus for controlling drive of a plurality of actuators is provided. The apparatus comprises a plurality of drive circuits respectively driving the actuators and respectively mounted on a plurality of circuit boards each formed as a module for driving each of the actuators. Each module is detachable to the apparatus. The apparatus comprises a plurality of capacitors each mounted on each of the circuit boards. The capacitors have capacitances different from each other. The apparatus also comprises a charging unit charging the capacitors, a measuring unit measuring a period of time during which a charging potential at each of the capacitors rises up to a predetermined potential, a module type determining unit determining a type of each of the modules in accordance with the period of time for each capacitor measured, and a unit for taking countermeasures depending on a determined result.
