摘要：
An apparatus for controlling an elevator door based on controlling an electric motor for driving the door with a microcomputer and resetting the microcomputer when the power supply fails has a voltage monitor which detects the power source voltage and a braking circuit forcibly brakes the motor if the power source voltage detected by the voltage monitor is lower than a prescribed voltage. The motor is forcibly braked when the detected power source voltage is between the prescribed voltage and the lower limit of the range of voltages at which the microcomputer can operate.
