ABSTRACT:
A door drive control apparatus capable of an accurate detection, without misidentifying an inverse overrun condition, and a door drive control method that improves safety. The door drive control apparatus includes a power converter that supplies power to a door drive linear motor, and operates the power converter by feedback control using a speed detection value and a speed command value of the door, and controls a speed of the door. The door drive control apparatus includes a speed trouble determiner, which outputs a door inverse direction speed trouble signal in the event that the speed command value of the door exceeds either a positive or negative first setting speed, and the speed detection value exceeds a second setting speed of a polarity opposite to that of the speed command value.
