SUMMARY The present invention is regarding to the dual control device on the door and its measures and present invention is purposed to provide recording media for the computer to read the program to realize the dual control device and its method and above measures to control the door successively in spite of failure creation by converting either of the modes into the primary operation mode for door controlling when the failure creation is sensed in the primary operation mode decided from either of the encoder mode or sensorless mode as a primary operation for door controlling. For this matter, present invention includes, a failure sensing part to sense the failure created in the encoder mode and sensorless mode to control the door; a main control part to convert the main operation part and backup control part mutually when a failure is sensed by the primary operation mode by the failure sensing part after deciding either of the encoder mode or sensorless mode as a primary operation mode and another one is decided as a backup operation mode; and a location/speed conversion part to perform the door control by calculating the door moving distance according to the corresponding mode when the operation mode is converted by the main control part. |
