PROBLEM TO BE SOLVED: To manufacture a door control panel at a low cost and shorten the installation work period by providing a main control panel controlling an elevator with a control system different from that for the existing elevator and a new door control device controlling a new door motor. SOLUTION: A main control panel 31 is installed on an engine room floor 32 via a fixing metal 33. A new door control panel 34 storing a door openable zone relay, a lock detecting relay, a travel relay, a door control relay, and a current limiting resistor is fitted on the side face of the main control panel 31. The new door control panel 34 and main control panel 31 are connected by the lead wires 35 guided from the new door control panel 34. Existing components other than a new door motor are used as they are for a door mechanism. The new door motor is changed to variable-voltage variable-frequency control, and its opening/closing actions are made smoother as compared with the control by the existing door motor. |
