PROBLEM TO BE SOLVED: To provide an elevator controller which can minimize an influence of noise and has high reliability, in the controller provided with an inverter mounted at a distant position from a main controller 3. SOLUTION: A main controller 3 which prepares command signals for the speed control and torque control of an elevator is mounted inside a three-way frame 2A near the topmost floor hall door, and an inverter controller 4 which controls driving of the motor M of a hoist 9 based on a command signal from the main controller 3 is mounted on the top of a topmost floor hoistway. The main controller 3 and the inverter controller 4 are connected through a light transmission cable 12 to transmit the command signal with a light signal. |
