PROBLEM TO BE SOLVED: To provide an elevator control device capable of reducing installation cost, while reducing shutting-in failure when brake abnormality is caused. SOLUTION: A hoisting machine is arranged in an upper part of a hoistway. The hoisting machine has an electric motor 1 and a sheave 2. A rope 3 is wound on the sheave 2. A car 4 is suspended in an end part of the rope 3. A counterweight 5 is suspended in the other end part of the rope 3. The electric motor 1 is attached with a brake device 6 braking rotation of the electric motor 1. The electric motor 1 is also attached with an encoder 7. The encoder 7 is connected to a control device body 8 controlling operation of an elevator. The control device body 8 has a main control part 8a controlling operation of the whole control device body 8 and an abnormality monitoring part 8b monitoring the hoising machine and the brake device 6.
