An elevator control apparatus which, when a power failure of the A.C. power source is detected, effectively and usefully uses stored power in a power accumulator and when the A.C. power source is restored, returns an elevator back to the original service to make proper operation possible. The control system includes a control for, when a power failure is detected with a power failure detector, supplying power from the power accumulator to an inverter, to control circuits, and to an illumination circuit of the elevator with a charge/discharge control circuit to continue the operation of the elevator. |
