To provide an abnormality controller for an elevator which supplies a control voltage from one side to the other side when there is a trouble in either a control voltage of the door or a control voltage of the other device and normally performs a stop operation to the nearest floor.
The elevator abnormality controller has a door controller 9 controlling a door open and close motor 1, a door control voltage generator 5 supplying a direct current to the door controller 9, an electrolytic capacitor 7 connected between outputs of the door control voltage generator 5, a relay 8 detecting that a voltage of the door control voltage generator 5 is lower than a predetermined reference voltage, a device controller 14 controlling other devices other than the door, a device control voltage generator 10 supplying a direct current to the device controller 14 at the same voltage as that of the door control voltage generator 5, open and close means 20a1 and 20a2 for opening and closing power input parts of the door controller 9 and the device controller 14, and a voltage supply relay closing the open and close means 20a1 and 20a2 and connecting the device control voltage generator 10 to the door controller 9 when the relay 8 detects a voltage decrease of the door control voltage generator 5.
