Abstract:
An adjustment device for controlling the electric drive of an elevator in connection with a voltage reduction of the supplying network is disclosed. The electric drive of an elevator includes an electric motor and a power supply apparatus of for adjusting the supply voltage of the electric motor. The adjustment device includes a device configured to control the power supply apparatus and also a speed regulator for adjusting the speed of the electric motor. The adjustment device is arranged to determine the output voltage of the power supply apparatus of the electric motor in relation to the permitted maximum value of the output voltage, and the adjustment device is arranged to interrupt the operation of the speed regulator but to continue the operation of the power supply apparatus of the electric motor when the output voltage of the power supply apparatus of the electric motor reaches the permitted maximum value.
