摘要： A drive device of an elevator includes a DC bus, a motor bridge connected to the DC bus for the electricity supply of the elevator motor, which motor bridge includes high-side and low-side switches for supplying electric power from the DC bus to the elevator motor when driving with the elevator motor, and also from the elevator motor to the DC bus when braking with the elevator motor, a control circuit of the motor bridge, with which control circuit the operation of the motor bridge is controlled by producing control pulses in the control poles of the high-side and low-side switches of the motor bridge, a brake controller, which comprises a switch for supplying electric power to the control coil of an electromagnetic brake, a brake control circuit, with which the operation of the brake controller is controlled by producing control pulses in the control pole of the switch of the brake controller, an input circuit for the safety signal to be disconnected/connected from outside the drive device, drive prevention logic, which is connected to the input circuit and is configured to prevent the passage of control pulses to the control poles of the high-side and/or low-side switches of the motor bridge when the safety signal is disconnected, and also brake drop-out logic, which is connected to the input circuit and is configured to prevent passage of the control pulses to the control pole of the switch of the brake controller when the safety signal is disconnected.
