  • Patent number: 10167172
    Abstract: A passenger conveyor may include a conveyor motor controlled by a conveyor control via a motor drive, the motor drive including a frequency converter with a rectifier bridge, an intermediate DC circuit and a converter bridge connected with the conveyor motor. The rectifier bridge is configured to be connected to mains via at least one relay, which relay is controlled by the conveyor control, the conveyor comprises a deep sleep mode, in which the frequency converter as well as at least a major part of conveyor control is switched off. The intermediate DC circuit forms the power supply for the conveyor control. During the activation of the deep sleep mode, the conveyor control is configured to open the relay, whereby at least one signal circuit of the conveyor is configured to remain powered at least during the deep sleep mode.

  • Patent number: 9975730
    Abstract: In a method for performing a balance check with an elevator, a power model of the elevator is established, including the motor power fed to the motor (PM) and power parameters of the motor and the moved components in the hoistway (PK, PP, PFr, PCu, PFe), a test run of the elevator is made, mid motor power values for the up and down direction are determined, i.e. the power fed to the motor at the instant when the car is moving through the middle of the travelling path of the elevator in up and down direction with constant velocity, the difference between the mid power value in up and down direction is determined, the balancing weight difference is obtained from said mid power value difference. This method allows an easy determination of the elevator balance preferably in course of modernizations of an elevator system with a new elevator motor.
