Abstract: A determination of the loading state of an elevator system and also a method for determining the loading state of an elevator system is described. The elevator system includes an elevator car and also a motor drive for moving the elevator car. The loading state of the elevator system is determined on the basis of the position deviation of the elevator motor that occurs during the determination of the loading state.

Abstract: An elevator system and a method for monitoring the operating condition of an elevator system are provided. In the method, samples are taken of the control signal of the drive device of the elevator, from the series of samples taken a frequency component is determined that is characteristic to the part of the elevator assembly driven with the drive device, and also the operating condition of the part of the elevator assembly is monitored on the basis of the determined frequency component.

Abstract: The invention relates to an elevator system and also to a method for ensuring the safety of an elevator system. The elevator system comprises a driving member (1) and also a hoisting means (3), which engages with the aforementioned driving member (1) by frictional traction. The elevator system comprises traction determination means (4, 5, 6A, 6B, 7) for determining the traction of the driving member (1), and the elevator system comprises a control circuit (4), which is configured to start a procedure ensuring the safety of the elevator system after the traction determination means (4, 5, 6A, 6B, 7) have detected that the traction of the driving member (1) has weakened.

Abstract: The invention concerns a method and an apparatus for controlling a three-or-more-phase motor driven by a frequency converter. In the method, a change-over switch of the frequency converter is controlled to a continuously conducting state and at the same time the phase voltages or phase currents of the other phases are controlled by switching the change-over switches in those motor phases at a switching frequency substantially higher than the frequency of the fundamental wave of the phase voltage or phase current. The apparatus comprises in conjunction with the frequency converter a number of change-over switches, at least one change-over switch for each motor phase. The change-over switches comprise controllable change-over contacts. The apparatus further comprises in conjunction with the frequency converter means for determining the motor phase currents and means for controlling the change-over contacts.

Abstract: The invention relates to a frequency converter (1), comprising a load bridge (2) and also a control (3) of the load bridge, for supplying electricity between the load bridge (2) and an electric machine (4) connected to the load bridge; which frequency converter comprises a determination (5) for at least one electrical parameter of the aforementioned electric machine, and which frequency converter comprises a determination (6) for the position of the rotor of the electric machine. According to the invention a load bridge (2) is fitted to supply a first alternating electricity excitation signal (7) to the aforementioned electric machine (4), which first alternating electricity excitation signal is formed in relation to the electrical angle (18) of the electric machine. The frequency converter is fitted to determine a first alternating electricity response signal (9,16) corresponding to the aforementioned first alternating electricity excitation signal (7), and the position of the rotor is determined on the basis of the first alternating electricity response signal (9,16).

Abstract: The invention relates to a drive system (100) for driving an electric motor (110). The drive system (1009) comprises a drive control unit (120) and a frequency converter (130) comprising a speed controller (140). The drive control unit (120) is configured to: define a speed reference (210) of the electric motor (110); preset operating parameters of the speed controller (140) to provide a first response time of the speed controller (140), before a drive of the electric motor (110) is initiated; adjust at least one operating parameter of the speed controller (140) to provide a second response time of the speed controller (140), after the speed of the electric motor (110) reaches a constant speed, wherein the second response time is slower than the first response time; and readjust the at least one operating parameter of the speed controller (140) to provide the first response time, before a deceleration from the constant speed is initiated. The invention relates also to a method for controlling the drive system (100) for driving the electric motor (110).
