Abstract
A drive arrangement includes a movable, rotatable rail segment of an elevator system. An electric motor moves the movable rail segment. The drive arrangement is configured to rotate the rail segment about an angle of rotation of less than 360°. An inverter unit provides electrical power to the electric motor and is configured to receive a control command relating to the position of the movable rail segment and provide the electrical drive power based on the control command. The drive arrangement forms two or exactly three drive segments. Each drive segment includes an inverter unit and a coil arrangement, which is supplied with electrical power by the assigned inverter unit. Each inverter unit includes a communication unit, which receives the control command. The communication units are configured to specify amongst themselves a master communication unit and to specify the remaining communication unit as slave communication units.
