Energy and data supplying module for automation cell, has three lines via which consumers are connected, three phase voltage system supplied to consumer over lines in operating mode, and speed controller provided with determined frequency

摘要

The module (1) has three lines (11), via which consumers are connected. A three phase voltage system is supplied to the consumer over the three lines in an operating mode, where the consumer has units for determination of rotational direction and frequency of the three phase voltage system. The determined information about the direction and frequency are supplied to a speed controller as a reference-rotational direction and reference-rotational speed, respectively. The controller has a converter supplying an electric motor of the consumer. An independent claim is also included for a procedure for operation of a system, comprehensively a supplying module.
