METHOD FOR TRANSMITTING DATA BETWEEN A PUMP UNIT AND A CONTROL DEVICE, AND AN APPROPRIATELY DESIGNED PUMP SYSTEM

摘要

The invention relates to a method for transmitting data between a pump unit (2) and a control device (8), where the pump unit (2) is connected to a frequency converter (14) via at least one electrical supply line (10) for the purpose of supplying power, with the data transmission taking place via the electrical supply line (10) and a data transmission signal (34) received from the pump unit (2) or the control device (8) being evaluated only in low-interference regions of a carrier signal (22) formed by a supply current, and also a pump system designed to carry out this method.
