Analog controlled drives with PROFIBUS: experimental results

Industry modernization deals with new technologies application in present plants. New technologies are nowdays mostly based on industrial communication networks. This paper describes usage of existing analog controlled motor drives in industrial communication network PROFIBUS. Laboratory setup is done with Siemens Simatic S7-300 equipment, together with analog controlled inverter and permanent magnet synchronous motor. Measurement, control and monitoring of drive is realized by programmable logical controller (PLC) connected over industrial communication network.
