consumption. Usually there was something specific prompting the question — such as thermal dissipation being an issue. We learned that it’s not always the posed question needing addressing — but something related to it. So we began using technology and our silicon experience to solve problems in new ways. On connected motion and servos and drives, several parts are involved in the sequencing. There’s the processor — the system brains — and the PWMs driving the signal … as well as the isolated DESIGN WORLD

gate drivers (IGBTs) … and the measurement of the currents returning — for a complete control-loop algorithm. We’ve worked to optimize many of these. But from a system point of view, communications have become more critical — and deterministic Ethernet is increasingly a part of these communications. Even in factory control and process automation where 4-to-20 mA and fieldbuses have reigned for a long time, Industrial Ethernet is coming to the floor … in an array of standards.
