Through the pulse encoder evaluation module on the Micromaster 440, the control circuit is closed. The high-grade vector control in the frequency inverter ensures precise, highly accurate speed control even when sudden load changes occur, and thus offers an important precondition for demanding process functions. A particular advantage is the speed consistency in...
