Digital processing

close

Multiple sensors and sensorless digital motor control algorithms are used to drive the appropriate PWM signals to the power stage by computing the feedback received from the position sensing/current and voltage sensing blocks. Other digital processing functions include software programmable, multiprotocol Ethernet and Fieldbus, as well as software programmable multiprotocol encoder feedback.
