VW3A3407 Schneider Electric Option card for use with Altivar 71 Series

VW3A3407 Schneider Electric Option card for use with Altivar 71 Series. Encoder interface cards are used for Flux Vector Control operation with sensor (FVC mode) for asynchronous motors, or for Vector Control operation with speed feedback (FSY mode) for synchronous motors.
For asynchronous motors, in the other control modes (voltage vector control, voltage/frequency ratio), encoder interface cards improve static speed accuracy.
