Altivar ATV61/ATV71 - Encoder Interface Cards VW3A3407

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.The common ways of frequency setting of inverters include: giving the keyboard of the operator, giving the signal of the contact point, giving the analog signal, giving the pulse signal and giving the communication mode. These frequencies have their own advantages and disadvantages, which must be selected according to the actual needs
