Enhances drive performance Improves speed and torque accuracy Short response times Protected against shorts and overloads Compatible with Altivar 71 Supports FVC and FSY modes

Product description

The Schneider Electric VW3A3409 is a universal encoder interface card designed as an option for the Altivar range of variable speed drives. It enhances drive performance by providing precise feedback for motor load state, speed regulation, torque accuracy, and dynamic response. This card is protected against short circuits and overloads, ensuring reliable operation.

This interface card is used for Flux Vector Control (FVC) with sensor feedback on asynchronous motors, or for Vector Control (FSY) with speed feedback on synchronous motors. It operates with encoder power outputs of 5 to 12V and a current of 0.2A. It is compatible with the Altivar 71 drives, offering improved control and efficiency in various motor applications.
