- Description
The Schneider Electric VW3A3423 is a resolver interface module that connects a resolver feedback device to Altivar Process ATV900, Altivar Process Modular and Altivar Machine ATV340 drives for closed-loop position and speed control. Feedback is wired through a female SUB-D9 connector, with ratio options of 1, 3/4, 1/2 or 3/10 and a maximum operating frequency of 12 kHz.

Selection Notes
Specify the VW3A3423 when the motor's feedback device is a resolver rather than a digital or analog encoder. The module supports four transformation ratios (1, 3/4, 1/2, 3/10) to match whichever resolver is installed on the motor, and its 12 kHz maximum operating frequency is the lowest of the encoder interface modules in this range, reflecting the resolver's lower signal bandwidth versus RS422 or HTL encoders.
