- Description
The Schneider Electric VW3A3422 is an analog encoder interface module that connects a SinCos Hiperface or 1 Vpp encoder to Altivar Machine ATV340, Altivar Process ATV900 and Altivar Process Modular drives. It supplies 5 V, 12 V or 24 V DC to the encoder and reads position feedback through a female high-density SUB-D15 connector, up to a 100 kHz operating frequency.

Selection Notes
Specify the VW3A3422 when the motor's feedback device is an analog SinCos Hiperface or 1 Vpp encoder rather than a digital RS422/EnDat type. Its lower 100 kHz maximum operating frequency reflects the analog signal path and suits standard servo feedback loops on ATV340 and ATV900 drives.
