AS7W, AV7W, AG7W
Note the following regarding the encoder interfaces:
The electrical specifications of encoders with the ...W interface (sin/cos + RS485) correspond to the sin/cos signal definitions of the HIPERFACE® interface. However, in the digital interface RS485, they deviate from the HIPERFACE® standard and are only suitable for operation on inverters from SEW-EURODRIVE.
