Illustration 13: Wiring Configuration for 2-Track SSI Encoder
1 Encoder
5.5.8 SSI and Incremental (TTL or HTL) Encoder
This example shows the connection of an SSI encoder on Z and D as channel 1 and a 2 track incremental encoder on A and B as
channel 2. An external supply may be needed if the power requirement exceeds the maximum power of the encoder supply (pin
17), or if the 2 encoders require different supply voltages.
