Illustration 14: Wiring Configuration for SSI and Incremental (TTL or HTL) Encoder
1 Incremental encoder
2 External power supply
5.5.9 SSI Encoder with Incremental or SinCos Track
This example shows the connection of an SSI encoder with incremental (TTL, HTL) or SinCos track on Z,D and A,B as channel 1. The
absolute position is read from the encoder and used as actual position. The incremental/SinCos track is used to compensate for
communication delay and too few absolute position readings due to communication speed.
