1.6 MOTOR SHAFT ENCODER
This device is optional (not necessary). The Eps-Ac can receive an encoder (CNA #6,
#16, #17 and #7) directly connected to the steering motor shaft. This is an option for a
special application. E.g. fine steering speed control, safety improvement etc. A typical
manual controlled steering with automatic centering does not require an encoder; it just
requires a feedback pot.
