Basic Installation 3-27 MN1902
3.7.3 EnDat (absolute encoder) option - X8
The absolute encoder interface supports both incremental and absolute (multi and single turn)
feedback using SinCos technology. It is possible to read and write information to the encoder.
The absolute encoder connections are made using the 15-pin D-type female connector X8.
Twisted pair cables must be used for the complementary signal pairs e.g. SinA+ and SinA-.
The overall cable shield (screen) must be connected to the metallic shell of the D-type
connector.
