Baldor Flex+DriveII Installation Manual

Basic Installation 3-27MN1902
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 .
