4.1.5 EnDat interface
The EnDat interface supports both incremental and absolute (multi and single turn) feedback
using EnDat technology. It is possible to read and write information to the encoder. The EnDat
interface 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. Sin+ and Sin-. The overall cable
shield (screen) must be connected to the metallic shell of the D-type connector. Connector X8
includes a ‘Sense’ pin, which is used to detect the voltage drop on long cable runs. This allows
the MotiFlex
e
100 to increase the supply voltage on pin 12 to maintain a 5 VDC supply at the
encoder (200 mA max). The Sin and Cos channel input circuits accept a nominal 1 V pk-pk sine
wave centered on a 2.5 V reference. Version 2.2 EnDat encoders do not use the Sin and Cos
channels.
