Serial EnDat output signals
Being a bi-directional interface, the EnDat interface (Encoder Data) of the absolute encoders can output
absolute position values as well as request or update information stored in the encoder. Owing to serial
data transfer, 4 signal lines are sufficient. The data transfer mode (position values or parameters) is
selected via MODE commands which the encoder receives from the subsequent electronics. The data
transfer is synchronized with the CLOCK signal given by the subsequent electronics.
