The table below and the figure give an example of how to connect
the Stegmann ATM 60-A encoder to the TJ1-FL02.
/i
EnDat
You can configure the TJ1-FL02 to interface directly to EnDat
absolute encoders. EnDat absolute encoders respond on a
dedicated Clock and Data 1 MHz RS485 serial interface when their
position is requested by the controller. When you set the encoder to
the relevant encoder mode, the axis transmits an information
request to the encoder on a fixed 250
μ
s cycle.
The connections for EnDat are:

The TJ1-FL02 does not have a termination inside. In case
of long distances or disturbed communication, add an
external termination to the TJ1-FL02.
