Hardware reference
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 μs cycle.
The connections for EnDat are:
/i
Encoder signal Axis A
DATA 6
/DATA 7
CLOCK 1
/CLOCK 2
GND 5 / 15
Note
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.
The table below and the figure give an example of how to connect the
Heidenhain ROC 425 2048 5XS08-C4 encoder to the TJ1-FL02.
