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 data returned is available to BASIC and you
can use it to drive a servo motor.
In the figure, A is the encoder side, and B is the receiving side.
The connections for Tamagawa are:

GND 5 / 15
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 Tamagawa TS5667N420 encoder to the TJ1-FL02.
