Termination None
Connection example
The example shows the connections for the TJ1-FL02 to a F7 Inverter for
position control.
The encoder from the motor must be connected to the encoder interface
(PG-X2) in the Inverter (connector TA1). The encoder signal is forwarded in
the connector TA2 of the (PG-X2).
Make the connections for the 18 pin connector on the TJ1-FL02 to the
terminal board on the F7 Inverter as follows:
