PfofiBus Gateway
(3) SIO communication connection for ERC2-SE
For details, refer to the ERC2-SE operation manual.
Use 4-way junctions to connect the cables as shown below.
The power-supply & I/O cable and network connection cable (including the 4-way junction and e-
CON connector) are standard accessories of the ERC2-SE.
Caution
(1) When the total communication cable length is 10 m or longer, communication may not be
established properly and a communication error may occur. In this case, connect a terminal
resistor to the last axis.
(2) If the actuators have different power supplies, use a common line for 0 [V].
(3) Use a common line for 0 [V] for the power supply of the gateway unit and control power supply of
the ERC2.
(4) Connect the shield wire to the FG for each axis.
(5) If the total link cable length exceeds 30 m, use wires with a size of 22AWG or larger.
