(4) Linking ERC2-NP/PN controllers via SIO communication
Use relay terminal blocks to link the controllers as shown below.
Caution
(1) If the total communication cable length is 10 m or longer and a communication error occurs
because of difficulty establishing successful communication, connect a terminal resistor to the last
axis.
(2) If each actuator uses a separate power supply, use a same ground 0 [V].
(3) The power supply of the Gateway Unit and the control power supply of each ERC2 controller
must share a common ground 0 V.
(4) Connect the shield line to the FG terminal for each axis.
(5) If the total link cable length exceeds 30 m, use a cable with a wire size of AWG22 or greater.
