4.2.2 SIO Communication Connection Using a 4-Way Junction
(Note 1) If the total length of the communication cable is 10 m or longer and you experience
communication errors, connect a terminal resistor to the last axis.
(Note 2) If the actuators use different power supplies, align 0 [V] on all power supplies.
(Note 3) The gateway unit power must be the same as 0 V of the ERC2 control power.
(Note 4) Connect the shielded wire of each axis to FG.
(Note 5) If the overall length of link cable exceeds 30 m, use wire of 22AWG or larger size.
