4.1.1 SIO Communication Connection Using a Relay Terminal Block
* The emergency stop circuit is the same as illustrated on the previous page.
(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) Connect the shielded wire of each axis to FG.
(Note 4) If the overall length of link cable exceeds 30 m, use wire of 22AWG or larger size.
