3.8.3 Wiring Examples for Linking Multiple Axes
 Using only a SIO converter
(The same wiring applies to a configuration for automatic operation via serial communication.)
(Note 1) If a communication error occurs when the overall length of communication cable is 10 m or
more, connect a SIO converter 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.
