Rules
When using CAN communication, connect the CGND terminal of the host controller
device to the CGND terminal of the servo driver, as shown in the following figure.
Figure 3‑10 Correct CAN connection way
● A CAN communication terminal resistor is embedded in the PLC and therefore the
corresponding DIP switch must be set to ON.
● It is recommended to ground the shield at single end.
● Do not connect the CGND terminal of the host controller to the GND terminal of
the servo drive. Otherwise, the servo drive may be damaged.
