Bus termination resistors (120 Ω between CANL and CANH at both ends of the bus) is essential for correct
operation of the CAN bus (mainly for long distances and high baud rates).
GND and SHIELD
The GND line in CANopen devices basically equals potentials between the master and the slaves
but is not used for data transmission as the line is fully differential.
When installing CANopen communication, ensure that each servo drive is allocated a unique ID.
Otherwise, CANopen network may hang.
