Delta AS228P-A User Manual

10.2.4.2 The CAN Network Endpoint and the Topology Structure
In order to make the CAN communication more stable, the two endpoints of the CAN network are connected
to 120 ohm terminal resistors. The topology structure of the CAN network appears below.
10.2.4.3 The Topology Structure of the CANopen Network
1) Use standard Delta cables when wiring the CANopen network. These cables are the thick cable UC-
DN01Z-01A, the thin cable UC-DN01Z-02A, and the thin cable UC-DN01Z-02A. Separate the
communication cables from any power cables to avoid interference.
2) Connect the CAN+ (white) and CAN- (blue), which are at the endpoints of the network, to 120 ohm
resistors. The AS-FCOPM card is equipped with a 120 ohm resistor switch; you can enable the resistor
with the switch. Purchase the standard Delta terminal resistor for use with the other devices and the RJ45
connecter.
3) Note the limitation on the length of the CANopen network. The transmission distance of the CANopen
network depends on the transmission rate of the CANopen network. The following table shows the
relation between the transmission rate and the maximum communication distance.
Transmission rate
(bit/seconds)
