CAN-bus connection (for CAN drives only)

3.4.9.1

CAN connection

Remarks:
1. The CAN network
Figure 3.25 shows how to connect it on your network
2. CAN signals are not insulated from other iPOS80x0 circuits.
3.4.9.2

Recommendation for wiring

a) Build CAN network using cables with twisted wires (2 wires/pair), with CAN-Hi twisted together with CAN-Lo.
It is recommended but not mandatory to use a shielded cable. If so, connect the shield to GND. The cable
impedance must be 105 ... 135 ohms (120 ohms typical) and a capacitance below 30pF/meter.
b) The 120Ω termination resistors must be rated at 0.2W minimum. Do not use winded resistors, which are
inductive.
