AN BUS COMMUNICATIONS
i
For additional information on CAN Bus and CAN hardware, refer to the
Standard ISO 11898. The AC SuperDrive conforms to the CANopen software
protocol
The AC SuperDrive employs an isolated CAN bus interface. Figure 18 illustrates the wiring
configuration for:
•
AC SuperDrive on a CAN network.
•
VMC20
The CAN Bus must be wired in a “Daisy chain” arrangement as shown in Figure 18. Twisted pair
wiring is required for the CAN_H and CAN_L signals. Both physical ends of the CAN Bus must
be terminated with 120 ohm resistances. A service device connector in a safe, convenient
location should be included in the wiring configuration. Additionally, CAN Bus wiring should be
physically separated from conductors carrying high currents.
The CAN bus is often opto-isolated to get sufficient noise margins in units that are switching high
currents (such as ACS). In these units, CAN GND is a reference point for the CAN
communication (CAN H and CAN L). CAN GND should be connected to B- at one point, and
preferably one point only. If all units on the CAN bus are isolated, CAN GND should be externally
connected to B- (see Figure 18).
