System bus interface

The CAN connection of the system bus is physically designed according to ISO-DIS
11898 (CAN High Speed). The bus topology is the line structure.
In the default version, the ACU series of frequency inverters supports a CAN protocol
controller. This controller can be used in the CM-CAN communication module with
CANopen interface as well as in an extension module for the system bus, such as the
EM-ABS-01 extension module.

Bus termination

The bus necessary on the phase in the physically first and last subscriber can be acti-
vated via the DIP switches on the EM-ABS-01 extension module.
Set to ON (right position) for passive termination.
