2 General information on the system bus (CAN)
2.1 Introduction
All Lenze drive and automation systems are provided with an integrated system bus interface for the
networking of control components on a field level.
Via the system bus interface, among other things process data and parameter data can be
exchanged between the nodes. Furthermore the interface enables the connection of further
modules, like for example decentralised terminals, operator and input devices, as well as external
controls and host systems.
The system bus interface transfers CAN objects following the CANopen communication profile
(CiA DS301, version 4.01), which was developed under the umbrella association of the CiA (CAN in
Automation), complying with the CAL (CAN Application Layer).
