General information about the system bus (CAN)
2.1
Introduction
All Lenze drive and automation systems have an integrated system bus interface to network control
components on the fieldbus level.
The system bus interface allows to exchange, for example, process data and parameter data
between the participants and to connect other modules such as decentralised terminals, keypads
and input devices as well as external controls and hosts.
The system bus interface transmits CAN objects on the basis of the CAN open communication
profile (CiA DS301, version 4.01), which was created by the
CiA
umbrella organisation (
