4 System bus (CAN) / CANopen
The control technology based on CANopen allows for the integration of all Lenze device series
provided with the Lenze system bus (CAN on board).
In order to extend the existing limits of the CAN bus, several CAN lines synchronised with each other
can be used. The number of CAN lines available depends on the equipment of the Lenze Controller
in each case.
The maximum possible number of nodes on a CAN line depends on the baud rate and the cycle time
set.
Example: In the case of a cycle time of 1 ms and a baud rate of 1 Mbps, three nodes with a setpoint
PDO and an actual value PDO, respectively, can be actuated on the CAN bus.
