6 Configuration (CAN−AUX system bus interface)
By means of a corresponding function module (e. g. CAN−I/O system bus) you can use the CAN−AUX
interface of the ECSxA axis module as an additional system bus interface.
Note!
If the function module attached to the CAN−AUX interface and the integrated system bus interface
are connected to the same system bus network, please be absolutely sure that different CAN
addresses and different identifiers have been set for the interfaces!
Tip!
Changes with regard to the CAN baud rate, the CAN addresses, and the identifiers for PDOs only
are accepted after a reset node.
A reset node can be effected by
·
Reconnection of the mains
·
Reset node command via NMT command. ( ^ 2−6)
·
Reset node via C0358 ( ^ 6−8)
6.1 CAN baud rate
In order to accomplish a communication via the system bus, all nodes have to use the same baud
rate for data transmission.
·
The configuration of the baud rate is effected via code C2451:
Code LCD Possible settings Information

C2451 CAN1 baud rate 0 0 500 kbit/s
1 250 kbit/s
2 125 kbit/s
3 50 kbit/s
4 1000 kbit/s

Save changes with C0003 = 1.
·
Changes are only valid after
reset node!
