4 Configuration (AIF interface)
By means of an according fieldbus module (e. g. 2175) you can use the AIF interface of the 9300
Servo PLC, drive PLC and of the ECSxA axis module as an additional system bus interface.
Note!
If the fieldbus module attached to the AIF interface and the integrated system bus interface are
connected to the same system bus network, please be absolutely sure that different CAN
addresses as well as 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 ( ^ 3−8)
4.1 CAN baud rate
In order to accomplish 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 C2351:
Code LCD Possible settings Information
Lenze Selection
C2351 XCAN baud rate 0 0 500 kbit/s
1 250 kbit/s
2 125 kbit/s
3 50 kbit/s
4 1000 kbit/s
5 20 kbit/s (not for ECSxA!)
6 10 kbit/s (not for ECSxA!)

Save changes with C0003 = 1.

Changes are only valid after
reset node!
