P720 (CB parameter 10)
Baud rate of slave on CAN bus
This parameter sets the baud rate of the slave on the CAN bus according to
the following table:
If the baud rate is outside the valid range, error F080 is displayed when the
system exits state 4 "Board configuration". Once you have acknowledged the
error, the system returns to the "Board configuration" state where you can
correct the faulty parameter assignment.
Internal defaults for bus timing as a function of baud rate:

Special CAN bus settings
•
Index i001:
This parameter can be set to switch between CAN layers 2=0
and 7=1 (CANopen).
P918.1 (CBC bus address)
The node address of the device on the CAN bus is set in this parameter.
The default setting is 3, thereby providing the MASTERDRIVES with a valid
bus address. It can be addressed directly under node ID 3.
After the basic parameters have been set as specified in the flowchart
at the beginning of this section, other parameters can be set via the
CAN bus.
