8.5.3.4 Changing the baud rate and bus address (on MASTERDRIVES MC only)
It is possible to alter the baud rate and bus address using the CBC and
CANopen via manufacturer-specific objects 2100h and 2101h.
The baud rate of the CAN slave can be changed in two different ways:
♦ By using parameter P720 (see Subsection 8.5.2)
♦ By using object 2100h
Changing the baud rate with object 2100h:

Baud rate of slave on CAN bus
You can change the baud rate of the node via the bus using object
2100h. To activate the baud rate, you must first enter the value and
then execute a Reset Communication. The relevant node then
receives and sends at the new baud rate.
Parameter 60 is set to 1 by the CBC after the Reset Communication.
Parameter 720.01 contains the new baud rate stored in the EEPROM.
CAUTION: The value stored in P720.01 is not the same as the value
entered via CANopen (see table for assignment).

The node ID (bus address) of the node is set with this object. The new
node ID does not become active until the node receives a Reset
Communication command from the CANopen master.
Parameter 60 is set to 1 by the CBC after the Reset Communication.
Parameter 918 then contains the new baud rate stored in the
EEPROM.
