by the baud rate.
CAN communication is offline
or the error receiving counter
exceeds 128.
CAN communication is offline

exceeds 128.
In the case where a slave
node is configured
generate synchronization
signals,
synchronization signals are
received.
In asynchronous
mode, the number of frames
received by a slave node
exceeds the range supported
by the baud rate.
The SDO attempts to modify
parameters in a state that
disallows modification.

to Modify configuration so that there is
only one
external generation source in the entire
communication network.
working 1. Modify the time interval for the
master node to send data frames.
2. Modify the mode for the slave
node to send TPDOs.
3. Change the baud rate.
Adjust the CANopen status machine
to the Pre-OP or OP state and then
try to modify parameters.
