is defined as "Set frequency". To set the frequency to 50.00 Hz (that is, setting 1=0x1388), the
master station transmits the following SDO command.

Example 3: To read the running state of the VFD whose address is 3, the master station
transmits the following SDO command.

Example 4: Assume that the address of the VFD slave station is 3, and the function of setting 1
is defined as "Set frequency". To set the frequency to 50.00 Hz (that is, setting 1=0x1388), the
master station transmits the following SDO command.

3.7 Baud rate and communication address setting
3.7.1 Baud rate setting
After setting the CANopen baud rate and communication address, you need to restart the VFD
to enable the settings to take effect.
The CANopen baud rate is set through the corresponding VFD function parameter. For
