Example of PDO1
The VFD is a Goodrive350 series VFD, and the slave station address is 3. Assume that you
want to set the function code P15.13 of the VFD to 1.
Command analysis: The parameter address of P15.13 is 0×0F0D. According to the protocol,
the request code of PDO1 Rx is 0×02, the parameter address is 0x0F0D, and the requested
data is 0x01, and therefore PDO1 Rx transmitted by the master station is as follows.
COB-ID
0x203
If the VFD parameter is successfully modified, the following PDO1 Tx command is returned.

3.5.3 PDO2 Rx

PDO2 Rx is used to modify CWs and real-time process data (setting 1, setting 2, and setting 3)
of a VFD. A CW is used to control the start and stop of a VFD, and settings are used to control
the real-time running values of the VFD, such as set frequency.
