Example of PDO1

The VFD 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 PDO2 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.
Request code
COB-ID
Byte0
0x203 0x02
If the VFD parameter is successfully modified, the following PDO2Tx command is
returned.
Response code

0x183 0x01
7.2.3.3 PDO2 Rx
PDO2 Rx is used to modify CWs and real-time process data (setting 1, setting 2, and
202403 (V1.0）
Note: It does not mean that the data item submitted for
storage in the register includes a value unexpected by the
program.
The parameter setting is invalid in the write operation. For
example, a function input terminal cannot be set repeatedly.
The password entered in the password verification address is
different from that set by the user.
The data frame sent from the host controller is incorrect in the
length, or in the RTU format, the value of the CRC check bit is
inconsistent with the CRC value calculated by the lower
computer.
The parameter to be modified in the write operation of the
master station is a read-only parameter.
The parameter to be modified in the write operation of the
master station cannot be modified during the running of the
VFD.
If the master station does not provide the correct password to
unlock the system to perform a read or write operation, the
error of "system being locked" is reported.
