command is responded, the response data is the data to be read.
An error code is two bytes. Byte2 is the LSB, and Byte3 is the MSB. Error codes are valid only
when the response code is 3. An error code indicates the reason why it fails to respond to
PDO1 Rx. Table 3-16 describes the definitions of the error codes.

Table 3-16 Error codes
The operation corresponding to the request code is not
allowed to be executed. The possible causes are as follows:
• The function code is applicable only on new devices and
is not implemented on this device.
• The slave station is in the faulty state when processing
this request.
For a slave device, the data address in the request of the
master station is not allowed. In particular, the combination
of the register
to-be-transmitted bytes is invalid.
The received data domain contains a value that is not
allowed. The value indicates the error of the remaining
structure in the combined request.
Note: It does not mean that the data item submitted for
storage in the register includes a value unexpected by the
program.
The parameter is set to an invalid value 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 length of the data frame transmitted by the upper
computer is incorrect, 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.
