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
Code Name Definition
00H No error /
01H Invalid command
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.
02H Invalid data address
For a slave device, the data address in the request of the
master station is not allowed. In particular, the combination
of the register address and the number of the
to-be-transmitted bytes is invalid.
03H Invalid data value
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.
04H Operation failure
The parameter is set to an invalid value in the write
operation. For example, a function input terminal cannot be
set repeatedly.
05H Password error
The password entered in the password verification address
is different from that set by the user.
06H Data frame error
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.
07H
Parameter
read-only
The parameter to be modified in the write operation of the
master station is a read-only parameter.
08H
Parameter cannot
be modified in
running
The parameter to be modified in the write operation of the
master station cannot be modified during the running of the
VFD.
