After receiving the command, the inverter converts 50 into 5.0 based on the fieldbus scale, and then
sets "Wake-up-from-sleep delay" to 5.0s.
For another example, after the upper computer transmits the "Wake-up-from-sleep delay" parameter
read command, the master receives the following response from the inverter:

data

The parameter data is 0032H, that is, 50, so 5.0 is obtained based on the fieldbus scale (50/10=5.0).
In this case, the master identifies that the "Wake-up-from-sleep delay" is 5.0s.
9.4.7 Error message response
Operation errors may occur in communication-based control. For example, some parameters can
only be read, but a write command is transmitted. In this case, the inverter returns an error message
response.
Error message responses are transmitted by the inverter to the master. The following table describes
the codes and definitions of the error message responses.
Code
Name
Definition
01H
Invalid
command
The command code received by the upper computer 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 is in the faulty state when processing this request.
02H
Invalid data
address
For the inverter, the data address in the request of the upper
computer 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 bit
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
The password entered in the password verification address is
