inverters Communication protocol
233
“hibernation restore delay time” is 5.0 (5.0=50
÷
10).
If MODBUS communication is used to control the hibernation restore delay time as 5.0s.
Firstly, 5.0 can be magnified by 10 times to integer 50 (32H) and then this data can be sent.
After the inverter receives the command, it will change 50 into 5 according to the fieldbus
ratio value and then set the hibernation restore delay time as 5s.
Another example, after the upper monitor sends the command of reading the parameter of
hibernation restore delay time ,if the response message of the inverter is as following:
Because the parameter data is 0032H (50) and 50 divided by 10 is 5, then the hibernation
restore delay time is 5s.
10.4.7 Fault message response
There may be fault in the communication control. For example, some parameter can only be
read. If a writing message is sent, the inverter will return a fault response message.
The fault message is from the inverter to the master, its code and meaning is as below:
Code
Name
Meaning
01H
Illegal
command
The command from master can not be executed. The reason
maybe:
1. This command is only for new version and this version can not
realize.
2. Slave is in fault state and can not execute it.
02H
Illegal data
address.
Some of the operation addresses are invalid or not allowed to
access. Especially the combination of the register and the
transmitting bytes are invalid.
03H
Illegal value
When there are invalid data in the message framed received by
slave.
Note:
This error code does not indicate the data value to write
exceed the range, but indicate the message frame is an illegal
frame.
04H
Operation
failed
The parameter setting in parameter writing is invalid. For example,
the function input terminal can not be set repeatedly.
05H
Password
error
The password written to the password check address is not same
as the password set by P7.00.
06H
Data frame
error
In the frame message sent by the upper monitor, the length of the
digital frame is incorrect or the counting of CRC check bit in RTU is
different from the lower monitor.
07H
Written not
allowed.
It only happen in write command, the reason maybe:
1. The written data exceeds the parameter range.
