If there is one figure behind the radix point in the setting range or the default value, then the
fieldbus ratio value is 10. if the data received by the upper monitor is 50, then the
"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.
9.4.7 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
Illegal
01H
command
Illegal data
02H
address.
03H Illegal value
04H Operation
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.
Some of the operation addresses are invalid or not allowed to
access. Especially the combination of the register and the
transmitting bytes are invalid.
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.
The parameter setting in parameter writing is invalid. For example,
