power off
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.
01
VFD
address
After the VFD 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 VFD is as following:
01
VFD
address
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 VFD will return a fault response message.
The fault message is from the VFD to the master, its code and meaning is as below:

command
data
The command from master cannot be executed. The reason
maybe:
1. This command is only for new device;
2. Slave is in fault state and cannot execute it.
Some of the operation addresses are invalid or not allowed to
access. Especially the combination of the register and the
