5. Scaling of Inverter Transmitting Values
Except the parameters of the remarks, all other function codes can define the scaling relationship
of the specified function code via referring the manual’s minimum unit.
Remarks:
1) Communication data 0
－
2000 of F04.03, F21.01, F16.05, F16.08, F16.11, F16.14, F16.22 and
F16.24 corresponds to data -1000
－
+1000.
2) Communication data 0
－
200 of F16.06, F16.09, F16.12 and F16.15 corresponds to data -100
－
+100.
3) Communication data 0
－
16000 of state parameter 0x3318 corresponds to data -8000
－
+8000.
6. Protocol Function
1) Supported function
MODBUS protocol supports the below parameter operation:
Function code Instructions
0x03 To read the inverter’s function parameters and parameters in operating status
0x06
To rewrite function parameter (whether can be saved by F17.09 at power off) or control
parameter of single inverter
0x08 Circuit diagnosis
0x41
To rewrite function parameter (cannot be saved at power off) or control parameter of
single inverter
0x42 Function parameters management
0x10
To rewrite function parameter (whether can be saved by F17.09 at power off) or control
parameter of certain inverters
0x43
To rewrite function parameter (can be saved at power off) or control parameter of
certain inverters
If the operation command fails, the response is fault code. For instance, continuously read 13
function codes from F00.00 then the return frame will be as follows:
Address Parameter Error code Checksum
0x01 0x83 0x03 0x01 0x31
The fault code is the same as (function parameter
＋
0x80), and its instruction is as follows:
Exception code Instructions
0x1 Illegal function parameters.
0x2 Illegal register address.
0x3 Data fault. Data is beyond the upper/lower limit.
0x4 Slave operation fails (including fault caused by data invalid).
