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.
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
0x08 Circuit diagnosis
0x41 To rewrite function parameter or control parameter of single inverter.
0x42 Function parameters management
0x43 To rewrite function parameter or control parameter of certain inverters.
If the operation command fails, the response is fault code. For instance, continuously read 5
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).
0x16
Unsupported operation (unsupported to read the attributes, factory default and
upper/lower limit for the control parameter and status parameter).
0x17 The register number of command frame is fault.
0x18
Incorrect information frame, including incorrect information length and incorrect
checking.
0x20 Parameters cannot be modified.
