①
1 = Parameter cannot be modified because password protection is turned on.
②
2 = Slave cannot recognize the requested function instruction. That is
(
not 3, 5, 6
)
.
③
3 = CRC check error.
④
4 = Slave does not contain the requested word address.
⑤
5 = This parameter is invalid and out of range.
⑥
6 = Parameter is read-only and cannot be modified.
⑦
7 = The system locks this parameter.
3.4 Communication mapping register address distribution
Frequency inverter parameter register set and function code one-to-one correspondence.
Read and write
frequency inverter parameter registers via Modbus communication the contents in the can realize the read-write
operation of the corresponding function code. The read-write characteristics and scope of the function codes follow
the definition of the function parameters of the frequency inverter. The address of the frequency inverter parameter
register consists of a high byte and a low byte. The high byte code function code group number and the low byte
represent the function code serial number in the corresponding function code group. The corresponding relationship
is shown in the following table:

Note: frequent write operations can damage internal memory!
①
Execute the write command, and the data will be written into the internal register. The memory has a limit on
the number of write operations. If the limit is exceeded, the memory address will be destroyed. Please avoid frequent
write operations.
②
If it is necessary to write to an address frequently, it is recommended to use the function instruction 0x05 or
the address of the write ram operation.
Communication control frequency / torque special register address 1000 h (readable / writable)
When frequency source F0 - 03 = 9, the setting frequency of the frequency inverter can be modified by writing
data to this address. Scope of data - 10,000 - 10,000, corresponding to a given value of - 100.00 % - 100.00 %.
The communication reads the 1000 h register value, and the response data word is the communication setting
value.
