98 MODBUS Protocol
3. Definition of communication parameter address
Distribution of inverter parameter address:
Register implication
Functional parameter(1)
Monitoring parameter
Operation command(2)
Frequency setting
Inverter status(3)
Fault message(4)
Register address space
High is the number of function code group, while low is mark
number of function code, e.g. F1.11, the register address is F10B.
High is 0xD0 and low is monitoring mark number, e.g. d-12, the
register address is D00C
0x1001
0x1002
0x2000
0x2001
Note:
(1)The frequent writing of function code parameters in the EEPROM will reduce
its service life. Some parameters in the communication mode don’t need to store,
but to modify the RAM value. When writing the functional parameter of RAM,
just change “F” to “0” in the high address of the register, e.g. when writing the
RAM value of F1.11, its register address should be 010 B, but the expression
method of the register address cannot be used to read the functional parameters
of the frequency inverter.
(2) Operation command corresponding to operation command code:
Operation command code
0x0000
Operation command
Invalid command
0x0001
FWD running start
0x0002
0x0003
0x0004
0x0005
0x0006
0x0020
REV running start
Stop
FWD inching of slave machine
REV inching of slave machine
Inching running stops
Fault reset of slave machine
(3) Inverter status:
Inverter status code
0x0000
0x0001
0x0002
0x0003
0x0004
0x0005
Indication
