9.6.4 Communication Data Address Definition
This part is the content of the communication, used to control the operation of the inverter, inverter
status and related parameters setting.
Read and write functional code parameter (some function code which can not be changed, only for
the use of manufacturers or monitoring) :
Function code parameter address label rules:
By function block number and the label for the parameter address said rules:
High byte: F0 ~ FF (group F), A0 - AF (group A), 70-7 F (U) low byte: 00 to FF
Such as: F3-12, address represented as F30C;
Note:
FP groups: neither read the parameters, and do not change the parameters;
U group: only can read, do not change the parameters.
When some parameters in converter is in operation, do not change;Some parameters of the
frequency converter in any state, cannot be changed;Change function code parameters, but also pay
attention to the range of parameters, units, and related instructions.
In addition, frequent block because the EEPROM is stored, the service life of the block can reduce
the EEPROM, so some function code under the mode of communication, do not need to store, just
change the value of RAM.
If to F group of parameters, in order to realize the function, as long as this function code address high
F into 0 can be achieved.
If for A group of parameters, in order to realize the function, the function code as long as the address
of A high into 4 can be achieved.
Corresponding function code shown by the following address:
High byte: 00 ~ 0 F (group F), 40 ~ 4 F (group A), 50 ~ 5 F (group b)
Low byte: 00 to FF
Such as:
Function code F3-12 in the block is not stored in the EEPROM, address for 030 c;
Function code block A0-05 is not stored in the EEPROM, address represented by 4005;
The address said can only do write RAM, do read, read, as invalid address.
For all the parameters, can also use the command code 7 h to implement this feature.
