parameter setting in parameter writing is invalid. For example, the function input terminal can
not be set repeatedly.
10.4.7 Example of writing and reading
Refer to 10.4.1 and 10.4.2 for the command format.
10.4.7.1 Example of reading command 03H
Read the state word 1 of the inverter with the address of 01H (refer to table 1). From the
table 1, the parameter address of the state word 1 of the inverter is 2100H.
The command sent to the inverter:
If the response message is as below:
The data content is 0003H. From the table 1, the inverter stops.
Watch “the current fault type” to “the previous 5 times fault type” of the inverter through
commands, the corresponding function code is P07.27~P07.32 and corresponding
parameter address is 071BH~0720H(there are 6 from 071BH).
The command sent to the inverter:
If the response message is as below:
See from the returned data, all fault types are 0023H (decimal 35) with the meaning of
maladjustment (STo).
10.4.7.2 Example of writing command 06H
Make the inverter with the address of 03H to run forward. See table 1, the address of
“communication control command” is 2000H and forward running is 0001. See the table
