INVT Goodrive3000 GD3000-01-055G-12 Operation Manual page 215

Goodrive3000 series medium voltage inverters
04H. In the table above, its name is operation failed and its meaning is that the parameter setting in
parameter writing is invalid.
8.4.7 Example of writing and reading
Refer to 8.4.1 and 8.4.2 for the command format.
8.4.7.1 Example of reading command 03H
Example 1: 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.
Example 2: 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).
8.4.7.2 Example of writing command 06H
Example 1: Make the inverter with the address of 03H to run forward. See Parameter list of other function
codes, the address of "communication control command" is 2000H and forward running is 0001. See the
table below.
