Goodrive300 Series VFD
For example, set the "running command channel" of the VFD (P00.01, parameter address is 0001H)
with the address of 01H to 03, the command is as following:
01
VFD
address
But the setting range of "running command channel" is 0–2, if it is set to 3, because the number is
beyond the range, the VFD will return fault response message as below:
Abnormal response code 86H means the abnormal response to writing command 06H; the fault code
is 04H. In the table above, its name is operation failed and its meaning is that the parameter setting in
parameter writing is invalid. For example, the function input terminal cannot be set repeatedly.
10.4.8 Example of writing and reading
Refer to 10.4.1 and 10.4.2 for the command format.
10.4.8.1 Example of reading command 03H
Read the state word 1 of the VFD with the address of 01H (refer to table 1). From the table 1, the
parameter address of the state word 1 of the VFD is 2100H.
The command sent to the VFD:
01
VFD
address
If the response message is as below:
01
VFD
address
The data content is 0003H. From the table 1, the VFD stops.
Watch "the current fault type" to "the previous 5 times fault type" of the VFD 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 VFD:
