Goodrive300 Series VFD Communication protocol
224
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:
VFD
address
Read
command
Parameters
address
Parameters
data
CRC check
01 06 00 01 00 03 98 0B
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:
VFD
address
CRC check Fault code
Abnormal
response code
01 86 04 43 A3
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:

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).
