Goodrive350-UL Series VFD Communication protocol
-281-
But the setting range of the "Running command channel" is 0 to 2. The value 3 exceeds the setting
range. In this case, the VFD returns an error message response as shown in the following:
VFD
address
CRC Error code
Exception
response code
01 86 04 43 A3
The exception response code 86H (generated based on the MSB "1" of the write command 06H)
indicates that it is an exception response to the write command (06H). The error code is 04H. From
the preceding table, we can see that it indicates the error "Operation failure", which means "The
parameter is set to an invalid value in the write operation".
9.4.8 Read/Write operation example
For the formats of the read and write commands, see Sections 9.4.1 and 9.4.2.
9.4.8.1 Read command 03H examples
Example 1: Read state word 1 of the VFD whose address is 01H. From the table of other function
parameters, we can see that the parameter address of state word 1 of the VFD is 2100H.
The read command transmitted to the VFD is as follows:
Read
command
VFD
address
CRC
Parameter
address
Data quantity
01 03 21 00 00 01 8E 36
Assume that the following response is returned:
Read
command
Number
of bytes
Data content
CRC
VFD
address
01 03 02 00 03 F8 45
The data content returned by the VFD is 0003H, which indicates that the VFD is in the stopped state.
Example 2: View information about the VFD whose address is 03H, including "Type of current fault"
(P07.27) to "Type of last but four fault" (P07.32) of which the parameter addresses are 071BH to
0720H (contiguous 6 parameter addresses starting from 071BH).
The command transmitted to the VFD is as follows:
VFD
address
Read
command
Start
address
6 parameters in total CRC
03 03 07 1B 00 06 B5 59
Assume that the following response is returned:
VFD
address
Read
command
Number of
bytes
Type of
last fault
Type of
current fault
Type of last
but one fault
CRC Type of last
but two fault
Type of last
but three fault
Type of last
but four fault
03 03 0C 00 23 00 23 00 23 00 23 00 23 00 23 5F D2
From the returned data, we can see that all the fault types are 0023H, that is, 35 in the decimal form,
