Goodrive350 IP55 High-ingress Protection Series VFD
Assume that the following response is returned:
01
VFD
address
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 present
fault" (P07.27) to "Type of 5th-last 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:
03
VFD
address
Assume that the following response is returned:
03 03 0C 00 23 00 23 00 23 00 23
VFD Read Number of
address command
bytes
According to the returned data, all the fault types are 0023H, that is, 35 in the decimal form,
which means the STo fault.
9.4.7.2 Example of writing command 06H
Example 1: Set the VFD whose address is 03H to run forward. According to the table of
address description of other function codes in section 9.4.4.2 Addresses of other Modbus
functions, the parameter address of "communication-based control command" is 2000H and
forward running is 0001H. See the following figure.
