GD350A series high-performance multifunction VFD
-299-
Assume that the following response is returned:
VFD
address

command
Number of
bytes
Last fault
type
Present
fault type
2nd-last fault

5F D2
According to the returned data, all the fault types are 0023H, that is, 35 in the decimal form, which
means the maladjustment fault (STo)
9.4.8.2 Examples of write command 06H
Example 1: Set the VFD whose address is 03H to be forward running. Refer to the table of other
function parameters, the address of "Communication-based control command" is 2000H, and 0001H
indicates forward running.
