VFD is controlled through programmable low voltage inputs, it is not designed to be a 3 phase source other than a direct connect to the motor. If you want 3 phase power to work with the stock controls, most people go with an RPC. The programmable inputs operate the run commands for forward-reverse-stop depending on how they are connected. In addition you might want a jog either forward or reverse, and different braking rates, there are a number of options.
On the run command, there is 2 wire control and 3 wire control, so 2 or 3 inputs are used. Doesn't leave much if you want other VFD functions. Running the VFD from the VFD controls directly is cumbersome and dangerous. Example below are the assigned inputs for a different VFD, the Galt does not offer this type of 3 wire control.
