If the VFD system has bypass, there will be an overload device for the bypass circuit, but if tripped, will also prevent the VFD connect to the motor. Make sure if you have a bypass function that both the VFD and bypass mode operate the motor in the same direction. Test the VFD without a motor to possibly isolate a problem (V/Hz).
