It looks like the huaqyang vfd. If it is then input mains to R and T. Connect motor to U, V an W and as irving says reverse any two of U, V or W if the spindle runs in the wrong direction. Braking resistor not needed. Look inside the socket on top of the spindle motor, are the connections numbered inside? If not then again check what you have done with a meter to ensure you have the three ends of the motor windings.
Before running it make sure that you have setup the parameters as stated in the manual. If I remember correctly it was very important to set these up before first running the spindle to prevent damage to it.
