If you have only 3 wires, it shouldn't matter. It isn't polarized, and there isn't any Neutral wire. Just 3 hots, and an earth ground to the motor frame (safety). Be sure, of course, that your converter is set to output the correct voltage for the motor, since there are several common 3-phase voltages. If the motor has 6 or more wires coming out, you need to know which ones are the working voltage program jumpers, and which ones are the power input L1, L2, & L3 (aka T1,T2, T3). There is/was a plackard on the motor which tells which wires to hook together and jump for either 220 3-phase or 440/480 3-phase. If you get those wrong, it could damage the motor, and/or worse... My SD-10 motor has 6 wires, and each is numbered with a paper tag. There's a metal plate showing the configuration of the wires.
I'm not familiar with your phase converter, but my KB converter has several adjustments on it for start load, run load, max & min current delivery, etc.
JUST A NOTE: I was unable to get my SD-10 to start up with the KB phase converter/controller. I haven't found out why yet, but I suspect the chopper rotor is too heavy, and is tripping the over-current sensor in the converter.

Yes, that's a real 500-lb Federal SD-10 I'm holding (braggart!)
