Not a huge amount of info for that motor on Parkers site, what there is seems a bit contradictory.
Regarding the Kw, you work it out from the Continuous Torque and the rated speed. Strange thing is looking at the part number it seems to suggest rpm is 5200 but working backwards from the torque and Kw suggest it is approx 3300rpm, maybe the part number is giving the speed at 480v or something.
I did see mention of the aries series being ok for that motor but as I said the next thing I read seemed to contradict it, so not sure.
Maybe see if you can find the programming software, often you can set up an offline drive in the software and it will give you a list of compatible motors.
One last thing, according to the part number it seems to have a single turn Hiperface encoder, if that is correct then you will have to make sure any drive you get has that capability as they are sine/cosine encoders.
