Amplifier compatible with AC Motor -Sanyo P5

I have 4 Sanyo P5 ac servo motors 200v 3-phase (750w) with incremental encoders I need amplifiers for. Probably buy from E-bay.
I believe they require a specific type of amplifier. Sinusoidal Commutation?
Copley XSL-230-36 came up in my search however is this my best bet or will others work?
I have both Mesa 5i25, 7i77 boards and Pico Universal PWM Controller boards and can use either one and I can add stuff on the end of the motor shaft if needed since these are hollow shafted.

Motor model: P50C08075HXS21
Thanks

do the motors have encoders installed?

Hi,
Yes they are installed but if something else is better no trouble putting them on the back end. Unless they are cost prohibitive.
Thanks.

Argon product.

The Argons look good however I have 5 or 6 machines I would like to convert if I can get something working good. Looking to keep costs down and not likely to find these used.

Still not expensive.
If you have several machines then the work that you do on one machine will be reproduced to the others. If you are looking for used drives, most likely you will find them all different, and that will give you more expenses at the end.
I have stock of the Argon. For price vs quantity please contact the store, that I will reply.
