Servo Motor Speed Control

Folks, I would like to use the following servo/driver as my main motor:

https://www.omc-stepperonline.com/dsy-series-200w-rs485-dc-servo-motor-24-70vdc-0-637nm-3000rpm-17-bit-incremental-encoder-ip65-dsy-rs200l2a2-m17s

I only need speed control. No other servo features/functions are needed.

How can I accomplish this? Is there anything off the shelf for this? Is this the correct subreddit to ask this?
