I use mitsubishi VFDs particularly the e700 series. They use a rs-485 serial connection. I have a python program to communicate with them. I've also toyed with a Yaskawa drive with Classicladder over modbus. These are expensive drives to buy new, but can be found on Ebay. Just other options

The spindle brake is usually something that holds the spindle after stopping. I believe my Bridgeport has a ratchet which engages a gear. Obviously, I don't want to try to use that to bring the spindle to a stop. The reason you need a braking resistor is to dissipate the back emf from the
