Your ramp up and down seems pretty slow. I’m sure there are settings to change.
Can you set up a separate forward and reverse switch? Most VFDs can. I definitely would if you could. Would help in power tapping holes. Have fun! 
Edit. You should have a big/ easy to hit switch to kill the spindle. (E stop). Just in case.
