Thanks, Al. The unit runs pretty much nonstop, 24/7. No way to use a small DC computer fan? The reason I ask is because I see a +10V output terminal on the VFD.

Al has it right again. The +10 feeds the speed pot and provides for your stop-for-rev circuit. We used the enclosure that housed the for-rev contactors, I'm guessing 16 x 16 x 10. We used braking resitors to eat up emf and slow the motor down quickly. we have not had any problems with heat. It has been fairly trouble free.
