I am about to order an electronic AC variable speed drive for my lathe. I am planning on installing the drive in a metal enclosure similar to a electrical circuit breaker box. Reading through the online manuals for the drive I am looking at, it appears that they are sensitive to both heat and dust. A couple of questions for you guys:
1) Did you use an enclosure for your VSD?
2) How much clearance did you provide between the VSD and the interior of the box (sides and top)?
3) Did you install a cooling fan in the enclosure?
4) Did you provide ventilation holes in the enclosure, and if so, what did you do to prevent dust from entering enclosure?
5) Any other issues?
Your thoughts and comments are truly appreciated.
