Hi all,

Anybody else here running a VFD spindle on their IH mill? If so, what kind of spindle control board are you using? My mill is an older IH with a VFD and belt drive. It was built by Aaron Moss back before he sold the company to Gene and Tommy. The VFD is controlled by a Sound Logic Spindle Control board. For a while now the board has had issues. Occasionally the spindle would not come on when commanded. I've always been able to get the spindle turning by "wiggling" the 0-10v wires from the board to the VFD (I know, but it worked). But now, the spindle board is completely dead and not putting out any voltage even when I perform the very scientific "wiggle" procedure. Its time to replace it. In looking online for a replacement I see that board is no longer available. I'd like to know what others are using and what board IH currently uses in their turnkey mills.

thanks
