Leonardo, I recently had a problem very similar to this with my Kira machining center. The light combination indicated a low voltage problem and when checked every way I knew how, it wasn't there. So I suspected the drive and sent it away for an expensive repair and got perilously close to some critical deadlines waiting for its return. The repair company (Galco) didn't find anything wrong but replaced the caps and other miscellaneous small parts and sent it back. I still had the faulting at intermittent times and was back to square one.
Then it hit me like a ton of bricks - I had recently replaced an air compressor and I could trace the faults, when they did occur, to a voltage drop when the compressor kicked in. So I decided I should either get a soft-starter or a VFD for the compressor. I ended up sourcing a Schneider soft-start from Newark at about $230, and it took a phone call to schneider to find out what the documentation lacked but it was an easy wiring job and there are no more Kira problems. I realize this may have nothing to do with your problem except perhaps to alert you to think about anything that may be contributing to your issue. In my case, my Kira was doing exactly what it was supposed to do - fault if that voltage went low.
