JBD,
Good point regarding other equipment failure resulting from lightning. If other equipment did not see catastrophic failure I doubt that it was lightning.
I once had several inverters that had defective input bridges when we received them. Of course they did not fail until the drives had run for several days or weeks. The warranty covered the repairs.
Not to knock Allen Bradley, but my drive repair guy hates the control. Just the drives, not the PLC's ect....
