    I had an unusual event this week. We have several dead Rockwell VFDs on our shelf at the shop. Over the years this has been an ongoing problem with the maintenance we do. I switched to TB Woods a few years back (1991) because I could swap parts from one drive to another. Then my source for TB Woods drives convinced me to switch to Yaskawa (2001). We have been using the Yaskawa ever since. Lately we use the A-1000 drives for almost everything. But I also use another and I love those guys at Automation Direct, especially Dean. The tech support from those guys is unmatched by anyone, even Yaskawa. So I have as many Automation Direct drives out there as Yaskawa. I know I can get a drive the next day with them. Nobody else can do that!

    Honestly, neither has failed until this week, we had one with an unusual CF3 fault. One day we would have it, the next day not. I decided to replace it. It was nearly 3 years old anyway. But what causes a drive like that to fail occasionally? CF3 fault means the power source is not even. But there was a 3 other drives in the same cabinet and they work great. I did a lot of wire checking and re-terminating. Took it apart looking for circuit board cracks. NOTHING

    So it is at my office now. It was working when I removed it. “Bloody Ell” as Doug Mellor used to say. Anyone have similar experiences with drives? You can start working on them and 4 hours later you say “where am I?”
