We had about 10" of snow on the ground before the short melt hit, making things a bit soggy. Then the temps dropped again and we got another 3 - 4 inches over the last couple of days. Hopefully, they'll have the roads cleared by the time I set out. Mark On 01/11/2016 08:14 AM, Peter Blodow

Mark, it surely was interesting, when I drove to Traverse City last time, some 50 years ago, when I was temporarily a Michigander. Was a nice skiing weekend. Peter Am 11.01.2016 13:34, schrieb Mark: > 8 Degrees and snowing here in Grayling, MI this morning. I have to > drive over to Traverse

Well none of the suggestions about star grounding did any good. In fact they made the problem worse than before, so bad I could not even get 2.6 to run. Off this list I was sent the AB servo best wiring practices pdf which explained how to reduce noise in a servo drive enclosure. I followed

Do you have filters just prior to the input power on the AB Servo drives? I've also had problems with Teco servo drives backfeeding noise into the AC line and messing with Mesa boards. An input filter from AD fixed that problem as well. Dave On 1/10/2016 6:44 AM, John Thornton wrote: > Well

I tried to find the original message in previous monster thread to have a better understanding of the problem but could not find it. I can't remember seeing what is connecting to VFD and few other things. I assume it's a Mesa board but which one? [1] We all seem to keep running in circles

I understand.I'm working out of town and just came back for the weekend. For me this is a good time to be distracted with too much work. It helps me ignore the wind gusts to 30 mph, the snow, and the temps headed to 8 degrees F for tonight. Except that I need to drive a long ways in this
