Peter, this is the root cause in the change of behavior between <=2.6 and 2.7 w/ the 5i25+7i77 that a couple of us have been having (was discussed here about a week ago)? I have noticed an occasional warning in the prior version I was running (just at startup iirc.) I need to put some more noise filters in, but my error is from the motor contactors pulling in when I hit enable. The original dc servo drives have big contactors that disconnect the motor from the drive and put a braking resistor across it when you disable them (or hit a limit switch, etc.) Hitting the enable (F2) causes those 3 big guys to pull in and reconnect the drives to the motors. That causes the sserial glitch and trips the contactors right back off. I can't get past that step. I haven't had time this week to play w/ the inc/dec parameters like Andy Pugh suggested.
