jkh ill check on that dynamic braking circuit. something to think about. thanks
jay, thanks for the input. i did check min pos err, it was the same as the other cars, i found a manual for the ac drive that gives a better description of all the parameters and how to adjust a car from startup. it may help. i was wondering about how to access the drive menus, there is a note on the controller saying drive password is 0000 there is a plug at bottom of drive, is this where i should access this? i was just reading the adjustment manual, and it says get to ready screen and press drive adjust button on tool, i never noticed that button before, so i will check it out. manual does say to adjust the adc1 offsets like you mention, so thanks for the insight. this is the only ac miprom i have had to deal with and have never had to access drive menu, so good learning for me. just to refresh your brain cells, measurement is 12 7/8 :}
