First off, 2.57 is too high. Lower ADC to2.5 volts, then check to make sure the ME Base speed is the same RPM as the Motor Nameplate, in the Drive and MSU. Then raise or lower your speed with the PPR parameters, again in MSU and the Drive. Use the motion averages screen to see when you have attained contract speed.. Also to see when the speed switches are picking. As for the going into the overhead, you may be tripping your ETS switch. Get the speeds correct then see what happens on the one floor run.
