Re: Victors not synchronized - dual motor train

A simple way to get everything calibrated is to remove all the breakers but the one you want to calibrate. Go through the calibration procedure. (remember the values are not stored until you release the button.) Then swap breakers and repeat until all the controllers are calibrated. It is not unusual to have a little "chatter" at dead stick but if you think it is a problem, increase the deadband and see if that fixes it. When you have two different motor types running in the same transmission, you are likely to get noises that are combinations of the two that you never heard before. Just be sure that each motor is adding to the overall output, that no motor is drawing more than expected currents and that all motors are running in the same direction for the same input. (removing breakers helps on this test as well.)
