In electric motor belt driven machines using DC motor logic control, the algorithm allows for only a small variation in friction. The algorithm determines the proper acceleration rates. If the friction varies too much, the control algorithm will not be able to compensate and erroneous acceleration rates will result in hard escapement failures: drifting margins, escapement, piling, etc.
