  • Patent number: 4156105
    Abstract: A circuit arrangement is disclosed which compares a preferred position of a type carrier driven by a stepping motor with binary values of signals actuating the stepping motor. If a signal assigned to the preferred position and a signal produced by the binary values of the signals do not coincide, stepping pulse trains are fed to the stepping motor until coincidence is reached. The stepping motor is thereby accelerated in accordance with an acceleration program so that said stepping motor runs with an approximately constant load angle as soon as possible, and that an unequivocal assignment exists between the stepping pulses and the position of the type carrier.
