Thus, for example, the voltage at the output of potentiometers 3.3 and 3.4 through the contacts 16.3.1 and 16.4.2 adjoins the first differential amplifier 9. At the output of the first differential amplifier 9 there is a differential voltage of both measurements values and memorization It is executed using the command B in the first storage device 10, made in the form of the well-known Sample & Hold-contour. The magnitude of the differential voltage is fed to the output of the absolute value generating unit 11 and, in the form of command F, to the control unit of sequence of operations 15.

    differential storage unit 10 in the first arithmetic unit 16 using an analog computational circuit consisting of potentiometers 17.1, ..., 17.4 and subsequent first operational amplifiers 18.1 to 18.4 for several actuators adjacent on both sides 1. In this In the case of the calculation of the four specified values of the four respective actuating systems, see FIG. 1. These setpoints from multiplexer 19 to the first motor control unit 21 are connected via an analog-digital converter 22 to the first comparing device 23. Through a multiplexer 19 controlled from the sequence control unit 15 by command C, there is only one motor control unit 20 refers to a variety of executive systems 1 on the input and output side.
    The first comparison device 23 is a reversible, with a memory device, a character counter 23.1. The first comparing device 23 is set up from analog-to-digital converter 22 and then the pulses of the pulse sensor by the electric motor 26 counts back to zero. At zero, a C command arises, blocking the first circuit AND 24, for further pulses of the pulse sensor of the electric motor 26 and influences the control node of the sequence of operations 15. Since the pulses from the pulse motor sensor correspond to the regulating value, the first comparison device 23 compares set value with a control value. The impulse sensor of the electric motor 26 is controlled by the command of the control unit of the sequence of operations 15, and the character memory 23.1 sets the direction of rotation.
    Controlled by the control unit of the sequence of operations with the help of co: mandand E, the output multiplexer 28 connects to the electric motors 3.1 ... 3 servo drives 2 related to the executive system 1. In the given example, the output multiplexer 28 arranges the output of the first motor control unit until the command C approaches via contacts 28.2 to 28.5 to electric motors 2.2 to 2.5.
    The principle of the remote ink supply control device with a comparison device of a predetermined value and a measured value is illustrated by the example of FIG. 2
    The contacts 34.1.1 ... A.3.4.4 of the second input multiplexer 34, the second control unit 35, controlled by the command H from the manually actuated starting node 30, connect, in accordance with command A, the measured values of several located near potentiometers 3.1, ..., З.п with the second arithmetic unit 36, as well as both average measured values by the difference forming unit 8. The second arithmetic unit 36 contains a series of uniformly constructed analog decision circuits consisting of second operational amplifiers 38.1, ..., 38.4 which are from the entrance

    By changing the first arithmetic unit 16 or the second arithmetic unit, non-linear alignments are also performed, and the number of reference points can also be increased by the corresponding distances. It is more expedient to make multiplexers in the form of analog switches with switches on field-effect transistors.

    get the specified value through the potential of the control node action of the followers 17.1, ..., 17.4 and the operations constructed by the advantage 15. It is controlled in the form of SampI & Hold-elements controlled by the command B of the storage nodes 25
    Mandu H issued by counter 42. According to this counter 42, a connected first decoder 47 issues a command A from the second output input multiplexers, so that the analog multiplexer 34. Thus, the output signal in the command F is associated with the element the limit value 56. The element of the limit value is made in the form of the well-known Schmitt trigger.
    , -, .- In the absence of exceeding the preceding differential differential voltage zero of a concurrent value, the astable pulse corresponds to the same value of a given multivibrator 45 through the second circuit And
    44 and the OR circuit 43 arrives at the counter 42 and causes a series connection there, so at the end the position sensor is polled by command A.
    If, however, the limit value is exceeded, in this case, a bistable multivibrator 48 is triggered, which forms a command H, which triggers a delay element 2Q 49, which forms a command D with delay, and through the second monostable multivibrator 53 blocks the shift register 46.
    Shift register 46 with its outputs
    , .. - serves the second decoder 54 for imaging the input and output is attached a lot of command C and, together with the counter 42, to the executive systems 1. also a third decoder 55 to form the command E. As a result,
    The zero indicator of the second comparing-the motor control unit from the positioner 41 at the differential input and output acts on the execution; the zero command issues C, which systems in the correct sequence blocks the first circuit AND 24 for further 40 telnosti. The shift register 46 is advanced by the lowest impulse of the pulse sensor with further using the command C, i.e. described by the electric motor 26 and is influenced by the ordering continues. At the output to the control unit by the sequence of the shift register 46, the final signal operation 15 occurs. A further principle, including the further counter 42, corresponds to the description of FIG. one. . scheme OR 43.
    between 39.1 and 39.4 and the second operational amplifiers 38.1, ..., 3,8.4 that are actually received, there is a differential voltage with the correct signs between the set value and the measured value, value and the measured value. It serves to align the discrete passage of the positions of the support elements of the colorful knife depending on the continuous function of the knife bending line.
    This differential voltage, via multiplexer 19, of the second control unit of the electric motor 40 is supplied to a second comparing device 41, made in the form of a zero indicator with a character storage device 23.1. By means of a multiplexer 19 controlled from the control unit of the sequence of operations 15 by means of the command C, the control unit of the electric motor 40 with
