摘要： PURPOSE:To save the trouble of measurement and setting up of the diameter of a wound coil and to avoid the danger of the breakage of a long material at the time of starting by controlling tensile force so as to automatically attain desired tensile force then. CONSTITUTION:A divider 26 computes a torque signal T using winding diameter value which greatly decreases with the elapse of time at the beginning when a false winding diameter computing circuit 33 outputs the winding diameter value at the time of starting, and the torque of a winding out machine 3 gradually increases from its small value in accordance with the torque signal T. The tensile force of a roll paper 2 therefore also gradually increases. When the actual value of tensile force coincides with the command value of tensile force, a comparator 31 excites the first relay 32 to actuate the second relay 34, and a winding diameter signal D computed by a coil winding diameter computing circuit 24 is inputted into the divider 26 instead of the false winding diameter computing circuit 33. Thus at the time of starting, the excessive tensile force can be prevented from acting on the roll paper 2. In addition, since an adjustable computor where a deviation between the actual value and the command value of tensile force is inputted makes proportional computation at the beginning, but changes over into proportional integration computation with the action of the second relay 34, saturation can be avoided.

摘要： PURPOSE:To prevent runaway of motor through a simple constitution. CONSTITUTION:Speed detection outputs are introduced from F/V converters 2, 2A to a high signal priority detector 7 where one having higher absolute value is selected. It is then imparted with a polarity corresponding to an output from a rotational direction detector 3A fixed to motor 9 side. According to the constitution, detection of rotational direction is not required on the side of a pulse generator 1 and the F/V converter 2 and thereby the constitution is simplified, resulting in prevention of runaway of motor due to directional unmatch of the line and the motor.

摘要： PURPOSE:To prevent the output current of a power conversion device from fluctuating by preventing an AC current command value of the power conversion device which converts an AC to a DC from changing in correspondence to the fluctuation of an AC supply voltage. CONSTITUTION:When converting a DC current command value to an AC current command value using an AC supply voltage, the DC current command value is preliminarily divided by the DC voltage proportioned to an AC supply voltage and then it is converted to an AC current command value using this AC supply voltage. By this method, even if the AC supply voltage fluctuates, the effect of this fluctuation is offset and thereby the AC current command value can be stabilized. Or, with the AC supply voltage being held constant by a voltage stabilizing device, a stable AC current command value can be generated using this fixed AC supply voltage and therefore the output current of a power conversion device is prevented from fluctuating.

摘要： PURPOSE:To prevent an overspeed state even if an external force is applied to a motor by generating a torque proportional to the speed of the excess value in addition to the torque when the speed of the motor exceeds a set value at the time of feeding of a long material. CONSTITUTION:A limiting speed setter 21, a function generator 22, an amplifier 23 and an adder 24 are added to a conventional circuit. Since the setter 21 is set, for example, to the rated speed of a DC motor 4 as a limiting speed, when the feeding speed of a long material, i.e., the fact that the speed of the motor exceeds the set value due to the addition of an external force to a rewinder of feeding the material or the material is detected, a torque proportional to the difference between the set speed and the actual speed is added to the torque heretofore generated to generate it in the motor 4. Thus, it can prevent the motor 4 from becoming an overspeed state by the opposite torque resisting against the external force.

摘要： PURPOSE:To keep tension among respective wire drawing machines proper, and to prevent the trouble of the disconnection, etc., of a wire rod by controlling the line of the wire drawing machines so that the speed command values of each wire drawing machine to which a cascade control is done not reach a value higher than a rated speed command. CONSTITUTION:When the speed-change command value of either stage except a final stage reaches a rated value, relays 44, 46 are operated, and a contact RY1 or RY2 is opened. When the contact is opened, a switch circuit 47 is opened, and the speed command value of speed adjustment computing element 40 is held, thus maintaining a wire drawing machine line at a constant velicity without being accelerated faster than that. Accordingly, the wire drawing machines do not exceed rated speed even in ones, which are cascade-controlled through ratio controllers 19, 29 and motor control circuits 16, 26, 36 of which do not exceed the rated speed, and the ratio of surface reduction ratio among each wire drawing machine is kept at a fixed value and the line is operated.

摘要： PURPOSE:To prevent disconnection or dip scratches of wire material, by employing cascade control where a torque correction signal from a current balance setter retroacts on the front stage side thus performing torque control at each stage. CONSTITUTION:A torque correction signal from a current balance setter 95 arranged between stages of respective signal generators 94 serves as a corrected speed command value of self stage while simultaneously fed to a ratio setter 51 in front stage, and thereby correction at rear stage side is performed through cascade control where the front stage side is subjected to retroaction. Modification of setting in a main speed setter 53 influences over the entire stage. Since the control amount, i.e. a torque signal, is the torque of drive motors 7, 17, 27, i.e. tensile force of wire material, setting of the current balance setter 95 is adjusted to vary setting tension at each stage such that excessive tension or loosening of the wire material is not caused by external disturbance and predetermined tension is maintained automatically at each stage.

摘要： PURPOSE:To prevent hunting in stop control and to improve the stop precision of a rotating body by making the gain of a controller greater than a value before a stop when the rotating body stops. CONSTITUTION:When a main shaft 1 reaches a specific stop position and the output voltage of a magnetic sensor 10 drops to 0V, the main shaft 1 stops and a switch 17 is operated by the output signal of a comparator 16. Consequently, a voltage signal generated by dividing the output voltage of the sensor 10 through a variable resistor 18 is supplied to a thyristor Ward-Leonard device 6 through an amplifier 15. The level of the voltage signal supplied to the amplifier 15 is higher than that of a signal generated by the voltage division of a variable resistor 13 and the gain of the controller is increased after the main shaft 1 stops. Therefore, the holding force of the main shaft 1 for stopping against external force is increased. Thus, the hunting in stop control is prevented and the stop precision of the rotating body is improved.
