こ利用できるものである。This invention relates to a static Leonard control system configured by combining a DC motor, and is particularly characterized in that it is equipped with a unidirectional current detector and performs reversible acceleration/deceleration without using a forward/reverse switching judgment circuit. This electric motor control method can be effectively used in fields related to fabric sheet processing such as, for example, devices for correcting the deviation of running fabric sheets, spreading devices, and sucanotures.

る。Conventionally, when operating a DC motor with IJ11 speed reduction (or reversible operation), the DC motor was connected to two SI 1-nostar converters connected in antiparallel, and the DC motor was normally connected between the two SI-17 converters. A circulating current of 10% of the rated current is set at 7 degrees, and by adjusting the current of one of the cyrisk converters, the power can be increased or decreased or reversibly operated (used).

有している。However, in the case of this method, two sets of current detectors in the forward direction and in the reverse direction, such as a forward current transformer 10, a current detection circuit 12, and a reverse current transformer [1, 2, current detection circuit J3, etc.] are used. When the speed command signal n FL and the speed detection signal are required, the forward and reverse direction current detection signals Ia F and Ia R are combined and logically determined to operate the forward or reverse direction sirisk converter 6 or 7. Since the forward/reverse switching determination circuit 14 is required for switching the forward/reverse switching, it is expensive, reduces reliability, and has major disadvantages in that there is a possibility of malfunction due to noise or the like.

The purpose of the present invention is to provide a control system υ11 that can switch and control the operation of a device.

速動作を有する制御方式となしたものである。The present invention focuses on the fact that there is a difference between the operating time of the current control system, at the start of operation and at the end of operation, and prohibits the gate pulse at the maximum gate control angle of the thyristor, and controls the switching of the forward and reverse thyristor converter. By doing so, and by performing acceleration/deceleration and reversible control of the DC motor, a control system that is inexpensive and has high-speed operation is achieved.
