Abstract

PURPOSE:To prevent abnormal excitation by providing a data selector which switches the output of a latch circuit, supplying selected signal to a preset counter, and making the status after the switching of the excitation method continuous to the status before the switching. CONSTITUTION:The signal from a preset counter 13 is supplied to a decoder 7 through a selector 3 and a latch circuit 5. The excitation signal of a motor can be obtained from a matrix circuit 8. While, the latch circuit 5 is also connected to the second data selector 14, and its outputs are supplied to the preset input terminals of the preset counter 12. Therefore, the signals of the second data selector 14 are supplied to the preset counter 13 so that the normal excitation status can be obtained when the first command pulse is arrived after the excitation method is switched. In this procedure, the excitation statuses before and after switching are continued, and the abnormal excitation to the motor due to switching can be eliminated.
