Abstract

PURPOSE:To shorten the driving time of pulse motor by providing a counter to count the number of pulse supplied to a pulse control circuit and pulse motor and an arithmetic memory to read the content of the counter every a certain period and to compute and memorize the integrated value of the number of pulse. CONSTITUTION:The pulse control circuit consisting of the pulse generation equipment 10, the divider 50, the flip-flop group 90, etc., controls the pulse signal 19 and the directional control signal 29 supplied to the pulse motor 30. The pulse signal 19 is counted at the counter 130, is read in the computer 140 with the directional cotrol signal 29 through the gate group 135 by the reading signal 69 put out every a certain period from the arithmetic memory 100. At this point, by using the difference between this discrete value and the value previously read, the integrated value of the supplied pulse is calculated. The holder 145 and the decorder 150 in the arithmetic memory 100 selectively sets and resets the flip-flop group 90 when the input-output address is selected by the memory program in the counter 140.
