Filed: 1996-03-19
Abstract: PROBLEM TO BE SOLVED: To facilitate step motor control by obtaining a pulse output of a frequency, proportional to frequency setting dada with a simple configuration and to reduce number of components. SOLUTION: An adder 2 sums stored circuit output data storing output data of an N-bit adder 2 and pulse frequency setting data D, and an N-bit latch circuit 3 hold an output of the adder for each clock period at a leading edge of a basic clock pulse. The latch circuit 3 provides an output of a most significant bit of latched data for each clock. When the hold data exceeds 2N<-1> , a carry is produced and the N-bit holding circuit 3 outputs an output pulse with a period of carry period (multiple of 2N/D of a clock period). Since the frequency of the output pulse is a multiple of D/2N of a clock frequency, the frequency is proportional to the frequency setting data D.

Title: Detection for abnormality of digital control system
Inventor: TASAKA YASUO
IPC: G05B23/02
Filed: 1984-05-09
Abstract: PURPOSE:To find the abnormality in the early stage by judging input data to be abnormal if the difference between preceding input data and current input data of a digital control system exceeds a set value. CONSTITUTION:When a switch S1 is closed to take in data, a comparing circuit 2 compares preceding data in memory 1 with current data; and if the difference is within the set value, a switch S3 is closed to input current data to a PID arithmetic circuit 3. The switch S3 is opened, and the switch S2 is closed, and current data is stored in the memory 1 to prepare for the next sampling. If said difference exceeds the set value, data is not to the PID arithmetic circuit 3 by interlocking. Thus, the abnormality of input data is found in the early stage, and the abnormal control based on abnormal data is prevented.
