Description

전류지령 회로의 고장 검출 및 옵-셋 자동 조절방법 및 회로Fault detection and offset auto-adjustment method and circuit of current command circuit

본 내용은 요부공개 건이므로 전문내용을 수록하지 않았음Since this is an open matter, no full text was included.

제2도는 본 발명에 따른 전류 지령회로의 고장 검출 및 옵셋 자동조절 회로,2 is a fault detection and offset automatic control circuit of the current command circuit according to the present invention,

제3도는 본 발명에 따른 동작 플로우챠트도.3 is a flowchart of an operation according to the present invention.

Claims (2)

전류 지령회로의 D/A콘버터(3)의 출력 전류지령간(I)을 다시 A/D콘버터(4)의 입력으로 받아들여 디지탈화하여 이값과 D/A콘버터(3)의 입력 디지탈 값과 비교하여 그 차이 정도에 따라 출력전류 지령값(I)의 옵-셋을 조설해주고, 그 차이 정도가 심하면 전류 지령회로의 고장을 검출하게하는 것을 특징으로 하는 전류지령회로의 고장검출 및 옵-셋 자동 조절방법.The output current command (I) of the D / A converter (3) of the current command circuit is again inputted to the input of the A / D converter (4) and digitalized to compare this value with the input digital value of the D / A converter (3). To offset the output current command value (I) according to the degree of the difference, and if the difference is severe, to detect the failure of the current command circuit. How to adjust. CPU(1)의 지령에 따른 롬(2)의 데이타값을 D/A콘버터(3)에서 아날로그 값으로 변환시켜 전류지령값(I)을 출력하는 전류지령 회로에 있어서, 상기 D/A콘버터(3)로부터의 전류 지령값(I)을 입력받아 디지탈같으로 변환시켜 D/A콘버터(3)의 입력 디지탈값과 비교되게하는 A/D 콘버터(4)를 포함하여 구성되는 것을 특징으로 하는 전류 지령회로의 고장검출 및 옵-셋 자동조절 회로.In the current command circuit which converts the data value of the ROM 2 according to the command of the CPU 1 into an analog value in the D / A converter 3 and outputs the current command value I, the D / A converter ( 3) A / D converter (4) for receiving the current command value (I) from 3) and converting it into a digital value so as to be compared with the input digital value of the D / A converter (3). Fault detection and offset automatic control circuit of command circuit. ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
