Title: Positioning controller
Inventor: TADA NAOTO
IPC: G05D3/12
Filed: 1987-07-31
Abstract: PURPOSE:To prevent the generation of a positioning error without breaking the zero balance against a temperature variation, by providing an auto zero circuit for giving the correction quantity of the zero balance to an analog circuit, based on the error quantity generated in an error counter. CONSTITUTION:As a result of a data analysis, when it is discriminated that there is no movement, a processing for auto zero is executed. That is, when a time counter value T=0 is discriminated, an auto zero circuit 17 discriminates whether a count value of an error counter 5 is positive or negative. Subsequently, in accordance with a result of discrimination, the count number of a correction buffer is counted down or counter up, and thereafter, N is set to a value of the counter value T. Next, when a servo-motor M has stopped, the drift correction quantity is accumulated in the correction buffer in accordance with the discrimination of the count value of the counter 5, and a correction data is outputted to a D/A converter 11, therefore, the balance of the motor M is kept against all temperatures. In such a way, the generation of a positioning error can be prevented without breaking the zero balance against a temperature variation.
