Abstract

PURPOSE: To sufficiently make the control deviation small and to reduce the cost, by taking the sum of previous and residual output value and the new set value at the beginning of each repetition, in the numeric control servo unit performing the control operation repetitively.
CONSTITUTION: The set numerical value L is preset to the reversible counter 4 to input the measured numeral k according to the controlled variable and the difference is output. The output of the counter 4 is converted into analog amount at the D/A converter 5b to control the analog quantity to be reached zero at the control means 6, 7. At the biginning of each repetition of this control operation, the residual output value of the counter 4 and new set value are summed 3 and the result of addition is preset to the counter 4.
