Abstract

PURPOSE:To decrease the number of bits of a D/A converter and at the same time to vary the saturation value of the servo characteristics, by limiting the input value to the D/A converter by means of a variable limiter means. CONSTITUTION:An operator sets the limit numerical value to a variable limiter command means LM, and this set value is supplied to comparators CO1-CO3 plus selectors S1-S3 via registers BR1-BR4. Each of these comparators CO1- CO4 performs the comparison of the numerical value and supplies the decision output to a comparator CO5 to carry out the checking. With this checking, the comparator CO5 delivers a selection signal SL to decide the output signal of each of the selectors S1-S4. In such way, the value more than the set value which is supplied to a D/A converter DAC is set forcibly to the value coincident with the set value. As a result, the limit value can be freely selected in a range of the maximum value corresponding to the number of bits of the D/A converter.
