Abstract
A digital encoder control method of a digital control apparatus has a driving unit, a frequency signal generating unit for generating a pulse signal of a frequency according to a driving velocity of a driven member which is driven by the driving unit, an edge detecting unit for detecting a rising-up edge and a falling-down edge of the pulse signal, and a period data detecting unit for counting period data between edges detected by the edge detecting unit. Each time the edges are detected by the edge detecting unit, the period data between the same edges as the detected edges is outputted as control velocity data of the driving unit.
