Abstract

PURPOSE:To enable the accurate control by using microcomputer for the electric motor's control and controlling an incrementer/decrementer through the holding and comparison of electric motor's input information every moment. CONSTITUTION:The electric motor 100 is driven via a rectification circuit 175 and an inverter 160. Each signal of a phase detector 150, DC voltage, current, temperature and command is applied to an I/O circuit 120 controlled by microcomputers 114-118. In addition, reference registers containing an input information, instantaneous register, comparison circuit and a stage counter which inputs a comparative output to a comparative output latch group, are provided. These latch groups' output is caused to be held by another comparative output latch group, controlling the incrementer/decrementer. Thus the inverter 160 is controlled. For this reason, it is possible to control the incrementer/decrementer under assumption that their operation is accurate.
