<p>PURPOSE:To shorten the processingtime by executing the interruption processing at the time of pulse output through macro service processing. CONSTITUTION:A pulse width modulating inverter controller is constituted of a microcomputer 1, a driver circuit, and a drivingunit, corresponding to an induction motor. The microcomputer 1 is constituted of ALU5, a general-purpose resistor 6, a PSW7, a ROM8, a PC9, an execution control part 10 by muROM 10a and MSEQ10b, an INTC11, a pulse control part 12, and a RAM 13. And this pulse control part 12 is equipped with an FRC, etc., and the INTC11 is equipped with interruption and i/o control circuits, etc., and through macro sevice processing, this performs interruption processing at the time of pulse output of a puse width modulation signal.</p> |
