<p>PURPOSE:To relieve the load of the software controlling a pulse output considerably and to quicken the response speed by synthesizing both outputs from a timer system driving the time axis direction of each output phase and a timer system applying parallel drive of the direction of output phase. CONSTITUTION:Timers 13-15 for driving each phase pulse and registers 16-18 are used and an output of a full phase pulse drive timer 11 and a register 12 is superimposed on pulse outputs 19-21 controlled independently of each phase. The periods A, B are periods when parallel processing is applied by an output of the register 12. The length of the periods A, B is set by the full phase pulse driver timer 11 in advance and a synthesized waveform is automatically obtained by having only to start the full phase pulse driver timer 11 by the software or an external trigger as required. Thus, the output of the register 12 is able to be superimposed only on the selected output phase, not on all the pulse outputs 19-21 depending on a value programmed in the register 12.</p> |
