Abstract

PURPOSE:To make the residual oscillation as little as possible by 1 set of waveform memory, by making plural strokes correspond to the positioning time when their residual oscillation becomes little, so that the input energy becomes almost equal. CONSTITUTION:In accordance with a stroke command, the necessary stroke amount is inputted to the multipiler 7 from the stroke memory 2, and it is multiplied by the reference amount of the reference memory 1. Also, the positioning time T1i is decided through the logical circuit 3, 1/T1i<2> is outputted from the memory 4, and it is multiplied by the output of the multiplier 7, by the multiplier 8. Also, the output of the circuit 3 is provided to the clock generator 5, too, and the input waveform Fn is outputted from the memory 6 of the input waveform pattern by a pulse of the generator 5. The waveform Fn is multiplied by the output of the multiplier 8 by the multiplier 9. As a result, a current waveform in case of positioning by the time T1i can be obtained by the multiplier 9. The output of this multiplier 9 is converted to an analog amount by the D/A converter 10, and it is provided to the motor system 12 after the power amplification 11.
