PURPOSE:To carry out a high-precision control without adjustment on the positional match of magnetic poles, by correcting a sine-wave command corresponding with the output data of correction data memory means. CONSTITUTION:So far as a counter (B) 20 is concerned, specified input is fed to a motor, and the motor is put in a locking state, and the phase difference for the then resolver feedback is counted and memorized as correction data. When a counter (A) 21 is reset, then the data of the counter (B) 20 are included for the readability each time, and the phase difference content only is always and continuously corrected. Accordingly, the adjustment on the positional match of magnetic poles cannot be required, and so the adjusting time can be saved, and the function is prevented from being lowered owing to adjustment and set error, and a high-precision control is obtained. |
