<p>A multiplier ratio DMR is calculated in advance by an operation unit (20) based on the moving amount (L) of a mechanical moving part per turn of the motor, moving amount (R) per pulse of moving instruction, and the number (N) of incremental pulses generated in an absolute position detect pulse coder (18) per turn of the motor. Moving instructions ( DELTA Rn) are integrated by a moving instruction integration unit (11), the absolute position (PA') of a machine produced from the absolute position detect pulse coder (18) is multiplied by DMR times, a difference (Er) between an integrated value (Pc) of moving instruction and a multiplied result (PA) is calculated as a positional error, and the rotation of the servo motor (17) is controlled based on the positional error.</p> |
