PCT No. PCT/JP89/00355 Sec. 371 Date Dec. 14, 1989 Sec. 102(e) Date Dec. 14, 1989 PCT Filed Apr. 4, 1989 PCT Pub. No. WO89/10590 PCT Pub. Date Nov. 2, 1989.An improved servomotor control method where a multiplier ratio DMR is computed in advance by an arithmetic unit (20) from a traveling distance L of a movable machine element per revolution of a servomotor, a traveling distance R per pulse of a move command, and a number N of incremental pulses generated by an absolute position-detecting pulse coder (18) per revolution of the servomotor. A move command ( DELTA Rn) is accumulated by a move command accumulator (11), an absolute position (PA') output by the absolute position-detecting pulse coder (18) is multiplied by the multiplier ratio DMR. A difference (Er) between a value (Pc) obtained by accumulating the move commands and the result (PA) of the multiplication operation is computed as a position error, and rotation of the servomotor (17) is controlled by using the position error.
