The phase delay of current flowing into a servo motor is prevented by using the apparatus. The apparatus includes a flip-flop(14) for counting the duration from initial power on to Z signal input, a 3-bit multiplexor(15) for outputting lower 3 bits of input selection signal, a latch(16) for latching the most significant bits output signals of the 3-bit multiplexor and the flip-flop, D/A converters(11,13) for multiplying ROM data and torque command, and a sequential signal generator(18) for providing ROM data to the D/A converter. |
