PROBLEM TO BE SOLVED: To provide a position controller capable of preventing processing failure by a control unit even when the speed is increased during precisely detecting the position by multiplying an encoder signal for position detection.SOLUTION: The position controller includes: signal generation means that creates a signal corresponding to the drive by a driver unit; multiply means that creates a multiply signal from the signal created by the signal generation means; and changing means that changes the multiplying number from the multiply means. The changing means aligns the phase of the multiply signal created by the multiply means before and after changing the multiplying number.SELECTED DRAWING: Figure 1 |
