PROBLEM TO BE SOLVED: To automatically set the optimum value of a commutation offset value not through manual work as the optimum value of the revolution of a motor. SOLUTION: This method of auto-tuning a motor driver is the one which automatically preserves the maximum value of the revolution of a motor (3) as an optimum value (11) by automatically increasing the amount of increase of offset of the commutation offset value (10). |
