Abstract: A drive control device includes: an input unit of a command; and a control unit setting a period for rising a current in an inductive load to first and third periods in first and second commands, and setting a period for falling the current to second and fourth periods in the first and second commands, respectively. When the first command is changed to the second command, and at least one middle PMW pulse is disposed between a forward PWM pulse corresponding to the first command and an after PWM pulse corresponding to the second command, the control unit sets fifth and sixth periods in the middle PWM pulse corresponding to the first and second periods of the forward PWM pulse to a length between the first and second periods in the forward PWM pulse and the third and fourth periods in the after PWM pulse, respectively.
