Abstract
An electric fader drive unit includes a drive portion, a fader position control portion, and an electric fader control portion. The drive portion drives an electric fader by supplying drive power to the electric fader. The fader position control portion indicates a target position of the electric fader. The electric fader control portion receives an indication of the target position from the fader position control portion, and, when controlling the drive portion to move the electric fader to the target position, moves the electric fader to the target position by changing the drive power maintained at preparation drive power less than the minimum drive power that is the lowest drive power required for moving the electric fader to a predetermined drive power not less than the minimum drive power.
