A wide dynamic range A built-in thermal shutdown circuit installed. A built-in mute circuit installed. (This circuit can mute the outputs of the drivers except for those for loading motors.) The power supplies for PreVcc, the actuator part, the loading part, and PowVcc of the feed motor part/spindle motor part are provided independently to achieve an efficient drive.
