<p>A stepping motor control device, wherein a micro-stepping drive part (16) is selected in a first operation mode, the output from the micro-stepping drive part (16) is applied to a drive part (21) through a command value selector (12), and a stepping motor (25) is driven micro-steppingly by the drive part (21); a forced drive part (15) is selected in a second operation mode, the output from the forced drive part (15) is applied to the drive part (21) through the command value selector (12), and the stepping motor (25) is driven forcibly by the drive part (21), i.e., the high speed rotation of a rotor (29) is started from any rotating angle by a micro-stepping drive; and further a drive pattern generating part (13) is selected in a third operation mode, the output from the drive pattern generating part (13) is applied to the drive part (21) through the command value selector (12), and the high speed rotational driving of the stepping motor (25) is continued by the drive part (21).</p> |
