    １．General 1-1 Features Controller (CEU2) is a special controller designed for Monosashi-kun with Brake. Upon the input, controller will stop the cylinder, smoothly and precisely at position as inputted. Stopping positions of Monosashi-kun with Brake are stored into “Step”, ranging from step 1 to 32. Steps will be grouped together and form as “Program”.
