Abstract

PURPOSE:To eliminate the loss of the positioning time due to the conventional reciprocating motion to perform positioning in a short time, by stopping driving of the motor by the maximum speed reduction point, which is operated preliminarily before the start of positioning, to perform positioning. CONSTITUTION:The position before the start of positioning is denoted as A, and the target position is denoted as B, and the position where the motor is stopped from the negative-direction maximum speed state and the brake is put on, namely, the fixed speed reduction point is denoted as C. The position where the motor becomes the maximum speed instantaneously and the brake is put on to stop driving of the motor is denoted as C'. In the example of the control pattern in case when point A is positioned at the outside of point D, the device is moved to point C in a negative-direction constant speed by the damping operation; and when the device passes point C, driving of the motor is stopped, and the device is moved to point B by inertia while putting on the brake, thereby completing positioning.
