PURPOSE: A control method for a fixed type vertical louver blind is provided to stably and steadily open or close a fixed type vertical louver blind by stably supporting and mounting a louver tilting shaft and using rotational control which includes starting, constant-speed driving, and stopping processes. CONSTITUTION: A control method for a fixed type vertical louver blind comprises a starting process, a constant-speed driving process, and a stopping process. The starting process supplies a high signal of 50-80% for 1-10% of one rotation cycle of a vertical louver (1). The constant-speed driving process supplies a high signal of 30-50% for 80-98% of one rotation cycle of the vertical louver. The stopping process gradually decreases the supply of pulse control power from a high signal of 30-50% to a high signal of 10% for 1-10% of one rotation cycle of the vertical louver in order to gradually stop the vertical louver. |
