Mitsubishi Electric frequency inverter FR-A800 Plus is suited for various cranes to achieve fast, robust, and smooth operations. By using the Mitsubishi’s original anti-sway control technology, the swinging of an object moved by a crane is suppressed at the time of stopping, even without operator’s input adjustment. This control cuts down the tact time and facilitates efficient operation.
