AntiSway Effortless and stable load control GH SOLUTION: ATV+AntiSway • Reduction of load swaying, through a simple solution: software integrated in the crane variable speed drives. • Reduces swaying due to acceleration and braking. • Effective for the movement of the trolley and the bridge. • Easy to set up and use. No subsequent adjustments required. • Easy retrofitting to existing cranes by loading the firmware onto the variable speed drives. Greater speed + Greater precision = Increased Productivity and Safety. Without complicating things for the operator: the system reduces the swaying automatically. HOW IT WORKS 1 Inputs: / Operator’s commands for bridge and/or trolley movement (accelerate/decelerate). / Trolley and crane speeds. 2 Algorithm integrated in the firmware of the variable speed drives that control the trolley and bridge motors. The algorithm determines the optimal acceleration and deceleration ramps to reduce swaying. 3 Each drive controls the movements independently. 4 Return to point 1. 2. The algorithm determines 3. Each drive manages the optimal acceleration and deceleration ramps to reduce swaying. TECHNICAL DETAILS The anti-sway software is included in the firmware of the Schneider ATV 320 variable speed drives. After initial configuration, it performs acceleration/deceleration ramps autonomously – Requires no additional sensors or PLCs – Minimal maintenance – Open-loop control: it will not detect or correct swaying due to external causes – Automatically disconnects at slow speed to facilitate load positioning – Allows reconfiguration, disconnection and reconnection by physically accessing the drives.
