Why Use the AntiSwayOpenLoop_2 Function Block?
The AntiSwayOpenLoop_2 function block helps to prevent sway of suspended loads on industrial cranes by calculating an optimal speed profile for horizontal movement of the trolley and/or the bridge. It is suitable for both, manually operated and automatic cranes.
Substantial reduction of load sway considerably increases the comfort of crane operation. It also shortens the time for crane operations and increases its productivity.
When used on an automatic crane the FB co-operates with the positioning system to arrive at a target position with significantly limited residual sway in the load.
This FB is an optimization of the AntiSwayOpenLoop FB. There are several modifications to solve unit issues with the existing library and modify the reaction time of the non-sway movement.
This function block is intended to have significant influence on the physical movement of the crane and its load. The application of this function block requires accurate and correct input parameters in order to make its movement calculations valid and to avoid hazardous situations. If invalid or otherwise incorrect input information is provided by the application, the results may be undesirable.
