    However, knowing the load at a given frequency in an installation is often a problem. This problem can be sol-ved by using a VLT 4000 VT with its integral Automatic Energy Optimization (AEO), which ensures optimum energy utilization. All VLT 4000 VT units feature this function as a factory setting, i.e.
