Automatic Energy Optimization, AEO

One of the main reasons why variable frequency drives are used in HVAC systems is to maximize energy savings.

While the drive and fan or pump maintain a high level of efficiency at reduced speeds, the efficiency of the motor drops off as it becomes unloaded. A number of drive designs have attempted to improve the low speed efficiency of motors. Unfortunately, most of these techniques require tedious manual adjustment and still fail to optimize the motorís efficiency under all conditions.

The VLTģ 6000 has a unique control feature called Automatic Energy Optimization (AEO) which allows the drive to automatically maximize the motorís efficiency under all operating conditions. This section will examine the reason for the reduction of motor efficiency at light loads and the method that AEO uses to counteract this natural tendency. The application and limitations of this function will also be studied.
