Automatic Energy 
Optimisation
The standard feature AEO provides 
optimized motor magnetization at all 
speeds and loads.
This optimization program increases 
the energy savings gained by applying 
variable speed control.
Automatic Motor Adaptation
Enter the name plate data, and VLT® 
HVAC Drive automatically adjusts to 
the motor. 
Suitable for “follower” 
operation
The drive’s modular structure makes it 
suitable for “follower” operation 
mastered by BMS, PLC’s or DDCs. 
The real eff ect of VLT® HVAC drives is
