Features and User Benefits
Auto-tuning of the PI controllers With auto tuning of the PI controllers, the drive monitors how the system reacts on corrections made by the drive - and learns from it, so that precise and stable operation is achieved quickly.
Pipe Fill Mode
Enables controlled (closed loop) filling of pipes. Prevents water hammering, bursting water pipes or blowing off sprinkler heads.
End of Pump Curve detects breaks and leakage
End of curve triggers an alarm, shuts off the pump, or performs another user-defined action.
Dry Pump Protection lowers maintenance costs
The VLT® AQUA Drive constantly evaluates the condition of the pump, based on internal frequency/power measurements.
This built-in logic controls alternation between two pumps in duty/stand-by applications. Motion of the stand-by pump prevents sticking of the pump. An internal timer assures equal usage of the pumps.
Reduces the pressure set point according to the flow - which saves energy.
The initial ramp provides fast acceleration of pumps to minimum speed, from where the normal ramp takes over. This prevents damage on thrust and bearings.
