Dedicated water features 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 achie ved 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
The feature detects breaks and leakage. End of curve triggers an alarm, shuts off the pump, or performs another userdefined action.

Dry Pump Protection lowers maintenance costs
The VLT AQUA Drive constantly evaluates the condition of the pump, based on internal frequency/power measurements.

Standard cascade controller
The in-built cascade controller controls up to three pumps with fixed lead pump.

Motor Alternation
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.

Flow compensation
The flow compensation feature reduces the pressure set point according to the flow - which saves energy.

Initial/Final Ramp
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. Sensorless Pressure or Flow Control

Safety
The VLT AQUA Drive can optionally be delivered with the safe stop functionality suitable for category 3 installations according to EN 954-1. This feature prevents the drive from starting unintended
