Enclosures – IP20/chassis, IP21/NEMA 1, IP55/NEMA 12 and IP66/NEMA 4X
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 achieved quickly.
Automatic Energy Optimization – The standard feature AEO provides optimized motor magnetization at all speeds and loads. This increases energy efficiency by 5-15% for partial loads.
Energy monitoring – The VLT AQUA Drive provides a complete range of energy consumption information, which helps identify low-efficiency components in the system.
PM motor support – Support for any non salient permanent magnet motor up to 22 kW for better system efficiency.
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.
Deragging – Can be used as a proactive or reactive feature of the AQUA Drive for wastewater applications to prevent clogging of pumps. Deragging helps to avoid downtime and reduces maintenance cost.
Cascade controller solutions – The built-in standard cascade controller controls up to three pumps with a fixed lead pump. The optional Extended and Advanced Cascade Controller makes it possible to extend the number of pumps and ensure smooth staging/de-staging, also in mixed pump and variable speed pump applications.
Motor Alternation – This built-in logic controls alternation between two pumps in duty/stand-by applications. Motion of the stand-by pump prevents the pump from sticking. 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.
Check Valve Ramp – The Check Valve Ramp of the VLT AQUA Drive prevents water hammering as check valves close smoothly when the pump stops.
Quick Menu – The user-friendly Quick Menu and its submenus of the VLT AQUA Drive, saves time during drive configuration. The submenu “Water and Pumps” provides direct access to application specific features.
Safety – The VLT® AQUA Drive can optionally be delivered with the safe torque off (safe stop) functionality suitable for category 3, performance level d according to EN 13849-1 and SIL 2 according to IEC 62061/IEC 61508. This feature prevents the drive from starting unintended.
