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. Gain factors for PI are continuously changed to compensate for changing characteristics of the loads. This applies to each PI controller in the 4-menu sets individually. Exact P and I settings at start-up will not be necessary – which lowers the commissioning costs. Pipe Fill Mode Enables controlled (closed loop) filling of pipes. Useful in...

Dry Run Detection lowers maintenance costs The VLT® AQUA Drive constantly evaluates the condition of the pump, based on internal frequency/power measurements. Sleep Mode Sleep Mode keeps pump wear and power consumption to an absolute minimum. In low flow situations, the pump will boost the system pressure and then stop. In case of a too low power consumption – indicating a no or low flow situation – the VLT® AQUA Drive will stop. Monitoring the pressure, the VLT® AQUA Drive will restart when the pressure falls below the required level. Flow compensation The flow compensation feature in VLT®...

Harmonics dissipation solutions for water and wastewater plants Danfoss understands that water and wastewater treatment plants are frequently significant users of high power drives for pumps, compressors, aerators and so on, which by their very nature can generate substantial harmonic disturbance to the mains supply. This can be exacerbated when the plant is in an isolated location and supplied by a lengthy, high impedance power line. Add to this the fact that such plants also employ a great deal of sensitive electronic equipment such as sensors, telemetry, computer control systems and the...

cost-effective solution for your site, taking into consideration the installed load, the regulatory norms to be met, the diversity factor of your operations and the needs of your installation for a high quality supply. Danfoss also offers free MCT 31 Harmonic Calculation software to help you calculate the harmonics and power quality of your site. Calculate the harmonic disturbance Free to download, the VLT® Harmonic Calculation Tool MCT 31, is a simple to use, fast and accurate software tool for calculating the harmonic disrup- tion from your existing or intended drives installation.
