The VLT 8000 Aqua Drives series is a variable frequency drive family developed for water and wastewater applications, with built-in functions aimed at pump control, pressure regulation, and energy-efficient operation on variable-torque loads.
Its control platform includes integral Automatic Energy Optimization, a built-in PID controller for closed-loop process control, and operating features such as sleep and wake-up behavior that support fluctuating demand in pumping systems. Standard communication capability includes an RS-485 port with FC protocol, while optional networking expands integration through Profibus, LonWorks, DeviceNet, and Modbus RTU. The series also supports cascade control arrangements that can sequence multiple pumps for lead-lag duty, staged operation, and pump alternation to improve overall system efficiency. Available accessories and configurations include remote control panel mounting, enclosure-related options, communication cards, relay expansion, and LC filters intended to reduce motor noise and improve output waveform characteristics in sensitive installations.
