Advantages of a medium voltage variable frequency system Reliability & availability Precise power delivery The higher reliability and lower maintenance needs of a variable speed drive system compared to gearboxes and hydraulic couplings result in lower lifecycle cost. In many applications, the superiority of electrical control simply cannot be matched by mechanical systems. Precise control of power means better outcomes, from the flatness of a steel sheet to the accuracy of offshore Oil & Gas exploration. Saving energy, caring for the environment In today’s world more than ever, energy...

Process control benefits Incoming power dip ride-through The MV7000 provides incoming power loss ride-through and keeps the process running without tripping. Under-voltage operation The MV7000 operates continuously and provides power to the motor at a lower input supply voltage (down to 70% of nominal voltage). Critical speed avoidance The MV7000 can be programmed for up to three critical frequency bands and ride-through these without any resonance issues. Independent acceleration and deceleration ramps The MV7000 can be be programmed into the drive controls as needed for controlled...
