A frequency inverter is the appropriate motor control device for continuous speed adjustment. In contrast to the soft starter, it does not operate the motor rigidly on the mains at a constant frequency, but regulates both the operating voltage and the operating frequency and can therefore run the motor energy-efficiently over a wide speed range. A regenerative frequency inverter also offers the possibility of recovering the braking energy, i.e. feeding it back into the supply.
