Danfoss Drives: Variable-Frequency Drive
July 23, 2007
The VLT® Micro Drive is a general-purpose variable-frequency drive designed for rugged, reliable, plug-and-play control of ac motors up to 3 hp. To use, connect the motor and power cables, turn the control knob, and watch the motor speed change. According to the manufacturer, the drive eliminates the need for an external controller and offers true side-by-side mounting without any derating due to its compact book-style design. An Automatic Energy Optimizer function allows the drive to consume less energy while the Automatic Motor Adaptation feature leverages the motor’s full operating potential. The drive features a smart logic controller, which allows users to program the controller to react on virtually any event, often eliminating the need for a PLC. Additional features include built-in ac and dc brake functions. The drives are available in single-phase 200-240 vac, 0.25-2 hp; three-phase 200-240 vac, 1/3-2 hp; and three-phase 380-480 vac, 0.5-3 hp power range configurations.
