The Varispeed G7 inverter covers all demands. With its five control modes it can handle every task, from simple things like pump and fan control, all the way through to high performance tasks such as positioning. It is the world’s first inverter using the 3-level-technology with IGBTs in the 400V class. By switching only half the DC bus voltage at a time, this technology greatly reduces the stress for the motor winding insulations, especially with long motor cables. Thanks to the much lower shaft voltage and bearing currents the Varispeed G7 lengthens the motor lifetime, even with non-insulated standard bearings. The autotuning functions with non-rotating motor helps you to start up your machine in the shortest possible time. The variety of analogue and digital I/O functions makes the drive suitable for nearly every application.
