The Gen4-series represent the absolute latest design concept for compact and reliable AC Controllers. They feature the smallest footprint in the industry for their power capability. The high efficiency of these controller makes it possible to integrate them into very tight spaces without sacrificing performance. The design has been optimized for the lowest possible cost while maintaining superior reliability in the most demanding applications.

The Gen4 controllers are designed to control either AC Asynchronous motors or PMAC Synchronous motors. This feature allows users to select optimal motor solutions for any application. Both UVW and encoder AB inputs are provided for maximum flexibility.
