NXGPro+ Control Description

Control Descriptions Introduction

The NXGpro control monitors input power conditions and status, coordinates all power
components, controls output power to the motor, and performs special functions such as
integration into a process and transferring motors synchronously to and from power lines. At the
same time, the control protects the drive, the connected system process and the motor. With
specially equipped cells, the control also allows the cells to cleanly regenerate power back into
the input power feed.
