Description
The CUE is a series of frequency converters designed for speed control of Grundfos pumps. CUE offers several pre-set application control modes, including constant pressure, constant level (with or without stop function), proportional differential pressure, proportional pressure, and constant temperature. These pre-configured control modes make it easier to program the drive for specific applications. When the system is controlled externally, the open loop control mode is used, providing the CUE with the necessary speed information.
