One or more embodiments of the invention include a pump controller that can perform a self-calibrating procedure, can provide precise motor speed control, can provide a limp mode before shutting down the motor when system parameters are exceeded andor fault conditions occur, can detect fault conditions, and can store fault conditions for later retrieval. The pump-motor assembly is generally submerged in the well at the end of a drop pipe. To maintain a constant supply pressure, the water systems also typically include a pressurized storage tank and a pressure switch that causes the motor to run when the pressure in the water system is low. The pressurized storage tanks are often relatively large, so that the motor does not need to be turned on and off frequently. Each embodiment of the present invention achieves one or more of these results. The method can include operating the motor in a forward direction, sensing a pressure in the water distribution system, determining whether the sensed pressure has increased by a pressure increment, increasing an operating frequency of the motor by a frequency increment if the sensed pressure has not increased by the pressure increment, and storing a speed of the motor as a minimum calibrated speed value if the sensed pressure has increased by the pressure increment. The method can include measuring an actual pressure in the water distribution system; determining whether the actual pressure is less than, greater than, or equal to a pre-set pressure value; subtracting the actual pressure from a desired pressure to determine a pressure error if the actual pressure is less than or greater than the pre-set pressure value; determining an integral of the pressure error; multiplying the integral by an integral gain to determine a first value; multiplying the pressure error by a proportional gain to determine a second value; summing the first value and the second value; and generating an updated speed control command based on the sum of the first value and the second value. The limp mode method can include measuring a parameter (e.g., a bus current, a bus voltage, a line current, andor a temperature) and determining whether the parameter is greater or less than a threshold. ![]() These methods can include bus over-voltage detection, bus over-current detection, dry-running detection, over-temperature detection, high or low-speed foreign-object jamming detection, and pressure sensor failure detection. In some embodiments, the invention provides a method of creating a fault log and storing fault condition codes for later retrieval. However, it should be noted that the embodiments of the invention as disclosed in the accompanying drawings are illustrated by way of example only. The various elements and combinations of elements described below and illustrated in the drawings can be arranged and organized differently to result in embodiments which are still within the spirit and scope of the present invention. The invention is capable of other embodiments and of being practiced or of being carried out in various ways. Also, it is to be understood that the phraseology and terminology used herein is for the purpose of description and should not be regarded as limiting. ![]() The terms mounted, connected and coupled are used broadly and encompass both direct and indirect mounting, connecting and coupling. Further, connected and coupled are not restricted to physical or mechanical connections or couplings and can include electrical connections and couplings, whether direct or indirect. However, one of ordinary skill in the art, and based on a reading of this detailed description, would recognize that, in at least one embodiment, the electronic based aspects of the invention may be implemented in software. As such, it should be noted that a plurality of hardware and software based devices, as well as a plurality of different structural components may be utilized to implement the invention. Furthermore, and as described in subsequent paragraphs, the specific mechanical configurations illustrated in the drawings are intended to exemplify embodiments of the invention and that other alternative mechanical configurations are possible. In some embodiments, the pump 10 is a submersible pump for use in residential or commercial well pump systems. In other embodiments, the pump 10 is a pump for use in pool or spa systems. In still other embodiments, the pump 10 is a pump for use in residential or commercial water distribution systems that are connected to a municipal water system.
