Abstract
A method of controlling a motor operating a pumping apparatus of a system includes determining a trip value for a parameter, floating the trip value, and monitoring the operation of the pump. Monitoring the operation of the pump includes determining a value for the parameter, comparing the value to the trip value, and determining whether the comparison indicates a condition of the pump. The method of controlling the motor also includes controlling the motor to operate the pump based on the condition of the pump.
Claims15
A method of controlling a motor operating a pumping apparatus of a system, the pumping apparatus comprising a pump and the motor coupled to the pump to operate the pump, the method comprising:
- determining a trip value for a parameter;
- monitoring the operation of the pump, the monitoring act comprising
- determining a value for the parameter,
- comparing the value to the trip value, and
- determining whether the comparison indicates a condition of the pump;
- controlling the motor to operate the pump based on the condition of the pump;
- and
- floating the trip value throughout continuous operation of the pump, wherein floating the trip value includes calculating an average value with the value for the parameter over a period of time and determining a new trip value with the average value.
A method of controlling a motor operating a pumping apparatus comprising a pump and the motor coupled to the pump to operate the pump, the method comprising:
- determining a trip value for a parameter of the motor;
- monitoring the operation of the pump, the monitoring act comprising
- determining a value for the parameter,
- comparing the value to the trip value, and
- determining whether the comparison indicates a condition of the pump;
- controlling the motor to operate the pump based on the condition of the pump;
- and
- floating the trip value throughout continuous operation of the pump, wherein floating the trip value includes calculating an average value with the value for the parameter over a period of time and determining a new trip value with the average value.
