CONTROLLER FOR A MOTOR AND A METHOD OF CONTROLLING THE MOTOR
First Claim
1. A method of controlling a pumping apparatus for a jetted-fluid system comprising a vessel for holding a fluid, a drain, and a return, the pumping apparatus comprisinga pump having an inlet fluidly connectable to the drain to receive the fluid, and an outlet fluidly connectable to the return to exhaust the fluid, anda motor coupled to the pump to operate the pump, the method comprising:
- controlling the motor to operate the pump;
monitoring the operation of the pump, the monitoring act comprisingmonitoring an output power of the motor, anddetermining whether the monitored output power indicates a condition of the pump; and
controlling the motor to operate the pump based on the condition of the pump and zero or more other conditions.

Abstract
A method of controlling a motor operating a pumping apparatus of a fluid-pumping application. The pumping apparatus includes a pump having an inlet to receive a fluid and an outlet to exhaust the fluid, and the motor coupled to the pump to operate the pump. The method includes the acts of controlling the motor to operate the pump and monitoring the operation of the pump. The monitoring act includes monitoring a power of the motor, and determining whether the monitored power indicates an undesired flow of fluid through the pump. The method further includes the act of controlling the motor to cease operation of the pump when the determination indicates an undesired flow of fluid through the pump and zero or more other conditions exist.
