Abstract
A motor controller and methods of controlling a variable speed motor using the motor controller after a power-loss event are described. The motor controller is configured to be coupled to a motor. The motor controller includes a computing device configured to determine power is being supplied to the motor controller a power-loss event. The computing device is also configured to operate the motor in accordance with a predetermined operating schedule such that the computing device operates the motor at a first speed for a first time period, and after completion of the first time period, the computing device operates the motor at a second speed for a second time period.
Claims20
A motor controller configured to be coupled to a variable speed motor, said motor controller comprising a computing device configured to:
- determine power is being supplied to the motor controller after a power-loss event;
- and
- operate the motor in accordance with a predetermined operating schedule such that said computing device operates the motor at a first speed for a first time period, and after completion of the first time period, said computing device operates the motor at a second speed for a second time period.
A method of controlling a variable speed motor using a motor controller after a power-loss event, the motor controller including a computing device, said method comprising:
- determining, by the computing device, that power is being supplied to the motor controller after a power-loss event;
- and
- operating, by the computing device, the motor in accordance with a predetermined operating schedule, such that the computing device operates the motor at a first speed for a first time period, and after completion of the first time period, the computing device operates the motor at a second speed for a second time period.
A computer-readable storage device having processor-executable instructions embodied thereon, enabling control of a variable speed motor using a motor controller after a power-loss event, the motor controller including a computing device, wherein when executed by the computing device, the processor-executable instructions cause the computing device to:
- determine power is being supplied to the motor controller after the power-loss event;
- and
- operate the motor in accordance with a predetermined operating schedule such that the computing device operates the motor at a first speed for a first time period, and after completion of the first time period, the computing device operates the motor at a second speed for a second time period.
