Abstract
An airflow health predictive maintenance system and method for a motor drive includes a differential pressure sensor that senses an air pressure differential between a sensing location within an enclosed cabinet space of the motor drive and a reference location. The system includes an electronic control system configured to select a setpoint that indicates that airflow through the cabinet space has reached a value associated with a need for air filter maintenance. The control system is further configured to obtain air pressure differential measurements periodically from the differential pressure sensor and generate an actual trend comprising a series of values, wherein each of the values of the actual trend is derived from one or more of the air pressure differential measurements. The control system is also configured to project the actual trend to derive a projected trend based upon the series of values of the actual trend and compare the projected trend to the setpoint to predict an end of life event that can be used to determine a time when air filter maintenance is predicted to be required, wherein the end of life event is based upon a predicted intersection of projected trend with the setpoint.
