Abstract
A system and method for replacing a sixteen-pin ECM with a non-sixteen-pin, field adjustable ECM in an HVAC or other system, and adjusting the performance of the replacement motor at the point of installation. A converter module receives programming information from an existing control board via an existing sixteen-pin harness, and converts the information to six signals. The module includes potentiometers for tuning speed/torque for first and second settings, adjusting a horsepower output of the replacement ECM, and adjusting a ramp time to increase or decrease a rate at which the speed/torque changes. The module includes switches for selecting between clockwise and counterclockwise directions for the replacement ECM, selecting between PWM and non-PWM control, and selecting between torque and speed modes. A non-sixteen-pin motor controller receives the information from the converter module via a four-wire harness, translates the information, and outputs a control signal to the replacement ECM.
