Abstract

A configurable motor controller includes solid state switches for connection between an AC line and motor terminals for controlling application of AC power to the motor. A control circuit controls operation of the solid state switches. The control circuit comprises a programmed processor for commanding operation of the solid state switches. A memory is connected to the programmed processor storing configuration information relating to operation of the solid state switches. A user configuration device selects the values for the stored configuration information. The configuration information comprises adjustable values within a range. The configuration device is adapted to select any adjustable value within the range.
