CA 2148633
Drive apparatus (10) for a dynamoelectric machine (M) for installation in an appliance (A) to provide a wide range of programmable features. In the preferred embodiment, the drive apparatus includes a machine drive (12) operatively connected to the dynamoelectric machine. The machine drive includes a microcontroller (14) having as a first and program memory (16) a ROM (read only memory) defining a processor module (13) for controlling machine operation during different appliance operating conditions, and as a second and data memory (18) an EEPROM (electrically erasable programmable read only memory) for storing machine and system operating characteristic information. Multi-position switches (SW1-SWN) are connected to the processor module. The switch functions are determined by a program stored in the program memory as further developed by data stored in the data memory. The switch settings, in combination with the program control, establish operating characteristics for the system. This allows an appliance manufacturer, for example, to select one set of functions or operating characteristics for the machine, and the value of the function selected by making one switch setting, while another different set of functions or operating characteristics, and other independent function valves are provided by making a different switch setting, or by a data memory change for the selected switch setting. The characteristics defined by the switches can be changed by changing the data in the data memory.
