Abstract

A motor system controller and a method of operating the controller are provided that enable automatic (i.e., without further user intervention), sequential display of selected parameter values. The controller includes a memory that stores a plurality of operating parameters associated with the motor system controller and a computer program. The controller also includes a user interface having an operator keypad and a liquid crystal display. The operator keypad can be used to access the memory and select certain of the operating parameters for sequential display. The computer program then works with the display to automatically, sequentially display values associated with the selected parameters. The method includes the steps of selecting parameters from a plurality of operating parameters associated with the motor system controller and automatically, sequentially displaying values associated with the selected parameters.

Claims

1. A method of operating a motor system controller having a plurality of operating parameters associated therewith, comprising the steps of:

selecting a first parameter from said plurality of operating parameters using a user interface;

selecting a second parameter from said plurality of operating parameters using said user interface

to thereby form a modifiable subgroup of actively displayable parameters;

displaying a first value associated with said first parameter of said subgroup;

automatically displaying a second value associated with said second parameter of said subgroup after said first value is displayed for a predetermined period of time; and

,

repeating said step of displaying a first value and said step of displaying a second value after values associated with each parameter in said subgroup have been displayed.

2. The method of claim 1 wherein said second value is displayed for said predetermined period of time.

3. The method of claim 1 wherein said step of selecting a first parameter includes the substeps of:

accessing said first parameter in a memory; and

marking said first parameter.

4. The method of claim 1 further comprising the step of setting a scroll enable flag.

5. The method of claim 4 wherein said setting step includes the substeps of:

accessing said scroll enable flag in a memory; and

modifying said scroll enable flag.

6. The method of claim 1, further comprising the substep of activating a scrolling program in a memory.

7. The method of claim 1, further comprising the steps of:

selecting a third parameter from said plurality of operating parameters using said user interface, said subgroup including said third parameter; and

,

automatically displaying a third value associated with said third parameter of said subgroup after said second value is displayed.

8. A method of operating a motor system controller having a plurality of operating parameters associated therewith, comprising the steps of:

selecting a first parameter from said plurality of operating parameters using a user interface;

selecting a second parameter from said plurality of operating parameters using said user interface

to thereby form a modifiable subgroup of actively displayable parameters;

setting a scroll enable flag;

activating a scrolling program;

displaying a first value associated with said first parameter of said subgroup;

automatically displaying a second value associated with said second parameter of said subgroup after said first value is displayed for a predetermined period of time; and

,

repeating said step of displaying a first value and said step of displaying a second value after values associated with each parameter in said subgroup have been displayed.

9. The method of claim 8 wherein said second value is displayed for said predetermined period of time.

10. The method of claim 8 wherein said step of selecting said first parameter includes the substeps of:

accessing said first parameter in a memory; and

marking said first parameter.

11. The method of claim 8 wherein said setting step includes the substeps of:

accessing said scroll enable flag in a memory; and

modifying said scroll enable flag.

12. The method of claim 8, further comprising the steps of:

selecting a third parameter from said plurality of operating parameters using said user interface, said subgroup including said third parameter; and

,

automatically displaying a third value associated with said third parameter of said subgroup after said second value is displayed.

13. A motor system controller, comprising:

means for selecting a first parameter and a second parameter from a plurality of operating parameters associated with said motor system controller to thereby form a modifiable subgroup of actively displayable parameters; and

means for displaying a first value and a second value associated with said first parameter and said second parameter of said subgroup, respectively,

wherein said second value is automatically displayed after said first value is displayed for a predetermined period of time and said first value is again displayed after values associated with each parameter in said subgroup have been displayed.

14. The motor system controller of claim 13 wherein said selecting means includes an operator keypad.

15. The motor system controller of claim 13 wherein said displaying means includes a liquid crystal display.

16. The motor system controller of claim 13, further comprising a memory having a scrolling program.

17. The motor system controller of claim 13 wherein said second value is displayed for said predetermined period of time.

18. The controller of claim 13 wherein said selecting means includes means for selecting a third parameter from said plurality of operating parameters associated with said motor system controller, said subgroup including said third parameter, and said displaying means includes means for displaying a third value associated with said third parameter of said subgroup, said third value automatically displayed after said second value is displayed.
