Abstract

An data interface module is provided for allowing a user to remotely modify a predetermined number of operating parameters of a motor driven by a motor control and for displaying the same. The interface module includes a micro-controller interconnected to a communications network and a visual display structure. The visual display structure has a first screen which displays a scrollable list of the operating parameters and a second screen which displays a data value for a user selected one of the operating parameters. A user may modify the user selected operating parameter when the second screen is displayed.

Claims

a micro-controller interconnected to the visual display structure; and

a screen selection device operatively connected to the visual display structure for allowing a user to toggle between the first and second screens;

wherein the micro-controller downloads the user scrollable list of operating parameters from the motor control.

2. The data interface module of claim 1 further comprising:

a micro-controller interconnected to the visual display structure; and

a communications link interconnecting the micro-controller to the communications network, the communications link receiving a predetermined packet of data from the motor control corresponding to the data value of the user selected operating parameter and providing the same to the micro-controller whereby the micro-controller causes the visual display structure to display the data value of the user selected operating parameter on the second screen.

3. The data interface module of claim 2 further comprising a data value adjustment device operatively connected to the micro-controller for adjusting the data value of the user selected operating parameter displayed to a user selected data value.

4. The data interface module of claim 3 wherein the data value adjustment device includes a shaft encoder wherein rotation of the shaft encoder varies the data value of the user selected operating parameter of the motor.

5. The data interface module of claim 1 further comprising a memory storage device operatively connected to the micro-controller for storing the user scrollable list of operating parameters.

6. The data interface module of claim 5 wherein the memory storage device includes a serial EEPROM, the serial EEPROM interfaced to the micro-controller by a serial peripheral interface.

7. The data interface module of claim 1 wherein the visual display structure includes a liquid crystal display.

8. The data interface module of claim 1 wherein the screen selection device includes pushbutton movable between a first non-depressed position and second depressed position wherein pressing of the pushbutton into the depressed position toggles the visual display structure between the first and second screens.

9. The data interface module of claim 1 wherein at least one of the screens of the visual display structure displays an operating direction for the motor.

10. The data interface module of claim 9 further comprising a motor direction scrolling device operatively connected to the visual display structure for changing the display of the operating direction of the motor.

11. The data interface module of claim 10 further comprising a motor direction selection device operatively connected to the micro-controller for changing the operating direction of the motor to the operating direction displayed.

12. The data interface module of claim 1 further comprising a stop selection device movable between a first non-depressed and a second depressed position wherein pressing the stop selection device to the depressed position stops the motor.

13. A data interface module for allowing a user to modify the value of a predetermined operating parameters for a motor driven by a motor control and for displaying the value of the operating parameters, the motor control being operatively connected to a communications network, comprising:

a micro-controller for generating adjustment signals to adjust the value of a user selected operating parameter of the motor and for downloading a predetermined list of operating parameters for the motor from the motor control;

a communications link for interconnecting the micro-controller and the communications network to transmit the adjustment signals to the motor control;

a visual display structure operatively connected to the micro-controller, the visual display structure selectively displaying one of a plurality of user selected screens, the user selected screens including a user scrollable first screen for displaying at least a portion of the predetermined list of operating parameters for the motor and a second screen for displaying the value of the user selected operating parameter;

a screen selection device operatively connected to the visual display structure for allowing a user to toggle between the first and second screens; and

a parameter value adjustment device operatively connected to the micro-controller and having a plurality of discrete settings, the micro-controller

generating the adjustment signal in response to setting of the parameter value adjustment device.

14. The data interface module of claim 13 wherein the micro-controller includes an universal asynchronous receiver/transmitter.

16. The data interface module of claim 14 further comprising a depressible motor direction scrolling device operatively connected to micro-controller, wherein the micro-controller causes the visual display structure to sequentially display each operating direction of the motor in response to depression of the motor direction scrolling device.

17. The data interface module of claim 16 further comprising a motor direction selection device operatively connected to the micro-controller for changing the operating direction of the motor to the operating direction displayed.

18. The data interface module of claim 13 wherein the micro-controller adjusts the display of the value of the user selected operating parameter in response to the setting of the parameter value adjustment device.

19. The data interface module of claim 13 wherein the parameter value adjustment device includes a shaft encoder wherein rotation of the shaft encoder varies the setting of the parameter value adjustment device.

20. The data interface module of claim 13 wherein at least one of the screens of the visual display structure displays an operating direction for the motor.

21. The data interface module of claim 13 further comprising a stop selection device movable between a first non-depressed and a second depressed position wherein pressing the stop selection device to the depressed position stops the motor.
