ERROR DIAGNOSTICS AND PROGNOSTICS IN MOTOR DRIVES
First Claim
1. A motor drive, comprising:
- a controller configured to generate a control or communication signal for transmission to a component of an automation system; and
an interface configured to receive from the component an operational condition signal indicative of a fault in the component, wherein the controller comprises a processor configured to;
analyze the operational control signal; and
determine a likelihood of at least one fault causing the operational control signal.

Abstract
An automation network that utilizes motor drives to diagnose faults, and provide potential solutions to a user. The fault status and/or diagnostic remedies may be displayed via a user display integrated with (e.g., in a single cabinet with) the motor drives and/or coupled to (e.g., in an external device separate from) the motor drives. As such, a logic process or other algorithm may be executed by the motor drive to determine a potential set of solutions for any given fault, based on, for example, determined errors and likelihood of causes for presentation to a user. In this manner, motor drives may allow for user corrective actions to be communicated to a user.

22. A motor drive, comprising:
-
a controller configured to generate a control or communication signal for transmission to a motor of an automation system; an interface configured to receive an operational condition signal indicative of a fault in motor;
wherein the controller comprises a processor configured to;analyze the operational control signal; determine a likelihood of at least one fault causing the control signal; and determine a likelihood of a solution to remedy the fault based on the likelihood of the at least one fault causing the control signal; and a display, wherein the controller is configured cause an indication of the solution to be provided on the display. - View Dependent Claims (23, 24, 25, 26)
