Embodiment Construction

[0012]One or more specific embodiments of the present disclosure will be described below. In an effort to provide a concise description of these embodiments, all features of an actual implementation may not be described in the specification. It should be appreciated that in the development of any such actual implementation, as in any engineering or design project, numerous implementation-specific decisions must be made to achieve the developers' specific goals, such as compliance with system-related and business-related constraints, which may vary from one implementation to another. Moreover, it should be appreciated that such a development effort might be complex and time consuming, but would nevertheless be a routine undertaking of design, fabrication, and manufacture for those of ordinary skill having the benefit of this disclosure.

[0013]When introducing elements of various embodiments of the present disclosure, the articles “a,”“an,”“the,” and “said” are intended to mean that there

Abstract

A method may include receiving, by respective processing circuitry of one or more power modules of an industrial automation device, a control signal from a controller of the industrial automation device. The power modules may include driver circuitry and a power converter that may provide power to a motor based on the signal. The method may also include, detecting, by the respective processing circuitry, a lack of communication from the controller based on the signal, and, in response to detecting the lack of communication from the controller, transmitting, by the respective processing circuitry, a first command to gating signal enable circuitry to disable the driver circuitry, and transmitting, by the respective processing circuitry, a second command to driver power circuitry to prevent power from being provided to the driver circuitry.
