Abstract: A disconnect override circuit for a power conversion system includes a first input coupled to a user disconnect switch to receive a disconnect input signal, as well as a second input coupled to a motor drive or motor starter to receive a fault signal, and a third input adapted to receive an override signal. The disconnect override circuit has an output configured to provide a disconnect control output signal to control a user disconnect circuit according to the disconnect input signal, the fault signal and the override signal, the output signal having a first state to cause the user disconnect circuit to allow power transfer from the AC input to the motor drive or motor starter, and a second state to cause the user disconnect circuit to prevent power transfer from the AC input to the motor drive or motor starter.

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.
