Zusammenfassung:Functional safety techniques for industrial automation devices are provided. A method may include receiving, by respective processing circuitry of one or more power modules of an industrial automation device, control signals from a controller of the industrial automation device. The power module may include driver circuitry and a power converter that may provide power to the motor based on the signal. The method may also include detecting, by the respective processing circuitry, whether there is a lack of communication from the controller based on the signal, in response to detecting that there is a lack of communication from the controller, sending, by the respective processing circuitry, a first command to the strobe signal enable circuitry, the first command to disable the driver circuitry, and transmitting, by the respective processing circuitry, a second command to disable the driver circuitry. And sending, by the respective processing circuitry, a second command to the driver power circuitry, the second
