    Abstract: A system may include one or more drives configured to receive a first alternative current (AC) voltage from a power source and provide a second AC voltage to one or more load devices. The system may further include one or more safety relay devices configured to couple the power source to the one or more drives and a communication device, where the communication device includes a processor. The processor may be configured to receive a first dataset via an Ethernet communication protocol, where the first dataset may include safety connection data indicative of one or more safety commands for controlling one or more operations of the one or more safety relay devices. The processor may further be configured to transmit a second dataset to the one or more safety relay devices via a subnet infrastructure, where the second dataset includes the one or more safety commands.

    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.

    Abstract: For power converter pre-charge with line synchronization, a method magnetizes a power transformer of a power converter with a supply voltage from a variable voltage variable frequency supply. The method pre-charges power cells of the power converter fed from the power transformer to a specified voltage with the supply voltage. The method further modifies a primary amplitude, a primary phase, and a primary frequency of a primary winding of the power converter with the supply voltage to match a main amplitude, a main phase, and a main frequency of a main voltage of a main power source. In response to matching the primary amplitude, the primary phase, and the primary frequency to the main amplitude, the main phase, and the main frequency, the method connects the main power source to the power transformer.
