    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: Control circuitry of a motor drive provides commands for operation of power circuitry based at least in part on signals exchanged with functional circuits, such as for system data and control data, such as feedback of motor or system parameters. The functional circuits may operate at different data rates, with different interrupt intervals, depending upon their capabilities. The control circuitry accommodates all of these flexibly. A physical backplane printed circuit board comprising independent data lines for each functional circuit allows for independent configuration of the data rates, interrupt intervals and communications between the control circuitry and the functional circuits.

    Abstract: The subject matter disclosed herein describes a switch embedded in a motor controller and a network protocol executing on the switch to provide communication between devices connected to the motor controller in a motor drive application. The embedded switch is configured to communicate via separate ports with an external controller, a network interface for the motor controller, additional motor controllers, and with the motor or other devices mounted on the motor. The network protocol includes a first tier for data that requires deterministic delivery at a high data rate, a second tier for data that requires a high delivery rate but is also tolerant of some variation in delivery time, and a third tier for data that may be delivered at a slower data rate. The embedded switch receives data at any port, identifies the communication tier to which the data belongs, and delivers it to another port accordingly.
