Abstract: Control circuitry of a motor drive provides commands for operation of power circuitry in cooperation with peripheral circuits and devices, such as converters, inverters, feedback precharge circuits, feedback devices, interfaces, and so forth. The communications with the devices is handled by fiber optic communications circuitry that implements a flexible scheme of dynamic interval communication depending upon the capabilities and design of the peripheral circuit or device. The communication may be in accordance with a plurality of predetermined schemes, each having different data transfer rates, data allocations, and so forth. The schemes may each set communications protocols (e.g., timing) over a high speed interface between the fiber optic communications circuitry on one side and over fiber optic cables to the peripherals on another side.

Abstract: A motor drive configured to be connected to an external device is provided. The motor drive includes an outer housing, a power module housed within the outer housing, and a control module housed within the outer housing and in communication with the power module. The motor drive also includes a communications port disposed on the outer housing and in communication with the control module. The communications port supports dual-role power in which the motor drive powers the external device when the external device is of a first type and the motor drive receives power from the external device when the external device is of a second type.

Abstract: A tamper detection apparatus includes a switch and a tamper detection circuit with a non-volatile memory in an industrial product enclosure. In response to the switch detecting a door or panel of an industrial product enclosure being open when an electronic component or system in the enclosure is unpowered, the tamper detection circuit stores a tamper event code in the non-volatile memory. After the electronic component or system is powered, a system processor obtains the tamper event code from the tamper detection circuit and refrains from operating a machine or process pending reset of the industrial product by a user.

Abstract: Disclosed examples provide control boards with power systems that include a safety system with a protection circuit to selectively connect or disconnect first and second DC to DC converters to or from a DC input signal according to the DC input signal and a monitor signal, and a monitor circuit to provide the monitor signal according to the first and second DC to DC converter output signals.
