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: A method may include receiving, via a processor, a request to enable movement of a rotor. The method may involve sending a first signal to a mechanical relay system in response to receiving the request, such that the second signal may cause a mechanical relay to close.

The solid-state relay system may couple a second conductor to the EM brake, such that the EM brake may open after receiving power via the first conductor and the second conductor.

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: Control circuitry of a motor drive provides commands for operation of power structure 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 power stage circuitry configured for the caliber system.

A first of these protocols may be based on a low voltage differential signal scheme, and another on a non-differential signal scheme, such as a negative bus reference scheme. The particular protocol selected may be based on detection of a voltage of a connector pin, and the selection and implementation may be fully automated.

Abstract: Systems and methods are provided for performing diagnostic testing for multiple motor drives operating in parallel. In one embodiment, the diagnostic testing may involve determining which of the multiple motor drives are in operation and communicating the active configuration of motor drives to testing circuitry. The testing circuitry generates an enable input signal transmitted to the transistor gates in each of the active motor drives. The testing circuitry also generates a power supply input signal transmitted to a DC to DC converter in each of the active motor drives. The responses to the enable input signal and the power supply input signal are measured to determine safety compliance.
