The present disclosure relates to an apparatus for controlling multiple inverters and an inverter system including the same. The apparatus according to the present disclosure determines a motor having the smallest operation time among motors which are not being operated as a main motor to thereby transmit a running reference and a frequency reference to the corresponding main motor, if a speed of a main motor which is being operated is above a speed set by a user and a feedback is below a predetermined level.

A commissioning method, tool and computer-readable storage media for an industrial device are proposed. A commissioning method for an industrial device includes: determining application type of the industrial device; displaying at least one macro relevant to the application type determined for a user to choose. A displayed macro includes a set of defined parameters of the industrial device relevant to the application type determined. Finally, the commissioning method includes receiving the choice of the user on macro.

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.
