A system for manufacturing an industrial automation drive includes a carrier frame configured to hold one or more semiconductor devices for use in the industrial automation drive. The carrier frame includes a set of fasteners disposed around an internal wall of the carrier frame such that each fastener of the set of fasteners includes an angled edge and a horizontal edge. Each fastener of the set of fasteners is configured to toollessly couple a power circuit board having the semiconductor devices to the carrier frame by bending from a first position when the power circuit board is pushed against the angled edge and returning to the first position when the power circuit board is pushed past the horizontal edge.

Systems and methods for manufacturing industrial automation drives

An electrical insulation configuration for an electrical device having a power circuit includes a first insulation device to provide a level of basic insulation between the power circuit and a user, and an additive insulation device in series with the first insulation device, the additive insulation device to increase the level of basic insulation to a level of double insulation or reinforced insulation between the power circuit and the user.

Electrical insulation configuration for an electrical device

A drive circuit for delivering high-level power to a load, and method of stopping a high power load from operating, are disclosed. The drive circuit includes a high power circuit capable of being coupled to the load and delivering the high level power thereto, and a to power circuit that controls the high power circuit. The low power circuit includes a first circuit portion that provides at least one control signal that is at least indirectly communicated to the high power circuit and that controls the delivering of the high level power by the high power circuit, and a second circuit portions coupled to the first circuit portion. The second circuit portion is capable of disabling the first circuit portion so that the at least one control signal avoids taking on values that would result in the high power circuit delivering the high level power to the load.

Apparatus and method for disabling the operation of high power devices

Integrated AC regenerative motor drives and operating methods are presented in which a precharging circuit is provided with an IGBT, a diode and a parallel current limiting component in an intermediate DC circuit between a switching rectifier and an output inverter, and the drive is operated in one of three modes for motoring, regenerating and precharging.
