Over 80 Years of Experience in Variable Speed DrivesHitachi, Ltd. (hereinafter “Hitachi”) has pulled drive system control technologies of the iron & steel industry in the world. The Hitachi’s fi rst product 7,000 HP Ward Leonard drives for rolling mills were delivered in 1933. During a recent 20-year period, Hitachi has focused on higher capacity by progress of power semiconductor and series/parallel connections technology in order to save energy, address environment and realize high-end clean energy power, low-carbon society. Hitachi will continue to provide higher added value solutions for customers based on increased productivity, quality and maintainability through ALD(Analysis Lead Design) technologies, 3D CAD and CAE with cutting-edge IT.
Realize longer operating life cycle with IGBTHitachi has applied general-purpose IGBT, more reliable as a global standard power device, for current variable frequency drive systems in various industrial worlds such as steel, water/sewerage, chemical, transportation, and electric power fi elds since 1992. Hitachi’s unique design achieves more stable quality, more steady supply, higher reliability, more robust hardware and wider capacity in three fundamental ways:1) They have been verifi ed through actual systems for worldwide steel plants. 2) Reducing IGBT breakdown risk and its damage range by balance & monitor.3) The capacity can be managed by multiple connections technologies.In fact, IGBT becomes best suited to Hitachi’s drive system.

ALD TechnologiesHitachi has developed HIVECTOL-VSI series drive products through ALD technology. The ALD technology can elucidate a phenomenon with both simulation and experiment, and can establish prior prediction technique that can be horizontally available. A phenomenon is impressed by an experiment and in analysis, and analytical results are guaranteed by validation experiments. In other words, fusion of the analysis and the experiment is required.
Less Footprints by Structural Design
It enables comprehensive optimization in packaging density of drive system through the use of 3D simulation in cubicles with structural model. Therefore, the footprints of the drive system panel is optimized to be the minimum.
Improved Heat Dissipation Performance
It enables downsizing drive system through 3D thermal analysis simulation in cubicles with structural model.
Minimize Commissioning Period on Site
Hitachi has striven to minimize commissioning period for drive system by high-precision real-time simulator. It enables dummy operation test of drive system on par with site conditions through the following real-time simulation model including main circuits of drive motor and driven mechanical load.

Easy Analysis and Diagnostics
It’s very easy for users to watch various kinds of helpful information such as operation status and alarm information, analyze and diagnose fault condition through touch panel operation on a large LCD .
Easy Maintenance
Maintenance software tool helps maintain drive system easier. It’s available on a console connected with drive system or human-machine interface (HMI) consoles for operating plant control. Data communication between drive system and HMI console is done by plant controller connected with drive system via Hitachi’s Drive network (DRV-NET). The tool functions are as follows:
Drive Network for Inverter / Converter Drives
In steel plant systems, one facility uses more than several dozen motors controlled by each drive systems. Their tuning and maintenance poses considerable diffi culties. Hitachi ltd. has made this work easier by developing a drive network that extends the protocols used on conventional fi eld network cabling between drives and controllers, and by providing support for this new network in its products. in the network, data communication with drives is carried on existing cabling but operates in a way that doesn’t interfere with control functions. It can be used to access remotely located drives via the controller from any HMI consoles connected to the control system, supporting operations such as retrieving detailed information, uploading failure data, resetting, specifying control parameters, and loading programs.
