YASKAWA J1000 Compact AC Drive Series release

New ProductNov 28, 2007

New release of small and simple YASKAWA AC Drive “J1000” series
– Reliability experienced in the small body –

YASKAWA Electric Corporation (President: Koji Toshima) has commercialized YASKAWA AC Drive “J1000” as a new series of small and versatile AC Drives, meeting the needs of the market of AC Drives, small machines which are growing rapidly, and will start the sales from December 21, 2007.
1. Purpose of the commercialization
  Global warming which is caused by the increase in energy consumption has been recognized as a global issue, and ordinary people are also becoming more and more conscious about the countermeasures. People have greater expectations of “versatile AC Drives” in industrial system machinery, too, as energy-saving equipment and the applications has been expanding.
In particular, in the small-sized AC Drive field, a strong demand is growing for miniaturization and cost reduction of AC Drive itself with the demand for the reduction in machinery size.
Against these backgrounds, “J1000” series became commercially available which provides maximum drive more simply and economically than YASKAWA AC Drive “V1000” series released in December 2006, as the first in a new series of next AC Drives.

The commercialization of YASKAWA AC Drive “J1000” series, in which the standard products are RoHS-compliant (the Restriction of Hazardous Substances in Europe) as an environmental measure together with the ultimate miniaturization and user-friendly operations and simplified settings, will meet the growing energy-saving needs.


2. Main features
(1) Fully equipped with user and environmentally-friendly functions
– Compact Design
  Ultra small body and side-by-side installation helps you to design and set up a more compact control panel.
– Easy Operation
  Parameters can be set easily in the setup mode. The verify function makes it easy to check those parameters changed from their default values.
– Environmentally Friendly
  The standard products are compliant with RoHS (EU’s Restriction of Hazardous Substances). Our product adopts the Swing PWM method that suppresses the electromagnetic noise to eliminate harsh noise.
(2) Supports stable operations “Various approaches to Start, Run, and Stop”
-Easy Start Even in Heavy Duty Rating <Start>
  Full-area and fully-automatic torque boost operations generate a high torque, regardless of whether the speed is accelerated / decelerated or constant. Capable of a 100% torque at 1.5 Hz and a 150% torque at 3 Hz under the HD rating.
– Keeps running in the event of a momentary power loss or a change in load or power supply <Run>
  Satisfactory stall prevention and speed search functions act in advance to prevent the AC Drive trip from kicking in and to keep the machine running.
– Full Braking Function <Stop>
  Overexcitation braking enables emergency braking without the use of a braking resistor. Furthermore, the internal braking transistor provides more powerful braking capabilities only by adding a braking resistor.
(3) Functions and services that bring you safety and assurance
– Environmental Tolerance Design
  Various environmentally tolerant products are available to protect the AC Drive against humidity, dust, oil mist, and vibration.
– Hassle-free Maintenance
  Makes for a safe check of capacitors or the fan during the maintenance period via the monitor. Also, the engineering tool DriveWizard Plus* lets you unify parameter management on your PC.
– Interactive customer service
  Feel free to contact our call center for any inquiries and information about our products. Our specialized engineers will respond you politely with their true opinions.

*An interface unit(option) is necessary to use DriveWizard Plus.

(4) A wide variety of variations with more ease of use
  Models that can be connected to a single-phase 100 V commercial power supply are being prepared.*
  EMC filter integrated models are being prepared.
  Variable resistor unit for frequency setting is being prepared (option).
  Remote operation LED operator is being prepared (option).
  – Unit for MEMOBUS communication is being prepared (option).
  * Under development

  We will exhibit YASKAWA AC Drive “J1000” series at SEMICON Japan 2007 (held at the Makuhari Messe from December 5 to 7, 2007) hosted by SEMI JAPAN.
  [Description of the terms]
  1. Normal duty (ND) rating / heavy duty (HD) rating
    Rating corresponding to relatively light-load machines, such as fans and pumps, is called normal duty (ND) rating. In comparison with this, rating corresponding to heavy-load machines, such as conveyors and small-sized elevating devices, is called heavy duty (HD) rating. When an AC Drive has both ratings, an optimum capacity corresponding to each load can be selected.
  2. EU’s RoHS Directive
    Standing for the restriction of the use of certain hazardous substances in electrical and electronic equipment, this directive prohibits electronic equipment sold in Europe from containing specific hazardous substances such as lead. Control devices such as AC Drives are exempt from its regulation as of today, but some countermeasures are desired from the viewpoints of the reduction of environmentally harmful substances.
  3. Swing PWM control systems
    In normal PWM control systems, harsh metallic noises occur when the carrier frequency is low, and electromagnetic noise increases when it is high. Our original SwingPWM system reduces harsh noises by making the carrier frequency variable and not increasing it to make the noises disappear in those at the plant.
