    Inverter Input and Three-phase Power The Hitachi WJ200 Series of inverters includes two sub-groups: the 200V class and the 400V class inverters. The drive described in this manual may be used in either the United States or Europe, although the exact voltage level for commercial power may be slightly different from country to country.

  • Page 43: Frequently Asked Questions

    1−23 Frequently Asked Questions Q. What is the main advantage in using an inverter to drive a motor, compared to alternative solutions? A. An inverter can vary the motor speed with very little loss of efficiency, unlike mechanical or hydraulic speed control solutions. The resulting energy savings usually pays for the inverter in a relatively short time.

  • Page 44

    Q. How many poles should the motor have? A. Hitachi inverters can be configured to operate motors with 2, 4, 6, or 8 poles. The greater the number of the poles, the slower the top motor speed will be, but it will have higher torque at the base speed.

    This is a physics question that may be answered either empirically or through extensive calculations. Q. Several options related to electrical noise suppression are available for the Hitachi inverters. How can I know if my application require any of these options? A.

    2−6 Step-by-Step Basic Installation This section will guide you through the following basic steps of installation: Step Activity Page Choose a mounting location in compliance with the Warnings and Cautions. See NOTE below. Check the mounting location for adequate ventilation Cover the inverter’s ventilation openings to prevent debris from entering.

    2−7 Choosing a Mounting Location Step 1: Study the following caution messages associated with mounting the inverter. This is the time when mistakes are most likely to occur that will result in expensive rework, equipment damage, or personal injury. CAUTION: Be sure to install the unit on flame-resistant material such as steel plate. Otherwise, there is the danger of fire.

    2−8 Ensure Adequate Ventilation Step 2: To summarize the caution messages – you will need to find a solid, non-flammable, vertical surface that is in a relatively clean and dry environment. In order to ensure enough room for air circulation around the inverter to aid in cooling, it is recommended to maintain the specified clearance and the inverter specified in the below diagram.

    Recent developments in power semiconductors have produced transistors capable of handling high voltages and currents, all with high reliability. The saturation voltage has been decreasing, resulting in less heat dissipation. Hitachi inverters use state-of-the-art semiconductors to provide high performance and IGBT Saturation reliability in a compact package.

    B−6 Message Configuration: Query Slave address: • This is a number of 1 to 32 assigned to each inverter (slave). (Only the inverter having the address given as a slave address in the query can receive the query.) • When slave address “0” is specified, the query can be addressed to all inverters simultaneously.

    D−2 CE-EMC Installation Guidelines You are required to satisfy the EMC directive (2004/108/EC) when using an WJ200 inverter in an EU country. To satisfy the EMC directive and to comply with standard, you need to use a dedicated EMC filter suitable for each model, and follow the guidelines in this section. Following table shows the compliance condition for reference.

    D−3 3. As user you must ensure that the HF (high frequency) impedance between adjustable frequency inverter, filter, and ground is as small as possible. • Ensure that the connections are metallic and have the largest possible contact areas (zinc-plated mounting plates). 4.

  • Page 415

    D−4 8. Follow safety measures in the filter installation. • If using external EMC filter, ensure that the ground terminal (PE) of the filter is properly connected to the ground terminal of the adjustable frequency inverter. An HF ground connection via metal contact between the housings of the filter and the adjustable frequency inverter, or solely via cable shield, is not permitted as a protective conductor connection.

    D−5 Installation for WJ200 series (example of SFE models) Model LFx (3-ph. 200V class) and HFx (3-ph. 400V class) are the same concept for the installation. Power supply 1-ph. 200V Metal plate (earth) The filter is a footprint type, so it is located between the inverter and the metal plate.

    D−6 Hitachi EMC Recommendations WARNING: This equipment should be installed, adjusted, and serviced by qualified personal familiar with construction and operation of the equipment and the hazards involved. Failure to observe this precaution could result in bodily injury. Use the following checklist to ensure the inverter is within proper operating ranges and conditions.

    E−2 Introduction The Gate Suppress function can be utilized to perform a safe stop according to the EN60204-1, stop category 0 (Uncontrolled stop by power removal). It is designed to meet the requirements of the ISO13849-1, PL=d only in a system in which EDM signal is monitored by an “external device monitor”.

    E−3 Components to be combined Followings are the example of the safety devices to be combined. Series Model Norms to comply reference certificate GS9A ISO13849-2 cat4, SIL3 06.06.2007 G9SX GS226-T15-RC IEC61508 SIL1-3 04.11.2004 NE1A SCPU01-V1 IEC61508 SIL3 27.09.2006 In combination with the safety device complying with the class complying PL=d, PL=d of the inverter is to be achieved.
