    L100 Inverter be performed only by qualified personnel. Factory-recommended test procedures included in the instruction manual should be followed. Always disconnect electrical power before working on the unit. CAUTION: a) Class I motor must be connected to protective earth via low resistive path (< 0.1ohm) b) Any motor used must be of a suitable rating.

    Precautions for EMC (Electromagnetic Compatibility) Precautions for EMC (Electromagnetic Compatibility) You are required to satisfy the EMC directive (89/336/EEC) when using an L100 inverter in a European country. To satisfy the EMC directive and to comply with standard, follow the checklist below.

    CAUTION: Be sure not to input a single phase to a three-phase- only type inverter. Otherwise, there is the danger of fire. CAUTION: Be sure not to connect an AC power supply to the output terminals. Otherwise, there is the danger of injury and/or fire.

  • Page 10

    CAUTION: Be sure to install a fuse in the wire for each phase of the main power supply to the inverter. Otherwise, there is the danger of fire. CAUTION: For motor leads, earth leakage breakers and electro- magnetic contactors, be sure to size these components properly (each must have the capacity for rated current and voltage).

    Otherwise, it may cause injury to personnel. WARNING: If the power supply is cut off for a short period of time, the inverter may restart operation after the power supply recovers if the command to operate is active.

    Warnings and Cautions for Troubleshooting and Maintenance WARNING: Wait at least five (5) minutes after turning off the input power supply before performing maintenance or an inspection. Otherwise, there is the danger of electric shock. WARNING: Make sure that only qualified personnel will perform maintenance, inspection, and part replacement.

    Inverter Specifications Label The Hitachi L100 inverters have product labels located on the right side of the housing, as pictured below. Be sure to verify that the specifications on the labels match your power source, motor, and application safety requirements.

    L100 Inverter Specifications Model-specific tables for 200V and 400V class inverters The following three tables are specific to L100 inverters for the 200V and 400V class model groups. The table on page 1–6 gives the general specifications that apply to both voltage class groups.

    Footnotes for the preceding tables and the table on the following page: *1: The protection method conforms to JEM 1030. *2: The applicable motor refers to Hitachi standard 3-phase motor (4-pole).

  • Page 24: Introduction To Variable-frequency Drives

    Introduction to Variable-Frequency Drives The Purpose of Motor Speed Control for Industry Hitachi inverters provide speed control for 3-phase AC induction motors. You connect AC power to the inverter, and connect the inverter to the motor. You’re probably familiar with the way a light dimmer works to vary the power sent to a light bulb, and thus the light intensity.

  • Page 25

    Speed regulation is a measure of the accuracy speed control, given as a percent difference from a fixed value. The L100 delivers speed regulation (no load to full load) within 3% of the (full scale) motor nameplate speed value.

  • Page 26

    The Hitachi inverter is a rugged and reliable device. The intention is for the inverter to assume the role of switching power to the motor during all normal operations. Therefore, this manual instructs you not to switch off power to the inverter while the motor is running (unless it is an emergency stop).

  • Page 27

    See pages 5–2 and 5–5 for more information on the BRD–E2 and BRD–EZ2 braking units. The L100 inverter sends excess motor energy into the resistor in the dynamic braking unit to slow the motor and load. If you have a load that tries to drive the motor continuously for some period of time, that will require a different type of inverter with continuous regenerative capability.

  • Page 28

    FWD and REV commands determine the direction before the motion starts. NOTE: The L100 can move loads in both directions. However, it is not designed for use in servo-type applications that use a bipolar velocity signal which determines direction.

  • Page 29: Frequently Asked Questions

    The term “inverter” is a little confusing, since we also use “drive” and “amplifier” to describe the electronic unit that controls a motor. What does “inverter” mean? Although the L100 inverter is a variable speed drive, can I use it in a fixed-speed application?

  • Page 30

    Why does the manual or other documentation use terminology such as “200V class” instead of naming the actual voltage, such as “230 VAC?” Why is there not a 100V class version of the L100 inverter, so it would work with a USA 115VAC power source, for example? I live in a country where the domestic utility power is 115 VAC.

  • Page 31

    What type of motor is compatible with the Hitachi inverters? How many poles should the motor have? Will I be able to add dynamic (resistive) braking to my Hitachi L100 drive after the initial installation? How will I know if my application will require resistive braking? Several options related to electrical noise suppression are available for the Hitachi inverters.

    State of Inverter at Stop - If you adjust the motor’s speed to zero, the motor will slow to a near stop, and the inverter turns the outputs off.

WARNING: If the power supply is cut off for a short period of time, the inverter may restart operation after the power supply recovers if the command to operate is active. If a restart may pose danger to personnel, so be sure to use a lock-out circuit so that it will not restart after power recovery.
