  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.

  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).

• 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.

  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. 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.

  Connecting to PLCs and Other Devices Connecting to PLCs and Other Devices Hitachi inverters (drives) are useful in many types of applications. During installation, the inverter keypad (or other programming device) will facilitate the initial configura- tion. After installation, the inverter will generally receive its control commands through the control logic connector or serial interface from another controlling device.

  Dead band may or may not be desirable; it depends on the needs of the application. For Hitachi inverters, “digital operator panel” (DOP) refers first to the operator keypad on the front panel of the inverter. It also includes hand-held remote keypads, which connect to the inverter via a cable.

  A device that electronically changes DC to AC current through a alternating process of switching the input to the output, inverted and non-inverted. A variable speed drive such as the Hitachi L100 is also called an inverter, since it contains three inverter circuits to generate 3-phase output to the motor.

  The ability of a motor drive to store preset discrete speed levels for the motor, and control motor speed according to the currently selected speed preset. The Hitachi inverters have 16 preset speeds. In motor terminology, motor load consists of the inertia of the physical mass that is moved by the motor and the related friction from guiding mechanisms.
