  • Page 31 1–12 L100 Inverter Specifications Derating Curves The maximum available inverter current output is limited by the carrier frequency and ambient temperature. The carrier frequency is the inverter’s internal power switching frequency, settable from 0.5 kHz to 16 kHz. Choosing a higher carrier frequency tends to decrease audible noise, but it also increases the internal heating of the inverter, thus decreasing (derating) the maximum current output capability.

  • Page 38 Inverter Input and Three-Phase Power The Hitachi L100 Series of inverters includes two sub-groups: the 200V class and the 400V class inverters. The drives 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 39 The Hitachi inverter is a rugged and reliable device. The intention is for the inverter to assume the role of controlling power to the motor during all normal operations. There- fore, this manual instructs you not to switch off power to the inverter while the motor is running (unless it is an emergency stop).
  • Page 40 For loads that continuously overhaul the motor for extended periods of time, the L100 may not be suitable (contact your Hitachi distributor). The inverter parameters include acceleration and deceleration, which you can set to match the needs of the application.

  • Page 42: Frequently Asked Questions

    1–23 L100 Inverter Frequently Asked Questions What is the main advantage in using an inverter to drive a motor, compared to alternative solutions? 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 43 The greater the number of poles, the slower the top motor speed will be, but it will have higher torque at the base speed. Will I be able to add dynamic (resistive) braking to my Hitachi L100 drive after the initial installation? Yes.
  • Page 44 Several options related to electrical noise suppression are available for the Hitachi inverters. How can I know if my application will require any of these options? The purpose of these noise filters is to reduce the inverter electrical noise so the operation of nearby electrical devices is not affected.

    4–14 Using Intelligent Input Terminals Free-run Stop When the terminal [FRS] is turned ON, the inverter stops the output and the motor enters the free-run state (coasting). If terminal [FRS] is turned OFF, the output resumes sending power to the motor if the Run command is still active. The free-run stop feature works with other parameters to provide flexibility in stopping and starting motor rotation.

  • Page 126: External Trip

    4–15 L100 Inverter External Trip When the terminal [EXT] is turned ON, the inverter enters the trip state, indicates error code E12, and stops the output.

    C–2 CE–EMC Installation Guidelines CE–EMC Installation Guidelines You are required to satisfy the EMC directive (89/336/EEC) when using an L100 inverter in an EU country. To satisfy the EMC directive and to comply with standard, follow the guidelines in this section. 1.
  • Page 185 C–3 L100 Inverter 4. Take measures to minimize interference that is frequently coupled in through installa- tion cables. • Separate interfering cables with 0.25m minimum from cables susceptible to inter- ference. A particularly critical point is laying parallel cables over longer distances.
