  • Page 3: Getting Started

    Chapter 1, “Getting Started,” in the L100 Inverter Instruction Manual. Main Features Congratulations on your purchase of an L100-M Series Hitachi inverter! Like the standard L100 Series inverters, this inverter drive features state-of-the-art circuitry and components, exceptionally small footprint, and high performance. The Hitachi L100-M product line includes three additional inverter models to cover motor sizes 1/4, 1/2, and 1 horsepower in 100VAC power input versions.
  • Page 4 Getting Started Inverter Specifications Label The Hitachi L100-M Series 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.
  • Page 5 L100-M Inverter Model-specific tables for 100V class inverters The following table is specific to L100-M Series inverters. Note that “General Specifica- tions” on page 6 apply to all L100-M inverters. Footnotes for both tables follow the table below. Item 100V Class Specifications L100-M invert- CE version —...

  • Page 6: General Specifications

    Footnotes for the preceding table and the table that follows: *1: The protection method conforms to JEM 1030. *2: The applicable motor refers to Hitachi standard 3-phase motor (4-pole). When using other motors, care must be taken to prevent the rated motor current (50/60 Hz) from exceeding the rated output current of the inverter.

  • Page 8: Derating Curves

    Getting Started 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.

The “Power Lines” column applies to the inverter input power, output wires to the motor, the earth ground connection, and any system components such as braking resistors and filters.
  • Page 14 Inverter Mounting and Installation Terminal Dimensions and Torque Specs The terminal screw dimensions for all L100 inverters are listed in table below. This information is useful in sizing spade lug or ring lug connectors for wire terminations. CAUTION: Fasten the screws with the specified fastening torque in the table below. Check for any loosening of screws.

  • Page 15: Configuring Drive Parameters

    This section provides details for L100-M Series configuration corresponding to Chapter 3, “Configuring Drive Parameters,” in the L100 Inverter Instruction Manual. Relative to standard L100 Series inverters, Hitachi L100-M Series inverters have additional parameters and functions, or parameters with a different setting range. These include D_16, F_04, B_12, B_13, B_32, C_01 to C_05, C_70, C_71, C_72, and C_79.

  • Page 21: Operations And Monitoring

    L100-M Inverter Operations and Monitoring This section covers new or modified intelligent terminal functions for L100-M Series inverters, corresponding to Chapter 4, “Operations and Monitoring,” in the L100 Inverter Instruction Manual. The additional functions include Run key routing via [FW] or [RV] terminals, three-wire operation, remote control up and down functions, and force opera- tion from a digital operator (keypad).

  • Page 23 L100-M Inverter Forward Run/Stop and Reverse Run/Stop Commands: When you input the Run command via the terminal [FW], the inverter executes the Forward Run command (high) or Stop command (low). When you input the Run command via the terminal [RV], the inverter executes the Reverse Run command (high) or Stop command (low).
  • Page 24 Operations and Monitoring Three-wire Interface Operation The 3-wire interface is an industry standard motor control interface. This function uses two inputs for momentary contact start/stop control, and a third for selecting forward or reverse direction. To implement the 3-wire interface, assign 20 [STA] (Start), 21 [STP] (Stop), and 22 [F/R] (Forward/Reverse) to three of the intelligent input terminals.
  • Page 25 L100-M Inverter The diagram below shows the use of 3-wire control. STA (Start Motor) is an edge-sensi- tive input; an OFF-to-ON transition gives the Start command. The control of direction is level-sensitive, and the direction may be changed at any time. STP (Stop Motor) is also a level-sensitive input, and the Stop signal has priority over the Start signal.
  • Page 26 Operations and Monitoring Remote Control Up and Down Functions The [UP] [DWN] terminal functions can adjust the output frequency for remote control while the motor is running. The acceleration time and deceleration time used with this function is the same as for normal operation ACC1 and DEC1. The input terminals operate as follows: •...
  • Page 27 L100-M Inverter Force Operation from Digital Operator This function permits a digital operator interface to override the Run command source setting (A_02) when it is configured for a source other than the operator interface. When the [OPE] terminal is ON and the operator interface gives a Run command, the inverter uses the standard output frequency settings to operate the motor.
