L100-M Inverter 3
Getting Started
This section provides specification details for L100-M Series inverters corresponding to
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. The main features are:
• 100V Class inverters
• UL versions, type -MFU2 and -MFR2 (see note below)
• V/f (volts-per-hertz) control algorithm, selectable for either constant or reduced torque
loads
• Convenient keypad for parameter settings
• Three-wire control interface
• Up/Down electronic motorized speed pot function
• Built-in RS-422 communications interface to allow configuration from a PC and for
field bus external modules.
• Sixteen programmable speed levels
• Two-step acceleration and deceleration curves
• PID control adjusts motor speed automatically to maintain a process variable value
NOTE: The -MFU2 and -MFR2 product types have the same features, with the follow-
ing exception: The intelligent inputs on the -MFU2 models are the sinking type (require
a connection to +24VDC to turn ON). The intelligent inputs on the -MFR2 models are
the sourcing type (require a connection to logic GND to turn ON). See “Wiring Diagram
Conventions” on page 21.
The design in Hitachi inverters overcomes many of the traditional trade-offs between
speed, torque and efficiency. The performance characteristics are:
• Output frequency range from 0.5 to 360 Hz
• Continuous operation at 100% torque within a 1:10 speed range (6/60 Hz / 5/50 Hz)
without motor derating

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.
*3: The output voltage decreases as the main supply voltage decreases (except when using the
AVR function). In any case, the output voltage cannot exceed the input power supply
voltage.
*4: To operate the motor beyond 50/60 Hz, consult the motor manufacturer for the maximum
allowable rotation speed.
*5: The braking torque via capacitive feedback is the average deceleration torque at the shortest
deceleration (stopping from 50/60 Hz as indicated). It is not continuous regenerative braking
torque. The average deceleration torque varies with motor loss. This value decreases when
operating beyond 50 Hz. Note that a braking unit is not included in the inverter. If a large
regenerative torque is required, the optional regenerative braking unit should be used.
*6: The frequency command is the maximum frequency at 9.8V for input voltage 0 to 10 VDC,
or at 19.6 mA for input current 4 to 20 mA. If this characteristic is not satisfactory for your
application, contact your Hitachi sales representative.
*7: If operating the inverter in an ambient temperature of 40–50° C, reduce the carrier frequency
to 2.1 kHz, derate the output current by 80%, and remove the top housing cover. Note that
removing the top cover will nullify the NEMA rating for the inverter housing.
*8: The storage temperature refers to the short-term temperature during transport.
*9: Conforms to the test method specified in JIS C0911 (1984). For the model types excluded in
the standard specifications, contact your Hitachi sales representative.
*10:The output voltage of xxxMFU / xxxMFR is 230V.

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. Ambient temperature is
the temperature just outside the inverter housing—such as inside the control cabinet
where the inverter is mounted. A higher ambient temperature decreases (derates) the
inverter’s maximum current output capacity.
Use the following derating curves to help determine the optimal carrier frequency setting
for your inverter, and to find the output current derating. Be sure to use the proper curve
for your particular L100-M inverter model number.

Preparing for Wiring
It is very important to perform the wiring carefully and correctly. Before proceeding,
please study the cation and warning messages below.
WARNING: “Use 60/75°C Cu wire only” or equivalent.
WARNING: “Open Type Equipment.”
WARNING: “A Class 2 circuit wired with Class 1 wire” or equivalent.
WARNING: “Suitable for use on a circuit capable of delivering not more than 5,000
rms symmetrical amperes, 120 V maximum.” For models with suffix M (such as
004MFU2).
HIGH VOLTAGE: Be sure to ground the unit. Otherwise, there is a danger of electric
shock and/or fire.
HIGH VOLTAGE: Wiring work shall be carried out only by qualified personnel. Other-
wise, there is a danger of electric shock and/or fire.
HIGH VOLTAGE: Implement wiring after checking that the power supply is OFF. Oth-
erwise, you may incur electric shock and/or fire.
WARNING: Do not connect wiring to an inverter or operate an inverter that is not
mounted according the instructions given in this manual. Otherwise, there is a danger of
electric shock and/or injury to personnel.

L100-M Inverter 13
Determining Wire and Fuse Sizes
The maximum motor currents in your application determines the recommended wire
size. The following table gives the wire size in AWG. 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. The “Signal Lines” column
applies to any wire connecting to the two green 7 and 8-position connectors just inside
the front panel half-door.
Note 1: Field wiring must be made by a UL-listed and CSA-certified closed-loop
terminal connector sized for the wire gauge involved. Connector must be
fixed by using the crimping tool specified by the connector manufacturer.
Note 2: Be sure to consider the capacity of the circuit breaker to be used.
Note 3: Be sure to use a larger wire gauge if power line length exceeds 66 ft (20m).
Note 4: Use 18 AWG / 0.75 mm2wire for the alarm signal wire ([AL0], [AL1], [AL2]
terminals).
The terminal arrangement below corresponds to all L100-M Series inverter models.

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.
The tables in this section list only these parameters as they apply to L100-M Series
inverters.
“D” Group: Monitoring Functions
L100-M Series inverters add the following to the monitoring functions.
“F” Group: Main Profile Parameters
For parameter F_04, L100-M Series inverters have the additional “02 Terminal” setting.
With F_04=02, the inverters use [FW] and [RV] inputs in real time to determine the
direction of rotation for the keypad Run key. For more information on Run key operation
and interaction with [FW] and [RV] terminals, see page “Forward Run/Stop and Reverse
Run/Stop Commands:” on page 23.

B_32: Reactive current setting – The inverter’s D_02 monitor function displays the
motor current. The display accuracy is normally ±20%, provided that the following
conditions exist:
• A single motor with standard frame size and characteristics is connected
• The inverter’s output frequency is at 50% or higher of the maximum output frequency
• The inverter’s output current is within the rated current
However, it will be necessary to calibrate the display accuracy via B_32 adjustment of
the internal no-load reactive motor current if any of these conditions exist:
• The motor is smaller than the standard maximum recommended for the inverter
• The motor is a two-pole motor type
• Two or more motors are connected in parallel to the inverter (be sure to multiply the
current by the number of motors when setting B_32)
For general purpose motors that have an undetermined internal no-load (reactive) motor
current, use the following table for typical current values. For special motors, consult the
