L100-M Inverter

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 following 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

Getting Started
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.

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. 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.

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

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 operation from a digital operator (keypad).

Wiring Diagram Conventions
The input wiring diagrams in this section are examples only. Default and non-default
input terminal assignments are noted throughout; your particular assignments may be
different. Input switch wiring for –xMFU2 models will connect the switch common
(return) to +24VDC, as shown below (left). Input switch wiring for –xMFR2 models will
connect the switch common (return) to Logic GND terminal [L], as shown below (right).

addendum.

Waveform Diagram Conventions
The input signal waveform diagrams in this section (and in the L100 manual, Chapter 4)
assume the intelligent inputs are active high type (corresponds to -MFU2 inverter type).
If your inverter is the -MFR2 type, you must invert the ON/OFF logic sense when
observing or interpreting the input waveforms.

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).

Notes:
• When the Forward Run and Reverse Run
commands are active at the same time, the inverter
enters the Stop Mode.
• When a terminal associated with either [FW] or
[RV] function is configured for normally closed,
the motor starts rotation when that terminal is
disconnected or otherwise has no input voltage.

L100-M Series inverters can also use [FW] and [RV] inputs in real time to determine the
direction of rotation for the keypad Run key. This requires setting A_02=02 (keypad
control) and Run Key Routing F_04 = 02 (terminal). The operation is shown below.

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. Use
momentary contact for Start and Stop. Use a selector switch such as SPST for the
Forward/Reverse input. Be sure to set the operation command selection A_02=01 for
input terminal control of motor. If you have a motor control interface that needs logiclevel control (rather than momentary pulse control), use the [FW] and [RV] inputs
instead.

Example (requires input configuration—
see Chapter 3 in L100 Instruction Manual):

Notes:
• The STP logic is inverted. Normally the switch will
be closed, so you open the switch to stop. In this
way, a broken wire causes the motor to stop
automatically (safe design).
• When you configure the inverter for 3-wire interface control, the [FW] and [RV] intelligent terminal
assignments are disabled.
• The [F/R] terminal signal level is evaluated only
when an [STA] pulse occurs.
• You must assign both the [STA] and [STP] intelligent inputs in order for the three-wire function to
work.

• If you do not assign the [F/R] intelligent input terminal, the three-wire operation will be limited to the
forward direction only.

L100-M Inverter
The diagram below shows the use of 3-wire control. STA (Start Motor) is an edge-sensitive 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. Also
remember that STP is an active-low signal.

When both STA and STP signals are ON, the STP signal has priority (motor output will

STA input is still ON.

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:
• Acceleration - When the [UP] contact is turned ON, the output frequency accelerates
from the current value. When it is turned OFF, the output frequency maintains its
current value.
• Deceleration - When the [DWN] contact is turned ON, the output frequency decelerates from the current value. When it is turned OFF, the output frequency maintains its
current value.
In the graph below, the [UP] and [DWN] terminals activate while the Run command
remains ON. The output frequency responds to the [UP] and [DWN] commands.

Notes:
• This feature is available only when the frequency

control. Confirm A_01 is set to 02.
• This function is not available when [JG] is in use.
• The range of output frequency is 0 Hz to the value
in A_04 (maximum frequency setting).
• The Remote Control Up/Down function varies the
inverter speed by directly writing to the F_01
output frequency setting.

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.

Notes:
• When changing the [OPE] state during Run Mode
(inverter is driving the motor), the inverter will stop
the motor before the new [OPE] state takes effect.
• If the [OPE] input turns ON and the digital operator
gives a Run command while the inverter is already
running, the inverter stops the motor. Then the
digital operator can control the motor.

Communication error

Cause(s)
• The RS422/485 serial cable may be disconnected
or have an open wire, short, etc.
• The communication error may be due to the
external device. Check whether the interruption is
for more than 3 seconds before resetting the error.
If so, the watchdog timer in the inverter is timing
out due to no response from the external device.
