HAZARDOUS HIGH VOLTAGE
Motor control equipment or electronic controllers are connected to hazardous line
voltages. When servicing drives and electronic controllers there migh exist exposed
components with cases ore protrusions at or above line potential. Extreme care should
be taken to protect against shock.
For these reasons, the following safety guidelines should be observed:
Stand on an insulating pad and make it a habit to use only one hand when checking
components. Disconnect power before checking controllers or performing
maintenance. Be sure that equipment is grounded properly. Wear safety glasses
whenever working on an electronic controller or rotating electrical equipment.
WARNING This equipment should be installed, adjusted and serviced only by qualified electrical
maintenace personell familiar with the construction and operation of the equipment
and the hazards involved. Failure to observe this precaution could result in bodily
injury.
WARNING The user is responsible that all driven machinery, drive train mechanism not supplied
by Hitachi, Ltd., and process line material are capable of safe operation at an applied
frequency of 150% of the maximum selected frequency range to the AC motor. Failure
to do so can result in destruction of equipment and injury to personnell should a single
point failure occur.

connecting the motor, contact breaker, filter etc.) must be inaccessible in end
installation.
All of the above instructions, together with any other requirements, reccommendations,
and safety messages highlighted in this manual must be strictly complied with.
NOTES ON EMC (ELECTRO MAGNETICAL COMPATIBILITY)
WARNING This equipment should be installed, adjusted and serviced by qualified personnell
familiar with construction and operation of the equipment and the hazards
involved. Failure to observe this precaution could result in bodily injury.
When using L100 series inverters in EU countries, the EMC directive 89/336/EEC must be observed. To
satisfy the EMC directive and to comply with the standard, the following provisions should be obeyed:
A) Environmental conditions for the inverter:
• Ambient temperature: -10°C to 40°C.
• Relative Humidity: 20% to 90% (no dew condensation)
• Vibrations: max. 5,9m/s2 (0.6 g) at 10–55Hz.
• Location: 1000 meter or less altitude, indoors (no corrosive gas or dust).
B) The power supply to the L100 inverter must conform to the conditions stated below. If one of the
conditions mentioned is not satisfied then an appropriate L100 AC reactor will have to be installed.
• Voltage fluctuation +/-10% or less
• Voltage unbalance +/-3% or less
• Frequency variation +/-4% or less
C) Wiring
• Shielded wiring (screened cable) is required for motor wiring, and total length has to be kept to less
than 50m. When using motor cables longer than 50m L100 motor filters should be installed. Directions
for installing filters can be found in the L100 installation manual.
• Seperate the mains circuit wiring from the wiring used for signals or process circuit. Please refer to
the L100 installation manual.
D) Installation
• For L100 series inverters, the filters described hereafter have to be used and the installation notes
have to be observed.
If installed according to the following directions, the frequency inverters comply with the following standards:
Emmissions:
EN 61800-3 (EN 55011 group 1, class B)
Immunity:
EN 61800-3, industrial environments
For the best possible damping of interference, special line filters have been developed which guarantee you
easy assembly and installation along with the necessary electrical reliability. However, effective EMC is only
ensured if the suitable filter is selected for the particular drive and installed in accordance with these EMC
recommendations. Please choose the appropriate filter using the table below:

The amount of line-conducted interference also increases as motor cable length increases. Adherence to the
interference limits for line-conducted interference is guaranteed on following way:
• If maximum motor cable length is 10 m at maximum elementary frequency:
Class „B“.
• If maximum motor cable length is 20 m at elementary frequency 5 kHz:
Class „B“.
• If maximum motor cable length is 50 m at maximum elementary frequency:
Class „A“.
Observe the following provisions for an electromagnetically compatible setup of your drive system:
1. As user you must ensure that the HF impedance between frequency inverter, filter and ground is as small
as possible.
• See to it that the connections are metallic and have the largest possible areas (zink-plated mounting
plates)
2. Conductor loops act like antennas, especially when they encompass large areas. Consequently:
• Avoid unnecessary conductor loops
• Avoid parallel arrangement of „clean“ and interference-prone conductors
3. Lay the motor cable and all analog and digital contol lines shielded.
• You should allow the effective shield area of these lines to remain as large as possible; i.e., do not
move the shield further away than absolutely necessary.
• With compact systems, if for example the frequency inverter is communicating with the steering unit,
in the same control cabinet connected at the same PE-potential, the screen of control lines should be
put on, on both sides with PE. With branch systems, if for example the communicating steering unit is
not in the same control cabinet and there is a distance between the systems, we recommend to put on
the screen of control lines only on the side of the frequency inverter. If it is possible, direct in the cable
entry section of the steering unit. The screen of Motor cabels always must be put on, on both sides with
PE.
• The large area contact between shield and PE-potential you can realise with a metal PG screw
connection or a metallic mounting clip.
• Use only copper mesh cable (CY) with 85% coverage
• The shielding should not be interrupted at any point in the cable. If the use of reactors, contactors,
terminals or safety switches in the motor output is necessary, the unshielded section should be kept as
small as possible.
• Some motors have a rubber gasket between terminal box and motor housing. Very often, the terminal
boxes, and particularly the threads for the metal PG screw connections, are painted. Make sure there is
always a good metallic connection between the shielding of the motor cable, the metal PG screw
connection, the terminal box and the motor housing, and carefully remove this paint if necessary.
4. Very frequently, interference is coupled in through installation cables. This influence you can minimize:
• Lay interfering cables separately, a minimum of 0.25 m from cables susceptible to interference.
• A particularly critical point is laying cables parallel over larger distances. If two cables intersect, the
interference is smallest if they intersect at an angle of 90°. Cables susceptible to interference should
therefore only intersect motor cables, intermediate circuit cables, or the wiring of a rheostat at right
angles and never be laid parallel to them over larger distances.
5. The distance between an interference source and an interference sink (interference-threatened device)
essentially determines the effects of the emitted interference on the interference sink.
• You should use only interference-free devices and maintain a minimum distance of 0.25 m from the
drive.
6. Safety measures
• Ensure that the protective conductor terminal (PE) of the filter is properly connected with the protective
conductor terminal of the frequency inverter. An HF ground connection via metal contact between the
housings of the filter and the frequency inverter, or solely via cable shield, is not permitted as
protective conductor connection. The filter must be solidly and permanently connected with the ground
potential so as to preclude the danger of electric shock upon touching the filter if a fault occurs. You
can achieve this by connecting it with a grounding conductor of at least 10 mm² or connecting a second
grounding conductor, connected with a separate grounding terminal, parallel to the protective
conductor (the cross section of each single protective conductor terminal must be designed for the
required nominal load).

1) “Worst case” states the leakage current for three-phase filters in the worst of cases. That means one phase is live and two
phases of the feed-line lead-in are interrupted. These maximum values are based on an operating voltage of 460 V (ph./ph.).
2) The normal leakage current for three-phase filters is stated. This means the filter is operating on 460 V (ph./.ph.). The
stated values are adhered to up to a neutral voltage of 5V to ground caused by line unbalance.

Chapter 1 – Safety precautions
Installation
The following safety precautions are to be observed when installing the frequency inverter:
CAUTION
Be sure to install the inverter on flame resistant material such as metal. Otherwise,
there is a danger of fire.
CAUTION
Be shure not to place anything inflammable in the vicinity. Otherwise, there is a
danger of fire.
CAUTION
Be sure not to let foreign matter (such as cut wire refuse, spatter from welding, iron
refuse, wires, dust etc.) enter the inverter. Otherwise, there is a danger of fire.
CAUTION
Install the inverter in a room which is not exposed to direct sunlight and is well
ventilated. Avoid environments which tend to be high in temperature, high in
humidity or which have dew condensation, as well as places with dust, corrosive
gas, explosive or inflammable gas, grinding-fluid mist, salt damage etc. Otherwise,
there is a danger of fire.
CAUTION
The wall surface on which the inverter is mounted must be of a nonflammable
material, such as a steel plate.
Wiring
WARNING The inverter has to be grounded properly. Otherwise, there is a danger of fire.
WARNING Wiring work must only be carried out when the power supply is off. Otherwise,
there is a danger of electric shock and/or fire.
WARNING Before carrying out the wiring work, the inverter has to be mounted properly.
Otherwise, there is a danger of electric shock or injury.
CAUTION
Make shure that the input voltage is as follows (please also refer to chapter 11):
Single/three phase: 200~240V, 50/60Hz (models up to 2,2kW)
Three phase: 200~240V, 50/60Hz
Three phase: 380~460V, 50/60Hz
CAUTION
Don´t connect AC power supply to the inverter output terminals U, V, and W.
Otherwise, there is a danger of injury and/or fire.

Remarks for using earth leakage circuit breakers in the mains supply:
Frequency inverters with CE-filters (RFI-filter) and screened motor cables have a
higher leakage current against earth. Especially in the moment of switching this can
1-1
Chapter 1 – Safety precautions
cause unintentional triggering of earth leakage circuit breakers. Because of the rectifier
on the input side of the inverter there is the possibility to stall the switch-off function
through amounts of DC current. For these reasons, the following items should be
observed:
Only pulse current sensitive earth leakage circuit breakers which have a short term
delay and a higher trigger current (500mA) should be used. Other components should
be secured with separate earth leakage circuit breakers. Earth leakage circuit breakers
in front of an inverter´s rectifier are not an absolute protection against direct touching.
CAUTION
Each phase of the power supply has to be provided with a fuse. Otherwise, there is a
danger of fire.
Control and operation
WARNING Be sure to turn on the input power supply only after closing the front case. While
being energized, don´t open the front case. Otherwise, there is a danger of electric
shock.
WARNING Never operate the switches with wet hands. Otherwise, there is a danger of electric
shock.
WARNING If the retry mode is selected, the inverter may suddenly restart during a stop which
was caused by a trip. In such a case, be sure not to approach the machine. Provisions
have to be taken that the driven motor or machine does not endanger personnell even
in the case of a sudden restart. Otherwise, there is a danger of injury.
WARNING Even if the power supply is cut off for a short period of time, the inverter may restart
operation after the power supply has recovered if the operation command is given. If
this may incur danger to personnell, provisions have to be made in order to prevent a
restart after power recovery. Otherwise, there is a danger of injury.
WARNING The STOP key is effective only if the corresponding parameters have been set.
Otherwise, there is a danger of injury.
WARNING If a reset is carried out following a trip condition the motor will restart if the
operation command has been given. Be sure to acknowledge this trip condition with
a reset only after confirming that no operation command is active. Otherwise, there
is a danger of injury.
WARNING When the power to the inverter is turned on while the operation command is active
the motor starts immediately. So before turning power supply on be sure to confirm
that no operation command is active.
WARNING If the inverter has been configured for the stop command not to be given using the
STOP key, pressing the STOP key does not stop the motor. In this case a separate
emergency stop switch is necessary.
CAUTION
Operate the motor and machine connected to the inverter only within the
manufacturer´s speed specifications. Otherwise, there is a danger of injury.
CAUTION
If a motor is to be operated at a frequency higher than the standard setting value of
50 or 60Hz, be sure to check the allowable speed of the motor and the machine
with each manufacturer, and operate them only after getting their consent.
CAUTION
Check the following during and after the test run. Otherwise, there is a danger of
machine breakage:
Was the short cut bar between terminals +1 and + removed by mistake?
Was the running direction of the motor correct?
Was the inverter tripped during acceleration or deceleration?
Were the indications of the rpm and the frequency meter correct?
Were there any abnormal motor vibrations or noise?

Chapter 1 – Safety precautions
Maintenance and inspection
WARNING Before carrying out maintenance and inspection wait for at least five minutes after
having turned off the input power supply. Otherwise, there is a danger of electric
shock.
WARNING When removing connectors (e.g. from fans and printed circuit boards) never pull the
attached wires. Otherwise, there is a danger of fire due to wire breakage and/or
injury.
Others
CAUTION
Withstand voltage tests and insulation resistance tests (megger tests) are executed
before the units are shipped, so that there is no need to conduct these tests before
operation.
CAUTION
Do not attach or remove wiring or connectors when power is applied. Also, do not
check signals (e.g. using a multimeter) during operation.
CAUTION
Never stop motor operation by switching off the electromagnetic contactors on the
primary or secondary side of the inverter.

When there has been an instantaneous power failure, and if an operation instruction
has been given, then the inverter may restart operation after the power failure has
ended. If there is a possibibility that such an occurrence may harm humans, then install
an electromagnetic contactor on the primary (power supply) side of the inverter, so
that the circuit does not allow automatic restarting after the power supply has
recoverd. If the optional remote operator is used and the retry function has been
selected, this will also cause automatic restarting when an operation instruction has
been input, so please be careful.
CAUTION
Do not insert leading power factor capacitors or surge absorbers between the output
terminals of the inverter and the motor.

PROTECTION AGAINST NOISE INTERFERENCE FROM THE INVERTER
L100 series inverters use many semiconductor switching elements such as transistors
and IGBTs. For this reason, a radio set or measuring instrument located near the
inverter is susceptible to noise interference. To protect the instruments from erreneous
operation due to noise interference produced by the inverter, they should be installed

current flows on the power supply side, sometimes destroying the converter module:
A) The unbalance factor of the power supply is 3% or higher.
B) The power supply capacity is set at least ten times greater than the inverter
capacity (i.e. 500kVA or more)
C) When abrupt power supply changes are to be expected. Some examples:
1) Several inverters are interconnected using a short bus to the same power
supply.
2) A thyristor converter and an inverter are interconnected using a short bus.
3) An installed power factor compensating device is connected or disconnected.
In the cases mentioned above we recommend installing an AC reactor of 3% voltage
drop at rated current with respect to the supply voltage on the power supply side.
CAUTION
When an EEPROM error occurs (trip E 08) all parameter values have to be checked
for correctness (especially the RS input).
CAUTION
When the intelligent digital inputs FW or RV are configured as normally closed
contact (standard setting is normally open), then the inverter starts automatically. Do
not configure these inputs as normally closed inputs unless absolutely necessary.
GENERAL NOTICE
In all the illustrations and figures in this manual, covers and safety devices are
occasionally omitted in order to better describe the details. When the inverter is
operated make shure that all the covers and safety devices are placed in their correct
positions.

Chapter 4 – Installation
Chapter 4 – Installation
The inverter must be mounted vertically on a non-flammable wall in order to prevent from overheating and
fire. The minimum clearances to the surrounding walls shown in the figure below must be complied with to
ensure a good ventilation. Foreign matter (especially conductive objects) must nut be dropped into the
inverter since they not only cause malfunction and damage but may also lead to electrical and fire hazards.
Cover all ventilation holes on the inverter during installation so that no foreign objects can enter the inverter.
Be sure to remove those covers from the inverter before you put the inverter to work.

Wall or mounting surface
approx. 8cm
approx. 10cm

The inverter must be installed vertically
(do not install it on the floor or horizontally)
The mounting base must be a nonflammable material (e.g. metal)
The minimum clearances to the surrounding walls shown in the figure are only meant for reference. A more
compact installation (back to back) may well be possible and should be discussed with Hitachi. Please always
leave enough room for the key cover to be opened without problems in order to connect wires to the control
terminals.
The ambient temperature should be in the range of -10°C to 50°C. At a temperature of 40~50°C the carrier
frequency has to be reduced to 2kHz, the output current must be kept below 80% of the rated current, and the
top cover (see figure below) has to be removed. Higher ambient temperature causes shorter inverter life. So if
there is hot equipment in the vicinity of the inverter, keep it away from the inverter as far as possible.
If the inverter is to be installed in a cabinet, ambient temperature is considered to be the temperature
prevailing withing this cabinet. Fans have to be provided if necessary so that ambient temperature remains
within the limits specified above.
For safety reasons the digital operator must be closed and not be opened during inverter operation. The end
application must be in accordance with the BS EN 60204-1 standard.

CAUTION
Fasten the screws with the specified fastening torque so that they will not loosen
unintentionally. Check all terminals for loose screws. Otherwise there is a danger of
fire.
CAUTION
Remarks for using earth leakage circuit breakers in the mains supply
Frequency inverters with CE-filters (RFI-filter) and screened motor cables have a
higher leakage current against earth. Especially in the moment of switching this can
cause unintentional triggering of earth leakage circuit breakers. Because of the rectifier
on the input side of the inverter there is the possibility to stall the switch-off function
through amounts of DC current. For these reasons, the following items should be
observed:
Only pulse current sensitive earth leakage circuit breakers which have a short term
delay and a higher trigger current (500mA) should be used. Other components should
be secured with separate earth leakage circuit breakers. Earth leakage circuit breakers
in front of an inverter´s rectifier are not an absolute protection against direct touching.
CAUTION
Each phase of the power supply has to be provided with a fuse. Otherwise, there is a
danger of fire.
CAUTION
As for motor leads, earth leakage breakers, and electromagnetic contactors, be sure to
use the ones that have the correct rating. Otherwise, there is a danger of fire.
CAUTION
Make sure that the mains supply leads are reliably fixed.
Wiring the power supply and motor
In order to connect cables to the power supply or alarm terminals the digital operator has to be opened. For
this, first of all the corresponding screw has to be loosened. The location of the terminals is depicted in the

When connecting cables, the following details have to be considered:
1) Power supply cables must only be connected to the terminals L1, L2, and L3/N.
2) Do not connect any cables to the non-designated terminals in the upper terminal row (refer to figure
above) as these terminals are reserved for L100 internal purposes.
3) If more than one motor is to be driven by a single inverter, thermal relays have to be provided for each
motor.

4) The leads from the power supply must be connected to the mains circuit terminals as follows:
Connect single phase power supply (50/60Hz) to terminals L1, L3/N.
Connect three phase power supply (50/60Hz) to terminals L1, L2, L3/N.
5) Don´t remove the short bar between the terminals +1 and +.

General remarks
When connecting cables, the following items must be observed:
-
When changing the power supply of the motor between the inverter and commercial power line, be sure
to install mechanically interlocked switches (S1 and S2) as shown in the figure below:

-
Install an earth leakage breaker at the input of the inverter. Select an earth leakage breaker which has a
short term delay and a higher trigger current.
When the cable between the inverter and the motor is more than 10 meters long, the thermal relay may
malfunction due to high-frequency waves. To prevent this, install an AC reactor on the output side of the
inverter or use a current sensor rather than a thermal relay.
-
In case a relay is connected to the digital output terminals 11 or 12 be sure to install a surge absorbing
diode in parallel to the relay. Otherwise the surge voltage created when the relay goes on or off may
damage the output circuit.
-
Be sure that the specified grounding is carried out. Separate the inverter´s grounding pole from those of
other heavy electric machinery and avoid using common grounding poles when multiple inverters are
employed.

-
Use relays which are capable of reliably switching at a voltage of 24VDC and a current of 3mA.
-
Install the mains circuit cables at a safe distance from the control circuit cables. If the mains circuit
cables and the control circuit cables have to cross each other, this should be done at an angle of 90
degrees because interference can be minimized in this case.

relays
This part reduces noise generated at the output of the
inverter (this type of filter supplies an almost perfect
sine shaped output voltage between phase-pase and
phase-PE).
Motors that are driven by an inverter are to a larger
extent subject to voltage fluctuations than motors directly
driven (without inverter) by power lines. An AC reactor
installed between inverter output and motor smoothens
motor run and so reduces torque ripple. When the cable
between the inverter and the motor is too long, this part
also forces the voltage dv/dt to be limited and so protects
the isolation of the motor.
Note: Usage of an EMI filter (e.g. one from the FPFL100 series) is
necessary for the European EMC directive, for the Australian C-TICK
and others. In comparison, the other parts mentioned in the table above
are not intended for this special use.

Before starting operation
Prior to the test run, the following items should be checked:
1) Make sure that the power lines (input power supply terminals L1(L1), L2, and L3(N)) and output
terminals (U(T1), V(T2) und W(T3)) are connected correctly.
2) Make sure that there are no mistakes in the signal line connections.
3) The grounding terminal must be grounded.
4) Terminals other than those marked as grounding terminals must not be grounded.
5) The inverter must be installed vertically on a non-flammable mounting surface (e.g. steel).
6) Remove any residue from wiring work like stray pieces of wire and others. Also, make sure that no tolls
are left behind.
7) Make shure that the wires connected to the output terminals are not short-circuited or grounded.
8) All the terminal screws must be sufficiently tightened.
9) The configurable maximum output frequency parameter must be chosen in accordance with the
maximum frequency of the connected motor and machine.
10) Do not operate the inverter with the front case opened. Make sure the front case is completely closed and
locked with the screw.
Do not carry out any withstand voltage tests because the inverter has a surge absorber between the mains
circuit terminals and the ground.

Chapter 6 – General operation notes
In order to test the inverter, follow the procedure described below:
1) Turn on power supply to the inverter. The power LED on the digital operator will light up.
2) Set function A 02 to 02.
3) Set function A 01 to 00. Now the inverter can be operated using the built in potentiometer which is
indicated by the lit lamp above the potentiometer.
4) After pressing the RUN key the motor starts to run and the the RUN lamp lights up.
5) The actual frequency can be monitored using function d 01.
6) You can stop the test run by pressing the STOP key.
CAUTION
After the test run has been completed, check the following items to ensure that the
motor will not be damaged:
Was the direction of the motor run correct? Was there any trip condition during
acceleration or deceleration? Were there any unusual motor sounds or vibrations?
When a trip occured during the test run due to overcurrent or overvoltage, increase
acceleration or deceleration time.

FM terminal
Terminal function
This terminal is used for connecting an analog voltmeter or a digital frequency meter and thus to monitor and
display output frequency. Alternatively, motor current can be monitored instead (when output current is
selected the FM terminal can only supply an analog signal).
1) Frequency display using analog output signal
The analog output signal is a pulse train whose period remains constant. The width of the pulses ist
proportional to the actual output frequency (0 to 10V represent 0Hz to maximum frequency):

The signal frequency equals the actual output frequency multiplied by the factor configured under b 86.
3) Motor current display using analog output signal
This signal is identical to the one described under 1). The width of the pulses is proportional to the actual
motor current. The maximum voltage of 10V is reached when the motor current is two times the inverter
rated current. The signal accuracy is +/-20%. The connection to a meter is described under 1). A moving
iron type amperemeter should be used.

2) When an analog output signal is used (frequency or current), the signal can be adjusted to the special
meter used by specifying a factor under b 81.
3) When the digital output signal (frequency only) is selected, the output signal can be adjusted to the
special meter used by specifying a factor under b 86.

Chapter 7 – Control circuit terminal functions
Terminals 1 - 5 (programmable digital inputs)
General notes
Several functions can be assigned to the terminals 1 through 5. Depending on the application these terminals
can be configured to be forward (FW) or reverse run (RV) inputs, multistage speed setting inputs (CF1-CF4),
reset input (RS), and so on. The terminal function configuration of inputs 1 - 5 is done using C 01 – C 05,
i.e. C 01 is used to set the function of digital input 1, C 02 is used to set the function of digital input 2, etc.
However, two inputs can not be assigned to an identical function at the same time.
The programmable digital inputs 1 - 5 are factory set as normally open contacts. So when a terminal’s
function is to be activated, the digital input configured for this function has to be closed (i.e. the input
terminal must be connected to terminal P24). Likewise, deactivating of an input means opening this input.
Alternatively, the digital inputs can also be configured as normally closed contacts. To do this, the parameter
01 must be configured under functions C 11 – C 15 (corresponding to digital input 1 - 5). But there is an
exception for inputs configured as reset input (RS) or thermistor input (PTC). Those inputs can only be
configured as normally open contacts.

Terminal function
Using the digital inputs configured as CF1 – CF4 one of up to 16 freely selectable frequencies (including the

below). It is not necessary to use all four multistage speed setting terminals at the same time. If you need for
example only up to eight different frequencies it is sufficient to configure only CF1 – CF3; if only up to four
different frequencies are needed only 2 multistage speed setting terminals have to be configured.

Configure one or more of the digital inputs 1 – 5 as CF1 – CF4 input by entering one or more parameters
under C 01 – C 05 (parameter setting range is 02 – 05).
Following this, the multistage frequencies can be programmed by one of two ways:
A) Enter the multistage frequencies under A 21 – A 35.
B) Activate those multistage speed inputs that are necessary for the desired frequency to be configured
(refer to table above) and enter the desired frequency under F 01 (note that the motor must be stopped
first e.g. using the STOP key or deactivating the FW input). The entered frequency value must be stored
using the STR key.
Remarks
• If you want one ore more of the multistage frequencies to be greater than 50Hz the maximum frequency
has to be raised first using A 04.
• A multistage speed setting of 0 (inputs CF1 – CF4 are all deactivated) corresponds to the frequency set
value. This set value can be configured either using the built-in potentiometer, the terminals O
respectively OI, or by configuring F 01 and A 20.

already been set to this value.
2) Configure one of the digital inputs 1 – 5 as AT input by entering the parameter 16 under C 01 – C 05.

Remarks
• When a running command is issued within 3 seconds after turning on the power supply with the USP
function being active, the inverter will enter the USP condition and display the trip E 13 mentioned
above. Consequentely, if the USP function is to be used wait at least 3 seconds before sending a running

Remarks
• The STOP key on the digital operator functions as RESET key when a trip condition has occured. So in
this case it can be used for resetting the inverter instead of the RS input.
• If the RS input is held active for more than 4 seconds this may produce a false trip.
• The RS input is always a normally open contact and can not be configured a normally closed contact.

Terminals 11, 12 (programmable digital outputs)
General notes
The programmable digital outputs 11 and 12 are transistor outputs with open collector (refer to the figure
below) which can be used to connect relays. Various functions can be assigned to these two outputs
according to user demands. Among these functions are signalling when a predefined frequency value is
reached, or when a trip occurs.
11, 12
CM2
Transistor output
27VDC, 50mA max.
24V
The programming of the desired terminal function for each of the two digital outputs 11 and 12 is carried out
using C 21 and C 22, i.e. C 21 is used to set the function of digital output 11, and C 22 is used to set the
function of digital output 12.
The programmable digital outputs are factory preconfigured as normally closed contacts. So if the configured
function of an output terminal is to be activated, the corresponding output will be opened. Deactivation of an
output terminal means that the output is closed.
The digital outputs can alternatively be programmed as normally open contacts. To do this, enter a 00 under
C 32 and C 33 (corresponding to digital output 11 and 12).

provide for a certain amount of hysteresis during switching on and off, the FA1 and FA2 signals are activated
0.5Hz before the current frequency reaches the set value or the frequency set under C 42, respectively. The

1) If a programmable digital output is to be configured with FA2 output function, first of all a frequency
has to be set using C 42 at which the FA2 signal is to be activated during acceleration. Next a frequency
has to be set at which the FA2 signal is to be deactivated again, this is done using C 43.
2) Then configure under C 21 or C 22 one of the digital outputs 11 or 12 as FA1 or FA2 by entering the
parameter 01 for FA1 or 02 for FA2.
Remarks
• The transition of an FA1 or FA2 signal from the inactive to the active state is carried out with a delay of
approximately 60ms.

Remarks
• When the AL output is configured as normally closed contact (i.e. no alarm signal when output is closed)
it is important to remember that a time delay exists from the time the input power is switched on until the
AL output is closed (deactivated) and thus a trip condition is indicated for a short time.
• The programmable digital outputs (including an output configured as AL) are of open collector type and
so have different electrical characteristics compared with the alarm relay output (terminals AL0, AL1,
and AL2). Especially the maximum voltage and current load ratings are much more restrictive than is the
case with relay outputs.
• After the inverter power supply has been switched off, the AL output remains active until the DC bus
voltage has dropped below a certain level. This time is depending, among others, on the load applied to
the inverter.
• The delay from the time a trip occurs until the AL output is activated is about 300ms.

Configuration

Refer to the above table to configure the contacts AL0/AL1 and AL0/AL2 as normally closed or normally

Remarks
• After a trip has occured the trip message displayed is conserved even when the power to the inverter is
switched off. For this reason, this trip message can be displayed again when the inverter is switched on
afterwards. However, the inverter will be reset when it is switched off which means that the existance of a
trip message will not be indicated by the alarm relay contacts when the inverter is switched on again. If
the trip signalling must be kept even after the inverter has been switched on again, use external circuitry
to hold the alarm signal.
• When the alarm relay output is configured as normally closed contact (i.e. no alarm signal when output is
closed, this is the factory default) it is important to remember that a time delay exists from the time the
input power is switched on until the alarm output is closed (deactivated) and thus a trip condition is
indicated for a short time after switching on the input power.

Chapter 8 – Using the digital operator
Overview of parameter settings
In the following chapters all parameters that can be set using the digital operator are described and listed in
tables. Starting with chapter “Basic functions” the column “Standard setting” lists the factory preconfigured
parameter settings.
All the settings listed in the following tables are grouped by function groups so that all functions belonging to
the same group (e.g. function group “DC brake” with functions A 51 to A 55, chapter “Extended functions of
group A”) can be viewed as a whole.
The use of the functions listed in column “Display” have already been described in the previous chapters
“Operating procedure example” and “Digital operator keys”. Functions d 01 through d 09 are only designed
for displaying data, no parameters can be configured here.
Note: Starting with chapter “Basic functions” the *) marked column indicates whether parameters can be
changed during inverter operation (Y) or not (N).

DC braking
L100 series inverters have a configurable DC brake that is activated as soon as the stop command is issued. By
applying a strobed DC voltage to the motor’s stator a braking torque is induced into the rotor that effectively works
against the rotation of the motor. Usage of the DC brake makes possible high registration accuracy when carrying
out positioning work.
CAUTION
Usage of the DC brake causes an additional heating of the motor. For this
reason the DC brake should be configured with as short a braking torque and

PID control
Introduction
The PID closed loop control has been designed with a control variable of “frequency in Hz” where the proportional
gain (kp), the integral gain (TN), and the differential gain (TV) of the control algorithm can be set independently from
each other. The set value and the actual value are scaled in % (setting range 0–100%). For a better presentation of these
values they can be scaled and displayed in the desired physical engineering unit (e.g. flow or throughput of 0 to 30l/h).
The PID control output is limited to a lower limit of 0 Hz (or the frequency set under A 62) and to the frequency set
under A 04 (or A 61, respectively) as an upper limit. This ensures that the motor running direction will not be reversed
when a negative deviation is present.
In order to optimize the PID control’s behaviour it is advisable to keep acceleration and deceleration times as short as

The parameters of functions A 11 through A 14 are changed from Hz to % due to the PID control’s activation (done
using A 71) and to engineering units by setting function A 75. For this reason, function A 71 must be set to 01 before
the other functions are configured.
Displayed values
Function d 04 enables the display of the actual value while F 01 enables the display of the set value. These values can
be displayed in engineering units by setting function A 75.
When function F 01 is activated the PID set value will be displayed, but there is no permanent update of the displayed

permanently updated.
P, I and D gain
Although these gains can be set independently of each
other, there are interactions between them. When the P
gain (kp) is changed, the effective I gain changes (TN*)
also. Only when k p = 1, the effective I gain (TN*) is equal
to the I gain that had been entered (TN). When kp is not
equal to 1, TN* can be calculated as follows:
TN* = TN * kp (refer to the figure on the right).

Automatic Voltage Regulation (AVR)
The AVR function causes motor voltage stabilization when DC voltage is fluctuating (e.g. due to an instable mains
supply or a dropping or excessive DC voltage as a result of too short acceleration or deceleration times) and thus
ensures a high torque (especially during acceleration).
Dynamic braking (without the use of the AVR function) cauese a rise in DC voltage during deceleration (especially
when very short deceleration times have been set) which in turn causes a rise in motor voltage. This raised motor
voltage causes a higher braking torque. For this reason, the AVR function can be deactivated for deceleration using
A 81.

restart if a running command is being active at the same time. Additional
precautions must be taken for personnell not to get endangered in case of a

In standard setting any inverter failure will cause a trip condition. An automatic motor restart following an inverter
trip is possible with:

The overload restriction function is used to limit motor current.
During acceleration, the rise in frequency is stopped as soon as the output
current exceeds the configured overload limit. During normal static
operation the output frequency is reduced instead in order to reduce the
load current (the time constant for control near the overload limit can be
entered under b 23). When the output current falls below the configured
overload limit, the frequency is raised again to the configured set value.
The overload limit can be deactivated during acceleration (refer to b 21)
so that larger currents are allowed for a short time.
It must be noted however, that the overload limit can not prevent an
inverter trip and an inverter shutdown due to a sudden overcurrent
(caused for example by a short circuit condition).

Overcurrent
protection
When the output of the inverter is short circuited, the
motor is locked, or a heavy load is suddenly applied,
and the inverter output current exceeds a predetermined level, the inverter is shut off.
Overload
protection
When a motor overload is detected by the electronic
thermal function, the inverter is shut off.
E005
Overvoltage
protection
When the inverter DC bus voltage exceeds a
predetermined level due to regenerative energy from the
motor, this trip occures and the inverter is shut off.
E007
EEPROM error
(Note)
When the inverter memory has a problem due to noise or
excessive temperature rise, this trip occurs and the
inverter is shut off.
E008
Undervoltage
protection
A decrease of DC bus voltage may result in improper
function of the control unit. It may also cause motor
heating and low torque. The inverter is shut off when the
DC bus voltage goes below a certain level.
E009
CPU error
Malfunction or abnormality of the CPU. The inverter is
shut off.
E011
E022
External trip
A trip signal from external equipment shuts off the
inverter. It is necessary to assign the external trip to an
intelligent terminal.
E012
USP error
Indicates an error when power is turned on while the
inverter run is enabled (when USP function is selected).
E013
Ground fault
protection
The inverter is protected by detection of ground faults
between the drive output and the motor at power on.
Protection is for the inverter only and not for humans.
E014
Input overvoltage
When the input voltage is higher than a specified value, it
is detected and 100 seconds after power is turned on, the
inverter is shut off.
E015
Thermal protection
When the temperature of the inverter module is beyond
specification, the thermal sensor in the inverter module
detects the temperature and the inverter is shut off.
E021
PTC error
When the resistance value of the external thermistor is too
large, the equipment detects the abnormal condition of the
thermistor and then shuts off the inverter (when PTC
function is selected).
E035
Note: If an EEPROM error occurs, be sure to observe ist value. If power is turned off while the RS input
terminal is held ON, the EEPROM error occurs when power is turned back on.

Notes on technical specifications:
Note 1: Protective structure is based upon EN60529
Note 2: The applicable motor is a Hitachi standard four-pole motor. When using another motor, make
sure that the rated motor current does not exceed the rated inverter current.
Note 3: The output voltage will decrease if input voltage decreases.
Note 4a: The initial data setting values of 005N/011N are same as 007N/015N. So be sure to set the
correct values under b 12 and b 22 of 005N/007N for each motor first.
Note 4b: The initial data setting value of 030H is same as 040H. So be sure to set the values under
b 12 and b 22 of 030H for the motor first.
Note 5: Confirm with the motor manufacturer the motors maximum rpm when using a motor running
at frequencies higher than 50/60Hz
Note 6: Torque will be reduced when the base frequency exceeds 50Hz.
Note 7: In the range of 40 to 50°C reduce the carrier frequency to 2kHz and derate the output current
to 80% of the rated current, and remove the top cover.

Function description
The inverter can now be started via input 1 (forward run) or input 2 (reverse run). If
the inputs RV and FW are both closed, the inverter is stopped.
By adjusting the external potentiometer the desired frequency set value (voltage set
value) can be set.
The analog meter can be used to display the frequency (parameter 00 must be set
under C 23) or the motor current (parameter 01 must be set under C 23). With
function b 81 the displayed frequency or current value can be adjusted to the

The inputs 1 and 2 are used exactly the way as described in the previous example.
Digital input 3 (configured as AT) can be used to switch from voltage set value (0–
10V) to current set value (4–20mA). If none of the digital inputs has been configured
as AT then the voltage set value present on terminal O and the current set value
present on terminal OI will be added.
Instead of a fixed wiring or one that uses a switch connected to terminal 3 function
A 13 can be set to 01 (digital input 3 will then be configured as normally closed
contact).
This wiring example also incorporates a thermal motor protection using a thermistor.
It is important here that a screened control cable is used and that the thermistor
cables are installed at a safe distance from the motor cables. However, the screening
must only be grounded on the inverter side.

Function description
The inputs 1 and 2 are used exactly the way as described in the previous example.
When one or both of the multistage frequency inputs CF1 and CF2 are activated then
the current active frequency output is superseded by the fixed frequency set by the
combination of inputs CF1 and CF2. Consequently the motor is accelerated or
decelerated until the new frequency is reached. When none of the inputs CF1 and
CF2 is activated, then the frequency set value can be set by the terminals O (voltage
set value) or OI (current set value). In this example, the wiring of terminals O or OI
has not been included for simplicity.
The logical levels necessary for the various multistage frequency inputs to produce a
certain frequency are described under functions F 01 and A 20 through A 35.
This wiring example also contains the parameters that must be entered so that the
described signals will be output on terminals 11 and 12. The output signal type
(normally open or normally closed) can be set using function C 21 for ditital output
11 and function C 22 for ditital output 12.

Chapter 13 – The optional remote operators
Connection of the remote operator
Before the optional remote operators DOP, DRW, or OPE-J can be connected the power supply to the
inverter has to be switched off. Then the cable must be plugged into the inverter as shown in the figure. Now
the power supply can be switched on again. The inverter is now in monitor mode and on the remote
operator’s LCD display the message FS000.0... is shown.
OPE-J
DOP, DRW
The parameters that have been configured using L100 series inverters can now be copied to other inverters
using the copy unit DRW-0A2. The old model DRW-0A can not be used for this purpose.
When inverters are operated with a remote operator connected, the following items must be noted:
- The remote operator’s cable must not be attached or removed during operation (i.e. if the power supply to
the inverter is switched on).
- The digital operator of the inverter can not be used while the remote operators DOP or DRW are being
connected.
- All remote operator keys are inactive except the STOP/RESET key while the remote operator OPE-J is
being connected (also refer to the description of function b 89 in chapter 8 under “Extended functions of
group B”).
Set the dip switches on the back of the remote operator as follows:
ON

When ON, the copy unit cannot be
read out. When the READ key is
pressed, the message RD LOCK

heating and low torque. The inverter is shut off when the
DC bus voltage goes below a certain level.
Under. V
CPU error
Malfunction or abnormality of the CPU.
The inverter is shut off.
CPU1
CPU2
External trip
A trip signal from external equipment shuts off the
inverter. It is necessary to assign the external trip to an
intelligent input terminal.
EXTERNAL
USP error
Indicates an error when power is turned on while the
inverter run is enabled (when USP function is selected).
USP
Ground fault
protection
The inverter is protected by detection of ground faults
between the drive output and the motor at power on.
Protection is for the inverter only and not for humans.
GND. Flt
Thermal
protection
When the temperature of the inverter module is beyond
specification, the thermal sensor in the inverter module
detects the temperature and the inverter is shut off.

After having pressed the COPY key, wait for at least 6 seconds before pressing another key on the
operator or before sending a reset command to the inverter. If an operator key is pressed or if a reset is
sent to the inverter before this time has elapsed then the data may not be stored correctly.
The example described in the following table somewhat resembles the previous one, but here first a few
parameters of inverter A are changed using the copy unit before the changed data are transferred to three
other inverters B, C, and D.

Notes:
-
Data from L100 series inverters can only be copied using the copy unit DRW-0A2. The previous copy
unit version DRW-0A can not be used for this purpose.
-
The trip history monitor contents and the software lock configuration (F-25) cannot be copied using the
copy unit.
-
Never copy parameter settings of 200V series inverters to those from the 400V series (or the other way
round). If settings are copied by mistake to inverters of a different input voltage rating then correct F-03.
-
Never copy parameter settings from Japanese series inverters to those of the European or American
version series (or the other way round)
-
If the V/F characteristic parameter is copied to an inverter with a different maximum capacity (e.g. from
L100-004NFE to L100-022NFE) so the parameters of functions F-23, F-24, and F-33 will have to be
changed according to the maximum motor size.

Chapter 14 – Service and warranty
Chapter 14 – Service and warranty
Should you encounter any problems with your Hitachi inverter, please consult your local sales representative.
Please provide the following information about your inverter:
1) The exact inverter model name (this information can be found on the inverter nameplate next to Model:)
2) Date of purchase
3) Serial number (this information can be found on the inverter nameplate next to MFG. No:)
4) Exact description of the problems that occured in conjunction with the inverter.
If some of the information on the nameplate should be illegible please only supply the information that can
be clearly read. To reduce non-operation time it is recommended to stock a spare inverter.
Warranty
The warranty period for Hitachi inverters shall be under
normal inverter installation and handling conditions twelve
(12) months from the date of installation and eighteen (18)
months from the date of production.
This warranty will not cover the following cases, even when the date the problem arises lies
within the warranty period. In these cases the costs for service that the purchaser has ordered
will be charged to the purchaser himself:
Inverter damage or malfunction which can be attributed to misoperation, inverter
modifications done by the purchaser, improper repair, or excessively high power supply
voltages.
Inverter damage or malfunction which were caused by the inverter falling down after its
purchase.
Inverter damage or malfunction which were caused by fire, earthquake, water damages,
lightning, pollution, or other natural disasters.
If service has been ordered by the purchaser at the inverter installation site, then all costs that
arise will have to be taken over by the purchaser.
Please always keep this manual at hand.

Appendix A – Printed form for user defined parameter settings
Appendix A – Printed form for user defined parameter
settings
L100 series inverters provide many functions whose parameters can be set by the user. It is recommended
that the parameters that have been set by the user be recorded to speed the investigation and repair in the
event of a failure. You can use one of the “Set value” columns that have been provided in this chapter for
your convenience.
If the information in the column “Function” should not provide a sufficient explanation you can still use the
extensive function descriptions contained in chapter 8 “Using the digital operator”.
This information is written on the

L100 series inverters provide many functions whose parameters can be set by the user. It is recommended
that the parameters that have been set by the user be recorded to speed the investigation and repair in the
event of a failure. You can use one of the “Set value” columns that have been provided in this chapter for
your convenience.
This information is written on the
nameplate located on the right side

Appendix C – Initializing the inverter
Appendix C – Initializing the inverter
If it becomes necessary to initialize the inverter (i.e. reset the inverter to the factory standard settings or just
clearing the trip history register) you will have to do the following:
First refer to the nameplate to find out if the inverter is a European version (L100-####FE) or an American
version (L100-####FU).
Then set the correct national version under b 85 by entering the parameter 01 for the American version and
parameter 02 for the European version.
Use function b 84 to determine whether only the trip history register is to be cleared (parameter 00) or
whether the inverter is to be reset to the factory standard settings (parameter 01). Then you will have to
proceed as follows:
1) Simultaneously press the FUNC key and both direction (arrow) keys on the digital operator.
2) While holding down the mentioned keys press the STOP key for a short time and wait for about 3
seconds until the blinking message d 00 is shown on the display.
3) Now release all keys again. The initializing phase that now begins will be complete as soon as the
display 00 appears (output frequency display).
The inverter power supply must not be switched off before the initializing phase has been completed.
Furthermore it is important to know that inverter initializing cannot be carried out with the remote operator,
the copy unit, or the OPE-J operator being connected.
