CAUTION: Remarks for using ground fault interrupter breakers in the
main power supply: Adjustable frequency inverters with CE-filters (RFI­filter) and shielded (screened) motor cables have a higher leakage current
toward Earth GND. Especially at the moment of switching ON this can
cause an inadvertent trip of ground fault interrupters. Because of the
rectifier on the input side of the inverter there is the possibility to stall the
switch-off function through small amounts of DC current. Please observe
the following: • Use only short time-invariant and pulse current-sensitive
ground fault interrupters with higher trigger current. • Other components
should be secured with separate ground fault interrupters. • Ground fault
interrupters in the power input wiring of an inverter are not an absolute
protection against electric shock.

CAUTION: Be sure to install a fuse in each phase of the main power
supply to the inverter. Otherwise, there is the danger of fire.

CAUTION: For motor leads, ground fault interrupter breakers and
electromagnetic contactors, be sure to size these components properly
(each must have the capacity for rated current and voltage). Otherwise,
there is the danger of fire.

Warnings for Configuring Drive Parameters

SJ100 Inverter

vii

WARNING: When parameter B_12, level of electronic thermal setting, is
set to device FLA rating (Full Load Ampere nameplate rating), the device
provides solid state motor overload protection at 115% of device FLA or
equivalent. Parameter B_12, level of electronic thermal setting, is a
variable parameter.

Cautions for Configuring Drive Parameters

CAUTION: Be careful to avoid specifying a braking time that is long
enough to cause motor overheating. If you use DC braking, we recom­mend using a motor with a built-in thermistor, and wiring it to the
inverter’s thermistor input (see “Thermistor Thermal Protection” on
page 4–22). Also refer to the motor manufacturer’s specifications for
duty-cycle recommendations during DC braking.

Warnings for Operations and Monitoring

WARNING: Be sure to turn ON the input power supply only after closing
the front case. While the inverter is energized, be sure not to open the
front case. Otherwise, there is the danger of electric shock.

…. 3–26

…… 4–3

WARNING: Be sure not to operate electrical equipment with wet hands.
Otherwise, there is the danger of electric shock.

WARNING: While the inverter is energized, be sure not to touch the
inverter terminals even when the motor is stopped. Otherwise, there is the
danger of electric shock.

WARNING: If the Retry Mode is selected, the motor may suddenly
restart after a trip stop. Be sure to stop the inverter before approaching the
machine (be sure to design the machine so that safety for personnel is
secure even if it restarts.) Otherwise, it may cause injury to personnel.

WARNING: If the power supply is cut OFF for a short period of time, the
inverter may restart operation after the power supply recovers if the Run
command is active. If a restart may pose danger to personnel, so be sure
to use a lock-out circuit so that it will not restart after power recovery.
Otherwise, it may cause injury to personnel.

WARNING: The Stop Key is effective only when the Stop function is
enabled. Be sure to enable the Stop Key separately from the emergency
stop. Otherwise, it may cause injury to personnel.

WARNING: During a trip event, if the alarm reset is applied and the Run
command is present, the inverter will automatically restart. Be sure to
apply the alarm reset only after verifying the Run command is OFF.
Otherwise, it may cause injury to personnel.

WARNING: Be sure not to touch the inside of the energized inverter or to
put any conductive object into it. Otherwise, there is a danger of electric
shock and/or fire.

WARNING: If power is turned ON when the Run command is already
active, the motor will automatically start and injury may result. Before
turning ON the power, confirm that the RUN command is not present.

WARNING: When the Stop key function is disabled, pressing the Stop
key does not stop the inverter, nor will it reset a trip alarm.

WARNING: Be sure to provide a separate, hard-wired emergency stop
switch when the application warrants it.

WARNING: If the power is turned ON and the Run command is already
active, the motor starts rotation and is dangerous! Before turning power
ON, confirm that the Run command is not active.

WARNING: After the Reset command is given and the alarm reset
occurs, the motor will restart suddenly if the Run command is already
active. Be sure to set the alarm reset after verifying that the Run
command is OFF to prevent injury to personnel.

WARNING: You may need to disconnect the load from the motor before
performing auto-tuning. The inverter runs the motor forward and
backward for several seconds without regard to load movement limits.

Warnings and Cautions for Troubleshooting and Maintenance

ix

WARNING: Wait at least five (5) minutes after turning OFF the input
power supply before performing maintenance or an inspection. Other­wise, there is the danger of electric shock.

WARNING: Make sure that only qualified personnel will perform
maintenance, inspection, and part replacement. Before starting to work,
remove any metallic objects from your person (wristwatch, bracelet,
etc.). Be sure to use tools with insulated handles. Otherwise, there is a
danger of electric shock and/or injury to personnel.

WARNING: Never remove connectors by pulling on its wire leads (wires
for cooling fan and logic P.C.board). Otherwise, there is a danger of fire
due to wire breakage and/or injury to personnel.

CAUTION: Do not connect the megger to any control circuit terminals
such as intelligent I/O, analog terminals, etc. Doing so could cause
damage to the inverter.

CAUTION: Never test the withstand voltage (HIPOT) on the inverter.
The inverter has a surge protector between the main circuit terminals
above and the chassis ground.

HIGH VOLTAGE: Be careful not to touch wiring or connector terminals
when working with the inverters and taking measurements. Be sure to
place the measurement circuitry components above in an insulated
housing before using them.

General Warnings and Cautions

WARNING: Never modify the unit. Otherwise, there is a danger of electric shock and/
or injury.

CAUTION: Withstand voltage tests and insulation resistance tests (HIPOT) are
executed before the units are shipped, so 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 during operation.

CAUTION: Be sure to connect the grounding terminal to earth ground.

CAUTION: When inspecting the unit, be sure to wait five minutes after tuning OFF the

power supply before opening the cover.

When there has been a sudden power failure while an operation instruction is active,
then the unit may restart operation automatically after the power failure has ended. If
there is a possibility that such an occurrence may harm humans, then install an electro­magnetic contactor (Mgo) on the power supply side, so that the circuit does not allow
automatic restarting after the power supply recovers. If the optional remote operator is
used and the retry function has been selected, this will also cause automatic restarting
when a Run command is active. So, please be careful.

CAUTION: Do not insert leading power factor capacitors or surge absorbers between
the output terminals of the inverter and motor.

CAUTION: MOTOR TERMINAL SURGE VOLTAGE SUPPRESSION FILTER
(For the 400 V CLASS)

In a system using an inverter with the voltage control PWM system, a voltage surge
caused by the cable constants such as the cable length (especially when the distance
between the motor and inverter is 10 m or more) and cabling method may occur at the
motor terminals. A dedicated filter of the 400 V class for suppressing this voltage surge
is available. Be sure to install a filter in this situation.

SJ100 Inverter

CAUTION: SUPPRESSION FOR NOISE INTERFERENCE FROM INVERTER

The inverter uses many semiconductor switching elements such as transistors and
IGBTs. Thus, a radio receiver or measuring instrument located near the inverter is
susceptible to noise interference.
To protect the instruments from erroneous operation due to noise interference, they
should be used well away from the inverter. It is also effective to shield the whole
inverter structure.
The addition of an EMI filter on the input side of the inverter also reduces the effect of
noise from the commercial power line on external devices.
Note that the external dispersion of noise from the power line can be minimized by
connecting an EMI filter on the primary side of inverter.

CAUTION: EFFECTS OF POWER DISTRIBUTION SYSTEM ON INVERTER

In the cases below involving a general-purpose inverter, a large peak current can flow on
the power supply side, sometimes destroying the converter module:

1. The unbalance factor of the power supply is 3% or higher.

2. The power supply capacity is at least 10 times greater than the inverter capacity (or
the power supply capacity is 500 kVA or more).

3. Abrupt power supply changes are expected, due to conditions such as:
a. Several inverters are interconnected with a short bus.
b. A thyristor converter and an inverter are interconnected with a short bus.
c. An installed phase advance capacitor opens and closes.

Where these conditions exist or when the connected equipment must be highly reliable,
you MUST install an input-side AC reactor of 3% (at a voltage drop at rated current)
with respect to the supply voltage on the power supply side. Also, where the effects of an
indirect lightning strike are possible, install a lightning conductor.

xii

CAUTION: When the EEPROM error E08 occurs, be sure to confirm the setting values
again.

CAUTION: When using normally closed active state settings (C_11 to C_16) for exter-
nally commanded Forward or Reverse terminals [FW] or [RV], the inverter may start
automatically when the external system is powered OFF or disconnected from the
inverter! So, do not use normally closed active state settings for Forward or Reverse
terminals [FW] or [RV] unless your system design protects against unintended motor
operation.

CAUTION: In all the illustrations in this manual, covers and safety devices are
occasionally removed to describe the details. While operating the product, make sure
that the covers and safety devices are placed as they were specified originally and
operate it according to the instruction manual.

Motor Overload Protection

Hitachi SJ100 inverters provide solid state motor overload protection, which depends on
the proper setting of the following parameters:

• B_12 “electronic overload protection”

• B212 “electronic overload protection, 2nd motor”

Set the rated current [Amperes] of the motor(s) with the above parameters. The setting
range is 0.5 * rated current to 1.2 * rated current.

WARNING: When two or more motors are connected to the inverter, they cannot be
protected by the electronic overload protection. Install an external thermal relay on each
motor.

Introduction

Main Features

Congratulations on your purchase of an SJ100
Series Hitachi inverter! This inverter drive
features state-of-the-art circuitry and components
to provide high performance. The housing
footprint is exceptionally small, given the size of
the corresponding motor. The Hitachi SJ100
product line includes more than a dozen inverter
models to cover motor sizes from 1/4 horsepower
to 10 horsepower, in either 230 VAC or 460 VAC
power input versions. The main features are:

• 200V and 400V Class inverters

• UL or CE version available

• Sensorless vector control

• Regenerative braking circuit

• Convenient keypad for parameter settings

• Built-in RS-422 communications interface to

allow configuration from a PC and for field
bus external modules.

• Sixteen programmable speed levels

• Motor constants are programmable, or may be set via auto-tuning

• PID control adjusts motor speed automatically to maintain a process variable value

The design in Hitachi inverters overcomes many of the traditional trade-offs between
speed, torque and efficiency. The performance characteristics are:

• High starting torque of 200% rating or greater

• Continuous operation at 100% torque within a 1:10 speed range (6/60 Hz / 5/50 Hz)

without motor derating

• Fan has ON/OFF selection to provide longer life for cooling fan (on models with fan)

Model SJ100-004NFU

A full line of accessories from Hitachi is available to
complete your motor application. These include:

• Digital remote operator keypad

• Braking resistors (shown at right)

• Radio noise filters

• CE compliance filters

• DIN rail mounting adapter (35mm rail size)

Operator Interface Options

The optional SRW-0EX digital operator / copy
unit is shown to the right. It has the additional
capability of reading (uploading) the parameter
settings in the inverter into its memory. Then you
can connect the copy unit on another inverter and
write (download) the parameter settings into that
inverter. OEMs will find this unit particularly
useful, as one can use a single copy unit to
transfer parameter settings from one inverter to
many.

SJ100 Inverter Specifications

Footnotes for the preceding table and the tables that follow:

Note 1: The protection method conforms to JEM 1030.
Note 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.

Note 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.

Note 4: To operate the motor beyond 50/60 Hz, consult the motor manufacturer for

the maximum allowable rotation speed.

Note 5: When SLV is selected, please set the carrier frequency higher than 2.1 kHz.
Note 6: At the rated voltage when using a Hitachi standard 3-phase, 4-pole motor

(when selecting sensorless vector control—SLV).

Note 7: 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. If
a large regenerative torque is required, the optional regenerative braking
resistor should be used.

Note 8: 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.

Note 9: If operating the inverter at 40 to 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.

Note 10: The storage temperature refers to the short-term temperature during transport.
Note 11: Conforms to the test method specified in JIS C0911 (1984). For the model

types excluded in the standard specifications, contact your Hitachi sales repre­sentative.

Note 12: The input voltage of xxLFU is 230V.

Derating Curves

Getting Started

SJ100 Inverter Specifications

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 SJ100 inverter model number.

Introduction to Variable-Frequency Drives

The Purpose of Motor Speed Control for Industry

Getting Started

What is an Inverter?

Introduction to Variable-Frequency Drives

Hitachi inverters provide speed control for 3-phase AC induction motors. You connect
AC power to the inverter, and connect the inverter to the motor. Many applications
benefit from a motor with variable speed, in several ways:

• Energy savings — HVAC

• Need to coordinate speed with an adjacent process—textiles and printing presses

• Need to control acceleration and deceleration (torque)

• Sensitive loads — elevators, food processing, pharmaceuticals

The term inverter and variable-frequency drive are related and somewhat interchange-
able. An electronic motor drive for an AC motor can control the motor’s speed by
varying the frequency of the power sent to the motor.

An inverter, in general, is a device that converts DC power to AC power. The figure
below shows how the variable-frequency drive employs an internal inverter. The drive
first converts incoming AC power to DC through a rectifier bridge, creating an internal
DC bus voltage. Then the inverter circuit converts the DC back to AC again to power the
motor. The special inverter can vary its output frequency and voltage according to the
desired motor speed.

The simplified drawing of the inverter shows three double-throw switches. In Hitachi
inverters, the switches are actually IGBTs (isolated gate bipolar transistors). Using a
commutation algorithm, the microprocessor in the drive switches the IGBTs on and off
at a very high speed to create the desired output waveforms. The inductance of the motor
windings helps smooth out the pulses.

Torque and Constant Volts/Hertz Operation

In the past, AC variable speed drives used an
open loop (scalar) technique to control speed.
The constant-volts-per-hertz operation
maintains a constant ratio between the applied
voltage and the applied frequency. With these
conditions, AC induction motors inherently
delivered constant torque across the operating
speed range. For some applications, this scalar
technique was adequate.

Today, with the advent of sophisticated micro­processors and digital signal processors (DSPs),
it is possible to control the speed and torque of AC induction motors with unprecedented
accuracy. The SJ100 utilizes these devices to perform complex mathematical calcula­tions required to achieve superior performance. The technique is referred to as sensorless
vector control. It allows the drive to continuously monitor its output voltage and current,
and their relationship to each other. From this it mathematically calculates two vector
currents. One vector is related to motor flux current, and the other to motor torque
current. The ability to separately control these two vectors is what allows the SJ100 to
deliver extraordinary low-speed performance and speed control accuracy.

Inverter Input and Three-Phase Power

The Hitachi SJ100 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. Accordingly, a 200V class inverter requires
(nominal) 200 to 240VAC, and a 400V class inverter requires from 380 to 460VAC.
Some 200V class inverters will accept single-phase or three-phase power, but all 400V
class inverters require a three-phase power supply.

TIP: If your application only has single phase power available, refer to SJ100 inverters
of 3HP or less; they can accept single phase input power.

The common terminology for single phase power is Line (L) and Neutral (N). Three­phase power connections are usually labeled Line 1 (L1), Line 2 (L2) and Line 3 (L3). In
any case, the power source should include an earth ground connection. That ground
connection will need to connect to the inverter chassis and to the motor frame (see

the Inverter Output to Motor” on page 2–18).

Introduction to Variable-Frequency Drives

Inverter Output to the Motor

Getting Started

The AC motor must be connected only to the inverter’s
output terminals. The output terminals are uniquely
labeled (to differentiate them from the input terminals)
with the designations U/T1, V/T2, and W/T3. This
corresponds to typical motor lead connection designa­tions T1, T2, and T3. It is often not necessary to connect
a particular inverter output to a particular motor lead for
a new application. The consequence of swapping any
two of the three connections is the reversal of the motor
direction. In applications where reversed rotation could
cause equipment damage or personnel injury, be sure to verify direction of rotation
before attempting full-speed operation. For safety to personnel, you must connect the
motor chassis ground to the ground connection at the bottom of the inverter housing.

Notice the three connections to the motor do not include one marked “Neutral” or
“Return.” The motor represents a balanced “Y” impedance to the inverter, so there is no
need for a separate return. In other words, each of the three “Hot” connections serves
also as a return for the other connections, because of their phase relationship.

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. There­fore, this manual instructs you not to switch off power to the inverter while the motor is
running (unless it is an emergency stop). Also, do not install or use disconnect switches
in the wiring from the inverter to the motor (except thermal disconnect). Of course,
safety-related devices such as fuses must be in the design to break power during a
malfunction, as required by NEC and local codes.

Intelligent Functions and Parameters

Much of this manual is devoted to describing
how to use inverter functions and how to config­ure inverter parameters. The inverter is micro­processor-controlled, and has many independent
functions. The microprocessor has an on-board
EEPROM for parameter storage. The inverter’s
front panel keypad provides access to all
functions and parameters, which you can access
through other devices as well. The general name
for all these devices is the digital operator, or
digital operator panel. Chapter 2 will show you
how to get a motor running, using a minimal set
of function commands or configuring parame­ters.

The optional read/write programmer will let you
read and write inverter EEPROM contents from
the programmer. This feature is particularly
useful for OEMs who need to duplicate a particu­lar inverter’s settings in many other inverters in
assembly-line fashion.

Braking

In general, braking is a force that attempts to slow or stop motor rotation. So it is associ­ated with motor deceleration, but may also occur even when the load attempts to drive
the motor faster than the desired speed (overhauling). If you need the motor and load to
decelerate quicker than their natural deceleration during coasting, we recommend
installing a braking resistor. The dynamic braking unit (built into the SJ100) sends
excess motor energy into a resistor to slow the motor and load (see

page 5–2 and “Dynamic Braking” on page 5–5 for more information). For loads that

continuously overhaul the motor for extended periods of time, the SJ100 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. For a particular inverter, motor, and load, there will
be a range of practically achievable accelerations and decelerations.

the time required to go from a stop to

resulting slope (speed change divided by time)
is the acceleration or deceleration. An increase
in output frequency uses the acceleration

slope. The accel or decel time a particular
speed change depends on the starting and

ending frequencies. However, the slope is constant, corresponding to the full-scale accel
or decel time setting. For example, the full-scale acceleration setting (time) may be 10
seconds—the time required to go from 0 to 60 Hz.

The SJ100 inverter can store up to 16 preset
speeds. And, it can apply separate acceleration
and deceleration transitions from any preset to
any other preset speed. A multi-speed profile
(shown at right) uses two or more preset
speeds, which you can select via intelligent
input terminals. This external control can

The inverter can drive the motor in either

Frequently Asked Questions

Q. What is the main advantage in using an inverter to drive a motor, compared to

alternative solutions?

A. 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.

Q. The term “inverter” is a little confusing, since we also use “drive” and “amplifier”

to describe the electronic unit that controls a motor. What does “inverter” mean?

A. The terms inverter, drive, and amplifier are used somewhat interchangeably

in industry. Nowadays, the terms drive, variable-frequency drive, variable-
speed drive, and inverter are generally used to describe electronic, micropro­cessor-based motor speed controllers. In the past, variable-speed drive also
referred to various mechanical means to vary speed. Amplifier is a term
almost exclusively used to describe drives for servo or stepper motors.

Q. Although the SJ100 inverter is a variable speed drive, can I use it in a fixed-speed

application?

A. Yes, sometimes an inverter can be used simply as a “soft-start” device,

providing controlled acceleration and deceleration to a fixed speed. Other
functions of the SJ100 may be useful in such applications, as well. However,
using a variable speed drive can benefit many types of industrial and
commercial motor applications, by providing controlled acceleration and
deceleration, high torque at low speeds, and energy savings over alternative
solutions.

Getting Started

Q. Can I use an inverter and AC induction motor in a positioning application?

A. That depends on the required precision, and the slowest speed the motor will

must turn and still deliver torque. The SJ100 inverter will deliver full torque
while turning the motor at only 0.5 Hz (15 RPM). DO NOT use an inverter if
you need the motor to stop and hold the load position without the aid of a
mechanical brake (use a servo or stepper motion control system).

Q. Does the optional digital operator interface or the PC software (DOP Professional)

provide features beyond what is available from the keypad on the unit?

A. Yes. However, note first that the same set of parameters and functions are

equally accessible from either the unit’s keypad or from remote devices. The
DOP Professional PC software lets you save or load inverter configurations
to or from a disk file. And, the hand-held digital operator provides hard­wired terminals, a safety requirement for some installations.

Frequently Asked Questions

Q. Why does the manual or other documentation use terminology such as “200V

class” instead of naming the actual voltage, such as “230 VAC?”

A. A specific inverter model is set at the factory to work across a voltage range

particular to the destination country for that model. The model specifications
are on the label on the side of the inverter. A European 200V class inverter
(“EU” marking) has different parameter settings than a USA 200V class
inverter (“US” marking). The initialization procedure (see

Factory Default Settings” on page 6–8) can set up the inverter for European

or US commercial voltage ranges.

Q. Why doesn’t the motor have a neutral connection as a return to the inverter?

A. The motor theoretically represents a “balanced Y” load if all three stator

windings have the same impedance. The Y connection allows each of the
three wires to alternately serve as input or return on alternate half-cycles.

Q. Does the motor need a chassis ground connection?

A. Yes, for several reasons. Most importantly, this provides protection in the

event of a short in the motor that puts a hazardous voltage on its housing.
Secondly, motors exhibit leakage currents that increase with aging. Lastly, a
grounded chassis generally emits less electrical noise than an ungrounded
one.

Restoring

Q. What type of motor is compatible with the Hitachi inverters?

A. Motor type – It must be a three-phase AC induction motor. Use an inverter-

grade motor that has 800V insulation for 200V class inverters, or 1600V
insulation for 400V class.
Motor size – In practice, it’s better to find the right size motor for your
application; then look for the inverter to match the motor.

NOTE: There may be other factors that will affect motor selection, including heat dissi­pation, motor operating speed profile, enclosure type, and cooling method.

Q. How many poles should the motor have?

A. Hitachi inverters can be configured to operate motors with 2, 4, 6, or 8 poles.

The greater the number of poles, the slower the top motor speed will be, but
it will have higher torque at the base speed.

Q. Will I be able to add dynamic (resistive) braking to my Hitachi SJ100 drive after

the initial installation?

A. Yes. The SJ100 inverter already has a dynamic braking circuit built in. Just

add the resistor sized to meet the braking requirements. More information on
dynamic braking is located in Chapter 5.

SJ100 Inverter

1–25

Q. How will I know if my application will require resistive braking?

A. For new applications, it may be difficult to tell before you actually test a

motor/drive solution. In general, some applications can rely on system losses
such as friction to serve as the decelerating force, or otherwise can tolerate a
long decel time. These applications will not need dynamic braking.
However, applications with a combination of a high-inertia load and a
required short decel time will need dynamic braking. This is a physics
question that may be answered either empirically or through extensive calcu­lations.

Q. 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?

A. The purpose of these noise filters is to reduce the inverter electrical noise so

the operation of nearby electrical devices is not affected. Some applications
are governed by particular regulatory agencies, and noise suppression is
mandatory. In those cases, the inverter must have the corresponding noise
filter installed. Other applications may not need noise suppression, unless
you notice electrical interference with the operation of other devices.

Getting Started

Q. The SJ100 features a PID loop feature. PID loops are usually associated with

chemical processes, heating, or process industries in general. How could the PID
loop feature be useful in my application?

A. You will need to determine the particular main variable in your application

the motor affects. That is the process variable (PV) for the motor. Over time,
a faster motor speed will cause a faster change in the PV than a slow motor
speed will. By using the PID loop feature, the inverter commands the motor
to run at the optimal speed required to maintain the PV at the desired value
for current conditions. Using the PID loop feature will require an additional
sensor and other wiring, and is considered an advanced application.

Unpacking and Inspection

Please take a few moments to unpack your new SJ100 inverter and perform these steps:

1. Look for any damage that may have occurred during shipping.

2. Verify the contents of the box include:

a. One SJ100 inverter

b. One Instruction Manual with self-adhesive label for the inverter

c. One SJ100 Quick Reference Guide

d. One packet of desiccant—discard (not for human consumption)

3. Inspect the specifications label on the side of the inverter. Make sure it matches the

product part number you ordered.

Main Physical Features

and Installation

Inverter Mounting

The SJ100 Series inverters vary in size according to the current output rating and motor
size for each model number. All feature the same basic keypad and connector interface
for consistent ease of use. The inverter construction has a heat sink at the back of the
housing. The larger models include a fan(s) to enhance heat sink performance. The
mounting holes are pre-drilled in the heat sink for your convenience. Never touch the
heat sink during or just after operation; it can be very hot.

The electronics housing and front panel are built onto the front of the heat sink. The
front panel has three levels of physical access designed for convenience and safety:

First-level access – for basic use of inverter and editing parameters (power ON)

Second-level access – for editing parameters and wiring control signals (power ON)

Third-level access – for wiring the inverter power supply or motor (power OFF)

1. First-level Access — View the unit just as it

came from the box as shown. The four-digit
display can show a variety of performance
parameters. LEDs indicate whether the
display units are Hertz or Amperes. Other
LEDs indicate Power (external), and Run/
Stop Mode and Program/Monitor Mode
status. Membrane keys Run and Stop/Reset,
and a Min/Max frequency control knob
control motor operation. These controls and
indicators are usually the only ones needed
after the inverter installation is complete.
You can also access the modular jack for
connecting a programming or monitoring
device such as a PC (see Chapter 3). And,
you can access the two chassis GND screws
on the metal tab at the bottom of the inverter.

2. Second-level access — Locate the lift tab at the right lower corner of the front panel

near the safety warning message. Lift the corner to swing the half-door around to the
left. This exposes four more control buttons and some connectors.
The FUNC., , , and STR keys allow an operator to access and change the
inverter’s functions and parameter values. The two 8-position connectors provide the
interface for logic-level control signals. These signals are generally low-voltage in
nature and are appropriate for second-level access.

3. Third-level access — First, ensure no power

source of any kind is connected to the
inverter. If power has been connected, wait
five minutes after powerdown and verify
the Power LED is OFF to proceed. Then
locate the recessed retention screw on the
left side main front panel (it is along the
left hinge area on some models, or behind
the first access door on others). Use a small
screwdriver (Regular or Phillips) to loosen
the screw. Swing the door around to the
right to reveal the internal components of
the drive. The two-level tiered 12-position
terminal block accepts wires for the power
input and wires to the motor.

Notice the housing partition that lifts out to
allow full access to the terminals for wiring as
shown. Never operate the inverter drive with
the partition removed or the full access door
opened.
The alarm circuit connections are accessible
on the 3-position connector near the modular
connector on the rear of the main panel door.
The nearby relay provides both normally­open and normally-closed logic for interface
to an external alarm. The alarm circuit may
carry hazardous live voltages even when the
main power to the inverter is OFF. So, never
directly touch any terminal or circuit compo­nent. A notch in the removable partition
serves as the exit path for alarm circuit wiring.

Basic System Description

A motor control system will obviously include a motor and inverter, as well as a breaker
or fuses for safety. If you are connecting a motor to the inverter on a test bench just to get
started, that’s all you may need for now. But a system can also have a variety of
additional components. Some can be for noise suppression, while others may enhance
the inverter’s braking performance. The figure and table below show a system with all
the optional components you may need in your finished application.

Step-by-Step Basic Installation

WARNING: In the cases below involving a general-purpose inverter, a large peak
current can flow on the power supply side, sometimes destroying the converter module:

1.The unbalance factor of the power supply is 3% or higher.

2.The power supply capacity is at least 10 times greater than the inverter capacity
(or the power supply capacity is 500 kVA or more).

3.Abrupt power supply changes are expected, due to conditions such as:
a. Several inverters are interconnected with a short bus.
b. A thyristor converter and an inverter are interconnected with a short bus.
c. An installed phase advance capacitor opens and closes.

Where these conditions exist or when the connected equipment must be highly reliable,
you MUST install an input-side AC reactor of 3% (at a voltage drop at rated current)
with respect to the supply voltage on the power supply side. Also, where the effects of an
indirect lightning strike are possible, install a lightning conductor.

This section will guide you through the following basic steps of installation:

1. Study the warnings and instructions associated with mounting the inverter.

2. Select a suitable mounting location.

NOTE: If the installation is in an EU country, study the EMC installation guidelines in

Appendix C.

3. Place covers over the inverter’s ventilation openings to prevent debris from entering.

4. Check the inverter mounting dimensions for footprint and mounting hole locations.

5. Study the caution and warning messages associated with wiring the inverter.

6. Connect wiring for the inverter power input.

7. Connect wiring to the motor.

8. Remove any covers applied in Step 3 from the inverter’s ventilation openings.

CAUTION: The inverter is shipped with a plastic cover over the top vent grill.

REMOVE this cover after the installation is complete. Operation with this cover in place
will not allow proper cooling, and damage to the inverter may result.

9. Perform a powerup test.

10. Make observations and check your installation.
