The inverter uses plastic parts. When carrying the inve rter, handle it carefully to prevent damage to the
parts.
Do not carry the inverter by holding the front or terminal block cover. Doing so may cause the inverter
to fall. Do not install and operate the inverter if it is damaged or its p arts are missing.
(2) Surface on which to install the inverter
The inverter will reach a high temperature (up to about 150°C) during operation. Install the inverter on
a vertical wall surface made of nonflammable material (e.g., metal) to avoid the risk of fire.
Leave sufficient space around the inverte r. In particular, keep sufficient distance between the in verter
and other heat sources (e.g., braking resistors and reactors) if they are installed in the vicinity.
Keep enough clearance between the
inverter and the wiring ducts located
above and below the inverter to prevent
the latter from obstructing the ventilation
of the inverter.
*1 10 cm or more
*2 10 cm or more
A
clearance of 22 cm or more is required
for replacing the DC bus capacitors.

(3) Ambient temperature
Avoid installing the inverter in a place where the ambient temperature goes above or below the
allowable range (-10°C to +50°C), as defined by the standard inverter specification.
Measure the temperature in a position about 5 cm distant from the bottom-center point of the inverter,
and check that the measured temperature is within the allowable range.
Operating the inverter at a temperature outside this range will shorten the inverter life (especially the
capacitor life).
(4) Humidity
Avoid installing the inverter in a place where the relative humidity goes above or below the allowable
range (20% to 90% RH), as defined by the standard inverter specification.
Avoid a place where the inverter is subject to con densation.
Condensation inside the inverter will result in short circuits and malfunctioning of electronic p arts. Also
avoid places where the inverter is exposed to direct sunlight.
(5) Ambient air
Avoid installing the inverter in a place where the inverter is subject to dust, corrosive gases,
combustible gases, flammable gases, grinding fluid mist, or salt water.
Foreign particles or dust entering the inverter will cause it to fail. If you use the inverter in a
considerably dusty environment, install the inverter inside a totally enclosed panel.

Chapter 2 Installation and Wiring
(6) Installation method and position
Install the inverter vertically and securely with screws or bolts on a surface that is free from vibrations
and that can bear the inverter weight.
If the inverter is not installed vertically, its cooling performance may be degraded and tripping or
inverter damage may result.
(7) Mounting in an enclosure
When mounting multiple inverters in an enclosure with a ventilation fan, carefully design the layout of
the ventilation fan, air intake port, and inverters.
An inappropriate layout will reduce the inverter-cooling effect and raise the ambient temperature. Plan
the layout so that the inverter ambient temperature will remain within the allowable range.

Ventilation fan
Inverter
(Unacceptable)

Position of ventilation fan
(8) Reduction of enclosure size
If you mount the inverter inside an enclosure such that the heat sink of the inverter is positioned
outside the enclosure, the amount of heat produced inside the enclosure can be reduced and likewise
the size of the enclosure.
Mounting the inverter in an enclosure with the heat sink positioned outside requires an optional
dedicated special metal fitting.
To mount the inverter in an enclosure wit h the heat si nk positioned o utside, cut out the enclosure p anel
according to the specified cutting dimensions.
The cooling section (including the heat si nk) positioned outside the enclosure has a cooling fan.
Therefore, do not place the enclosure in any environment where it is exposed to waterdrops, oil mist,
or dust.

2.2 Wiring
WARNING
- Be sure to ground the inverter. Otherwise, you run the risk of electric shock or fire.
- Commit wiring work to a qualified electrician. Otherwise, you run the risk of electric shock or fire.
- Before wiring, make sure that the power supply is off. Otherwise, you run the risk of electric shock or
fire.
- Perform wiring only after installing the inverter. Otherwise, you run the risk of electric shock or injury.
- Do not remove rubber bushings from the wiring section. Otherwise, the edges of the wiring cover may
damage the wire, resulting in a short circuit or ground fault.
！
CAUTION
- Make sure that the voltage of AC power supply matches the rated voltage of your inverter. Otherwise,
you run the risk of injury or fire.
- Do not input single-phase power into the inverter. Otherwise, you run the risk of fire.
- Do not connect AC power supply to any of the output terminals (U, V, and W). Otherwise, you run the
risk of injury or fire.
- Do not connect a resistor directly to any of the DC terminals (PD, P, and N). Otherwise, you run the
risk of fire.
- Connect an earth-leakage breaker to the power input circuit. Otherwise, you run the risk of fire.
- Use only the power cables, earth-leakage breaker, and magnetic contactors that have the specified
capacity (ratings). Otherwise, you run the risk of fire.
- Do not use the magnetic contactor installed on the primary and secondary sides of the inverter to stop
its operation.
- Tighten each screw to the specified torque. No screws must be lef t loose. Otherwise, you run the risk
of fire.
- Before operating, slide switch SW1 in the inverter, be sure to turn off the power supply. Otherwise, you
run the risk of electric shock and injury.
- Since the inverter supports two modes of cooling-fan operation, the inverter power is not always off,
even when the cooling fan is stopped. Therefore, be sure to confirm that the power supply is off before
wiring. Otherwise, you run the risk of electric shock and injury.

* For the location of the slide switch, see page 2-9.

Chapter 2 Installation and Wiring
2 - 9
About the emergency stop function (disabled by the factory setting)
- The SJ700 series inverter has the function of "uncontrolled stopping by removal of motor power" in
accordance with Stop Cat egory 0 defined by EN60204-1. The inverter is also designed to comply with
Safety Category 3 of EN954-1. This function is generally called Safe Stop function.
- The emergency stop function shuts off the inverter output (i.e. stops the switching operation of the main
circuit elements) in response to a command from a hardware circuit via an intelligent input terminal
without the operation by internal CPU software.
Note: The emergency stop function does not electrically shut off the inverter but merely stops the switching
operation of the main circuit elements. Therefore, do not touch any terminals of the inverter or any
power lines, e.g., motor cables. Otherwise, electric shock, injury, or ground fault may result.
Note: All systems that include an inve rter must comply with the requirements of EN60204-1 (safety of
machinery) and other applicable standards. You must confirm the contents of standards applicable
to your system.
Note: Before installing a system using Safe Stop function, you must fully examine whether Safe Stop
function and the safety category to be applied are adequate for your system. For details, refer to the
standards required for your system.
Note: Every system must be configured with an inverter, a motor, and an external shutoff device. The
external shutoff device must at least comply with Safety Category 3 of EN954-1.
Note: Safe Stop function is not intended for electrical insulation between the inverter and motor. If
necessary, connect a shut off device (e.g., contactor) to the motor connection cable.
Note: Safe Stop function is not designed to prevent malfunctions in drive process control and a pplication
functions.
Note: Carefully note that digital outputs (i.e., relay and open collector outputs) are not rega rded as the
safety-related signals described here. The signals output from externally installed safety relays must
be used for the safety-related control circuits installed for your system.
- When the emergency stop function is enabled, intelligent input terminals 1 and 3 are used exclusively fo r
this function, and no other functions can be assigned to these terminals. Even if other functions have
been assigned to these terminals, these are automatically disabled and these terminals are used
exclusively for the emergency stop function.
Terminal [1] function:
This terminal always serves as the a (NO) contact for the reset (RS) signal.
This signal resets the inverter and releases the inverter from the trip due to emergency stop (E37.*).
Terminal [3] function:
This terminal always serves as the b (NC) contact for the emergency stop (EMR) signal.
This signal shuts off the inverter output without the operation by internal CPU software.
This signal makes the inverter trip due to emergency stop (E37.*).
Note: If intelligent input terminal 3 is left unconnected, the cable connected to the terminal is disconnected,
or the signal logic is improper , the inverter trips due to emergency stop (E37.*). If this occurs, check
and correct the wiring and signal logic, and then input the reset (RS) signal.
Only the reset (RS) signal input from intelligent input terminal [1] can release the inverter from
tripping due to emergency stop (E37.*). (The inverter cannot be released from the E37.* status by
any operation from the digital operator.)
- To enable the emergency stop function, set the slide lever of slide swit ch SW1 to ON. (With the factory
setting, slide switch SW1 is set to OFF to disable the function.)
Note: Before operating slide switch SW1, make sure that the input power supply is off.
Note: Carefully note that improperly turning slide switch SW1 on or off will automatically change function
assignments to the control terminals of the inverter.

*3 If function "18 (RS)" has been assigned to an intelligent input terminal other than intelligent input terminals [1] and [3] before slide
switch SW1 is set to ON, the input terminal setting for said terminal is automatically changed to "no (no function assigned)" when
slide switch SW1 is set to ON to prevent any duplication of terminal functions. Even if slide switch SW1 is subsequently returned
to OFF, the original function setting for said terminal will not be restored. If necessary, the original function will have to be
re-assigned to said terminal.
Example: If slide switch SW1 is set to ON when function "18 (RS)" has been assigned to input terminal 2 (by terminal setting
"C002"), terminal setting "C002" is changed to "no (no function assigned)," and function "18 (RS)" is assigned to input terminal 1
(by terminal setting "C001").
Even if slide switch SW1 is subsequently returned to OFF, terminal [2] function "C002" and terminal [1] function "C001" will
remain as "no (no function assigned)" and "18 (RS)," respectively.
*4 Function "64 (EMR)" cannot be assigned to input terminal 3 by an operation from the digital operator. The function is
automatically assigned to the terminal when slide switch SW1 is set to ON.
*5 After slide switch SW1 has been set to ON once, function assignments to intelligent input terminals [1] and [3] are not returned to
their original assignments. If necessary, re-assign original functions to the intelligent input terminals.

Note: If the data of an optional operator (SRW or SRW-EX) is copied:
If operator data is copied to your SJ700 series inverter whose slide switch SW1 is ON from another SJ700 series inverter
whose slide switch SW1 is OFF or an SJ300 series inverter, the digital operator on your SJ700 series inverter may display
[R-ERROR COPY ROM] for a moment. This event may occur because the data on intelligent input terminals [1] and [3]
cannot be copied since, on your inverter, exclusive functions have already been assigned to intelligent input terminals [1] and
[3] due to the slide switch SW1 setting to ON. Note that other data is copied. If this event occurs, check the settings on both
copy-source and copy-destination inverters.
(Remark) To reflect the copied data, power off and on again after copy completed.

(Outline of operation)
- S13: Emergency stop button to switch the inverter into safe stop mode and the motor into free-running
status
- S14: Start/stop button
- Switches the inverter into safe stop mode by EMR signal input to a digital input terminal and sets the
motor into free-running status.
(This operation corresponds to EN60204-1 Stop Category 0.)
- Safe stop mode continues as long as the EMR signal is input or until the RS signal is input even after the
EMR signal is canceled.
- To use the inverter for an application in which a mechanical brake (su ch a s for a crane) must be
controlled, the safety output from an external safety relay must be serially connected to the brake
control circuit.
Note: The cables used for safety relay wiring, the EMR signal, and RS signal must be shielded coaxial
cables, such as type RG174/U complying with MIL-C17 (made by LAPP) or KX3B complying with NF
C 93-550. Each cable must be 2.8 mm in outer diameter and 2 m or less in length. The cable shielding
must be grounded.
Note: Every inductor-related device, such as a relay or contactor, must have an overvoltage protection
circuit.

2.2.2 Wiring of the main circuit
(1) Wiring instructions
Before wiring, be sure to confirm that the Charge lamp on the inverter is off.
When the inverter power has been turned on once, a dangero us high voltage remains in the internal
capacitors for some time after power-off, regardless of whether the inverter has been operated.
When rewiring after power-off, always wait 10 minutes or more after power-off, and check with a
multimeter that the residual voltage across terminals P and N is zero to ensure safety during rewiring
work.
1) Main power input terminals (R, S, and T)
- Connect an earth-leakage breaker for circuit (wiring) protection between the power supply and
main power input terminals (R, S, and T).
- Use an earth-leakage breaker with a high rating of a high-frequen cy sensitive current to prevent
the breaker from malfunctioning under the influence of high frequency.
- When the protective function of the inverter operates, a fault or accident may occur in your system.
Therefore, you are recommended to connect a magnetic contactor that interrupts the powe r supply
to the inverter.
- Do not use the magnetic contactor connected to the power input terminal (primary side) or power
output terminal (secondary side) of the inverter to start or stop the inverter.
To start and stop inverter operation by external signals, use only the operation commands (FW and
RV signals) that are input via control circuit terminals.
- This inverter does not support a single-phase power supply but supports only a three-ph ase power
supply.
If you need to use a single-phase power input, contact your supplier or local Hitachi Distributor.
- Do not operate the inverter with an phase loss power input, or it may be damaged.
Since the factory setting of the inverter disables the phase loss input protection, the inverter will
revert to the following status if a phase of power supply input is interrupted:
R or T phase interrupted: The inverter does not operate.
S phase interrupted: The inverter reverts to single-phase operation, and may trip because of
insufficient voltage or overcurrent or be damaged.
Internal capacitors remain charged, even when the power input is under an phase loss condition.
Therefore, touching an internal part may result in electric shock and injury.
When rewiring the main circuit, follow the instructions given in Item (1), "Wiring instructions."
- Carefully note that the internal converter module of the inverter may be damaged if:
- the imbalance of power voltage is 3% or more,
- the power supply capacity is at least 10 times as high as the inverter capacity and 500 kVA or more,
or
- the power voltage changes rapidly.
Example: The above conditions may occur when multiple inverters are connected to each other
by a short bus line or your system includes a phase-advanced capacitor that is turned
on and off during operation.
- Do not turn the inverter power on and off more often than once every 3 minutes.
Otherwise, the inverter may be damaged.
2) Inverter output terminals (U, V, and W)
- Use a cable thicker than the specified applicable cable for the wiring of output terminals to prevent
the output voltage between the inverter and motor dropping. Especially at low frequency output, a
voltage drop due to cable will cause the motor torque to decrease.
- Do not connect a phase-advanced cap acitor or surge absorber on the output side of the inverter. If
connected, the inverter may trip or the phase-advanced capacitor or surge absorber may be
damaged.
- If the cable length between the inverter and motor exceeds 20 m (especially in the case of 400 V
class models), the stray capa citance and inductance of the cable may cause a surge voltage at
motor terminals, resulting in a motor burnout.
A special filter to suppress the surge voltage is available. If you need this filter, contact your
supplier or local Hitachi Distributor.
- When connecting multiple motors to the inverter, connect a thermal relay to the inverter output
circuit for each motor.
- The RC rating of the thermal relay must be 1.1 times as high as t he rated current of the mot or. The
thermal relay may go off too early, depending on the cable length. If this occurs, connect an AC
reactor to the output of the inverter.
Chapter 2 Installation and Wiring
3) DC reactor connection terminals (PD and P)
- Use these terminals to connect the optional DC power factor reactor (DCL).
As the factory setting, terminals P and PD are connected by a jumper. Remove this to connect the
DCL.
- The cable length between the inverter and DCL must be 5 m or less.
Remove the jumper only when connecting the DCL.
If the jumper is removed and the DCL is not connected, power is not supplied to the main circuit
of the inverter, and the inverter cannot operate.
4) External braking resistor connection terminals (P and RB) and regenerative b ra king unit connection
terminals (P and N)
- Inverter models with 22 kW or less capacity have a built-in regenerative braking (BRD) circuit.
If you need increased braking performance, connect an optional external braking resistor to
terminals P and RB.
Do not connect an external braking resistor with resistance less than the specified value. Such a
resistor may cause damage to the regenerative braking (BRD) circuit.
- Inverter models with capacity of 30 kW or more do not have a built-in regenerative braking (BRD)
circuit.
Increasing the braking performance of these models requires an optional regenerative braking unit
and an external braking resistor. Connect the P and N terminals of the optional regenerative
braking unit to the P and N terminals of the inverters.
- The cable length between the inverter and optional regenerative braking unit must be 5 m or less,
and the two cables must be twisted for wiring.
- Do not use these terminals for connecting any devices other than the optional external braking
resistor and regenerative braking unit.
5) Inverter ground terminal (G )
- Be sure to ground the inverter and motor to prevent electric shock.
- According to the Electric Apparatus Engineering Regulations, connect 200 V class models to
grounding electrodes constructed in compliance with type-D grounding (conventional type-III
grounding with ground resistance of 100Ω or less) or the 400 V class models to grounding
electrodes constructed in compliance with type-C grounding (conventional special type-III
grounding with ground resistance of 10Ω or less).
- Use a grounding cable thicker than the specified applicable cable, and make the ground wi ring as
short as possible.
- When grounding multiple inverters, avoid a multi-drop connection of the grounding route and
formation of a ground loop, otherwise the inverter may malfunction.

See Item (4), "Recommended cable gauges, wiring accessories, and crimp terminals."
Note 1: The peripheral equipment described here is applicable when the inverter
connects a standard Hitachi 3-phase, 4-pole squirrel-cage motor.
Power
supply
Note 2: Select breakers that have proper capacity.
(Use breakers that comply with inverters.)
Note 3: Use earth-leakage breakers (ELB) to ensure safety.
Note 4: Use copper electric wire (HIV cable) of which the maximum allowable
temperature of the insulation is 75°C.
Note 5: If the power line exceeds 20 m, cable that is thicker than the specified
applicable cable must be used for the power line.
Note 6: Use a 0.75 mm
2
cable to connect the alarm output contact.
Note 7: Tighten each terminal screw with the specified tightening torque.
Loose terminal screws may cause short circuits and fire.
Tightening a terminal screw with excessive torque may cause damage to the
terminal block or inverter body.
Note 8: Select an earth-leakage breaker (ELB) of which the rated sensitivity current
matches the total length of cables connected between the inverter and power
supply and between the inverter and motor. Do not use a high-speed type ELB
but use a delayed-type ELB because the high-speed type may malfunction.
Note 9: When a CV cable is used for wiring through a metal conduit, the average
current leakage is 30 mA/km.
Note 10: When an IV cable, which has a high relative dielectric constant, is used, the
leakage current is about eight times as high as the standard cable. Therefore,
when using an IV cable, use the ELB of which the rated sensitivity current is
eight times as high as that given in the table below. If the total cable length
exceeds 100 m, use a CV cable.

Name Description
Reactor on input side (for
harmonic control, power
supply coordination, and
power factor improvement)
(ALI-XXX)
Use this reactor to control harmonic waves or when the
imbalance of power supply voltage is 3% or more, when the
power supply capacity is 500 kVA or more, or when the power
voltage may change rapidly. This reactor also improves the
power factor.
Noise filter for inverter
(NF-XXX)
This noise filter reduces the conductive noise that is generated
by the inverter and transmitted in cables. Connect this noise
filter to the primary side (input side) of the inverter.
Radio noise filter
(Zero-phase reactor) (ZCL-X)
The inverter may generate radio noise through power supply
wiring during operation. Use this noise filter to reduce the radio
noise (radiant noise).
Radio noise filter on input side
(Capacitor filter) (CFI-X)
Use this noise filter to reduce the radiant noise radiated from
input cables.
DC reactor (DCL-X-XX)
Use this reactor to control the harmonic waves generated by
the inverter.
Braking resistor
Regenerative braking unit
Use these devices to increase the braking torque of the
inverter for operation in which the inverter turns the connected
load on and off very frequently or decelerates the load running
with a high moment of inertia.
Noise filter on the output side
(ACF-CX)
Connect this noise filter between the inverter and motor to
reduce the radiant noise radiated from cables for the purpose
of reducing the electromagnetic interference with radio and
television reception and preventing malfunctions of measuring
equipment and sensors.
Radio noise filter
(Zero-phase reactor)
(ZCL-XXX)
Use this noise filter to reduce the noise generated on the
output side of the inverter. (This noise filter can be used on
both the input and output sides.)
AC reactor for the output side
For reducing vibrations and
preventing thermal relay
malfunction
(ACL-X-XX)
Using the inverter to drive a general-purpose motor may cause
larger vibrations of the motor when compared with driving it
directly with the commercial power supply. Connect this AC
reactor between the inverter and motor to lessen the pulsation
of motor. Also, connect this AC reactor between the inverter
and motor, when the cable length between them is long (10 m
or more), to prevent thermal relay malfunction due to the
harmonic waves that are generated by the switching operation
on the inverter. Note that the thermal relay can be replaced
with a current sensor to avoid the malfunction.

(5) Connecting the control circuit to a power supply separately from the main circuit
If the protective circuit of the inverter operates to open the magnetic contactor in the input power
supply circuit, the inverter control circuit power is lost, and the alarm signal cannot be retained.
To retain the alarm signal, connect control circuit terminals R0 and T0 to a power supply.
In details, connect the control circuit power supply terminal s R0 and T0 to the primary side of the
magnetic contactor as shown below.

to connect the terminals R0 and T0 (terminal screw size: M4).
- Connect a 3 A fuse in the control circuit power supply line.
- If the control circuit power supply (connected to R0 and T0) is turned on earlier than the main circuit
power supply (connected to R, S, and T), ground fault is not checked at power-on.
- When supplying DC power to the control circuit power supply terminals (R0 and T0), specify "00" as
the "a/b (NO/NC)" selection (function code C031 to C036) for intelligent output terminals ([11] to
[15]) and intelligent relay terminals (AL0, AL1, and AL2). If "01" is specified as the "a/b (NO/NC)"

Chapter 2 Installation and Wiring
2.2.3 Wiring of the control circuit
(1) Wiring instructions
1) Terminals L and CM1 are common to I/O signal s and isolated from each other.
Do not connect these common terminals to each other or ground them.
Do not ground these terminals via any external devices. (Check that the external devices connected
to these terminals are not grounded.)
2) Use a shielded, twisted-pair cable (recommended gauge: 0.75 mm
2
) for connection to control circuit
terminals, and connect the cable insulation to the corresponding common terminal.
3) The length of cables connected to control circuit terminals must be 20 m or less. If the cable length
exceeds 20 m unavoidably, use a VX-compatible controller (RCD-A) (remote operation panel) or
insulated signal converter (CVD-E).
4) Separate the control circuit wiring from the main circuit wiring (power line) and relay control circuit
wiring.
If these wirings intersect with each other unavoidably, square them with each other. Otherwise, the
inverter may malfunction.
5) Twist the cables connected from a thermistor to the thermistor input terminal (TH) and terminal CM1,
and separate the twisted cables from other cables connecte d to other common terminals.
Since very low current flows through the cables connected to the thermistor, separate the cables
from those (power line cables) connected to the main circuit. The length of the cables connected to
the thermistor must be 20 m or less.

6) When connecting a contact to a control ci rcuit terminal (e.g., an intelligent input terminal), use a relay
contact (e.g., crossbar twin contact) in which even a very low current or voltage will not trigger any
contact fault.
7) When connecting a relay to an intelligent output terminal, also connect a surge-absorbing diode in
parallel with the relay.
8) Do not connect analog power supply terminals H and L or interface power supply terminals P24 and
CM1 to each other.
Otherwise, the inverter may fail.

2.2.4 Wiring of the digital operator
- You can operate the inverter with not only the digital operator mounted in the inverter as standard
equipment but also an optional digital operator (OPE-S, OPE-SR, SRW-OJ, or SRW-OEX).
- When you intend to remove the standard digital operator from the inverter and use it as remote
equipment, request your local Hitachi Distributor to supply a connection cable, ICS-1 (1-meter cabl e) or
ICS-3 (3-meter cable).
If you prepare the cable by yourself, the following product is recommended:
HUTP5 PC 4P -X-X: Straight cable equipped with connector at both ends (made by Hitachi Cable, Ltd.)
- The length of the connection cable must be 3 m or less. If a cable over 3 m is used, the inverter may
malfunction.

Chapter 3 Operation
3.1 Operating Methods
WARNING
- While power is supplied to the inverter, do not touch any terminal or internal part of the inverter, check
signals, or connect or disconnect any wire or connector. Otherwise, you run the risk of electric shock
or fire.
- Be sure to close the terminal block cover before turning on the inverter power. Do not open the
terminal block cover while power is being supplied to the inverter o r voltage remains inside. Ot herwise,
you run the risk of electric shock.
- Do not operate switches with wet hands. Otherwise, you run the risk of electric shock.
- While power is supplied to the inverter, do not touc h the terminal of the inverte r, even if it has stopped.
Otherwise, you run the risk of injury or fire.
- If the retry mode has been selected, the inverter will restart suddenly af ter a break in the tripping
status. Stay away from the machine controlled by the inverter when the inverter is under such
circumstances. (Design the machine so that human safety can be ensured, even when the inverter
restarts suddenly.) Otherwise, you run the risk of injury.
- Do not select the retry mode for controlling an elevating or traveling device because output
free-running status occurs in retry mode. Otherwise, you run the risk of injury or damage to the
machine controlled by the inverter .
- If an operation command has been input to the inverter before a short-term power failure, the inverter
may restart operation after the power recovery. If such a restart may put persons in danger, design a
control circuit that disables the inverter from restarting after power recovery. Otherwise, you run the
risk of injury.
- The [STOP] key is effective only when its function is enabled by setting. Prepare an emergency stop
switch separately. Otherwise, you run the risk of injury.
- If an operation command has been input to the inverter before the inverter enters alarm status, the
inverter will restart suddenly when the alarm status is reset. Before resetting the alarm status, make
sure that no operation command has been input.
- While power is supplied to the inverter, do not touch any internal part of the invert er or insert a bar in it.
Otherwise, you run the risk of electric shock or fire.
！
CAUTION
- Do not touch the heat sink, which heats up during the inverter operation. Otherwise, you run the risk of
burn injury.
- The inverter allows you to easily control the speed of motor or machine operations. Before operating
the inverter, confirm the cap acity and ratings of the motor or machine controlled by the inverter.
Otherwise, you run the risk of injury and damage to machine.
- Install an external brake system if needed. Otherwise, you run the risk of injury.
- When using the inverter to operate a standard motor at a frequency of over 60 Hz, check the allowable
motor speeds with the manufacturers of the motor and the machine to be driven and obtain their
consent before starting inverter operation. Otherwise, you run the risk of damage to the motor and
machine and injury
- During inverter operation, check the motor for the direction of rotation, abnormal sound, and
vibrations. Otherwise, you run the risk of damage to the machine driven by the motor.

Chapter 3 Operation
You can operate the inverter in different ways, depending on how to input the operation a nd
frequency-setting commands as described below.
This section describes the features of operating methods and the items required for operation.
(1) Entering operation and frequency-setting commands from the digital operator
This operating method allows you to operate the inverter through key operations on the stand ard
digital operator mounted in the inverter or an optional digital operat or.
When operating the inverter with a digital operator alone, you need not wire the control circuit
terminals.
(Items required for operation)
1) Optional digital operator (not required when you use the standard digital ope rator)
Digital operator
(2) Entering operation and frequency-setting commands via control circuit terminals
This operating method allows you to operate the inverter via the input of operation signals from
external devices (e.g., frequency-setting circuit and start switch) to control circuit terminals.
The inverter starts operation when the input power supply is turned on and then an operation
command signal (FW or RV) is turned on.
You can select the frequency-setting method (setting by voltage specification or current specification)
through the input to a control circuit terminal according to your system. For details, see Item (2),
"Explanation of control circuit terminals," in Section 2.2.1 (on pages 2-7 and 2-8).
(Items required for operation)
1) Operation command input device: External switch or relay
2) Frequency-setting command input device: External device to input signals (0 to 10 VDC, -10 to +10
VDC, or 4 to 20 mA)

The stop mode selection function allows you to select one of
two methods of stopping the motor when a stop command is
input from the digital operator or via the control circuit terminal
block. One is to decelerate the motor according to the specified
deceleration time and then stop it; the other is to let the motor
run freely until it stops.
If a start command is input while the motor is in free-running status, the inverter will restart the motor
according to the setting of the restart mode after FRS (b088). (See Section 4.2.47.)

to the motor ratings.
- The base frequency is the nominal frequency of the motor.
Set a base frequency that meets the motor specification.
Carefully note that setting the base frequency to less than
50 Hz may result in motor burnout.
- A special motor requires a base frequency of 60 Hz or
more. Your inverter model may not be suitable for such a
special motor, and one with a larger capacity may be
required.
- Select the motor voltage that meets the motor specification.
Selecting a motor voltage exceeding the motor specification
may result in motor burnout.
- To switch the base frequency among the 1st, 2nd, and 3rd settings, assign function "08" (SET) and "17"

and decreases the energy regenerated on the inverter, which results in a shorter deceleration time.
4.2.10 Maximum frequency setting
The maximum frequency setting function allows you to set the
maximum frequency of the motor driven by the inverter.
The maximum frequency set here corresponds to the maximum level
of each external analog input (See Section 4.2.12) (for example, 10 V
of the input of 0 to 10 V).
To switch the maximum frequency among the 1st, 2nd, and 3rd
settings, assign function "08" (SET) and "17" (SET3) to intelligent
input terminals. Use the SET and SET3 signals for switching.

You can use this filter function effectively for removing noise from the frequency-setting circuit signal.
If the noise disables the stable operation of the inverter, increase the setting. Setting a larger value makes
the inverter response slower. The filtering constant is "set value (1 to 30) x 2 ms."

Since all free V/f frequencies are set to 0 Hz as default (factory setting), specify their arbitrary values
(begin setting with free-setting V/f frequency (7)). (The inverter cannot operate with the free V/f
characteristic in the factory setting.)
Enabling the free V/f characteristic setting function disables the torque boost selection (A041/A241), base
frequency setting (A003/A203/A303), and maximum frequency setting (A004/A204/A304). (The inverter
assumes the value of free-setting V/f frequency (7) as the maximum frequency.)

The inverter outputs the voltage according to the settings of the manual torque boost (A042/A242/A342)
and manual torque boost frequency adjustment (A043/A243/A343).
Use the manual torque boost value (A042/A242/A342) to specify the rate of the boost to the voltage
(100%) set by the AVR voltage select.
The set rate of voltage corresponds to the boost voltage that is output when the output frequency is 0 Hz.
When increasing the value of the manual torque boost value, be careful to prevent motor over-excitation.
Over-excitation may result in motor burnout.
Use the manual torque boost frequency adjustment (A043/A243/A343) to specify the rate of the freque ncy

When automatic torque boost (data "01") is selected by the torque boost selection (A041/A241), the
inverter automatically adjusts the output frequency and voltage according to the load on the m otor.
(During actual operation, the automatic torque boost is usually combined with the manual torque boost.)
When you select the automatic torque boost, adjust the settings of the motor capacity selection
(H003/H203) and motor pole selection (H004/H204) according to the motor to be driven.
If the inverter trips due to overcurrent during motor deceleration, set the AVR function select (A081) to
always enable the AVR function (data "00").

The DC braking function allows you to apply DC braking to the
motor according to the load on the motor.
You can control DC braking in two ways: the external control
through signal input to intelligent input terminals and the internal
control to be performed automatically when the motor is started
and stopped.
Note that the motor cannot be stopped by DC braking if the load
on the motor produces a large moment of inertia.

(3) Internal DC braking (A051: 01)
You can apply DC braking to the motor even without entering braking signals via the DB terminal when the
inverter starts and stops. To use the internal DC braking function, specify "01" for the DC braking enable
(A051).
Use function "A057" to set the DC braking force for starting, and use function "A058" to specify the DC
braking time for starting, regardless of the braking mode selection (edge or level mode ). (See examples
4-a and 4-b.)
Set the braking force for periods other than starting by using the DC braking force setting (A054).
Set the output frequency at which to start DC braking by using the DC braking frequency setting (A052).
When you set the DC braking wait time (A053), the inverter output will be shut off when the output
frequency reaches the setting of "A052" after the operation command (FW signal) is turn ed off, and the
motor will run freely for the delay time set by "A053". DC braking will be started after the delay (A053).
The internal DC braking operation to be performed when the operation com mand is switched from the stop
command to the start command varies depending on the braking mode (edge or level mode).
Edge mode: The DC braking time setting (A055) is given priority over operation commands, and the
inverter performs DC braking according to the setting of "A055". When the output frequency
reaches the setting of "A052" the inverter performs DC braking for the time set for "A055".
Even if the stop command is input during DC braking, DC braking continues until the time
set for "A055" elapses. (See examples 5-a and 6-a.)
Level mode: Operation commands are given priority over the DC braking time setting. The inverter
follows operation commands, regardless of the DC braking time setting (A055). If the start
command is input during DC braking, the inverter starts the normal motor operation,
regardless of the DC braking time setting (A055). (See examples 5-b and 6-b.)

(4) Internal DC braking (triggered only when the output frequency reaches a set frequency) (A051: 02)
You can also operate the internal DC braking function so that DC braking is applied to the motor when the
inverter output frequency falls to the DC braking frequency setting (A052) or below.
When the internal DC braking function is used in this mode, the external DC braking described in Item (2)
and the internal DC braking described in Item (3) cannot be used.
In this mode, DC braking operates only when the operation command signal is on (i.e., the start command
is input).
The inverter starts DC braking when both the frequency set by the frequency command and the current
output frequency fall to the DC braking frequency setting (A052) or below. (See example 7-a.)
When the frequency set by the frequency command increases to the "setting of 'A052' + 2 Hz" or more, the
inverter stops DC braking and restores its normal output. (See example 7-a.)
If the frequency set by the frequency command is 0 Hz when the start command is input via an analog
input terminal, the inverter will start operation with DC braking because both the frequency set by the
frequency command and current output frequency are 0 Hz. (See example 7-b.)
If the operation command signal (start command) is turned on when the frequency command specifies a
frequency larger than the DC braking frequency (A052), the inverter will start operation with the normal
output.
(Example 7-a) (Example 7-b)

This function restricts the input of frequency commands that
specify any frequencies outside the upper and lower l imits.
Always set the upper limit before setting the lower limit. Also, be sure to keep the frequency upper limit
(A061/A261) larger than the frequency lower limit (A062/A262).
Be sure that upper limit/lower limit does not exceed Maximum frequency (A004/A204/A304).
Be sure to set output frequency (F001) and multiple speed 1 to 15 (A021 to A035) in between uppelimit

The jump frequency function allows you to operate the inverter so
that it avoids the resonant frequency of the machine driven by the

Since the inverter avoids the motor operation with a constant output
frequency within the specified range of the frequencies to jump when
the jump frequency function is enabled, you cannot set any inverter
output frequency within the specified range of the frequencies to
jump.
Note that, while the inverter is accelerating or decelerating the motor, the inverter output frequency

You can disable the PID function with an external signal during
the PID operation. For this purpose, assign function "23" (PID

Turning the PID terminal on disables the PID function and makes
the inverter perform the normal output.

(3) PV source setting
Select the terminal to be used for the feedback signal with the PV source setting function (A076).
The terminal to input the target value follows the frequency source setting (A001). The terminal selected by
the PV source setting (A076) is excluded.
If the control circuit terminal block ("01") has been specified for frequency source setting "A001", the
setting of AT selection (A 005) is invalid.
The table below shows how the PID target value is selected according to the setting of "A006" when the
analog input is selected by the PV source setting and the control circuit terminal block ("01") i s specified for
"A001".

Chapter 4 Explanation of Functions
When you specify the 02 RS485 communication for the PV source setting (A076), transfer data as
described below .
1) When the ASCII mode is selected (C078 = 00)
Use the 01 command for data transfer. To transfer feedback data, set the mo st-significant byte of
frequency data to "1".
Example: When transmitting the frequency data specifying 5 Hz
The data to be transmitted consists of six bytes, indicating a value 100 times as large as
the set frequency value. → "000500"
Change the most-significant byte to "1". → "100500"
Convert the data to ASCII format. → "31 30 30 35 30 30"
Note: In ASCII mode, the unit of setting is always frequency (Hz).
2) When the Modbus RTU mode is selected (C078 = 01)
Write the setting data (on the assum ption that "10000" indicates 100%) to register address 0006h.

Note: This register is readable and writable. However, this register can be read only when Modbus
RTU has been specified as the communication mode for PID feedback. It cannot be read with
other settings.
- When pulse train input is specified for PID feedback, the input pulse train frequency (Hz) is converted to a
percentage (with maximum frequency corresponding to 100%) and fetched as the feedback.
For the pulse train input frequency, see Section 4.3.21.
(4) Feed forward selection
- Select the terminal to be used for the feed forward signal through PID feed forward selection (A079).
- Even if the terminal selected for the target or feedback data is also selected for the terminal by A079, the
terminal functions according to the setting of A079.
- Specifying the value to disable selection for A079 disables feed forward control.
(5) Output of inverted PID deviation
Some sensor characteristics may cause the polarity of the deviation of feedback dat a from the target value
to be inconsistent with the inverter operation command. If the inconsistency occurs, specify "01" for
function "A077" to invert the polarity of the deviation.
Example: When controlling the compressor for a refrigerator
Assume that the temperature and voltage specifications of the temperature sensor are -20°C to +100°C
and 0 to 10 V and the target value is 0°C.
If the current temperature is 10°C and the inverter is under the normal type of PID control, the inverter will
reduces the output frequency because the feedback data is larger than the target value.
→ In such a case, specify "01" for function "A077" to invert the feedback deviation. Then, the inverter will
increase the output frequency.

You can limit the PID output to within a specific range with reference to the target value.
To use the PID variation limit function, set the PID variation range (A078).
(Set a value on the assumption that the maximum frequency corresponds to 100%.)
The variation of PID output is limited within ±"value of A078" from the target value.
(Setting "0.0" for the PID variation range [A078] disables the PID variation limit function.)
This function is deactivated when 0.0 is set on A078.

(7) Output of inverted PID deviation
If the inverter is under the normal PID control and the PID operation result is a negative value, the
frequency command to the inverter will be limited to 0 Hz. However, when "02" (enablin g the inverted
output) is set for the PID Function Enable (A071), the PID operation result to be output to the inverter is
inverted if the result is a negative value.
Setting "02" for function "A071" disables the PID variation limit (A078) described above.
(8) PID gain adjustment
If the inverter response is unsteady when the PID control function is used, try to adjust gain settings as
follows:
- If the feedback data does not quickly follow the change in the target value → Increase the P gain (A072).
- If the feedback data is unstable although it quickly follows the change in the target value → Reduce the
P gain (A072).
- If considerable time is required until the feedback data matches the target value → Reduce the I gain
(A073).
- If the feedback data fluctuates unsteadily → Increase the I gain (A073).
- If the inverter response is slow even after the P gain is increased → Increase the D gain (A074 ).
- If the feedback data becomes fluctuant and unsteady when the P gain is increased → Reduce the D gain
(A074).
(9) Maximum PID deviation output (OD)
You can set the PID deviation level (C044) for PID control. When the PID deviation (ε) exceeds the level
set as the level "C044", the signal is output to an intelligent output terminal.
A value from 0 to 100 can be set as the level "C044". The range of values corresponds to the range of
target values from 0 to the maximum.
To use this output function, assign function "04" (OD) to one of the terminal functions C021 to C025 or the
alarm relay terminal function C026.
(10) Feedback comparison signal
A feedback comparison signal can be output to an intelligent output terminal when the PID feedback data
exceeds the specified range.
To use this signal output function, assign function "31" (FBV) to one of the termina l functions C0 21 to C025
or the alarm relay terminal function C026.

You can monitor the PID feedback data on the inverter.
When you set a PV scale conversion with function "A075", the value to be displayed as the monitored data
can be the product of the feedback data and the scale.
"Monitored value" = "feedback data (%)" x " PV scale conversion (A075)"
(12) Reset of PID integration (PIDC)
This reset function clears the integral result of PID operation.
To use this function, assign function "24" (PIDC) to one of the terminal functions C001 to C008.
The integral result is cleared each time the PIDC terminal is turned on.
Never turn on the PIDC terminal during the PID operation. Otherwise, the inverter may trip because of
overcurrent. Be sure to disable the PID function before turning on the PIDC terminal.

Select one of the following three methods of changing the
acceleration or deceleration time:
1) Changing the time by the signal input to an intelligent input
terminal
2) Automatically changing the time when the output frequency
reaches a specified frequency
3) Automatically changing the time only when switching the
motor operation from forward rotation to reverse rotation, or
vice versa
Selecting the 3rd control system enables the change of the
acceleration or deceleration time only by terminal input. Not bytwo-stage acceleration/deceleration
frequency.
To change the acceleration/deceleration time by the signal input to an intelligent input terminal, assign

Use functions "A097" and "A098" to select acceleration and
deceleration patterns, respectively.
You can individually set an acceleration pattern for acceleration and a deceleration patte rn for
deceleration.
When the acceleration/deceleration pattern is set other than 00 (linear) using analog inp ut as frequency

(2) Curve constant (swelling degree)
Specify the swelling degree of the acceleration curve with reference to the following graphs:
4 - 32
The acceleration or deceleration time may be shortened midway through the acceleration or deceleration
according to the S-curve pattern.
If the LAD cancellation (LAC) function has been assigned to an intelligent input terminal and the LAC
terminal is turned on, the selected acceleration and deceleration patterns are ignored, and the output
frequency is quickly adjusted to that specified by the frequency command.
(3) Curvature of EL-S-curve pattern
When using the EL-S-curve pattern, you can set the curvatures (A150 to A153) individually for
acceleration and deceleration.
If all curvatures are set to 50%, the EL-S-curve pattern will be equivalent to the S-curve pattern.
4.2.26 Energy-saver operation
The energy-saver operation function allows you to automatically minimize
the inverter output power while the inverter is driving the motor at
constant speed. This function is suited to operating a fan, pump, or other
load that has a reduced-torque characteristic.
To use this function, specify "01" for the operation mode selection (A085).
Use the energy saving mode tuning function (A086) to adjust the response and accuracy of the
energy-saver operation.
The energy-saver operation function controls the inverter operation comparatively slowly. Therefore, if a
sudden change in the load occurs (e.g., impact load is applied), the motor may stall, and, cons equently,
the inverter may trip because of overcurrent.

(1) Retry (restart) after instantaneous power failure
You can select tripping or retrying (restarting) the motor
operation as the inverter operation to be performed at the
occurrence of instantaneous power failure or undervoltage.
If you specify a retry operation for the selection of restart mode
(b001), the inverter will retry the motor operation for the number
of times set as "b005" after an instantaneous po wer failure or
the number of times set as "b009" after overvoltage
respectively, and then trip if all retries fail. (The inverter will not
trip if you specify an unlimited number of retries.)
With function "b004" you can select whether to make the inverter trip when an instantaneous power failure
or undervoltage occur while the inverter is in a stopped state.
When selecting a retry operation, also set the retry conditions listed below according to the system to be
driven by the inverter.
Even during a retry operation, the inverter will trip with error code "E09" (undervoltage ) displayed if the
undervoltage status continues for 40 seconds.

*1 If the inverter trips because of overvoltage or overcurrent while decelerating the motor, the inverter will
display error code "E16" (instantaneous powe r failure), and the motor will start free-running. If this
error occurs, prolong the deceleration time.
*2 If a DC voltage (P-N) is supplied to control power supply terminals R0 and T0, the inverter may detect
undervoltage and trip when the inverter power is turned off. If this cause a problem in your system,
specify "00" or "02" for the trip selection.
*3 The inverter may start the motor with 0 Hz if:
1) the output frequency is not more than half the base frequency or
2) the voltage induced on the motor is attenuated quickly.
*4 Even when a retry operation (01 to 03)is specified for the selection of restart mode (b001) and
"disabling tripping" (00 or 02) is specified for the selection of a trip after instantaneous power failure or
undervoltage in the stopped state, the inverter will trip if the instanta neous power failure continues over
the allowable under-voltage power failure time. (See example 2.)
*5 Even when a retry operation is specified for the trip selection, the inverter will trip if the cause of trip is
not removed by the end of the retry wait time before motor restart (b003). If this occurs, prolong the
retry wait time.
*6 Even when a retry operation is specified for the retry selection, the inverter will trip if the undervoltage
status continues for 40 seconds or more.
*7 when starting the motor with matching frequency is selected, inverter may restart suddenly by alarm
resetting, resetting and retry-start.

(3) Restarting methods
- Restart with matching frequency
The inverter detects the frequency and rotation direction based on the residual voltage in the motor,
and then restarts the motor based on the detected frequency.
- Restart with input frequency
The inverter starts the output with the frequency specified for the start frequency selection (b030),
searches for the point where the frequency and voltage are balanced while keeping the current at
the restart current level (b028), and then restarts the motor.
If the inverter trips when it restarts the motor in this way, reduce the setting of "b028".
- After the inverter output has been shut off, the digital operator continues to display until
the inverter restarts the motor operation.

01 Enabling the protection
An phase loss power input may cause the following conditions, resulting in an inverter failure:
(1) The ripple current increases in the main capacitor, and the cap acit or life will be shortened significantly.
(2) When the inverter is connected to a load, the internal converter or thyristor of the inverter may be
damaged.

Chapter 4 Explanation of Functions
4.2.29 Electronic thermal protection
The electronic thermal protection function allows you to protect
the motor against overheating. Make settings of this function
based on the rated current of the motor. The inverter will trip for
overheat protection according to the settings.
This function provides optimum overheat protection that is also
designed with the lowering of the motor's cooling performance
at low speeds in mind.

Rated current: 64 A
Range of setting: 12.8 A (20%) to 64.0 A (100%)
When 64 A is set as the electronic thermal setting (b012),
the time-limit characteristic is as shown on the right.
(2) Electronic thermal characteristic
The frequency characteristic set as the electronic thermal characteristic is integrated with the value of
"b012", "b212", or "b312".
The cooling-fan performance of a general-purpose motor lowers when the motor speed is low. So load
(current) is decreased.
The reduced-torque characteristic is designed to match the heat generation by Hit achi's general-purpose
motors.
