2.1 Installation
CAUTION
！
- Install the inverter on a non-flammable surface, e.g., metal. Otherwise, you run the risk of fire.
- Do not place flammable materials near the installed inverter. Otherwise, you run the risk of fire.
- When carrying the inverter, do not hold its top cover. Otherwise, you run the risk of injury by dropping
the inverter.
- Prevent foreign matter (e.g., cut pieces of wire, sputtering welding materials, iron chips, wire, and
dust) from entering the inverter. Otherwise, you run the risk of fire.
- Install the inverter on a structure able to bear the weight specified in this Instruction Manual.
Otherwise, you run the risk of injury due to the inverter falling.
- Install the inverter on a vertical wall that is free of vibrations. Otherwise, you run the risk of injury due
to the inverter falling.
- Do not install and operate the inverter if it is damaged or its parts are missing. Otherwise, you run the
risk of injury.
- Install the inverter in a well-ventilated indoor site not exposed to direct sunlight. Avoid places where
the inverter is exposed to high temperature, high humidity, condensation, dust, explosive gases,
corrosive gases, flammable gases, grinding fluid mist, or salt water. Otherwise, you run the risk of fire.
- The inverter is precision equipment. Do not allow it to fall or be subject to high impacts, step on it, or
place a heavy load on it. Doing so may cause the inverter to fail.

Chapter 2 Installation and Wiring
A
2.1.1 Precautions for installation
(1) Transportation
The inverter uses plastic parts. When carrying the inverter, 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 parts 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 inverter. In particular, keep sufficient distance between the inverter
and other heat sources (e.g., braking resistors and reactors) if they are installed in the vicinity.

5 cm or more 5 cm or more
(*2)
(3) Ambient temperature
Avoid installing the inverter in a place where the ambient temperature goes above or below the
allowable range (-10°C to +40°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 condensation.
Condensation inside the inverter will result in short circuits and malfunctioning of electronic parts. 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.
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.

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
Heat in the inverter rises from the under to the upper part of the inverter up with the fan built into the
inverter, and make it to the one without the obstacle even if the influence of heat is received, please
when you arrange apparatus up.
Moreover, please usually arrange it sideways like the left side of the figure below when you store two or
more inverters in the same enclosure.
The temperature in an upper inverter rises because of the heat of a lower inverter when it places one
behind another unavoidably to reduce the space of the enclosure, it causes the inverter breakdown,
and set it up, please so that the heat of a lower inverter should not influence an upper inverter.
Please note it enough as ventilation, ventilation, and the size of the board are enlarged so that the
ambient temperature of the inverter should not exceed the permissible value when two or more
inverters are stored on the enclosure.
(8) 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.

(9) 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 with the heat sink positioned outside, cut out the enclosure panel
according to the specified cutting dimensions.
The cooling section (including the heat sink) 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.

2.2.2 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 dangerous 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-frequency 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 power 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-phase 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 capacitor 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 capacitance 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.
2 - 11
Chapter 2 Installation and Wiring
- 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 the rated current of the motor. 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.
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 braking unit connection
terminals (P and N)
- Inverter models with 30 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 37 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 wiring 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.

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.
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.
The inverter may generate radio noise through power supply
wiring during operation. Use this noise filter to reduce the radio
noise (radiant noise).
Use this noise filter to reduce the radiant noise radiated from
input cables.
Use this reactor to control the harmonic waves generated by
the inverter.
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.
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.
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.)
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.
This filter converts the inverter output into a sinusoidal
waveform.

Chapter 2 Installation and Wiring
Note the following when connecting separate power supplies to control circuit power supply terminals
(R0 and T0) and main circuit power supply terminals (R, S, and T):
- Use a cable thicker than 1.25 mm
- Connect a 3 A fuse in the control circuit power supply line.( Tightening torque:1.2Nm,max
torque:1.4Nm)
- 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)"
selection, output signals may chatter when the DC power supply is shut off.

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 signals 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
terminals, and connect the cable insulation to the corresponding common terminal. (Tightening
torque:0.7Nm,max torque:0.8Nm)
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 (CVD-E) insulated signal converter.
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 connected 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 circuit 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 cable) 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.

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 or voltage remains inside. Otherwise,
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 touch the terminal of the inverter, 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 after 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 inverter 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 capacity 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 and
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 standard
digital operator mounted in the inverter or an optional digital operator.
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 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)

4.1.7 Scaled output frequency monitoring
When the scaled output frequency monitoring (d007) is selected, the
inverter displays the gain data converted from the output frequency
with the frequency scaling conversion factor (b086).
Use this function, for example, to change the unit of a value (e.g., motor speed) on display.
Value displayed by function "d007" = "output frequency monitor(d001)" x "frequency scaling conversion
factor (b086)"
The frequency scaling conversion factor (b086) can be set within the range 0.1 to 99.9 in steps of 0.1.
(Example) Displaying the speed of a 4-pole motor
Speed N (min
-1
) = (120 x f [Hz])/pole = f (Hz) x 30
As the result of the above calculation with the factor (b086) set to 30.0, the inverter displays "1800" (60
x 30.0) when the output frequency is 60 Hz.
(Display)
0.00 to 99.99 in steps of 0.01
100.0 to 999.9 in steps of 0.1
1000. to 9999. in steps of 1
1000 to 3996 in units of 10
Note: When you have selected the digital operator as the device to input frequency-setting commands,
you can change the output frequency setting by using the △ and/or ▽ key (only while the inverter
is operating the motor).
- The change in output frequency made in this mode can be reflected in the frequency setting
(function "F001"). Press the STR key to write the new frequency over the currently selected
frequency setting. (The precision of the storable frequency data depends on the frequency
setting.)
- You cannot change the output frequency while the PID function is enabled or the inverter is not
operating the motor.

4.2.13 Frequency addition function
The frequency addition function allows you to add or subtract the
value specified as the frequency to be added (A145) to or from the
frequency value of a selected frequency command.
A145: Frequency to be added
A146: Sign of the frequency to be added
C001 to C008: Terminal [1] to [8]functions

To use this function, assign function "50" (ADD) to an intelligent input terminal.
When the ADD terminal is turned on, the inverter performs the addition or subtraction of the value specified
as "A145".

Note 1: If the sign of the frequency value in the frequency command changes from minus (-) to plus (+), or
vice versa, as the result of frequency addition, the motor operation direction will be inverted.
Note 2: When the PID function is used, the frequency addition function can apply to PID target data. (In
such cases, the data display by function "A145" is in percentage [in steps of 0.01%]).

4.2.15 External analog input (O/OI/O2) filter setting
The external analog input filter setting function allows you to set the
input-voltage/input-current sampling time to be applied when frequency
commands are input as external analog signals.
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."
When the setting is "31" (factory setting), a hysteresis of ±0.1 Hz is added to the filtering constant (500
ms).

within the output frequency range of 0 to 60 Hz.

(3) Free V/f characteristic setting
The free V/f characteristic setting function allows you to set an arbitrary V/f characteristic by specifying the
voltages and frequencies (b100 to b113) for the seven points on the V/f characteristic curve.
The free V/f frequencies (1 to 7) set by this function must always be in the collating sequence of "1 ≤ 2 ≤ 3
≤ 4 ≤ 5 ≤ 6 ≤ 7".
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.)

(1) Automatic torque boost
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 frequency
at each breakpoint to the base frequency (100%).
To switch the settings among the 1st, 2nd, and 3rd settings ("A041 to A043", "A241 to A243", and "A342
and A343"), assign function "08" (SET) and "17" (SET3) to intelligent input terminals. Use the SET and
SET3 signals for switching.

(2) Automatic torque boost
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 motor.
(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").
If you cannot obtain the desired operation characteristic by using the automatic torque boost, make the
following adjustments:

4.2.19 DC braking (DB) setting
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.

Internal DC braking is enabled. (The braking
operates only with the set braking frequency.)
With internal DC braking enabled, DC braking is
started when the output frequency reaches the
set braking frequency.
The DC braking wait time specifies the delay in
starting DC braking after the set braking time has
elapsed or the DB terminal has been turned on.
"0" specifies the smallest force (zero current);
"100" specifies the largest force (rated current).
This setting is valid for the external DC braking in
edge mode or for the internal DC braking.
This setting is valid for the internal DC braking.
DC braking is started when the motor-start
command is input.

(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 turned 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 command 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.)

Chapter 4 Explanation of Functions
(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.
Please do not use external DC braking by ON/OFF of DB terminal when you select this function.
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.

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

4.2.23 PID function
The PID function allows you to use the inverter for the process
control on fluid flow, airflow, and pressure.
To enable this function, specify "01 lenabled" or "02 inverted data
output enabled" for function "A071".
You can disable the PID function with an external signal during
the PID operation. For this purpose, assign function "23" (PID
terminal: disabling PID operation) to an intelligent input terminal.
Turning the PID terminal on disables the PID function and makes
the inverter perform the normal output.
With the PID function, you can limit the PID output according to
various conditions.
Refer to maximum frequency (4.2.10), frequency limiter (4.2.20),

Chapter 4 Explanation of Functions
A
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 most-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 assumption 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 data 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.

(6) Limitation on PID variation range
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.

Chapter 4 Explanation of Functions
(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" (enabling 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 terminal functions C021 to C025
or the alarm relay terminal function C026.

(11) Process variable (PV), PID feedback monitoring (d004)
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.

4.2.24 Two-stage acceleration/deceleration function (2CH)
The two-stage acceleration/deceleration function allows you to
change the acceleration or deceleration time while the inverter is

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

The acceleration or deceleration time may be shortened midway through the acceleration or deceleration

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, consequently,
the inverter may trip because of overcurrent.

4.2.27 Retry or trip after instantaneous power failure
(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 power 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.

Description
Chapter 4 Explanation of Functions
*1 If the inverter trips because of overvoltage or overcurrent while decelerating the motor, the inverter will
display error code "E16" (instantaneous power 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 instantaneous 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.
The figures below show the timing charts for starting with a matching frequency (when "02" is specified for
the selection of restart mode [b001]).

(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.

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.
You can configure this function so that the inverter outputs a
warning signal before it trips for electronic thermal protection.
