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.
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 left 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.

3. Operation
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.
- 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.

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
2-2
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.
(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 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.

(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) 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.
Position of ventilation fan
(8) Mounting in an enclosure
The internal fan releases the heat generated by the inverter from the upper part of the inverter. When it is
necessary to install a device above the inverter, please ensure that the device is protected against this heat.
When several inverters are mounted in the same cabinet the standard arrangement of the inverters is side-by-side
with certain space as shown in the figure on the left below. If the inverters must be mounted one above the other
in order to save the cabinet space or similar, the heat from the lower inverter may lead to temperature rise and
breakdown of the higher inverter. Please ensure that the heat generated by the lower inverter does not affect the
one above by installing a mechanical separation or similar (e.g. guide plate between the inverters as shown in the
figure below right).
When mounting several inverters in the same cabinet, design the cabinet so that the temperature inside the
cabinet does not exceed the allowable specific range for the inverter (by using increased ventilation and/or
enlarging the size of cabinet etc.)

(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 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 left 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.

About the emergency stop function (disabled by the factory setting)
- 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.
- When the emergency stop function is enabled, intelligent input terminals 1 and 3 are used exclusively for 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 switch 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.

*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 (WOP, 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.
Note: Slide Switch 12
Some models have slide switch in the position as shown below. Default setting of this switch is at "ON"
position.
Please don't change the setting. If it is changed, inverter may trip and disabled to run.

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 turned 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.
(note) As for the 5.5kW and 7.5kW inverters, the washer on the main terminal screw (R, S, T, PD, P, N, U, V, W, RB)
has two cutouts. Since those cutouts are to avoid the cable fixing portion of crimp terminal goes under the
washer, it should be fixed in direction with those two cutouts in line with cable as described below.
Otherwise, you run the risk of loose connection and fire.
1) Main power input terminals (R, S, and T)
- Install 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 have occurred 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 input but supports only a three-phase input.
If you need to use a single-phase power input, contact your supplier or local Hitachi Distributor.
- Do not operate the inverter when an input phase is lost (input phase loss), otherwise the inverter may be
damaged. Since the factory setting of the inverter disables the phase loss input protection, the inverter will go
into the following status if a phase of power supply input is interrupted and not supplied to the inverter:
R or T phase interrupted: The inverter does not power up.
S phase interrupted: The inverter goes into 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 a 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.
washer of the terminal screw
Chapter 2 Installation and Wiring
2-12
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.
- 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 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 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.

(3) Applicable peripheral equipment
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.
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 mm2 cable to connect the alarm output contact.
Note 7: T ighten 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 (ELCB) 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.
LCR filter
Connect this noise filter between the inverter and motor to convert the
inverter output into a sinusoidal waveform and to reduce the motor
vibration, motor noise and the radiant noise radiated from cables.

(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
terminals R0 and T0 to the primary side of the magnetic contactor as shown below.
(Connection method)
Power-receiving specifications
200 V class model:
200 to 240 V (+10%, -15%)
(50/60 Hz ±5%), (282 to 339 VDC)
400 V class model:
380 to 480 V (+10%, -15%)
(50/60 Hz ±5%), (537 to 678 VDC)
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 mm2 to connect the terminals R0 and T0 (terminal screw size: M4).
- Connect a 3A 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.
2. Remove the J51 connector.
1. Remove the connected cables.
3. Connect the control circuit power
supply cables to the control circuit
power supply terminal block.
J51
Chapter 2 Installation and Wiring
2-20
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 mm2) for connection to control circuit 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, you should use UP/DOWN function or current signal input with an isolation amplifier.
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.

(3) Switching the input control logic
- In the factory setting, the input control logic for terminal FW and intelligent input terminals is the sink logic.
To switch the input control logic to the source logic, remove the jumper connecting terminals P24 and PLC on the
control circuit block, and then connect terminals PLC and CM1 with the jumper.

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, WOP).
- 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:
NETSTAR-C5E PC 24AWGx4P LBH: Straight cable equipped with connector at both ends (made by Hitachi Metal, 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
3-2
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)
*) 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. (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)
(3) Entering operation and frequency-setting commands; both from a digital operator and via control circuit terminals
This operating method allows you to arbitrarily select the digital operator or control circuit terminals as the means
to input operation commands and frequency-setting commands. (Items required for operation)
1) See the items required for the above two operating methods.
(4) Operation by Easy sequence function (Drive programming function)
The inverter can be operated by downloading the user's program made with the dedicated PC software,
ProDriveNext. Please refer to “Easy sequence function” for details.
(5) Operation via communication
The inverter can be operated by an external communication device via Modbus-RTU or ASCII protocol (Hitachi
protocol) through the TM2 terminal on the control terminal l board. Please refer to “Communication function” for
details.

3.2.2 Code display system and key operations
This section describes typical examples of digital operator operation (in basic and full display modes) and an example
of special digital operator operation in extended function mode U.
The initial display on the monitor screen after power-on depends on the setting of function "b038". For details,
see Section 4.2.85, "Initial-screen selection," (on page 4-78).
When the setting of function "b038" is "01" (factory setting), the monitor initially shows as the
setting of function "d001" (output frequency monitoring). Pressing the key in this status changes the
display to .
Note: The display contents on the monitor depend on the settings of functions "b037" (function code display
restriction), "b038" (initial-screen selection), and "b039" (automatic setting of user parameters).
For details, see Sections 4.2.84, "Function code display restriction," (on page 4-76), 4.2.85 and "Initial-screen
selection," (on page 4-78).

3.5 Basic Parameter Setting to Drive Motor
3.5.1 Setting Frequency command source and Run command source
This section describes how to drive the motor with SJ700D briefly.
The frequency and run command are necessary to drive the motor with the inverter.
In many cases, these sources are set as below;
Setting the frequency : (A) Data settings (Digital operator)
(B) Via external analog signals (Control terminal)
Run and stop : (A) RUN / STOP key (Digital operator)
(B) Via external signal (Control terminal)
The frequency command and Run command sources can be changed by the parameter A001 (Frequency command
source) and A002 (Run command source) respectively.
In addition to the basic setting mentioned above, there are several options for A001 and A002 setting.

(C) Multi-speed selection – Binary operation
The inverter can store several target frequencies (up to 16), which is useful to define such low / middle / high
frequencies and those frequencies are switched by external signals. The actual target frequency is selected from
those pre-set frequencies in accordance with the signal status of the multi speed inputs. This part describes an
example using 3 frequency sets.

4.1.5 Intelligent input terminal status
When the intelligent input terminal status function (d005) is selected, the
inverter displays the states of the inputs to the intelligent input terminals.
The internal CPU of the inverter checks each intelligent input for significance, and the inverter displays active inputs
as those in the ON state. (*1)
Intelligent input terminal status is independent of the a/b contact selection for the intelligent input terminals.
(Example)
FW terminal and intelligent input terminals [7], [2], and [1]: ON
Intelligent input terminals [8], [6], [5], [4], and [3]: OFF
(*1)When input terminal response time is set, terminal recognition is delayed. (refer 4.2.79)
4.1.6 Intelligent output terminal status
When the intelligent output terminal status function (d006) is selected, the
inverter displays the states of the outputs from the intelligent output terminals.
This function does not monitor the states of the control circuit terminals but monitors those of the outputs from the
internal CPU.
Intelligent input terminal status is independent of the a/b contact selection for the intelligent input terminals.
(Example)
Intelligent output terminals [12] and [11]: ON
Alarm relay terminal AL and intelligent output terminals [15] to [13]: OFF
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 Function Mode
4.2.1 Output frequency setting
The output frequency setting function allows you to set the inverter output
frequency.
You can set the inverter output frequency with this function (F001) only
when you have specified "02" for the frequency source setting (A001). For
other methods of frequency setting, see Section 4.2.4, "frequency source
setting (A001)."
(If the setting of function "A001" is other than "02", function "F001" operates as the frequency command monitoring
function.)
The frequency set with function "F001" is automatically set as the Multispeed frequency setting (A020). To set the
second and third multispeed s, use the multispeed frequency setting, 2nd motor, function (A220) and multispeed
frequency setting, 3rd motor, function (A320), or use function "F001" for the setting after turning on the SET and SET3
signals. For the setting using the SET and SET3 signals, assign the SET function (08) and SET3 function (17) to intelligent
input terminals.
If the set output frequency is used as the target data for the PID function, PID feedback data will be displayed in
percent (%). ("100%" indicates the maximum frequency.)

As the operation commands via control circuit terminals, turn the FW
signal (for forward operation) or RV signal (for reverse operation) on and
off to start and stop the motor, respectively.
(Note that the factory setting assigns the FW signal to intelligent input terminal [8].)
To switch each intelligent input terminal between a and b contacts, specify each terminal with function "C011" to
"C019", and then perform input a/b (NO/NC) selection for each terminal.
When using the digital operation for the inverter operation, specify the desired motor operation direction with
function "F004", and use the RUN and STOP/RESET keys to start and stop the motor, respectively.
If the start commands for both forward and reverse operations are input at the same time, the inverter will assume
the input of a stop command.

4.2.8 Acceleration/deceleration time setting
- Specify a longer time for slower acceleration or deceleration;
specify a shorter time for quicker acceleration or deceleration.
- The time set with this function is the time to accelerate (or
decelerate) the motor from 0 Hz to the maximum frequency (or vice
versa).
- If you assign the acceleration/deceleration cancellation (LAC)
function to an intelligent input terminal and turns on the terminal,
the set acceleration/deceleration time will be ignored, and the
output frequency will immediately follow the frequency-setting command.
- To switch the acceleration and deceleration time among the 1st, 2nd, and 3rd settings, assign function "08" (SET) and
"17" (SET3) to intelligent input terminals (see Section 4.2.38). Use the SET and SET3 signals for switching.

4.2.9 Base frequency setting
(1) Base frequency and motor voltage
- With the base frequency setting and AVR voltage select functions,
adjust the inverter outputs (frequency and voltage) 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" (SET3) to
intelligent input terminals (see Section 4.2.38). Use the SET and SET3 signals for switching.

specified as the frequency to be added (A145) to or from the frequency
value of a selected frequency command.
To use this function, assign function "50" (ADD) to an intelligent input terminal.

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).

4.2.17 V/F characteristic curve selection

(1) Constant torque characteristic (VC)
With this control system set, the output voltage is in proportion to the output frequency within the range from 0 Hz to
the base frequency. Within the output frequency range over the base frequency up to the maximum frequency, the
output voltage is constant, regardless of the change in the output frequency.
(2) Reduced-torque characteristic (1.7th power of VP)
This control system is suited when the inverter is used with equipment (e.g., fan or pump) that does not require a large
torque at a low speed.
Since this control system reduces the output voltage at low frequencies, you can use it to increase the efficiency of
equipment operation and reduce the noise and vibrations generated from the equipment.
The V/f characteristic curve for this control system is shown below.
Period : While the output frequency increases from 0 Hz to the 10% of the base frequency, the output voltage
follows the constant torque characteristic.
(Example) If the base frequency is 60 Hz, the constant torque characteristic is maintained within the
output frequency range of 0 to 60 Hz.
Period : While the output frequency increases from the 10% of base frequency to the base
frequency, the output voltage follows the reduced-torque characteristic. In other words, the output
voltage increases according to the 1.7th power of the output frequency.
Period : While the output frequency increases from the base frequency to the maximum frequency, the output
voltage is constant.

(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.

(2) External DC braking
Assign function "07" (DB) to terminal function (C001 to C008).
Turn the DB terminal on and off to control the direct braking, regardless of the setting of DC braking enable (A051).
Adjust the braking force by adjusting the DC braking force setting (A054).
When you set the DC braking wait time (A053), the inverter output will be shut off for the set period of delay, and the
motor will run freely during the period. DC braking will be restarted after the delay.
When setting the DC braking time with function "A055" or for the DC braking operation via the DB terminal, determine
the length of time in consideration of the heat generation on the motor.
Select the braking mode by the DC braking/edge or level detection for [DB] input (A056), and then make any other
necessary settings suitable for your system.

(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 Example 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
Example 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 Example 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 o utput.
(Example 7-a) (Example 7-b)
How the inverter returns to the normal output varies depending on the setting of the DC braking/edge or level
detection for [DB] input (A054).

4.2.20 Frequency upper limit setting
The frequency upper limit setting function allows you to place upper and
lower limits on the inverter output frequency.
This function restricts the input of frequency commands that specify any
frequencies outside the upper and lower limits.
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 and lower
limit.
If 0 Hz is set for the frequency upper and lower limits, they will not operate.
The frequency limit setting function is disabled when the 3rd control system is selected.

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 jump.
Note that, while the inverter is accelerating or decelerating the motor,
the inverter output frequency changes continuously according to the set
acceleration/deceleration time.
You can set up to three frequencies to jump.

The acceleration stop frequency setting function allows you to make the
inverter wait, upon starting the motor, until the slipping of the motor
becomes less when the load on the motor causes a large moment of
inertia.
Use this function if the inverter has tripped because of overcurrent when starting the motor.
This function can operate with every acceleration pattern, regardless of the setting of the acceleration curve selection
(A097).

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), PID
rariation range (A078).

(2) PID operation
1) P operation
The proportional (P) operation stands for the operation in which the change in operation quantity is in proportion to
the change in target value.
2) I operation
The integral (I) operation stands for the operation in which the operation quantity increases linearly over time.
3) D operation
The derivative (D) operation stands for the operation in which the operation quantity changes in proportion to the
rate of change in the target value.
The PI operation is a combination of the P operation 1) and I operation 2). The PD operation is a combination of the
P operation 1) and D operation 3). The PDI operation is a combination of the P operation 1), I operation 2), and D
operation 3).
(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 (A005) 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") is specified for "A001".

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.
(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.
