Electric Shock Prevention
WARNING
While the inverter power is ON, do not remove the front cover or
the wiring cover. Do not run the inverter with the front cover or
the wiring cover removed. Otherwise you may access the
exposed high voltage terminals or the charging part of the
circuitry and get an electric shock.
Even if power is OFF, do not remove the front cover except for
wiring or periodic inspection. You may accidentally touch the
charged inverter circuits and get an electric shock.
Before wiring or inspection, power lamp must be switched OFF.
Any person who is involved in wiring or inspection shall wait for
at least 10 minutes after the power supply has been switched
OFF and check that there are no residual voltage using a tester
or the like. The capacitor is charged with high voltage for some
time after power OFF, and it is dangerous.
This inverter must be earthed (grounded). Earthing (grounding)
must conform to the requirements of national and local safety
regulations and electrical code (NEC section 250, IEC 536 class
1 and other applicable standards).
Any person who is involved in wiring or inspection of this
equipment shall be fully competent to do the work.
The inverter must be installed before wiring. Otherwise you may
get an electric shock or be injured.
Setting dial and key operations must be performed with dry
hands to prevent an electric shock. Otherwise you may get an
electric shock.
Do not subject the cables to scratches, excessive stress, heavy
loads or pinching. Otherwise you may get an electric shock.
Do not change the cooling fan while power is ON. It is dangerous
to change the cooling fan while power is ON.
Do not touch the printed circuit board or handle the cables with
wet hands. Otherwise you may get an electric shock.
A PM motor is a synchronous motor with high-performance
magnets embedded in the rotor. Motor terminals holds highvoltage while the motor is running even after the inverter power
is turned OFF. Before wiring or inspection, the motor must be
confirmed to be stopped. In an application, such as fan and
blower, where the motor is driven by the load, a low-voltage
manual motor starter must be connected at the inverter's output
side, and wiring and inspection must be performed while the
motor starter is open. Otherwise you may get an electric shock.
Fire Prevention
CAUTION
Inverter must be installed on a nonflammable wall without holes
(so that nobody touches the inverter heatsink on the rear side,
etc.). Mounting it to or near flammable material may cause a fire.
If the inverter has become faulty, the inverter power must be
switched OFF. A continuous flow of large current may cause a
fire.
Be sure to perform daily and periodic inspections as specified in
the Instruction Manual. If a product is used without any
inspection, a burst, breakage, or a fire may occur.
Injury Prevention
CAUTION
The voltage applied to each terminal must be the ones specified
in the Instruction Manual. Otherwise burst, damage, etc. may
occur.
The cables must be connected to the correct terminals.
Otherwise burst, damage, etc. may occur.
The polarity (+ and -) must be correct. Otherwise burst, damage,
etc. may occur.
While power is ON or for some time after power-OFF, do not
touch the inverter as it will be extremely hot. Touching these
devices may cause a burn.
Additional Instructions
The following instructions must be also followed. If the product
is handled incorrectly, it may cause unexpected fault, an injury,
or an electric shock.
CAUTION
Transportation and Mounting
Any person who is opening a package using a sharp object,
such as a knife and cutter, must wear gloves to prevent injuries
caused by the edge of the sharp object.
The product must be transported in correct method that
corresponds to the weight. Failure to do so may lead to injuries.
Do not stand or rest heavy objects on the product.
Do not stack the boxes containing inverters higher than the
number recommended.
When carrying the inverter, do not hold it by the front cover; it
may fall off or fail.
During installation, caution must be taken not to drop the inverter
as doing so may cause injuries.
The product must be installed on the surface that withstands the
weight of the inverter.
Do not install the product on a hot surface.
The mounting orientation of the inverter must be correct.
The inverter must be installed on a strong surface securely with
screws so that it will not drop.
Do not install or operate the inverter if it is damaged or has parts
missing.
Foreign conductive objects must be prevented from entering the
inverter. That includes screws and metal fragments or other
flammable substance such as oil.
As the inverter is a precision instrument, do not drop or subject it
to impact.
The surrounding air temperature for LD models must be
between -10 and +50°C (non-freezing). The surrounding air
temperature for SLD (initial setting) models must be between -10
and +40°C (non-freezing). Otherwise the inverter may be
damaged.
The ambient humidity must be 95%RH or less (non-
condensing). Otherwise the inverter may be damaged. (Refer to
page 17 for details.)
Safety Instructions

CAUTION
Transportation and Mounting
The storage temperature (applicable for a short time, e.g. during
transit) must be between -20 and +65°C. Otherwise the inverter
may be damaged.
The inverter must be used indoors (without corrosive gas,
flammable gas, oil mist, dust and dirt etc.) Otherwise the inverter
may be damaged.
The inverter must be used at an altitude of 2500 m or less above
sea level, with 2.9 m/s
(directions of X, Y, Z axes). Otherwise the inverter may be
damaged. (Refer to page 17 for details.)
If halogen-based materials (fluorine, chlorine, bromine, iodine,
etc.) infiltrate into a Mitsubishi product, the product will be
damaged. Halogen-based materials are often included in
fumigant, which is used to sterilize or disinfest wooden
packages. When packaging, prevent residual fumigant
components from being infiltrated into Mitsubishi products, or
use an alternative sterilization or disinfection method (heat
disinfection, etc.) for packaging. Sterilization of disinfection of
wooden package should also be performed before packaging
the product.
Wiring
Do not install a power factor correction capacitor or surge
suppressor/capacitor type filter on the inverter output side.
These devices on the inverter output side may be overheated or
burn out.
The output side terminals (terminals U, V, and W) must be
connected correctly. Otherwise the motor will rotate inversely.
PM motor terminals (U, V, W) hold high-voltage while the PM
motor is running even after the power is turned OFF. Before
wiring, the PM motor must be confirmed to be stopped.
Otherwise you may get an electric shock.
Never connect a PM motor to the commercial power supply.
Applying the commercial power supply to input terminals (U,V,
W) of a PM motor will burn the PM motor. The PM motor must
be connected with the output terminals (U, V, W) of the inverter.
Trial run
Before starting operation, each parameter must be confirmed
and adjusted. A failure to do so may cause some machines to
make unexpected motions.
2
or less vibration at 10 to 55 Hz
WARNING
Usage
Everyone must stay away from the equipment when the retry
function is set as it will restart suddenly after a trip.
Since pressing the STOP/RESET key may not stop output
depending on the function setting status, separate circuit and
switch that make an emergency stop (power OFF, mechanical
brake operation for emergency stop, etc.) must be provided.
OFF status of the start signal must be confirmed before resetting
the inverter fault. Resetting inverter fault with the start signal ON
restarts the motor suddenly.
Do not use a PM motor for an application where the PM motor is
driven by its load and runs at a speed higher than the maximum
motor speed.
Use this inverter only with three-phase induction motors or with a
PM motor. Connection of any other electrical equipment to the
inverter output may damage the equipment.
Do not modify the equipment.
Do not perform parts removal which is not instructed in this
manual. Doing so may lead to fault or damage of the product.
CAUTION
Usage
The electronic thermal relay function does not guarantee
protection of the motor from overheating. It is recommended to
install both an external thermal and PTC thermistor for overheat
protection.
Do not use a magnetic contactor on the inverter input for
frequent starting/stopping of the inverter. Otherwise the life of the
inverter decreases.
The effect of electromagnetic interference must be reduced by
using a noise filter or by other means. Otherwise nearby
electronic equipment may be affected.
Appropriate measures must be taken to suppress harmonics.
Otherwise power supply harmonics from the inverter may heat/
damage the power factor correction capacitor and generator.
When driving a 600V class motor by the inverter, the motor must
be an insulation-enhanced motor or measures must be taken to
suppress surge voltage. Surge voltage attributable to the wiring
constants may occur at the motor terminals, deteriorating the
insulation of the motor.
When parameter clear or all parameter clear is performed, the
required parameters must be set again before starting
operations because all parameters return to their initial values.
The inverter can be easily set for high-speed operation. Before
changing its setting, the performances of the motor and machine
must be fully examined.
Stop status cannot be hold by the inverter's brake function. In
addition to the inverter’s brake function, a holding device must
be installed to ensure safety.
Before running an inverter which had been stored for a long
period, inspection and test operation must be performed.
Static electricity in your body must be discharged beforeyou
touch the product.
Only one PM motor can be connected to an inverter.
A PM motor must be used under PM motor control. Do not use a
synchronous motor, induction motor, or synchronous induction
motor.
Do not connect a PM motor in the induction motor control
settings (initial settings). Do not use an induction motor in the
PM motor control settings. It will cause a failure.
In the system with a PM motor, the inverter power must be
turned ON before closing the contacts of the contactor at the
output side.
In order to protect the inverter and the system against
unauthorized access by external systems via network, take
security measures including firewall settings.
Depending on the network environment, the inverter may not
operate as intended due to delays or disconnection in
communication. Carefully consider the conditions and safety for
the inverter on site.
Emergency stop
A safety backup such as an emergency brake must be provided
to prevent hazardous conditions to the machine and equipment
in case of inverter failure.
When the breaker on the inverter input side trips, the wiring must
be checked for fault (short circuit), and internalparts of the
inverter for a damage, etc. The cause of the trip must be
identified and removed before turning ON the power of the
breaker.
When a protective function activates, take an appropriate
corrective action, then reset the inverter, and resume the
operation.
Maintenance, inspection and parts replacement
Do not carry out a megger (insulation resistance) test on the
control circuit of the inverter. It will cause a failure.
Disposal
The inverter must be treated as industrial waste.

The permissible surrounding air temperature of the inverter is between -10°C and +40°C (-10°C and +50°C at the LD ratings).
Always operate the inverter within this temperature range. Operation outside this range will considerably shorten the service
lives of the semiconductors, parts, capacitors and others. Take the following measures to keep the surrounding air
temperature of the inverter within the specified range.
(a) Measures against high temperature
• Use a forced ventilation system or similar cooling system. (Refer to page 19.)
• Install the enclosure in an air-conditioned electric chamber.
• Block direct sunlight.
• Provide a shield or similar plate to avoid direct exposure to the radiated heat and wind of a heat source.
• Ventilate the area around the enclosure well.
(b) Measures against low temperature
• Provide a space heater in the enclosure.
• Do not power OFF the inverter. (Keep the start signal of the inverter OFF.)
(c) Sudden temperature changes
• Select an installation place where temperature does not change suddenly.
• Avoid installing the inverter near the air outlet of an air conditioner.
• If temperature changes are caused by opening/closing of a door, install the inverter away from the door.

INSTALLATION AND WIRING

Installation of the inverter and enclosure design
Humidity
Operate the inverter within the ambient air humidity of usually 45 to 95%. Too high humidity will pose problems of reduced
insulation and metal corrosion. On the other hand, too low humidity may cause a spatial electrical breakdown. The insulation
distance defined in JEM1103 "Control Equipment Insulator" is humidity of 45 to 85%.
(a) Measures against high humidity
• Make the enclosure enclosed, and provide it with a hygroscopic agent.
• Provide dry air into the enclosure from outside.
• Provide a space heater in the enclosure.
(b) Measures against low humidity
Air with proper humidity can be blown into the enclosure from outside. Also when installing or inspecting the unit, discharge
your body (static electricity) beforehand, and keep your body away from the parts and patterns.
(c) Measures against condensation
Condensation may occur if frequent operation stops change the in-enclosure temperature suddenly or if the outside air
temperature changes suddenly.
Condensation causes such faults as reduced insulation and corrosion.
• Take the measures against high humidity in (a).
• Do not power OFF the inverter. (Keep the start signal of the inverter OFF.)
Dust, dirt, oil mist
Dust and dirt will cause such faults as poor contacts, reduced insulation and cooling effect due to the moisture-absorbed
accumulated dust and dirt, and in-enclosure temperature rise due to a clogged filter. In an atmosphere where conductive
powder floats, dust and dirt will cause such faults as malfunction, deteriorated insulation and short circuit in a short time.
Since oil mist will cause similar conditions, it is necessary to take adequate measures.
Countermeasure
• Place the inverter in a totally enclosed enclosure.
Take measures if the in-enclosure temperature rises. (Refer to page 19.)
• Purge air.
Pump clean air from outside to make the in-enclosure air pressure higher than the outside air pressure.
Corrosive gas, salt damage
If the inverter is exposed to corrosive gas or to salt near a beach, the printed board patterns and parts will corrode or the
relays and switches will result in poor contact.
In such places, take the measures given above.
Explosive, flammable gases
As the inverter is non-explosion proof, it must be contained in an explosion-proof enclosure. In places where explosion may
be caused by explosive gas, dust or dirt, an enclosure cannot be used unless it structurally complies with the guidelines and
has passed the specified tests. This makes the enclosure itself expensive (including the test charges). The best way is to
avoid installation in such places and install the inverter in a non-hazardous place.
High altitude
Use the inverter at an altitude of within 1000 m. For use at an altitude above 1,000 m (up to 2,500 m), derate the rated current
3% per 500 m.
If it is used at a higher place, it is likely that thin air will reduce the cooling effect and low air pressure will deteriorate dielectric
strength.

Vibration, impact
The vibration resistance of the inverter is up to 2.9 m/s2 at 10 to 55 Hz frequency and 1 mm amplitude for the directions of X,

even if those vibration and impacts are within the specified values.
Especially when impacts are applied repeatedly, caution must be taken because such impacts may break the installation feet.
Countermeasure
• Provide the enclosure with rubber vibration isolators.
• Strengthen the structure to prevent the enclosure from resonance.
• Install the enclosure away from the sources of the vibration.
2.3.2Cooling system types for inverter enclosure
From the enclosure that contains the inverter, the heat of the inverter and other equipment (transformers, lamps, resistors,
etc.) and the incoming heat such as direct sunlight must be dissipated to keep the in-enclosure temperature lower than the
permissible temperatures of the in-enclosure equipment including the inverter.
The cooling systems are classified as follows in terms of the cooling calculation method.
(a) Cooling by natural heat dissipation from the enclosure surface (totally enclosed type)
(b) Cooling by heatsink (aluminum fin, etc.)
(c) Cooling by ventilation (forced ventilation type, pipe ventilation type)
(d) Cooling by heat exchanger or cooler (heat pipe, cooler, etc.)

This system is for relatively small capacities.
Being a totally enclosed type, this system is the most
appropriate for hostile environment having dust, dirt, oil mist,
etc. The enclosure size increases depending on the inverter
capacity.
This system has restrictions on the heatsink mounting position
and area. This system is for relatively small capacities.
This system is for general indoor installation. This is

Inverter placement
• Install the inverter on a strong surface securely with screws.
• Leave enough clearances and take cooling measures.
• Avoid places where the inverter is subjected to direct sunlight, high temperature and high humidity.
• Install the inverter on a nonflammable wall surface.
• When encasing multiple inverters in an enclosure, install them in parallel as a cooling measure.
• For heat dissipation and maintenance, keep clearance between the inverter and the other devices or enclosure surface.
The clearance below the inverter is required as a wiring space, and the clearance above the inverter is required as a heat
dissipation space.
Installation orientation of the inverter
Install the inverter on a wall as specified. Do not mount it horizontally or in any other way.
Above the inverter
Heat is blown up from inside the inverter by the small fan built in the unit. Any equipment placed above the inverter should be
heat resistant.

Terminals R1/L11 and S1/L21 are connected to terminals P/+ and N/- with a jumper respectively. When using separate power supply for the
control circuit, remove the jumpers from R1/L11 and S1/L21.
The function of these terminals can be changed with the input terminal assignment (Pr.178 to Pr.189).
Terminal JOG is also used as the pulse train input terminal. Use Pr.291 to choose JOG or pulse.
The X10 signal (NC contact input specification) is assigned to the terminal MRS in the initial setting. Set Pr.599 = "0" to change the input
specification of the X10 signal to NO contact.
No function is assigned in the initial setting. Use Pr.186 for function assignment.
Terminal input specifications can be changed by analog input specification switchover (Pr.73, Pr.267). To input a voltage (0 to 5 V/0 to 10 V), set
the voltage/current input switch OFF. To input a current (4 to 20 mA), set the voltage/current input switch ON. Terminals 10 and 2 are also used
as a PTC input terminal. (Pr.561)
It is recommended to use 2 W 1 k when the frequency setting signal is changed frequently.
The function of these terminals can be changed with the output terminal assignment (Pr.195, Pr.196).
The function of these terminals can be changed with the output terminal assignment (Pr.190 to Pr.194).
No function is assigned in the initial setting. Use Pr.192 for function assignment.
The option connector 2 cannot be used because the Ethernet board is installed in the initial status. The Ethernet board must be removed to
install a plug-in option to the option connector 2. (However, Ethernet communication is disabled in that case.)
NOTE
• To prevent a malfunction due to noise, keep the signal cables 10 cm or more away from the power cables. Also, separate the
main circuit cables at the input side from the main circuit cables at the output side.
• After wiring, wire offcuts must not be left in the inverter.
Wire offcuts can cause an alarm, failure or malfunction. Always keep the inverter clean.
When drilling mounting holes in an enclosure etc., take caution not to allow chips and other foreign matter to enter the
inverter.
• Set the voltage/current input switch correctly. Incorrect setting may cause a fault, failure or malfunction.
• Terminals S1, S2, SIC, So (SO), and SOC are for manufacturer setting. Do not remove the shorting wires across terminals S1
and PC, terminals S2 and PC, and terminals SIC and SD. When the shorting wires are removed, the inverter does not
operate.
Connection between the converter unit and the inverter
Perform wiring so that the commands sent from the converter unit are transmitted to the inverter without fail. Incorrect
connection may damage the converter unit and the inverter.
For the wiring length, refer to the table below.
Total wiring length
For the cable gauge of the cable across the main circuit terminals P/+ and N/- (P and P, N and N), refer to page 28.
Do not install an MCCB across terminals P/+ and N/- (across terminals P and P/+ or across N and N/-). Connecting the opposite polarity of
terminals N/- and P/+ will damage the inverter.
For the terminal used for the X10 signal input, set "10" in any of Pr.178 to Pr.189 (Input terminal function selection) to assign the function.
(The X10 signal is assigned to terminal MRS in the initial setting.)
For the X10 signal, NC contact input specification is selected in the initial setting. Set Pr.599 = "0" to change the input specification to NO
contact.
For the terminal used for the X11 signal input, set "11" in any of Pr.178 to Pr.189 (Input terminal function selection) to assign the function. For
RS-485 or any other communication where the start command is only transmitted once, use the X11 signal to save the operation mode at the
time of an instantaneous power failure.
Always connect terminal RDA of the converter unit and terminal MRS (X10) of the inverter, and terminal SE of the converter unit and terminal SD
(sink logic) of the inverter. Not connecting these terminals may damage the converter unit.

The following table indicates a selection example for the wiring length of 20 m (575 V input power supply).
• Tighten the terminal screw to the specified torque.
A screw that has been tightened too loosely can cause a short circuit or malfunction.
A screw that has been tightened too tightly can cause a short circuit or malfunction due to the unit breakage.
• Use crimp terminals with insulation sleeves to wire the power supply and motor.

NOTE
• Especially for long-distance wiring, the inverter may be affected by a charging current caused by the stray capacitances of the
wiring, leading to a malfunction of the overcurrent protective function or fast response current limit function or a malfunction or
fault of the equipment connected on the inverter output side. If the fast-response current limit function malfunctions, disable

(III) Common earthing (grounding) cable.......Not allowed
2.5.5Earthing (grounding) precautions
• Always earth (ground) the motor, the inverter, and the converter unit.
Purpose of earthing (grounding)
Generally, an electrical apparatus has an earth (ground) terminal, which must be connected to the ground before use.
An electrical circuit is usually insulated by an insulating material and encased. However, it is impossible to manufacture an
insulating material that can shut off a leakage current completely, and actually, a slight current flows into the case. The
purpose of earthing (grounding) the case of an electrical apparatus is to prevent operators from getting an electric shock from
this leakage current when touching it.
To avoid the influence of external noises, this earthing (grounding) is important to audio equipment, sensors, computers and
other apparatuses that handle low-level signals or operate very fast.
Earthing (grounding) methods and earthing (grounding) work
As described previously, earthing (grounding) is roughly classified into an electrical shock prevention type and a noise-
influenced malfunction prevention type. Therefore, these two types should be clearly distinguished, and the following work
must be done to prevent the leakage current having the inverter's high frequency components from entering the malfunction
prevention type earthing (grounding):
• Whenever possible, use the independent earthing (grounding) for the inverter.
If independent earthing (grounding) (I) is not available, use (II) common earthing (grounding) in the figure below where the
inverter is connected with the other equipment at an earthing (grounding) point. Do not use the other equipment's earthing
(grounding) cable to earth (ground) the inverter as shown in (III).
A leakage current containing many high frequency components flows into the earthing (grounding) cables of the inverter
and peripheral devices. Because of this, the inverter must be earthed (grounded) separately from EMI-sensitive devices.
In a high building, it may be effective to use the EMI prevention type earthing (grounding) connecting to an iron structure
frame, and electric shock prevention type earthing (grounding) with the independent earthing (grounding) together.
• Earthing (Grounding) must conform to the requirements of national and local safety regulations and electrical codes.
(NEC section 250, IEC 536 class 1 and other applicable standards).
• use the thickest possible earthing (grounding) cable. The earthing (grounding) cable should be the size indicated in the
table on page 28.
• The earthing (grounding) point should be as close as possible to the inverter, and the earth (ground) wire length should
be as short as possible.
• Run the earthing (grounding) cable as far away as possible from the I/O wiring of equipment sensitive to noises and run
them in parallel in the minimum distance.

Inputting 0 to 5 VDC (or 0 to 10 V, 0 to 20 mA) provides the maximum
output frequency at 5 V (10 V, 20 mA) and makes input and output
proportional. Use Pr.73 to switch among input 0 to 5 VDC (initial

For the control circuit wiring, strip off the sheath of a cable, and use it with a blade terminal. For a single wire, strip off the
sheath of the wire and apply directly.
Insert the blade terminal or the single wire into a socket of the terminal.
(1) Strip off the sheath for the below length. If the length of the sheath peeled is too long, a short circuit may occur with
neighboring wires. If the length is too short, wires might come off.
Wire the stripped cable after twisting it to prevent it from becoming loose. In addition, do not solder it.

(2) Crimp the blade terminal.
Insert wires to a blade terminal, and check that the wires come out for about 0 to 0.5 mm from a sleeve.
Check the condition of the blade terminal after crimping. Do not use a blade terminal of which the crimping is inappropriate,
or the face is damaged.

2.6.5Wiring precautions
• It is recommended to use a cable of 0.75 mm2 for the connection to the control circuit terminals.
• The wiring length should be 30 m at the maximum.
• Use two or more parallel micro-signal contacts or twin contacts to prevent
contact faults when using contact inputs since the control circuit input signals
are micro-currents.
• To suppress EMI, use shielded or twisted cables for the control circuit
terminals and run them away from the main and power circuits (including the
200V relay sequence circuit). For the cables connected to the control circuit terminals, connect their shields to the common
terminal of the connected control circuit terminal. When connecting an external power supply to the terminal PC, however,
connect the shield of the power supply cable to the negative side of the external power supply. Do not directly earth
(ground) the shield to the enclosure, etc.
• Always apply a voltage to the fault output terminals (A1, B1, C1, A2, B2, C2) via a relay coil, lamp, etc.
• Separate the wiring of the control circuit away from the wiring of the main circuit.
Make cuts in rubber bush of the inverter side and lead the wires through.

When a fault occurs, opening of the electromagnetic contactor (MC) on the inverter power supply side results in power loss in
the control circuit, disabling the fault output signal retention. Terminals R1/L11 and S1/L21 are provided to hold a fault signal.
In this case, connect the power supply terminals R1/L11 and S1/L21 of the control circuit to the input side of the MC.
The terminals R1/L11 and S1/L21 are connected to the terminals P/+ and N/- with a jumper respectively. Do not connect the
power cable to incorrect terminals. Doing so may damage the inverter.

Starting and stopping the 24 V external power supply operation
• Supplying 24 V external power while the main circuit power is OFF starts the 24 V external power supply operation.
Likewise, turning OFF the main circuit power while supplying 24 V external power starts the 24 V external power supply
operation.
• Turning ON the main circuit power stops the 24 V external power supply operation and enables the normal operation.
NOTE
• When the 24 V external power is supplied while the main circuit power supply is OFF, the inverter operation is disabled.
• In the initial setting, when the main power supply is turned ON during the 24 V external power supply operation, a reset is
performed in the inverter, then the power supply changes to the main circuit power supply. (The reset can be disabled using
Pr.30.)
Confirming the 24 V external power supply input
• During the 24 V external power supply operation, the alarm lamp blinks.
• During the 24 V external power supply operation, the 24 V external power supply operation signal (EV) is output. To use the
EV signal, set "68 (positive logic) or 168 (negative logic)" in one of Pr.190 to Pr.196 (Output terminal function selection)
to assign function to an output terminal.

Operation while the 24 V external power is supplied
• Faults history and parameters can be read and parameters can be written (when the parameter write from the operation

• The safety stop function is disabled during the 24 V external power supply operation.
• During the 24 V external power supply operation, monitored items related to inputs to main circuit power supply, such as
output current and converter output voltage, are invalid.
• The alarms, which have occured when the main circuit power supply is ON, continue to be output after the power supply is
changed to the 24 V external power supply. Perform the inverter reset or turn OFF then ON the power to reset the faults.
• The output data is retained when "1 or 11" is set in Pr.495 Remote output selection.
• Inrush current equal to or higher than the 24 V external power supply specification may flow at power-ON. Confirm that the
power supply and other devices are not affected by the inrush current and the voltage drop caused by it. Depending on the
power supply, the inrush current protection may be activated to disable the power supply. Select the power supply and
capacity carefully.
• When the wiring length between the external power supply and the inverter is long, the voltage often drops. Select the
appropriate wiring size and length to keep the voltage in the rated input voltage range.
• In a serial connection of several inverters, the current increases when it flows through the inverter wiring near the power
supply. The increase of the current causes voltage to drop further. Use the inverter after confirming that the input voltage of
each converter unit is within the rated input voltage range. Depending on the power supply, the inrush current protection may
be activated to disable the power supply. Select the power supply and capacity carefully.
• "E.SAF" or "E.P24" may appear when the start-up time of the 24 V power supply is too long (less than 1.5 V/s) in the 24 V

3.1Electro-magnetic interference (EMI) and
leakage currents
3.1.1Leakage currents and countermeasures
Capacitances exist between the inverter I/O cables, other cables and earth and in the motor, through which a leakage current
flows. Since its value depends on the static capacitances, carrier frequency, etc., low acoustic noise operation at the
increased carrier frequency of the inverter will increase the leakage current. Therefore, take the following countermeasures.
Select the earth leakage current breaker according to its rated sensitivity current, independently of the carrier frequency
setting.
To-earth (ground) leakage currents
Leakage currents may flow not only into the inverter's own line but also into the other lines through the earthing (grounding)
cable, etc. These leakage currents may operate earth leakage circuit breakers and earth leakage relays unnecessarily.
Countermeasures
• If the carrier frequency setting is high, decrease the Pr.72 PWM frequency selection setting.
Note that motor noise increases. Selecting Pr.240 Soft-PWM operation selection makes the sound inoffensive.
• By using earth leakage circuit breakers designed for harmonic and surge suppression in the inverter's own line and other
line, operation can be performed with the carrier frequency kept high (with low noise).
To-earth (ground) leakage currents
• Take caution as long wiring will increase the leakage current. Decreasing the carrier frequency of the inverter reduces the
leakage current.
• Increasing the motor capacity increases the leakage current.
Line-to-line leakage currents
Harmonics of leakage currents flowing in static capacitances between the inverter output cables may operate the external
thermal relay unnecessarily.
Countermeasures
• Use Pr.9 Electronic thermal O/L relay.
• If the carrier frequency setting is high, decrease the Pr.72 PWM frequency selection setting.
Note that motor noise increases. Selecting Pr.240 Soft-PWM operation selection makes the sound inoffensive.
To ensure that the motor is protected against line-to-line leakage currents, it is recommended to use a temperature sensor
to directly detect motor temperature.
Installation and selection of the molded case circuit breaker
Install a molded case circuit breaker (MCCB) on the power receiving side to protect the wiring at the inverter input side.
Select an MCCB according to the inverter input side power factor, which depends on the power supply voltage, output
frequency and load. Especially for a completely electromagnetic MCCB, a slightly large capacity must be selected since its
operation characteristic varies with harmonic currents. (Check it in the data of the corresponding breaker.)

3.1.2Countermeasures against inverter-generated
EMI
Some electromagnetic noises enter the inverter or the converter unit to cause its malfunction, and others are radiated by the
inverter or the converter unit to cause the peripheral devices to malfunction. Though the inverter or the converter unit is
designed to have high immunity performance, it handles low-level signals, so it requires the following basic techniques. Also,
since the inverter chops outputs at high carrier frequency, that could generate electromagnetic noises. If these
electromagnetic noises cause peripheral devices to malfunction, EMI countermeasures should be taken to suppress noises.
These techniques differ slightly depending on EMI paths.
• Basic techniques
- Do not run the power cables (I/O cables) and signal cables of the inverter or the converter unit in parallel with each other
and do not bundle them.
- Use shielded twisted pair cables for the detector connecting and control signal cables and connect the sheathes of the
shielded cables to terminal SD.
- Ground (Earth) the inverter or the converter unit, motor, etc. at one point.
• Techniques to reduce electromagnetic noises that enter and cause a malfunction of the inverter or the converter unit (EMI
countermeasures)
When devices that generate many electromagnetic noises (which use magnetic contactors, electromagnetic brakes, many
relays, for example) are installed near the inverter or the converter unit and it may malfunction due to electromagnetic
noises, the following countermeasures must be taken:
- Provide surge suppressors for devices that generate many electromagnetic noises to suppress electromagnetic noises.
- Install data line filters (page 50) to signal cables.
- Ground (Earth) the shields of the detector connection and control signal cables with cable clamp metal.
• Techniques to reduce electromagnetic noises that are radiated by the inverter or converter unit to cause the peripheral
devices to malfunction (EMI countermeasures)
Noises generated from the inverter or the converter unit are largely classified into those radiated by the cables connected to
the inverter or the converter unit and its main circuits (I/O), those electromagnetically and electrostatically induced to the
signal cables of the peripheral devices close to the main circuit power supply, and those transmitted through the power
supply cables.

Countermeasure
When devices that handle low-level signals and are liable to malfunction due to electromagnetic noises, e.g.
instruments, receivers and sensors, are contained in the enclosure that contains the inverter or the converter unit,
or when their signal cables are run near the inverter, the devices may malfunction due to by air-propagated
electromagnetic noises. The following countermeasures must be taken:
• Install easily affected devices as far away as possible from the inverter or the converter unit.
• Run easily affected signal cables as far away as possible from the inverter or the converter unit, and its I/O
cables.
• Do not run the signal cables and power cables (inverter or converter unit I/O cables) in parallel with each other
and do not bundle them.
• Inserting a line noise filter into the output suppresses the radiated noise from the cables.
• Use shielded cables as signal cables and power cables and run them in individual metal conduits to produce
further effects.
When the signal cables are run in parallel with or bundled with the power cables, magnetic and static induction
noises may be propagated to the signal cables to cause malfunction of the devices and the following
countermeasures must be taken:
• Install easily affected devices as far away as possible from the inverter or the converter unit.
• Run easily affected signal cables as far away as possible from the inverter or the converter unit, and its I/O
cables.
• Do not run the signal cables and power cables (inverter or converter unit I/O cables) in parallel with each other
and do not bundle them.
• Use shielded cables as signal cables and power cables and run them in individual metal conduits to produce
further effects.
When the power supplies of the peripheral devices are connected to the power supply of the inverter or the
converter unit in the same line, its generated noises may flow back through the power supply cables to cause
malfunction of the devices and the following countermeasures must be taken:
• Install the line noise filter to the power cables (output cables) of the inverter.
When a closed loop circuit is formed by connecting the peripheral device wiring to the inverter or the converter unit,
leakage currents may flow through the earthing (grounding) cable of the inverter or the converter unit to cause the
device to malfunction. In that case, disconnecting the earthing (grounding) cable from the device may stop the
malfunction of the device.
Data line filter
Data line filter is effective as an EMI countermeasure. Provide a data line filter for the detector cable, etc.

3.2Power supply harmonics
3.2.1Power supply harmonics
The inverter may generate power supply harmonics from its converter circuit to affect the power generator, power factor
correction capacitor etc. Power supply harmonics are different from noise and leakage currents in source, frequency band and
transmission path. Take the following countermeasure suppression techniques.
• The differences between harmonics and noises
ItemHarmonicsNoise
Frequency
EnvironmentTo-electric channel, power impedance.To-space, distance, wiring path,
Generated amountNearly proportional to the load capacity.
Affected equipment immunity Specified by standards per equipment.Different depending on maker's equipment specifications.
CountermeasureProvide a reactor.Increase distance.
Normally 40th to 50th degrees or less (3 kHz
or less).
• Countermeasures
The harmonic current generated from the inverter
to the input side differs according to various
conditions such as the wiring impedance,
whether a reactor is used or not, and output
frequency and output current on the load side.
For the output frequency and output current, we
understand that this should be calculated in the
conditions under the rated load at the maximum
operating frequency.
The converter unit (FR-CC2-C) is equipped with the DC reactor.
High frequency (several 10 kHz to 1 GHz order).
Changes with the current variation ratio. (Gets larger as
switching speed increases.)
• The power factor improving capacitor and surge suppressor on the inverter output side may be overheated or damaged by
the harmonic components of the inverter output. Also, since an excessive current flows in the inverter to activate overcurrent
protection, do not provide a capacitor and surge suppressor on the inverter output side when the motor is driven by the
inverter. For power factor improvement, install a reactor on the inverter input side or in the DC circuit.
3.3Installation of a reactor
When the inverter is connected near a large-capacity power transformer (1000 kVA or more) or when a power factor
correction capacitor is to be switched over, an excessive peak current may flow in the power input circuit, damaging the
converter circuit. To prevent this, always install an AC reactor.

3.4Power-OFF and magnetic contactor (MC)
Converter unit input side magnetic contactor (MC)
On the converter unit input side, it is recommended to provide an MC for the following purposes:
(Refer to page 14 for selection.)
• To disconnect the inverter from the power supply at activation of a protective function or at malfunctioning of the driving
system (emergency stop, etc.).
• To prevent any accident due to an automatic restart at power restoration after an inverter stop made by a power failure.
• To separate the inverter from the power supply to ensure safe maintenance and inspection work.
If using an MC for emergency stop during operation, select an MC regarding the converter unit input side current as
JEM1038-AC-3 class rated current.
• Since repeated inrush currents at power ON will shorten the life of the converter circuit (switching life is about 1,000,000
times), frequent starts and stops of the magnetic contactor must be avoided. Turn ON/OFF the inverter start controlling
terminals (STF, STR) to run/stop the inverter.
• Inverter start/stop circuit example
As shown below, always use the start signal (ON or OFF of STF(STR) signal) to make a start or stop.
Install a stepdown transformer.
Connect the power supply terminals R1/L11, S1/L21 of the control circuit to the input side of the MC to hold an alarm signal when the inverter's
protective circuit is activated. At this time, remove jumpers across terminals R1/L11 and S1/L21. (Refer to page 40 for removal of the jumper.)
Handling of the magnetic contactor on the inverter's output side
Switch the magnetic contactor between the inverter and motor only when both the inverter and motor are at a stop. When the
magnetic contactor is turned ON while the inverter is operating, overcurrent protection of the inverter and such will activate.
When an MC is provided to switch to a commercial power supply, for example, it is recommended to use the electronic bypass
function Pr.135 to Pr.139. (The commercial power supply operation is not available with PM motors.)
Handling of the manual contactor on the inverter's output side
A PM motor is a synchronous motor with high-performance magnets embedded inside. High-voltage is generated at the motor
terminals while the motor is running even after the inverter power is turned OFF. In an application where the PM motor is
driven by the load even after the inverter is powered OFF, a low-voltage manual contactor must be connected at the inverter's
output side.
PRECAUTIONS FOR USE OF THE INVERTER
52
Countermeasures against deterioration of the 600 V class motor insulation
NOTE
• Before wiring or inspection for a PM motor, confirm that the PM motor is stopped. In an application, such as fan and blower,
where the motor is driven by the load, a low-voltage manual contactor must be connected at the inverter's output side, and
wiring and inspection must be performed while the contactor is open. Otherwise you may get an electric shock.
• Do not open or close the contactor while the inverter is running (outputting).
3.5Countermeasures against deterioration of
the 600 V class motor insulation
In the PWM type inverter, a surge voltage attributable to wiring constants is generated at the motor terminals.
Especially for a 600V class motor, the surge voltage may deteriorate the insulation.

When the 600V class motor is driven by the inverter, consider the following measures:
Measures

Select an inverter duty motor. Many motor manufacturers sell motors with insulation systems designed to withstand the
stress imposed by PWM inverters
• AC reactor
For added protection, install an AC reactor on the inverter output

Checklist before starting operation
3.6Checklist before starting operation
The FR-F860 series inverter and FR-CC2-C converter unit are highly reliable products, but incorrect peripheral circuit making
or operation/handling method may shorten the product life or damage the products.
Before starting operation, always recheck the following points.
CheckpointCountermeasure
Crimp terminals are insulated.
The wiring between the power
supply (R/L1, S/L2, T/L3) and the
motor (U, V, W) is correct.
No wire offcuts are left from the time
of wiring.
The main circuit cable gauge is
correctly selected.
The total wiring length is within the
specified length.
Countermeasures are taken against
EMI.
Countermeasures are taken against
electrical corrosion on the motor
bearing.
On the inverter's output side, there
is no power factor correction
capacitor, surge suppressor, or
radio noise filter installed.
When performing an inspection or
rewiring on the product that has
been energized, the operator has
waited long enough after shutting off
the power supply.
The inverter's output side has no
short circuit or ground fault
occurring.
The circuit is not configured to use
the converter unit's input-side
magnetic contactor to start/stop the
inverter frequently.
Use crimp terminals with insulation sleeves to wire the power supply and the
motor.
Application of power to the output terminals (U, V, W) of the inverter will
damage the inverter. Never perform such wiring.
Wire offcuts can cause an alarm, failure or malfunction. Always keep the
inverter and the converter unit clean.
When drilling mounting holes in an enclosure etc., take caution not to allow
chips and other foreign matter to enter the inverter and the converter unit.
Use an appropriate cable gauge to suppress the voltage drop to 2% or less.
If the wiring distance is long between the inverter and motor, the voltage drop
in the main circuit will cause the motor torque to decrease especially during the
output of a low frequency.
Keep the total wiring length is within the specified length.
In long distance wiring, charging currents due to stray capacitance in the wiring
may degrade the fast-response current limit operation or cause the equipment
on the inverter's output side to malfunction. Pay attention to the total wiring
length.
The input/output (main circuit) of the inverter and the converter unit includes
high frequency components, which may interfere with the communication
devices (such as AM radios) used near the inverter and the converter unit. In
such case, install a noise filter to minimize interference.
When a motor is driven by the inverter, axial voltage is generated on the motor
shaft, which may cause electrical corrosion of the bearing in rare cases
depending on the wiring, load, operating conditions of the motor or a specific
inverter setting (high carrier frequency).
Contact your sales representative to take appropriate countermeasures for the
motor.
The following shows examples of countermeasures for the inverter.
• Decrease the carrier frequency.
• Provide a common mode choke on the output side of the inverter.
Recommended common mode choke: FT-3KM F series FINEMET®
common mode choke cores manufactured by Hitachi Metals, Ltd.
FINEMET is a registered trademark of Hitachi Metals, Ltd.
Doing so will cause the inverter to trip or the capacitor and surge suppressor to
be damaged. If any of the above devices is connected, immediately remove it.
For a short time after the power-OFF, a high voltage remains in the smoothing
capacitor, and it is dangerous.
Before performing an inspection or rewiring, wait 10 minutes or longer after the
power supply turns OFF, then confirm that the voltage across the main circuit
terminals P/+ and N/- of the inverter is low enough using a tester, etc.
• A short circuit or earth (ground) fault on the inverter's output side may
damage the inverter module.
• Fully check the insulation resistance of the circuit prior to inverter operation
since repeated short circuits caused by peripheral circuit inadequacy or an
earth (ground) fault caused by wiring inadequacy or reduced motor insulation
resistance may damage the inverter module.
• Fully check the to-earth (ground) insulation and phase-to-phase insulation of
the inverter's output side before power-ON. Especially for an old motor or use
in hostile atmosphere, securely check the motor insulation resistance, etc.
Since repeated inrush currents at power ON will shorten the life of the inverter
and the converter unit, frequent starts and stops of the magnetic contactor
must be avoided. Turn ON/OFF the inverter's start signals (STF, STR) to run/
stop the inverter.

potentiometer from being connected incorrectly to short circuit the terminals
10E and 5.
• Make sure that terminal P/+ of the converter unit and terminal P/+ of the
inverter, and terminal N/- of the converter unit and terminal N- of the inverter
are correctly connected.
Connecting the opposite polarity of terminals N/- and P/+ will damage the
inverter.
Also, do not install an MCCB across terminals P/+ and N/- (across terminals
P and P/+ or across N and N/-).
• Always connect terminal RDA of the converter unit and terminal MRS (X10)
of the inverter, and terminal SE of the converter unit and terminal SD
(terminal PC for source logic) of the inverter.
Not connecting these terminals may damage the converter unit.
When using a switching circuit as shown below, chattering due to misconfigured sequence or arc generated at switching may allow undesirable

inverter's output side is properly
handled.
When using a PM motor, a lowvoltage manual contactor is installed
on the inverter's output side.
An EMI countermeasure is provided
for the frequency setting signals.
If switching to the commercial power supply operation while a failure such as
an output short circuit has occurred between the magnetic contactor MC2 and
the motor, the damage may further spread. If a failure has occurred between
the MC2 and the motor, a protection circuit such as using the OH signal input
must be provided.
If the machine must not be restarted when power is restored after a power
failure, provide an MC in the converter unit's input side and also make up a
sequence which will not switch ON the start signal. If the start signal (start
switch) remains ON after a power failure, the inverter will automatically restart
as soon as the power is restored.
On the converter unit's input side, connect an MC for the following purposes:
• To disconnect the inverter and the converter unit from the power supply at
activation of a protective function or at malfunctioning of the driving system
(emergency stop, etc.).
• To prevent any accident due to an automatic restart at power restoration after
an inverter stop made by a power failure.
• To separate the inverter and the converter unit from the power supply to
ensure safe maintenance and inspection work.
If using an MC for emergency stop during operation, select an MC regarding
the converter unit input side current as JEM1038-AC-3 class rated current.
Switch the magnetic contactor between the inverter and motor only when both
the inverter and motor are at a stop.
A PM motor is a synchronous motor with high-performance magnets
embedded inside. High-voltage is generated at the motor terminals while the
motor is running even after the inverter power is turned OFF. In an application,
such as fan and blower, where the motor is driven by the load, a low-voltage
manual contactor must be connected at the inverter's output side, and wiring
and inspection must be performed while the contactor is open. Otherwise you
may get an electric shock.
If electromagnetic noise generated from the inverter and the converter unit
causes frequency setting signal to fluctuate and the motor rotation speed to be
unstable when changing the motor speed with analog signals, the following
countermeasures are effective:
• Do not run the signal cables and power cables (inverter and converter unit I/O
cables) in parallel with each other and do not bundle them.
• Run signal cables as far away as possible from power cables (inverter and
converter I/O cables).
• Use shielded cables.
• Install a ferrite core on the signal cable.

Checklist before starting operation
CheckpointCountermeasure
A countermeasure is provided for an
overload operation.
The specifications and rating match
the system requirements.
When performing frequent starts/stops by the inverter, rise/fall in the
temperature of the transistor element of the inverter will repeat due to a
repeated flow of large current, shortening the life from thermal fatigue. Since
thermal fatigue is related to the amount of current, the life can be increased by
reducing current at locked condition, starting current, etc. Reducing current
may extend the service life but may also cause torque shortage, which leads to
a start failure. Adding a margin to the current can eliminate such a condition.
For an induction motor, use the inverter and the converter unit of a higher
capacity (up to two ranks). For a PM motor, use the inverter and the converter
unit, and PM motor of higher capacities.
Make sure that the specifications and rating match the system requirements.-

3.7Failsafe system which uses the inverter
When a fault is detected by the protective function, the protective function activates and outputs a fault signal. However, a
fault signal may not be output at an inverter's fault occurrence when the detection circuit or output circuit fails, etc. Although
Mitsubishi assures the best quality products, provide an interlock which uses inverter status output signals to prevent
accidents such as damage to the machine when the inverter fails for some reason. Also at the same time consider the system
configuration where a failsafe from outside the inverter, without using the inverter, is enabled even if the inverter fails.
Interlock method which uses the inverter status output signals
By combining the inverter output signals to provide an interlock as shown below, an inverter failure can be detected.

dInverter running statusLogic check of the start signal and output current.
(a) Checking by the output of the inverter fault signal
When the inverter's protective function activates and the
inverter trips, the Fault (ALM) signal is output. (The ALM
signal is assigned to terminal A1B1C1 in the initial
setting).
With this signal, check that the inverter operates
properly.
In addition, negative logic can be set. (ON when the
inverter is normal, OFF when the fault occurs.)

(b) Checking the inverter operating status by the inverter
operation ready completion signal
The Operation ready (RY) signal is output when the
inverter power is ON and the inverter becomes
operative.
Check if the RY signal is output after powering ON the
inverter.
(c) Checking the inverter operating status by the start signal
input to the inverter and inverter running signal
The Inverter running (RUN) signal is output when the
inverter is running. (The RUN signal is assigned to
terminal RUN in the initial setting.)
Check if the Y12 signal is being output while inputting a
start signal to the inverter. (The STF signal is a forward
rotation signal, and the STR signal is a reverse rotation
signal.) Even after the start signal is turned OFF, the
RUN signal is kept output until the inverter makes the
motor to decelerate and to stop. For the logic check,
configure a sequence considering the inverter's
deceleration time.

(d) Checking the motor operating status by the start signal input to the inverter and inverter output current detection signal
The Output current detection (Y12) signal is output when the inverter operates and current flows into the motor.
Check if the Y12 signal is being output while inputting a start signal to the inverter. (The STF signal is a forward rotation
signal, and the STR signal is a reverse rotation signal.) The Y12 signal is initially set to be output at 110% rated inverter
current. Adjust the level to around 20% using no load current of the motor as reference with Pr.150 Output current
detection level.
Like the Inverter running (RUN) signal, even after the start signal is turned OFF, the Y12 signal is kept output until the
inverter stops the output to a decelerating motor. For the logic check, configure a sequence considering the inverter's
deceleration time.
• When using various signals, assign the functions to Pr.190 and
Pr.196 (Output terminal function selection) referring to the
table on the left.
• Changing the terminal assignment using Pr.190 and Pr.196 (Output terminal function selection) may affect the other
functions. Set parameters after confirming the function of each terminal.
• For the details of the parameters and signals, refer to the FR-F860 Instruction Manual (Detailed).
Backup method outside the inverter
Even if the interlock is provided by the inverter status signal, enough failsafe is not ensured depending on the failure status of
the inverter itself. For example, if an inverter CPU fails in a system interlocked with the inverter's Fault, STF/STR, and RUN
signals, no fault signal will be output and the RUN signal will be kept ON because the inverter CPU is down.
Provide a speed detector to detect the motor speed and current detector to detect the motor current and consider the backup
system such as performing a check as below according to the level of importance of the system.
(a) Start signal and actual operation check
Check the motor running and motor current while the start signal is input to the inverter by comparing the start signal to
the inverter and detected speed of the speed detector or detected current of the current detector. Note that the current
is flowing through the motor while the motor coasts to stop, even after the inverter's start signal is turned OFF. For the
logic check, configure a sequence considering the inverter's deceleration time. In addition, it is recommended to check
the three-phase current when using the current detector.
(b) Command speed and actual operation check
Check for a gap between the actual speed and commanded speed by comparing the inverter's speed command and
the speed detected by the speed detector.

AlarmThe inverter output is not shut off. An Alarm (LF) signal can also be output with a parameter setting.
FaultA protective function is activated to shut off the inverter output and output a Fault (ALM) signal.
Opening the magnetic contactor (MC) provided on the input side of the inverter at a fault occurrence
shuts off the control power to the inverter, therefore, the fault output will not be retained.
While a protective function is activated, the inverter output is kept shutoff. Reset the inverter to restart
the operation.
A message regarding an operational fault and setting fault by the operation panel and parameter unit
is displayed. The inverter output is not shut off.
The inverter output is not shut off even when a warning is displayed. However, failure to take
appropriate measures will lead to a fault.
• For the details of fault displays and other malfunctions, refer to the FR-F860 Instruction Manual (Detailed).
• The past eight faults can be displayed on the operation panel. (Faults history) (For the operation, refer to the operation panel
or the parameter unit Instruction Manual.)
4.2Reset method for the protective functions
Reset the inverter by performing any of the following operations. Note that the accumulated heat value of the electronic
thermal relay function and the number of retries are cleared (erased) by resetting the inverter.
The inverter recovers about 1 s after the reset is released.
• On the operation panel, press the STOP/RESET key to reset the
inverter.
(This may only be performed when a fault occurs.)
• Switch power OFF once, then switch it ON again.
• Turn ON the Inverter reset (RES) signal for 0.1 s or more. (If the
RES signal is kept ON, "Err" appears (blinks) to indicate that the
inverter is in a reset status.)

Change the polarity of the tester alternately at the inverter terminals R/L1, S/L2, T/L3, U, V, W, P/+, and N/- and check the
electric continuity.
• Before measurement, check that the smoothing capacitor is discharged.
• At the time of electric discontinuity, the measured value is almost ∞. When there is an instantaneous electric continuity, due to
the smoothing capacitor, the tester may not indicate ∞. At the time of electric continuity, the measured value is several to
several tens of . If all measured values are almost the same, although these values are not constant depending on the
module type and tester type, the modules are without fault.

NOTE
5.1.5Cleaning
Always run the inverter in a clean status.
When cleaning the inverter, gently wipe dirty areas with a soft cloth immersed in neutral detergent or ethanol.
• Do not use solvent, such as acetone, benzene, toluene and alcohol, as these will cause the inverter surface paint to peel off.
• The display, etc. of the operation panel and parameter unit are vulnerable to detergent and alcohol. Therefore, avoid using
them for cleaning.
5.1.6Replacement of parts
The inverter consists of many electronic parts such as semiconductor devices.
The following parts may deteriorate with age because of their structures or physical characteristics, leading to reduced
performance or fault of the inverter. For preventive maintenance, the parts must be replaced periodically.
Use the life check function as a guidance of parts replacement.

Replacement procedure of the cooling fan
The replacement interval of the cooling fan used for cooling the parts generating heat such as the main circuit semiconductor
is greatly affected by the surrounding air temperature. When unusual noise and/or vibration are noticed during inspection, the
cooling fan must be replaced immediately.
Removal
1) Remove the fan cover fixing screws, and remove the fan cover.
2) Disconnect the fan connector and remove the fan block.
3) Remove the fan fixing screws, and remove the fan.
The number of cooling fans differs according to the inverter capacity.
Reinstallation
1) After confirming the orientation of the fan, reinstall the fan so that the "AIR FLOW " faces up.
2) For reconnection of the fan, refer to the above figure.
• Installing the fan in the opposite direction of air flow can cause the inverter life to be shorter.
• Prevent the cable from being caught when installing a fan.
• Switch the power OFF before replacing fans. Since the inverter circuits are charged with voltage even after power OFF,
replace fans only when the inverter cover is on the inverter to prevent an electric shock accident.

PRECAUTIONS FOR MAINTENANCE AND INSPECTION
Inspection item
NOTE
Smoothing capacitors
A large-capacity aluminum electrolytic capacitor is used for smoothing in the main circuit DC section, and an aluminum
electrolytic capacitor is used for stabilizing the control power in the control circuit. Their characteristics are deteriorated by the
adverse effects of ripple currents, etc. The replacement intervals greatly vary with the surrounding air temperature and
operating conditions. When the inverter is operated in air-conditioned, normal environment conditions, replace the capacitors
about every 10 years.
The appearance criteria for inspection are as follows:
• Case: Check the side and bottom faces for expansion.
• Sealing plate: Check for remarkable warp and extreme crack.
• heck for external crack, discoloration, liquid leakage, etc. Judge that the capacitor has reached its life when the measured
capacitance of the capacitor reduced below 80% of the rating.
• The inverter diagnoses the control circuit capacitor by itself and can judge its life. (Refer to the FR-F860 Instruction Manual
(Detailed))
Relays
• To prevent a contact fault, etc., relays must be replaced according to the cumulative number of switching times (switching
life).
• The control terminal block must be replaced in case of failure of either relay connected to the relay output terminals A1, B1,
and C1, or A2, B2, and C2. (After replacing the control terminal block, connect the jumper connector to the correct position
in accordance with the control logic of input signals. (Refer to page 35.))
Main circuit fuse
A fuse is used inside the inverter. The replacement intervals vary with the surrounding air temperature and operating
conditions. When the converter unit is operated in air-conditioned, normal environment conditions, replace the capacitors
about every 10 years.
5.1.7Inverter replacement
The inverter can be replaced with the control circuit wiring kept connected.
1) Loosen the two mounting screws at the both side of the control circuit terminal block. (These screws cannot be removed.)
Slide down the control circuit terminal block to remove it.
Loosen the screws
2) Be careful not to bend the pins of the inverter's control circuit connector, reinstall the control circuit terminal block and fix it
with the mounting screws.
NOTE
• Before starting inverter replacement, switch power OFF, wait for at least 10 minutes, and then check the voltage with a tester
and such to ensure safety.

5.2Measurement of main circuit voltages,
currents and powers
Since the voltages and currents on the inverter power supply and output sides include harmonics, measurement data
depends on the instruments used and circuits measured.
When instruments for commercial frequency are used for measurement, measure the following circuits with the instruments
given on the next page.
• When installing meters etc. on the inverter output side
When the wiring length between the inverter and the motor is large, the meters and CTs may generate heat due to line-to-line
leakage current. Therefore, choose the equipment which has enough allowance for the current rating.
To measure and display the output voltage and output current of the inverter, it is recommended to use the terminal AM and
CA output functions of the inverter.

PRECAUTIONS FOR MAINTENANCE AND INSPECTION

Measurement of main circuit voltages, currents and powers
5.2.1Measurement of powers
Use a digital power meter (for inverter) for the input side of the converter unit (FR-CC2-C) and the output side of the inverter.
Alternatively, measure using electrodynamic type single-phase wattmeters for the input side of the converter unit and output
side of the inverter in two-wattmeter or three-wattmeter method. As the current is liable to be imbalanced especially in the
input side, it is recommended to use the three-wattmeter method.
Examples of measured value differences produced by different measuring meters are shown below.
An error will be produced by difference between measuring instruments, e.g. power calculation type and two- or three-
wattmeter type three-phase wattmeter. When a CT is used in the current measuring side or when the meter contains a PT on
the voltage measurement side, an error will also be produced due to the frequency characteristics of the CT and PT.
[Measurement conditions]
Constant output of 60 Hz or more frequency with a constant-
torque (100%). The value obtained by the 3-wattmeter
method with a 4-pole 3.7 kW induction motor is assumed to
be 100%.

5.2.2Measurement of voltages and use of PT
Converter unit (FR-CC2-C) input side
As the input side voltage has a sine wave and it is extremely small in distortion, accurate measurement can be made with an
ordinary AC meter.
Inverter output side
Since the output side voltage has a PWM-controlled rectangular wave, always use a rectifier type voltmeter. A needle type
tester cannot be used to measure the output side voltage as it indicates a value much greater than the actual value. A moving-
iron type meter indicates an effective value which includes harmonics and therefore the value is larger than that of the
fundamental wave. The value monitored on the operation panel is the inverter-controlled voltage itself. Hence, that value is
accurate and it is recommended to monitor values (analog output) using the operation panel.
PT
No PT can be used in the output side of the inverter. Use a direct-reading meter. (A PT can be used in the input side of the
converter unit (FR-CC2-C).)

5.2.3Measurement of currents
Use moving-iron type meter on the input side of the converter unit (FR-CC2-C) and the output side of the inverter. However, if
the carrier frequency exceeds 5 kHz, do not use that meter since an overcurrent losses produced in the internal metal parts of
the meter will increase and the meter may burn out. In this case, use an approximate-effective value type.
Since current on the converter unit input side tends to be unbalanced, measurement of three phases is recommended.
Correct value cannot be obtained by measuring only one or two phases. On the other hand, the unbalanced ratio of each
phase of the output side current should be within 10%.
When a clamp ammeter is used, always use an effective value detection type. A mean value detection type produces a large
error and may indicate an extremely smaller value than the actual value. The value monitored on the operation panel is
accurate if the output frequency varies, and it is recommended to monitor values (provide analog output) using the operation
panel.
Examples of measured value differences produced by different measuring meters are shown below.

Indicated value of the moving-iron type ammeter is 100%.

5.2.4Use of CT and transducer
A CT may be used in both the input side of the converter unit and the output side of the inverter. Use the one with the largest
possible VA ability because an error will increase if the frequency gets lower.
When using a transducer, use the effective value calculation type which is immune to harmonics.

5.2.6Measurement of converter output voltage
(across terminals P and N)
The output voltage of the converter is output across terminals P and N and can be measured with a moving-coil type meter
(tester). Although the voltage varies according to the power supply voltage, approximately 800 to 900 V is output when no
load is connected and voltage decreases during driving load operation.
When energy is regenerated from the motor during deceleration, for example, the converter output voltage rises to nearly
1100 to 1300 V maximum.

5.2.7Measurement of inverter output frequency
In the initial setting, a pulse train proportional to the output frequency is output across the analog current output terminals CA
and 5 of the inverter. Measure the current using an ammeter or tester.
For detailed specifications of the analog current output terminal CA, refer to the FR-F860 Instruction Manual (Detailed).
5.2.8Insulation resistance test using megger
• For the inverter and the converter unit (FR-CC2-C), conduct the insulation resistance test on the main circuit only as shown
below and do not perform the test on the control circuit. (Use a 500 VDC megger.)
• Before performing the insulation resistance test on the external circuit, disconnect the cables from all terminals of the inverter
and the converter unit so that the test voltage is not applied to the inverter and the converter unit.
• For the continuity test of the control circuit, use a tester (high resistance range) and do not use the megger or buzzer.
5.2.9Pressure test
Do not conduct a pressure test. Deterioration may occur.
