Incorrect handling may cause hazardous conditions, resulting in medium or slight injury, or may cause only material damage.
level may even lead to a serious consequence according to conditions. Both instruction levels must be followed because these are important to personal safety.
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, LCD indication of the operation panel 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 61140 class 1 and other applicable standards). A neutral-point earthed (grounded) power supply in compliance with EN standard must be used.
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.
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.
When measuring the main circuit capacitor capacity, the DC voltage is applied to the motor for 1s at powering OFF.
Never touch the motor terminal, etc. right after powering
OFF to prevent 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.
Resistors cannot be used. Do not connect a resistor directly to the DC terminals P/+ and N/-. Doing so could 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.

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 ambient temperature must be between -10 and +40°C
(non-freezing). Otherwise the inverter may be damaged.
The ambient humidity must be 95%RH or less (noncondensing). Otherwise the inverter may be damaged.
(Refer to page 18 for details.)
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,
with vibration at 5.9 m/s or less, 10 to 55 Hz (directions of
X, Y, Z axes). Otherwise the inverter may be damaged. (For the installation at an altitude above 1,000 m, derate the rated current 3% per 500 m.)
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.
2.9 m/s 2 or less for the FR-F846-01800(75K) or higher.
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.
2
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 400V 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 for devices or equipment in a system to prevent hazardous conditions in case of failure of the inverter or an external device controlling the inverter.
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.
General instruction
Many of the diagrams and drawings in the Instruction
Manual show the product without a cover or partially open for explanation. Never operate the product in this manner.
The cover must be always reinstalled and the instruction in the Instruction Manual must be followed when operating the product. For more details on the PM motor, refer to the
Instruction Manual of the PM motor.
Caution
Waterproof and dustproof performances
The inverter is rated with an IPX5
waterproof rating and an
IP5X dustproof rating when the operation panel (FR-DU08-
01), the front cover, the wiring cover, and the cable glands are securely fixed with screws.
The items enclosed with the inverter such as the Instruction
Manual or CD are not rated with the IPX5 waterproof or IP5X dustproof ratings.
Although the inverter is rated with the IPX5 waterproof and
IP5X dustproof ratings, it is not intended for use in water.
Also, the ratings do not guarantee protection of the inverter from needless submersion in water or being washed under strong running water such as a shower.
Do not pour or apply the following liquids over the inverter: water containing soap, detergent, or bath additives; sea water; swimming pool water; warm water; boiling water; etc.
The inverter is intended for indoor
installation and not for outdoor installation. Avoid places where the inverter is subjected to direct sunlight, rain, sleet, snow, or freezing temperatures.
If the operation panel (FR-DU08-01) is not installed, if the screws of the operation panel are not tightened, or if the operation panel is damaged or deformed, the IPX5 waterproof performance and the IP5X dustproof performance are impaired. If any abnormalities are found on the operation panel, ask for an inspection and repair.
If the screws of the front cover or the wiring cover are not tightened, if any foreign matter (hair, sand grain, fiber, etc.) is stuck between the inverter and the gasket, if the gasket is damaged, or if the front cover or the wiring cover is damaged or deformed, the IPX5 waterproof performance and the IP5X dustproof performance are impaired. If any abnormalities are found on the front cover, wiring cover, or the gasket of the inverter, ask for an inspection and repair.
Cable glands are important components to maintain the waterproof and dustproof performances. Be sure to use cable glands of the recommended size and shape or equivalent. The standard protective bushes cannot sufficiently maintain the IPX5 waterproof performance and the IP5X dustproof performance.
If a cable gland is damaged or deformed, the IPX5 waterproof performance and the IP5X dustproof performance are impaired. If any abnormalities are found on the cable glands, ask the manufacturer of the cable glands for an inspection and repair.
To maintain the waterproof and dustproof performances of the inverter, daily and periodic inspections are recommended regardless of the presence or absence of abnormalities.
IPX5 refers to protection of the inverter functions against water jets from any direction when about 12.5-liter water
is injected from a nozzle with an inside diameter of 6.3 mm from the distance of about 3 m for at least 3 minutes.
IP5X refers to protection of the inverter functions and maintenance of safety when the inverter is put into a stirring device containing dust of 75
µm or smaller in diameter, stirred for 8 hours, and then removed from the device.
Water here refers to fresh water at room temperature (5 to 35°C).
Indoor here refers to the environments that are not affected by climate conditions.

Overview
Refer to page
The life of the inverter is influenced by the ambient temperature.
The ambient temperature should be as low as possible within the permissible range.
Incorrect wiring may lead to damage of the inverter. The control signal lines must be kept fully away from the main circuit lines to protect them from noise.
The built-in EMC filter can reduce the noise.
In this inverter, a DC reactor and common mode choke are built in to suppress harmonics and to improve the power factor.
Must be within the permissible power supply specifications of the inverter.
Three-phase AC power supply

Installation of the inverter
2.3
Installation of the inverter
An inverter unit uses many semiconductor devices. To ensure higher reliability and long period of operation, operate the inverter in the ambient environment that completely satisfies the equipment specifications.
2.3.1
Inverter installation environment
The following table lists the standard specifications of the inverter installation environment. Using the inverter in an environment that does not satisfy the conditions deteriorates the performance, shortens the life, and causes a failure. Refer to the following points, and take adequate measures.

2.9 m/s 2 or less for the FR-F846-01160(55K) or higher.
5 cm
Temperature
The permissible ambient temperature of the inverter is between -10°C and +40°C. 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 ambient temperature of the inverter within the specified range.
(a) Measures against high temperature
• Ventilate the room.
• Install the inverter 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 inverter well.
(b) Measures against low temperature
• Provide a heater around the inverter.
• 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.
18
Installation of the inverter
Humidity
Operate the inverter within the ambient air humidity of usually 45 to 90%. 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
• Provide dry air into the room from outside.
• Use a dehumidifier.
(b) Measures against low humidity
Air with proper humidity can be blown into the room 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-room 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 faults such as poor contacts, reduction in insulation and cooling effect due to accumulation of moisture-absorbed dust and dirt, and equipment internal temperature rise due to a clogged ventilation filter in the room where the equipment is installed. 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
• 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 a place, take the countermeasures described in "Dust, dirt, oil mist" 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 2500 m. For the installation at an altitude above 1,000 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 5.9 m/s
2
(2.9 m/s
2
or less for the FR-F846-01800(75K) or higher) at 10 to 55
Hz frequency and 1 mm amplitude for the directions of X, Y, Z axes. Applying vibration and impacts for a long time may loosen the structures and cause poor contacts of connectors, 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
• Strengthen the structure to prevent the installation surface from resonance.
• Install the inverter away from the sources of the vibration.

Installation of the inverter
2.3.2
Inverter installation
Inverter placement
• Install the inverter on a strong flat surface securely with screws.
Fix six positions for the FR-F846-01800(75K) or higher.
• 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.
• For heat dissipation and maintenance, keep clearance between the inverter and the other devices. The clearance below the inverter is required as a wiring space, and the clearance above the inverter is required as a heat dissipation space.

Use a larger diameter cable when the wiring distance is long or when it is desired to decrease the voltage drop (torque reduction) in the low speed range.
NOTE
• 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 crimping terminals with insulation sleeves to wire the power supply and motor.

NOTE
• Especially for long-distance wiring or wiring with shielded cables, the inverter may be affected by a charging current caused by stray capacitances of the wiring, leading to an activation of the overcurrent protection, malfunction of the fast-response current limit operation, or even to an inverter failure. It may also cause a malfunction or fault of the equipment connected ON the inverter output side. Stray capacitances of the wiring differ by the installation condition, use the total wiring length in the table above as reference values. If the fast-response current limit function malfunctions, disable this function. (Refer to Pr.156
Stall prevention operation selection on the FR-F800 Instruction Manual (Detailed).)
• A surge voltage suppression filter (FR-ASF-H/FR-BMF-H) can be used under V/F control and Advanced magnetic flux vector control. A sine wave filter (MT-BSL/BSC) can be used under V/F control. Do not use the filters under different control methods.

Earthing (grounding) precautions
Always earth (ground) the motor and inverter.
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 noiseinfluenced 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.
• This inverter must be earthed (grounded). Earthing (Grounding) must conform to the requirements of national and local safety regulations and electrical codes. (NEC section 250, IEC 61140 class 1 and other applicable standards).
A neutral-point earthed (grounded) power supply in compliance with EN standard must be used.
• Use the thickest possible earthing (grounding) cable. The earthing (grounding) cable should be the size indicated in the table on
• 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.

Turn ON the RT signal to enable the second function.
When the second function such as "second torque boost" and
"second V/F (base frequency)" is set, turning ON the RT signal enables the selected function.
Turn ON the MRS signal (20ms or more) to stop the inverter output.
Use this signal to shut off the inverter output when stopping the motor with an electromagnetic brake.
Use this signal to reset a fault output provided when a protective function is activated. Turn ON the RES signal for 0.1 s or longer, then turn it OFF.
In the initial setting, reset is set always-enabled. By setting Pr.75
, reset can be set enabled only at fault occurrence. The inverter recovers about 1 s after the reset is released.
The terminal 4 function is available only when the AU signal is turned ON.
Turning the AU signal ON makes terminal 2 invalid.

• Power supply connection
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.
Cable stripping size
10 mm
(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.

Wiring precautions
• It is recommended to use a cable of 0.3 to 0.75 mm
2
for the connection to the control circuit terminals.
• The wiring length should be 30 m (200 m for terminal FM) 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 microcurrents.
• 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 200 V relay
Micro signal contacts Twin contacts 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 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.

When supplying 24 V external power to the control circuit
Connect a 24 V external power supply across terminals +24 and SD. Connecting a 24 V external power supply enables I/O terminal ON/OFF operation, operation panel displays, control functions, and communication during communication operation even at power-OFF of inverter's main circuit power supply. When the main circuit power supply is turned ON, the power supply source changes from the 24 V external power supply to the main circuit power supply.

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
. (For the details of Pr.30
, refer to the FR-F800 Instruction Manual (Detailed).))
Confirming the 24 V external power supply input
• During the 24 V external power supply operation, the 24 V external power supply operation (EV) signal 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.

Control circuit
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 panel is enabled) using the operation panel keys.
• The safety stop function is invalid during the 24 V external power supply operation.
• During the 24 V external power supply operation, monitored items and signals related to inputs to main circuit power supply, such as output current and converter output voltage are invalid.
• The faults, which have occurred 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.
• If the power supply changes from the main circuit power supply to the 24 V external power supply while measuring the main circuit capacitor's life, the measurement completes after the power supply changes back to the main circuit power supply
( Pr.259 = "3").
• The output data is retained when "1 or 11" is set in Pr.495 Remote output selection .
NOTE
• 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 and 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. When connecting different inverters to different power supplies, use the inverters after confirming that the input voltage of each inverter is within the rated input voltage range.
Depending on the power supply, the over current protection may be activated and 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 external power supply operation.
• "E.P24" may appear when the 24 V external power supply input voltage is low. Check the external power supply input.
• Do not touch the control circuit terminal block (circuit board) during the 24 V power supply operation (when conducted).
Otherwise you may get an electric shock or burn.

Electro-magnetic interference (EMI) and leakage currents
3.1
Electro-magnetic interference (EMI) and leakage currents
3.1.1
Leakage 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.
Suppression technique
• 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. When the wiring length is long (50 m or more) for small-capacity models (FR-F846-00170(7.5K) or lower), the external thermal relay is likely to operate unnecessarily because the ratio of the leakage current to the rated motor current increases.

PRECAUTIONS FOR USE OF THE INVERTER
Electro-magnetic interference (EMI) and leakage currents
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.) As an earth leakage current breaker, use the Mitsubishi earth leakage current breaker designed for harmonics and surge suppression.
Selecting the rated sensitivity current for the earth leakage circuit breaker
When using an earth leakage circuit breaker with the inverter circuit, select its rated sensitivity current as follows, independently of the PWM carrier frequency.
• Breaker designed for harmonic and surge suppression
Rated sensitivity current
I n ≥ 10 (Ig1 + Ign + Igi + Ig2 + Igm)
• Standard breaker

Electro-magnetic interference (EMI) and leakage currents
NOTE
• Install the earth leakage circuit breaker (ELB) on the input side of the inverter.
• In the connection earthed-neutral system, the sensitivity current is blunt against a ground fault in the inverter output side.
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)
• When the breaker is installed on the output side of the inverter, it may be unnecessarily operated by harmonics even if the effective value is within the rating.
In this case, do not install the breaker since the eddy current and hysteresis loss will increase, leading to temperature rise.
• The following models are standard breakers: BV-C1, BC-V, NVB, NV-L, NV-G2N, NV-G3NA, NV-2F, earth leakage relay
(except NV-ZHA), and NV with AA neutral wire open-phase protection. The other models are designed for harmonic and surge suppression: NV-C/NV-S/MN series, NV30-FA, NV50-FA, BV-C2, earth leakage alarm breaker (NF-Z), NV-ZHA, and
NV-H.
3.1.2
Countermeasures against inverter-generated
EMI
Some electromagnetic noises enter the inverter to cause the inverter malfunction, and others are radiated by the inverter to cause the peripheral devices to malfunction. Though the inverter 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 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, motor, etc. at one point.
• Techniques to reduce electromagnetic noises that enter and cause a malfunction of the inverter (EMI countermeasures)
When devices that generate many electromagnetic noises (which use magnetic contactors, electromagnetic brakes, many relays, for example) are installed near the inverter and the inverter may malfunction due to electromagnetic noises, the following countermeasures must be taken:
- Provide surge suppressors fordevices that generate many electromagnetic noises to suppress electromagnetic noises.
- Install data line filters ( page 63 ) 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 to cause the peripheral devices to malfunction (EMI countermeasures)
Inverter-generated noises are largely classified into those radiated by the cables connected to the inverter and inverter 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.

When devices that handle low-level signals and are liable to malfunction due to electromagnetic noises, e.g. instruments, receivers and sensors, are near the inverter or when the 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.
• Run easily affected signal cables as far away as possible from the inverter and its I/O cables.
• Do not run the signal cables and power cables (inverter I/O cables) in parallel with each other and do not bundle them.
• Set the EMC filter ON/OFF connector of the inverter to the ON position. (Refer to page 64 .)
• 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.
• Run easily affected signal cables as far away as possible from the inverter and its I/O cables.
• Do not run the signal cables and power cables (inverter 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 in the same line, inverter-generated noises may flow back through the power supply cables to cause malfunction of the devices and the following countermeasures must be taken:
• Set the EMC filter ON/OFF connector of the inverter to the ON position. (Refer to page 64 .)
• Install the line noise filter (FR-BLF, FR-BSF01) 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, leakage currents may flow through the earthing (grounding) cable of the inverter 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.

Built-in EMC filter
This inverter is equipped with a built-in EMC filter (capacitive filter) and a common mode choke.
These filters are effective in reducing air-propagated noise on the input side of the inverter.
To enable the EMC filter, fit the EMC filter ON/OFF connector to the ON position.The EMC filter is initially set to the "enabled"
(ON) position.
The input side common mode choke, which is built in the inverter, is always enabled regardless of the EMC filter ON/OFF connector setting.

Harmonic suppression guidelines in Japan
Inverters have a converter section (rectifier circuit) and generate a harmonic current.
Harmonic currents flow from the inverter to a power receiving point via a power transformer. The Harmonic Suppression
Guidelines was established to protect other consumers from these outgoing harmonic currents.
The three-phase 200 V input specifications 3.7 kW or lower were previously covered by "the Harmonic Suppression
Guidelines for Household Appliances and General-purpose Products" and other models were covered by "the Harmonic
Suppression Guidelines for Consumers Who Receive High Voltage or Special High Voltage". However, the transistorized inverter has been excluded from the target products covered by "the Harmonic Suppression Guidelines for Household
Appliances and General-purpose Products" in January 2004 and "the Harmonic Suppression Guideline for Household
Appliances and General-purpose Products" was repealed on September 6, 2004.
All capacity and all models of general-purpose inverter used by specific consumers are now covered by "the Harmonic
Suppression Guidelines for Consumers Who Receive High Voltage or Special High Voltage" (hereinafter referred to as "the
Specific Consumer Guidelines").
• "Specific Consumer Guidelines"
This guideline sets forth the maximum harmonic currents outgoing from a high-voltage or especially high-voltage receiving consumer who will install, add or renew harmonic generating equipment. If any of the maximum values is exceeded, this guideline requires that consumer to take certain suppression measures.

• Calculation of equivalent capacity P0 of harmonic generating equipment
"Equivalent capacity" is the capacity of a 6-pulse converter converted from the capacity of consumer's harmonic generating equipment and is calculated by the following equation: If the sum of equivalent capacities is higher than the limit (Refer to
), harmonics must be calculated with the following procedure:
P0 = ∑ (Ki Pi) [kVA]
Ki: Conversion coefficient (Refer to
Pi: Rated capacity of harmonic generating equipment
i: Number indicating the conversion circuit type
Rated capacity: Determined by the capacity of the applied motor and found in Table 5. The rated capacity used here is used to calculate the generated harmonic amount and is different from the power supply capacity required for actual inverter drive.

Installation of a reactor
• Determining if a countermeasure is required
A countermeasure for harmonics is required if the following condition is satisfied: outgoing harmonic current > maximum value per 1 kW contract power contract power
• Harmonic suppression techniques
No.

Item
Reactor installation
(FR-HAL)
High power factor converter (FR-HC2)
Description
Because a DC reactor is built in on the DC side of this product, outgoing harmonic current can be suppressed. By installing an AC reactor (FR-HAL) on the AC side of the inverter, the outgoing harmonic current suppression performance can be improved.
This converter trims the current waveform to be a sine waveform by switching the rectifier circuit
(converter module) with transistors. Doing so suppresses the generated harmonic amount significantly.
Connect it to the DC area of an inverter. Use the high power factor converter (FR-HC2) with the accessories that come as standard.
3
Installation of power factor improving capacitor
When used with a reactor connected in series, the power factor improving correction capacitor can absorb harmonic currents.
4
5
Transformer multi-phase operation
Passive filter
(AC filter)
Use two transformers with a phase angle difference of 30 ˚ as in ∆ and ∆ ∆ combinations to provide an effect corresponding to 12 pulses, reducing low-degree harmonic currents.
A capacitor and a reactor are used together to reduce impedances at specific frequencies. Harmonic currents are expected to be absorbed greatly by using this technique.
6 Active filter
This filter detects the current in a circuit generating a harmonic current and generates a harmonic current equivalent to a difference between that current and a fundamental wave current to suppress the harmonic current at the detection point. Harmonic currents are expected to be absorbed greatly by using this technique.
3.3
Installation 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 optional AC reactor (FR-HAL).

PRECAUTIONS FOR USE OF THE INVERTER
Power-OFF and magnetic contactor (MC)
3.4
Power-OFF and magnetic contactor (MC)
Inverter input side magnetic contactor (MC)
On the inverter input side, it is recommended to provide an MC for the following purposes:
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.). For example, an MC prevents overheat or burnout of the brake resistor when heat capacity of the resistor is insufficient or brake regenerative transistor is damaged with short while connecting an optional brake resistor.
• 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 motor driving, select an MC regarding the inverter input side current as JEM1038-
AC-3 class rated current.
NOTE
• 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.

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 commercial power supply-inverter switchover function Pr.135 to Pr.139
(Refer to the FR-F800 Instruction Manual (Detailed)). (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.
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).

Countermeasures against deterioration of the 400 V class motor insulation
3.5
Countermeasures against deterioration of the 400 V class motor insulation
In the PWM type inverter, a surge voltage attributable to wiring constants is generated at the motor terminals. Especially in a
400 V class motor, the surge voltage may deteriorate the insulation. When the 400 V class motor is driven by the inverter, consider the following countermeasures:
Countermeasures for induction motors
It is recommended to take one of the following countermeasures:
Rectifying the motor insulation and limiting the PWM carrier frequency according to the wiring length
For the 400 V class motor, use an insulation-enhanced motor.
Specifically,
• Order a "400 V class inverter-driven insulation-enhanced motor".
• For the dedicated motor such as the constant-torque motor and low-vibration motor, use an "inverter-driven dedicated motor".
• Set Pr.72 PWM frequency selection as indicated below according to the wiring length.
50 m or shorter
Pr.72 PWM frequency selection 15 (14.5 kHz) or lower
Wiring length
50 m to 100 m
9 (9 kHz) or lower
Longer than 100 m
4 (4 kHz) or lower
Suppressing the surge voltage on the inverter side
• For the FR-F846-01160(55K) or lower, connect the surge voltage suppression filter (FR-ASF-H/FR-BMF-H) to the output side.
• For the FR-F846-01800(75K) or higher, connect the sine wave filter (MT-BSL/BSC) to the output side.
Countermeasures for PM motors
• When the wiring length exceeds 50 m, set "9" (6 kHz) or less in Pr.72 PWM frequency selection .
NOTE
• For the details of Pr.72 PWM frequency selection , refer to the FR-F800 Instruction Manual (Detailed).
• For the details of the surge voltage suppression filter (FR-ASF-H/FR-BMF-H), refer to the Instruction Manual of each option.
• A surge voltage suppression filter (FR-ASF-H/FR-BMF-H) can be used under V/F control and Advanced magnetic flux vector control.
A sine wave filter (MT-BSL/BSC) can be used under V/F control. Do not use the filters under different control modes.

PRECAUTIONS FOR USE OF THE INVERTER
Checklist before starting operation
3.6
Checklist before starting operation
The FR-F800 series inverter is a highly reliable product, but incorrect peripheral circuit making or operation/handling method may shorten the product life or damage the product.
Before starting operation, always recheck the following points.
Checkpoint Countermeasure
Refer to page
Check by user
Crimping terminals are insulated.
Use crimping terminals with insulation sleeves to wire the power supply and the motor.
-
The wiring between the power supply (R/L1, S/L2, T/L3) and the motor (U, V, W) is correct.
Application of power to the output terminals (U, V, W) of the inverter will damage the inverter. Never perform such wiring.
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.
Wire offcuts can cause an alarm, failure or malfunction. Always keep the inverter clean.
When drilling mounting holes in a wall etc., take caution not to allow chips and other foreign matters to enter the inverter.
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 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 includes high frequency components, which may interfere with the communication devices (such as
AM radios) used near the inverter. In such case, activate the EMC filter (turn
ON the EMC filter ON/OFF connector) to minimize interference.
-
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.
Such installation 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.
-
-
The inverter's output side has no short circuit or ground fault occurring.
The circuit is not configured to use the inverter's input-side magnetic contactor to start/stop the inverter frequently.
The voltage applied to the inverter
I/O signal circuits is within the specifications.
When using the electronic bypass operation, electrical and mechanical interlocks are provided between the electronic bypass contactors MC1 and MC2.
For some 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 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 a 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, make sure to check the motor insulation resistance, etc.
Since repeated inrush currents at power ON will shorten the life of the converter circuit, 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.
Application of a voltage higher than the permissible voltage to the inverter I/O signal circuits or opposite polarity may damage the I/O devices. Especially check the wiring to prevent the speed setting potentiometer from being connected incorrectly to short circuit terminals 10E and 5.
When using a switching circuit as shown below, chattering due to misconfigured sequence or arc generated at switching may allow undesirable current to flow in and damage the inverter. Mis-wiring may also damage the inverter. (The commercial power supply operation is not available with PM motors.)

Countermeasure
Refer to page
If the machine must not be restarted when power is restored after a power failure, provide an MC in the inverter'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 inverter's input side, connect an MC for the following purposes:
• 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 motor driving, select an MC regarding the inverter 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.
When a failure occurs between the MC2 and motor, make sure to provide a protection circuit, such as using the OH signal input.
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 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 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 I/O cables).
• Use shielded cables.
• Install a ferrite core on the signal cable (Example: ZCAT3035-1330 by TDK).
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 an inverter of a higher capacity (up to two ranks).
For a PM motor, use an inverter and PM motor of higher capacities.
Make sure that the specifications and rating match the system requirements.
When a motor is driven by the inverter, axial voltage is generated on the motor bearing, which may cause electrical corrosion of the bearing in rare cases depending on: condition of the grease used for the bearing, wiring, load, operating conditions of the motor, or specific inverter settings (high carrier frequency, built-in EMC filter ON).
Contact your sales representative to take appropriate countermeasures for the motor.
The following shows examples of countermeasures for the inverter.
• Decrease the carrier frequency.
• Turn OFF the built-in EMC filter.
• Provide a common mode choke
on the output side of the inverter. (This is effective regardless of the EMC filter ON/OFF connector setting.)
Recommended common mode choke: FT-3KM F series FINEMET ® common mode choke cores manufactured by Hitachi Metals, Ltd.

PRECAUTIONS FOR USE OF THE INVERTER
Failsafe system which uses the inverter
3.7
Failsafe 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.

• Changing the terminal assignment using Pr.190 to 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-F800 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, start, 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.

Checking the inverter and converter modules
Preparation
• Disconnect the external power supply cables (R/L1, S/L2, T/L3) and motor cables (U, V, W).
• Prepare a tester. (For the resistance measurement, use the 100 Ω range.)
Checking method
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.
NOTE
• 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 Ω to several tens of Ω . 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.

Life display of internal air circulation fans
• IP55 compatible models are equipped with the internal air circulation fan inside the inverter other than the cooling fan.
The internal fan fault "FN2" appears on the operation panel (FR-LU08-01) when the rotations per minute is less than
70% of the rated value for the internal air circulation fan. (FN is displayed on the parameter unit (FR-PU07).) As an alarm display, Pr.255 bit 4 is turned ON and also a warning is output to the Y90 signal and Alarm (LF) signal.
• For the terminal used for the LF signal, set "98 (positive logic) or 198" (negative logic) in any of Pr.190 to Pr.196
(Output terminal function selection) .
NOTE
• Changing the terminal assignment using Pr.190 to Pr.196 (Output terminal function selection) may affect the other functions. Set parameters after confirming the function of each terminal.
• For replacement of each part, contact the nearest Mitsubishi Electric FA center.
Replacement procedure of the 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 ambient temperature. When unusual noise and/or vibration are noticed during inspection, the cooling fan must be replaced immediately.
NOTE
• Switch the power OFF before replacing fans. Even after the power supply is shut off, the inverter is charged and can cause an electric shock. Before replacing the fan, make sure to check that the voltage across inverter main circuit terminals P/+ and
N/- has been dropped enough using a tester after 10 minutes or more after the power supply shutoff.

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 ambient 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.
102
NOTE
• The inverter diagnoses the main circuit capacitor and control circuit capacitor by itself and can judge their lives. (Refer to the
FR-F800 Instruction manual (Detailed).)
PRECAUTIONS FOR MAINTENANCE AND INSPECTION
Inspection item
Relay output terminals
• 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 between the relay output terminals C1 and B1 or A1, or terminals C2 and B2 or A2. (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 36
.))
5.1.7
Precautions for removal and reinstallation of the control circuit terminal block
The FR-F800 series inverter has a removable control circuit terminal block, which can be replaced with a new one or a control terminal option. The following are the precautions to remove or reinstall the control circuit terminal block.
Observe the following for proper handling to avoid malfunctions or failures of the inverter.
• To remove or reinstall the control circuit terminal block, keep it upright so that it is parallel with the inverter.
• To install the control circuit terminal block, slide it upward so that the groove on the terminal block fits over the tongue on the inverter.
• Check that the terminal block is parallel with the inverter and the pins of the inverter's control circuit connector are not bent.
After checking the proper connection, fix the terminal block with two screws.
Fit the groove over the tongue.
Fasten the screws.

Measurement of main circuit voltages, currents, and powers
5.2
Measurement 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.
NOTE
• When installing meters etc. on the inverter output side
When the inverter-to-motor wiring length is large, especially small-capacity models, 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
FM/CA output functions of the inverter.

Measurement of main circuit voltages, currents, and powers
5.2.1
Measurement of powers
Use digital power meters (for inverter) for the both of inverter input and output side. Alternatively, measure using electrodynamic type single-phase wattmeters for the both of inverter input and output side in two-wattmeter or threewattmeter method. As the current is liable to be imbalanced especially in the input side, it is recommended to use the threewattmeter 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 threewattmeter 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 3wattmeter method with a 4-pole 3.7 kW induction motor is assumed to be 100%.

Measurement of voltages and use of PT
Inverter 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 movingiron 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 inverter.)
106
PRECAUTIONS FOR MAINTENANCE AND INSPECTION
Measurement of main circuit voltages, currents, and powers
5.2.3
Measurement of currents
Use moving-iron type meters on both the input and output sides 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 inverter 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.

Use of CT and transducer
A CT may be used in both the input and output sides 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.

Measurement 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 540 VDC to 600 VDC 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 800
VDC to 900 VDC maximum.

5.2.7
Measurement of inverter output frequency
In the initial setting of the FM-type inverter, a pulse train proportional to the output frequency is output across the pulse train output terminals FM and SD of the inverter. This pulse train output can be counted by a frequency counter, or a meter
(moving-coil type voltmeter) can be used to read the mean value of the pulse train output voltage. When a meter is used to measure the output frequency, approximately 5 VDC is indicated at the maximum frequency.
For detailed specifications of the pulse train output terminal FM, refer to the FR-F800 Instruction Manual (Detailed).
In the initial setting of the CA-type inverter, 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-F800 Instruction Manual (Detailed).
5.2.8
Insulation resistance test using megger
For the inverter, 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.)
NOTE
• Before performing the insulation resistance test on the external circuit, disconnect the cables from all terminals of the inverter so that the test voltage is not applied to the inverter.
• For the continuity test of the control circuit, use a tester (high resistance range) and do not use the megger or buzzer.

When a value 50% of the inverter rated output current (current value) is set in Pr.9
The % value denotes the percentage to the inverter rated current. It is not the percentage to the rated motor current.
When you set the electronic thermal relay function dedicated to the Mitsubishi Electric constant-torque motor, this characteristic curve applies to operation at 6 Hz or higher.
Transistor protection is activated depending on the temperature of the heatsink. The protection may be activated even with less than 120% depending on the operating conditions.
NOTE
• The internal accumulated heat value of the electronic thermal relay function is reset by inverter power reset and reset signal input. Avoid unnecessary reset and power-OFF.
• When multiple motors are driven with a single inverter or when a multi-pole motor or a special motor is driven, install an external thermal relay (OCR) between the inverter and motors. Note that the current indicated on the motor rating plate is affected by the line-to-line leakage current (refer to
) when selecting the setting for an external thermal relay.
• The cooling effect of the motor drops during low-speed operation. Use a thermal protector or a motor with built-in thermistor.
• When the difference between the inverter and motor capacities is large and the setting is small, the protective characteristics of the electronic thermal relay function will be deteriorated. In this case, use an external thermal relay.
• A special motor cannot be protected by the electronic thermal relay function. Use an external thermal relay.
• Motor over temperature sensing is not provided by the drive.

*3 When the electronic thermal relay function dedicated to the
Mitsubishi Electric constant-torque motor is set, this characteristic curve applies to operation at 6 Hz or higher.
*4 Transistor protection is activated depending on the temperature of the heatsink. The protection may be activated even with less than
150% depending on the operating conditions.
NOTE
• The internal accumulated heat value of the electronic thermal O/L relay is reset to the initial value by the inverter's power reset or reset signal input. Avoid unnecessary reset and power-OFF.
• When multiple motors are driven with a single inverter or when a multi-pole motor or a special motor is driven, install an external thermal relay (OCR) between the inverter and motors. When setting an external thermal relay, note that the current indicated on the motor rating plate is affected by the line-to-line leakage current. (Refer to the Instruction
Manual (Detailed).)
• The cooling effect of the motor drops during low-speed operation. Use a thermal protector or a motor with built-in thermistor.
• When the difference between the inverter and motor capacities is large and the set value is small, the protective characteristics of the electronic thermal relay function will be deteriorated. In such case, use an external thermal relay.
• A special motor cannot be protected by the electronic thermal relay function. Use an external thermal relay.
• Motor over temperature sensing is not provided by the electronic thermal O/L relay.
• Electronic thermal memory retention function is not provided by the drive.

setting can be changed during operation. The new setting is applied after stop. Until the inverter has stopped, the previous setting of the interface for the operation command and the speed command in the Network operation mode is valid.
Precautions for electronic bypass sequence function
• The response time of the inverter to the signals depends on the command source, NET or External.
After the communication with the inverter is established, the motor operation is performed according to the command via NET.
The commercial power supply operation with the motor is performed when the MRS signal turns ON before the communication is established. It is recommended to turn the MRS signal ON after the communication is established.
Example: the response time of the inverter to the signals in the Network operation mode (power-ON). The command source is
External for the MRS signal and NET for the STF (STR) and CS signals.

Display estimated main circuit capacitor residual life (Pr.506)
• The estimated residual life of the main circuit capacitor is displayed in Pr.506
.
• The remaining life of the main circuit capacitor is calculated from the energization time and the inverter output power (100% =
Start of service life). When the remaining life of the main circuit capacitor falls below 10%, bit 5 of Pr.255 Life alarm status display turns ON and a warning is output by the Y90 signal.
Life alarm display and signal output (Y90 signal, Pr.255)
• Power no longer needs to be turned OFF for the warning signal (Y90) to be output when using the main circuit residual-life estimation function.
• Whether or not the parts of the control circuit capacitor, main circuit capacitor, cooling fan, inrush current limit circuit or internal air circulation fans have reached the life alarm output level can be checked with Pr.255 Life alarm status display and the Life alarm (Y90) signal.

• The Life alarm (Y90) signal turns ON when either the control circuit capacitor life, main circuit capacitor life, cooling fan life, inrush current limit circuit life, internal air circulation fan life or the estimated residual life of the main circuit capacitor reaches the level set to output the life alarm.
• For the terminal used for the Y90 signal, set "90" (positive logic) or "190" (negative logic) in any of Pr.190 to Pr.196 (Output terminal function selection) .
NOTE
• When using an option (FR-A8AY, FR-A8AR, FR-A8NC, FR-A8NCE), the life alarm for the Control circuit capacitor life (Y86 signal), Main circuit capacitor life (Y87 signal), Cooling fan life (Y88 signal), Inrush current limit circuit life
(Y89 signal), and the estimated residual-life of the Main circuit capacitor (Y248 signal) can be output individually.
• Changing the terminal assignment using Pr.190 to Pr.196 (Output terminal function selection) may affect the other functions. Set parameters after confirming the function of each terminal.

NOTE
• When the main circuit capacitor life is measured under the following conditions, "forced end" ( Pr.259
= "8, 18"), or
"measurement error" ( Pr.259
= "9, 19") may occur, or the status may remain in "measurement start" ( Pr.259
= "1,

"measurement complete" ( Pr.259
= "3, 13") is reached, measurement cannot be performed correctly.
FR-HC2, FR-CV, MT-RC, or a sine wave filter (MT-BSL/BSC) is connected.
Terminals R1/L11, S1/L21 or DC power supply is connected to terminals P/+ and N/-.
The power supply is switched ON during measurement.
The motor is not connected to the inverter.
The motor is running (coasting).
The motor capacity is smaller than the inverter capacity by two ranks or more.
The inverter output is shut off or a fault occurred while the power was OFF.
The inverter output is shut off with the MRS signal.
The start command is given while measuring.
The applied motor setting is incorrect.
• Operation environment: Surrounding air temperature (annual average of 40°C (free from corrosive gas, flammable gas, oil mist, dust and dirt)).
Output current: 80% of the inverter rating
• Since repeated inrush currents at power ON will shorten the life of the converter circuit, frequent starts and stops of the magnetic contactor must be avoided.
WARNING
• When measuring the main circuit capacitor capacity ( Pr.259
= "1, 11"), the DC voltage is applied to the motor for about 1 second at power OFF. Never touch the motor terminal, etc. right after powering OFF to prevent an electric shock.
