In this Instruction Manual, the safety instruction levels are

classified into "WARNING" and "CAUTION"

Incorrect handling may cause

hazardous conditions, resulting in

death or severe injury.

Incorrect handling may cause

hazardous conditions, resulting in

medium or slight injury, or may cause

only material damage.

Note that even the level may even lead to

a serious consequence according to conditions. Be sure to

follow the instructions of both levels as they are critical to

personal safety.

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, as accidental contact with exposed

high-voltage terminals and internal components may occur,

resulting in an electrical 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, the 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 61140

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. Doing so may cause 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. Doing so may cause 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 high-

voltage 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.

WARNING

CAUTION

 Inverter must be installed on a nonflammable wall without holes

(so that nobody touches the inverter heat sink 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.

 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.

CAUTION

 The voltage applied to each terminal must be the ones specified

in the Instruction Manual. Otherwise an explosion or damage

may occur.

 The cables must be connected to the correct terminals.

Otherwise an explosion or damage may occur.

 The polarity (+ and -) must be correct. Otherwise an explosion or

damage 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.

CAUTION

CAUTION

Transportation and installation

 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.

 This product must be used at an altitude of 2500 m or less, with

5.9 m/s

or less vibration at 10 to 55 Hz (directions of X, Y, Z

axes). Otherwise the inverter may be damaged. (For the

installation at an altitude above 1000 m, consider a 3% reduction

in the rated current per 500 m increase in altitude.)

 If halogen-based materials (fluorine, chlorine, bromine, iodine,

etc.) infiltrate into a Mitsubishi Electric 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 Electric

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.

Test operation

 Before starting operation, each parameter must be confirmed

and adjusted. A failure to do so may cause some machines to

make unexpected motions.

WARNING

Usage

 Stay away from the equipment after using the retry function in

this product as the equipment will restart suddenly after the

output shutoff of this product.

 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. Doing so may shorten

the life of this product.

 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 600 V 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 before you

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.

 When the emergency drive operation is performed, the operation

is continued or the retry is repeated even when a fault occurs,

which may damage or burn the inverter and motor. Before

restarting the normal operation after using the emergency drive

function, make sure that the inverter and motor have no fault.

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 this product or an external device

controlling this product.

 When the breaker on the inverter input side trips, the wiring must

be checked for fault (short circuit), and internal parts 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

 For clarity, illustrations in this Instruction Manual may be drawn

with covers or safety guards removed. Ensure all covers and

safety guards are properly installed prior to starting operation.

For details on the PM motor, refer to the Instruction Manual of

the PM motor.

NOTE

• To prevent an electric shock, always earth (ground) the motor and inverter.

• Do not install a power factor correction capacitor or surge suppressor or capacitor type filter on the inverter's output side.

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. When installing a molded case circuit breaker on the output side of the inverter, contact

the manufacturer of the molded case circuit breaker.

• Electromagnetic wave interference

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. Refer to page 61 for countermeasures.

• For details of options and peripheral devices, refer to the respective Instruction Manual.

• A PM motor cannot be driven by the commercial power supply.

• A PM motor is a motor with permanent magnets embedded inside. High voltage is generated at the motor terminals while the

motor is running. Before closing the contactor at the output side, make sure that the inverter power is ON and the motor is

stopped.

Symbol Name Overview

Refer

to page

(a) Inverter (FR-F860)

The life of the inverter is influenced by the surrounding air temperature.

The surrounding air temperature should be as low as possible within the

permissible range. This must be noted especially when the inverter is

installed in an enclosure.

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.

23, 31

(b) Three-phase AC power supply Must be within the permissible power supply specifications of the inverter. 544

(c)

Molded case circuit breaker (MCCB),

earth leakage circuit breaker (ELB), or

fuse

Must be selected carefully since an inrush current flows in the inverter at

power ON.

18

(d) Magnetic contactor (MC)

Install this to ensure safety.

Do not use this to start and stop the inverter. Doing so will shorten the life

of the inverter.

64

(e) AC reactor

Install this to suppress harmonics and to improve the power factor.

An AC reactor is required when installing the inverter near a large power

supply system (1000 kVA or more). Under such condition, the inverter

may be damaged if you do not use a reactor.

Select a reactor according to the applied motor capacity.

63

(f) DC reactor

Install this to suppress harmonics and to improve the power factor.

Select a reactor according to the applicable motor capacity.

For the FR-F860-01080 or higher, or a motor with a capacity of 75 kW or

higher, always connect a DC reactor.

When using the DC reactor with the FR-F860-00680 or lower, remove the

jumper across terminals P/+ and P1 before connecting the DC reactor to

the inverter.

63

(g) Noise filter Suppresses the noise radiated from the power supply side of the inverter. 61

(h) USB connection

A USB (Ver. 1.1) cable connects the inverter with a personal computer.

A USB memory device enables parameter copies and the trace function.

55

(i) Noise filter

Install this to reduce the electromagnetic noise generated from the

inverter. The noise filter is effective in the range from about 0.5 MHz to 5

MHz.

A wire should be wound four turns at maximum.

61

(j) Induction motor Connect a squirrel-cage induction motor. 

(k)

Contactor

Example) No-fuse switch (DSN type)

Connect this for an application where a PM motor is driven by the load

even while the inverter power is OFF. Do not open or close the contactor

while the inverter is running (outputting).



(l) PM motor

A PM motor can be used. A PM motor cannot be driven by the

commercial power supply.



Peripheral devices

INSTALLATION AND WIRING

2.1.2 Peripheral devices

Check the model of the inverter you purchased. Appropriate peripheral devices must be selected according to the capacity.

Refer to the table below to prepare appropriate peripheral devices.

SLD rating (Pr.570 Multiple rating setting = "0")

NOTE

• When the inverter capacity is larger than the motor capacity, select an MCCB and a magnetic contactor according to the

inverter model, and select cables and reactors according to the motor output.

• When the breaker on the inverter's input side trips, check for the wiring fault (short circuit), damage to internal parts of the

inverter etc. The cause of the trip must be identified and removed before turning ON the power of the breaker.
