This section is specifically about safety matters

Do not attempt to install, op erate, maintain or inspect the
inverter until you have read through the Instruction Manual
(Basic) and appended documents carefully and can use the
equipment correctly. Do not use this product until you have
a full knowledge of the equipment, safety information and
instructions.
In this Instruction Manual (Basic), the safety instruction
levels are classified into "WARNING" and "CAUTION".

The level may even lead to a serious
consequence according to conditions. Both instruction
levels must be followed because these are important to
personal safety.

Incorrect handling may cause
hazardous conditions, resulting in
death or severe injury.

Incorrect handling may cause
hazardous conditions, resulting in
medium or slight inju ry, or may cause
only material damage.

1. Electric Shock Prevention

 While the inverter power is ON, do not remove t he front

cover or the wiring cover. Do not run the inverter with the
front cover or the wiring cover removed. Otherwise you
may access the exposed high voltage terminals or the
charging part of the circuitry and get an electric shock.

 Even if power is OFF, do not remove the front cover

except for wiring or periodic inspection. You may
accidentally touch the charged inverter circuits and get an
electric shock.

 Before wiring or inspection, power must be switched OFF.

To confirm that, LED indication of the operation panel
must be checked. (It must be OFF.) Any person who is
involved in wiring or insp ection shall wait for at le ast 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 appli cable standards). A
neutral-point earthed (grounded) power supply for 400V
class inverter in compliance with EN standard must be used.

 Any person who is involved in wiring or inspection of this

equipment shall be fu lly competent to do the wo rk.

 The inverter must be installed before wiring. Otherwise

you may get an electric shock or be injured.

 Setting dial and key operations must be performed with

dry hands to prevent an electric shock. Otherwise you
may get an electric shock.
Do not subject the cables to scratches, excessive stress, heavy



loads or pinching. Otherwise you may get an electric shock.

 Do not change the cooling fan while power i s 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.
IPM motor is a synchronous motor with high-performance



magnets embedded in the rotor. Motor terminals hold 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. When the motor is driven by
the load in applications such as fan and blower, 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.

A-1

2. Fire Prevention

 Inverter (Filterpack) 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 can cause a fire.

 If the inverter has become faulty, the inverter power must

be switched OFF. A continuous flow of large current could
cause a fire.



When using a brake resistor, a sequence that will turn OFF
power when a fault signal is output must be configured.
Otherwise the brake resistor may overheat due to damage
of the brake transistor and possibly 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 produ ct is used without any
inspection, a burst, breakage, or a fire may occur.

3.Injury Prevention

 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.

 Polarity 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 (Filte rpack) since the inverte r (Filterpack)
will be extremely hot. Doi ng so can cause burns.

4. Additional Instructions

Also the following points must be noted to prevent an
accidental failure, injury, electric shock, etc.

(1) Transportation and Mounting

 The product must be transported in correct method that

corresponds to the weight. Failure to do so may lead to
injuries.

 Do not stack the boxes containing inverters higher than

the number recommended.

 The product must be installed to the position where

withstands the weight of the product according to the
information in the Instruction Manual.

 Do not install or operate the inverter (Filterpack) if i t is

damaged or has missing parts.

 When carrying the inverter, do not hold it by the front

cover or setting dial; it may fall off or fail.

 Do not stand or rest heavy objects on the product.
 The inverter mounting orientation must be correct.


Foreign conductive objects must be prevented from
entering the inverter (Filterpack). That includes screws and
metal fragments or other flammable substance such as oil.

 Because the inverter (Filterpack) is a precision

instrument, do not dr op or subject it to impact.

 The inverter (Filterpack) must be used under the following

environment conditions: Otherwise the inverter
(Filterpack) may be damaged.

1 Temperature applicable for a short time, e.g. in transit.
2 When installing the Filterpack of 11K or 15K on the rear

panel of the inverter, do not install on moving objects or
places which vibrates (exceeding 1.96m/s

2

).

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

CAUTION

iodine, etc.) infiltrate into a Mitsubishi Electric product,
the product will be damaged. Halogen-based materials are
often included in fumigant, w hich is used to steriliz e or
disinfest wooden packag es. When packaging, prev ent
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.

(2) 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 connection orientation of the output cables U, V, W to

the motor affects the rotation direction of the motor.

 IPM motor terminals (U, V, W) hold high-voltage while the

IPM motor is running even after the power is turned OFF.
Before wiring, the IPM motor must be confirmed to be
stopped. Otherwise you may get an electric shock.

 Never connect an IPM motor to the commercial power

supply. Applying the commercial power supply to input
terminals (U, V, W) of an IPM motor will burn the IPM
motor. The IPM motor must be connected with the output
terminals (U, V, W) of the inverter.

(3) 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.

(4) Usage

 The IPM motor capacity must be same with the inverter

capacity. (The 0.75K inverter can be used with a one-rank
lower motor.)

 Do not use multiple IPM motors with one inverter.
 Any person must stay away from the equipment when the

retry function is set as it will restart suddenly after trip.

Since pressing 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 alarm with
the start signal ON restarts the motor suddenly.

 Do not use an IPM motor in an application where a motor

is driven by its load and runs at a speed higher than the
maximum motor speed.
A dedicated IPM motor must be used under IPM motor



control. Do not use a synchronous motor, induction motor,
or synchronous induction motor under IPM motor control.

 The inverter must be used for three-phase induction

motors or the dedicated IPM 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.

 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 an EMC 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/damag e 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 the initial value.

 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. Otherwise the product may be
damaged.

 Do not connect an IPM motor under the general-purpose

motor control settings (initial settings). Do not use a
general-purpose motor under the IPM motor control
setting. Doing so will cause a failure.

 In the system with an IPM motor, the inverter power m ust

be turned ON before closing the contacts of the contactor
at the output side.

(5) 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
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 any protective function is activated, appropriate

corrective action must be taken, and the inverter must be
reset before resuming operation.

(6) 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.

(7) Disposal

 The inverter must be treated as industrial waste.

Reactors (option) must be used when
power harmonics measures are taken,
the power factor is to be improved or the
inverter is installed near a large power
supply system (500kVA or more). The

The breaker must be selected carefully
since an in-rush current flows in the
inverter at power on.

Install a noise filter (ferrite core)
to reduce the electromagnetic
noise generated from the
inverter. Effective in the range
from about 1MHz to 10MHz.
When more wires are passed
through, a more effective result
can be obtained. A wire should
be wound four turns or more.

* Not necessary if Filterpack (FR-BFP2) is used.

Earth (Ground)

To prevent an electric shock, always earth (ground)

The life of the inverter is influenced by surrounding ai r temperature. Use the product within the permissible surro unding
air temperature. This mu st be noted especiall y when the inverter is in stalled in an enclosure.

the Instruction Manual (Applied) .)

 Wrong wiring might lead to damage of the inverter. The control signal lines must be kept fully away from the main

circuit to protect them from noise. (Refer to page 10.)

 Do not install a power factor correction capacitor, surge suppressor or capacitor type filter on the inverter output

side. This will cause the inver ter to trip or the capacitor and surge s uppressor to be damaged. If an y of the above
devices are connected, immediately remove them.

 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. In this case, install the FR-BIF optional EMC filter
(capacitor) (for use in the input side only) or FR-BSF01 or FR-BLF EMC filter (ferrite core) to minimize interference.

( Refer to Chapter 3 of the Instruction Manual (Applied).)

 Refer to the Instruction Manual of each option and peripheral devices for details of peripheral devices.
 An IPM motor cannot be driven by the commercial power supply.
 An IPM 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.

 Connect the Filterpack terminals P and P1 to the inverter terminals of P/+ and P1, respectively. Improper connections

may damage the inverter.

2.3.5 Cables and wiring length

(1) Applicable cable size

Select the recommended cable size to ensure that a voltage drop will be 2% at maximum.
If the wiring distance is long between the inverter and motor, a main circuit cable voltage drop will cause the motor torque to
decrease especially at the output of a low frequency.
The following table indicates a selection example for the wiring length of 20m.

Use one dedicated IPM motor for one inverter. Multiple IPM motors cannot be connected to an inverter.

NOTE

 Especially for long-distance wiring, the inverter may be affected by a charging current caused by the stray

capacitances of the wiring, leading to a malfunction of the overcurrent protective function, fast-response current limit
function, or stall prevention function or a malfunction or fault of the equipment connected on the inverter output side.
If malfunction of fast-response current limit function occurs, disable this function.
If malfunction of stall prevention function occurs, increase the stall level.

( Refer to Pr. 22 Stall prevention operation level and Pr. 156 Stall prevention operation selection in Chapter 4 of the Instruction

Manual (Applied).)

 When using the automatic restart after instantaneous power failure function for a general-purpose motor with the

(3) Control circuit common terminals (SD, 5, SE)

• Terminals SD, SE and 5 are common terminals for I/O signals. (All common terminals are isolated from each other.) Do not

earth them. Avoid connecting the terminals SD and 5 and the terminals SE and 5.

• Terminal SD is a common terminal for the contact input terminals (STF, STR, RH, RM, AU) and the pulse train output

terminal (FM). The open collector circuit is isolated from the internal control circuit by photocoupler.

• Terminal 5 is a common terminal for the frequency setting signals (terminals 2 or 4). It should be protected from external

noise using a shielded or twisted cable.

• Terminal SE is a common terminal for the open collector output terminal (RUN). The contact input circuit is isolated from the

internal control circuit by photocoupler.

Wiring

(4) Wiring instructions

• It is recommended to use the cables of 0.3mm2 to 0.75mm2 gauge for connection to the control circuit terminals.

• The maximum wiring length should be 30m (200m for terminal FM).

• Do not short across terminals PC and SD. Inverter may be damaged.

• When using contact inputs, use two or more parallel micro-signal contacts or

twin contacts to prevent contact faults since the control circuit input signals are

micro-currents.

• To suppress EMI, use shielded or twisted cables for the control circuit

terminals and run them away from the main and power circuits (including the

200V relay sequence circuit). For the cables connected to the control circuit terminals, connect their shields to the common

terminal of the connected control circuit terminal. When connecting an external power supply to the terminal PC, however,

connect the shield of the power supply cable to the negative side of the external power supply. Do not directly earth

(ground) the shield to the enclosure, etc.

• Always apply a voltage to the fault output terminals (A, B, C) via a relay coil, lamp, etc.

• When using an external power supply for transistor output, note the following points to prevent a malfunction caused by

undesirable current.

Do not connect any terminal SD on the inverter and the 0V terminal of the external power supply (when the sink logic is

selected).

Do not connect terminal PC on the inverter and the +24V terminal of the external power supply (when the source logic is

selected).

Do not install an external power source in parallel with the internal 24VDC power source (connected to terminals PC and

SD) to use them together.

Refer to Chapter 2 of the Instruction Manual (Applied) for the detail.

PRECAUTIONS FOR USE OF THE INVERTER

3 PRECAUTIONS FOR USE OF THE INVERTER

The FR-F700PJ series is a highly reliable product, but using incorrect peripheral circuits or incorrect operation/handling

methods may shorten the product life or damage the product.
Before starting operation, always recheck the following items.

(1) Use crimp terminals with insulation sleeve to wire the power supply and motor.

(2) Application of power to the output terminals (U, V, W) of the inverter will damage the inverter. Never perform

such wiring.

(3) After wiring, wire offcuts must not be left in the inverter (Filterpack).

Wire offcuts can cause an alarm, failure or malfunction. Always keep the inverter (Filterpack) clean.
When drilling mounting holes in an enclosure etc., take care not to allow chips and other foreign matter to enter the
inverter (Filterpack).

(4) Use cables of the appropriate size to make a voltage drop of 2% or less.

If the wiring distance is long between the inverter and motor, a main circuit cable voltage drop will cause the motor torque
to decrease especially at the output of a low frequency. Refer to page 22 for the recommended wire sizes.

(5) The total wiring length should be within the prescribed length.

Especially for long distance wiring, the fast-response current limit function may decrease, or the equipment connected to
the output side may malfunction. This is caused by a charging current due to the stray capacity of the wiring. Therefore,
note the overall wiring length. (Refer to page 24.)

(6) 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. For an inverter without Filterpack, install the FR-BIF
optional capacitor type filter (for use in the input side only), FR-BSF01 or FR-BLF line noise filter to minimize
interference.

(7) Electrical corrosion of the bearing

When a motor is driven by the inverter, axial voltage is generated on the motor shaft, which may cause electrical
corrosion of the bearing in rare cases depending on the wiring, load, operating conditions of the motor or specific inverter
settings (high carrier frequency, use of a capacitive filter).
The following shows examples of countermeasures for the inverter.

 Decrease the carrier frequency.
 Remove the capacitive filter.
 Provide a common mode choke on the output side of the inverter. (This is effective regardless of the use of the

capacitive filter.)

 Mitsubishi Electric capacitive filter: FR-BIF, SF[], FR-E5NF-[], FR-S5NFSA[], FR-BFP2-[]

 Recommended common mode choke: FT-3KM F series FINEMETR

FINEMET is a registered trademark of Hitachi Metals, Ltd.

(8) Do not install a power factor correction capacitor, surge suppressor or capacitor type filter on the inverter

output side.

This will cause the inverter to trip or the capacitor and surge suppressor to be damaged. If any of the above devices are
connected, immediately remove them.

(9) For some short time after the power is switched OFF, a high voltage remains in the smoothing capacitor.

When accessing the inverter for inspection, wait for at least 10 minutes after the power supply has been switched OFF,
and then make sure that the voltage across the main circuit terminals P/+ and N/- of the inverter is no more than 30VDC
using a tester, etc.

(10) A short circuit or earth (ground) fault on the inverter output side may damage the inverter modules.

 Fully check the insulation resistance of the circuit prior to inverter operation since repeated short circuits may damage

the inverter modules. These short circuits may be caused by peripheral circuit inadequacy, an earth (ground) fault
caused by wiring inadequacy, or reduced motor insulation resistance.

 Fully check the to-earth (ground) insulation and phase to phase insulation of the inverter output side before power-on.

Especially for an old motor or use in a hostile atmosphere, securely check the motor insulation resistance etc.

PRECAUTIONS FOR USE OF THE INVERTER

3

(11) Do not use the inverter input side magnetic contactor to start/stop the inverter.

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 MC must be avoided. Turn ON/OFF the inverter start controlling terminals (STF,
STR) to run/stop the inverter.

(12) Across terminals P/+ and PR, connect only an external brake resistor.

Do not connect a mechanical brake.

(13) Do not apply a voltage higher than the permissible voltage to the inverter I/O signal circuits.

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 terminals 10 and 5.

(14) To use the commercial power supply, be sure to provide

electrical and mechanical interlocks between the electronic
bypass contactors MC1 and MC2.

When using a switching circuit as shown right, chattering due to
misconfigured sequence or arc generated at switching may
allow undesirable current to flow in and damage the inverter.
Miswiring may also damage the inverter.

(15) If the machine must not be restarted when power is restored after a power failure, provide a magnetic contactor

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.

(16) Inverter input side magnetic contactor (MC)

On the inverter input side, connect a MC for the following purposes. (Refer to page 7 for selection.)

1)To release the inverter from the power supply when a fault occurs or when the drive is not functioning (e.g. emergency
stop operation). For example, MC avoids 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.

2)To prevent any accident due to an automatic restart at restoration of power after an inverter stop made by a power
failure

3)To separate the inverter from the power supply to ensure safe maintenance and inspection work.

If using an MC for emergency stop during operation, select an MC regarding the inverter input side current as JEM1038­AC-3 class rated current.

(17) Handling of inverter output side magnetic contactor

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. If an MC is provided to switch to the commercial power supply or for similar purposes under general-purpose
motor control, switch the MC after the inverter and motor have stopped.

(18) Countermeasures against inverter-generated EMI

If electromagnetic noise generated from the inverter causes frequency setting signal to fluctuate and motor rotation
speed to be unstable when changing motor speed with analog signal, 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 shield cables as signal cables.
 Install a ferrite core on the signal cable (Example: ZCAT3035-1330 TDK).

(19) Instructions for overload operation

When performing operation of frequent start/stop of 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. Decreasing current may increase the life. However, decreasing current will result in insufficient torque and
the inverter may not start. A counter action for this is to raise the permissible current level by increasing the inverter
capacity (up to 2 ranks) when using a general-purpose motor, and by increasing the inverter and IPM motor capacities
when using an IPM motor.

4 FAILSAFE OF THE SYSTEM WHICH USES THE INVERTER

When a fault occurs, the inverter trips to output a fault signal. However, a fault output signal may not be output at an inverter

fault occurrence when the detection circuit or output circuit fails, etc. Although Mitsubishi Electric assures best quality

products, provide an interlock which uses inverter status output signals to prevent accidents such as damage to machine

when the inverter fails for some reason and at the same time consider the system configuration where failsafe from outside

the inverter, without using the inverter, is enabled even if the inverter fails.

(1) Interlock method which uses the inverter status output signals

By combining the inverter status output signals to provide an interlock as shown below, an inverter alarm can be

detected.

(2) 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, when the inverter CPU fails, even if the interlock is provided using the inverter

fault signal, start signal and RUN signal, there is a case where a fault signal is not output and RUN signal is kept output

even if an inverter fault occurs.

Provide a speed detector to detect the motor speed and current detector to detect the motor current and consider the

backup system such as checking up as below according to the level of importance of the system.

1)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 motor

current runs as the motor is running for the period until the motor stops since the inverter starts decelerating even if the

start signal turns OFF. For the logic check, configure a sequence considering the inverter deceleration time. In addition, it

is recommended to check the three-phase current when using the current detector.

2)Command speed and actual operation check

Check if there is no gap between the actual speed and commanded speed by comparing the inverter speed command

and detected speed of the speed detector.

5 DRIVING THE IPM MOTOR

Highly efficient motor control and highly accurate motor speed control can be performed by using the inverter with an IPM motor.

The motor speed is detected by the output voltage and current of the inverter. It does not require a speed detector such as an

encoder. The inverter drives the IPM motor with the least required current when a load is applied in order to achieve the

highest motor efficiency.

Refer to Chapter 4 of the Instructio n Manual (Applied) for the details of the IPM motor control.

POINT

The following conditions must be met to perform IPM motor control.

 For the motor model, dedicated IPM motor (MM-EF (1800r/min specification)) must be used.
 The motor capacity must be equivalent to the inverter capacity.
 Single-motor operation (one motor run by one inverter) must be performed.
 The overall wiring length with the motor must be 100m or less (50m or less for the 400V class 0.4K).

5.1 Setting procedure of IPM motor control

This inverter is set for a general-purpose motor in the initial setting. Follow the following procedure to change the setting for

the IPM motor control.

Perform IPM parameter initialization by selecting the parameter setting mode (IPM) on the operation panel.* (Refer to page 24.)

Set "1" or "12" in " " (IPM parameter initialization)
to select IPM motor control. Refer to pa ge 24 for the setting
method.
Setting value "1": MM-EF
Setting value "12": MM-EFS

Set parameters such as the acceleration/deceleration time and multi-speed setting.

Set parameters such as the acceleration /deceleration time
and multi-speed setting as required.

Set the operation command. ( Refer to Chap ter 4 of the Instruction Manual (Applied).)

Tes t run

 Initialization is performed by setting Pr.998 IPM parameter initialization or by choosing the mode on the operation panel.

To change to the IPM motor control, perform IPM parameter initialization at first. If parameter initialization is performed after setting other parameters, some

of those parameters will be initialized too. ( Refer to Chapter 4 of the Instruction Manual (Applied) for the parameters that are initialized.)

REMARKS

 IPM motor control can also be selected with Pr. 80 Motor capacity and Pr. 998 IPM parameter initialization . ( Refer to

Chapter 4 of the Instruction Manual (Applied).)

 To check the control method (general-purpose motor control/IPM motor control), simply press the setting dial while the monitor

screen is displayed. (

Refer to Chapter 4 of the Instruction Manual (Applied).)

NOTE

 The selectable carrier frequencies under IPM motor control are 2.5kHz, 5kHz, 7.5kHz, 10kHz and 12.5kHz.
 Constant-speed operation cannot be performed in the low-speed range of less than 150r/min (for the 1500r/min

specification MM-EFS) or 180r/min (for the 1800r/min specification MM-EFS). Generally, speed control can be
performed in the range that satisfies the ratio, 1:10.

 During IPM motor control, the RUN signal is output about 100ms after turning ON the start command (STF, STR). The

delay is due to the magnetic pole detection.

 The following operations and controls are disabled during IPM motor control: stop by power failure, Optimum

excitation control, and speed smoothing control.

 The option surge voltage suppression filter (FR-ASF-H/FR-BMF-H) cannot be used under IPM motor control, so do

not connect them.

 When parameter copy is performed from a FR-F700PJ series inverter, which is set to use MM-EFS under IPM motor

control, check that IPM motor control is selected on the operation panel after the copy. When parameters are copied
to a FR-F700PJ series inverter, which is not compatible with MM-EFS, General-purpose magnetic flux vector control
is selected instead of IPM moto r control.

Select the start command and speed command.

REMARKS

To change the value to 120Hz or more, the maximum frequency must be set to 120Hz or more.

Use calibration parameter C2 to set frequency at 0V and

calibration parameter C0 to adjust the meter.

selection = "0". The initial value is "1 (0 t o 5V input)".

(

Refer to Chapter 4 of the Instruction Ma nual (Applied).)

As other adjustment methods of frequency setting voltage gain, there are methods to adjust with a voltage applied across
terminals 2 and 5 or a method to adjust at any point without a voltage applied. ( Refer to Chapter 4 of the Instruction Manual
(Applied) for the setting method of calibration parameter C4.)

7 ENERGY SAVING OPERATION FOR FANS AND

PUMPS

Set the following functions to perform energy saving operation for fans and pumps.

(1) Load pattern selection (Pr. 14)

Select the optimum output characteristic (V/F characteristic) that is suitable for the

application and load characteristics.

 Set Pr.14 Load pattern selection = "1 (for variable-torque load)."

 When the output frequency is equal to or less than the base frequency, the output voltage

changes by its square in proportion to the output frequency.

Use this setting to drive a load whose load torque changes in proportion to the square of

the speed, such as a fan and a pump.

NOTE

 Load pattern selection is available only under V/F control. Load pattern selection is not available under IPM motor

control and General-purpose magnetic flux vector control. (

(2) Optimum excitation control (Pr. 60)

Without a detailed parameter setting, the inverter automatically performs energy saving operation.

This operation is optimum for fan and pump applications.

 Set Pr.60 Energy saving control selection = "9 (optimum excitation control mode)."

 The Optimum excitation control mode is a control system which controls excitation current to improve the motor efficiency

to the maximum and determines output voltage as an energy saving method.

REMARKS

 When the motor capacity is too small as compared to the inv erter capacity or two or more motors are conne cted to one inverter,

the energy saving effect is not expected.

Refer to Chapter 4 of the Instruction Manual (Applied).)

NOTE

 When the Optimum excitation control mode is selected, deceleration time may be longer than the setting value. Since

 Optimum excitation control is available only under V/F control. Optimum excitation control is not available under IPM

 Optimum excitation control will not be performed during an automatic restart after instantaneous power failure.

 Since output voltage is controlled by Optimum excitation control, output current may slightly increase.

overvoltage alarm tends to occur as compared to the constant-torque load characteristics, set a longer deceleration

When a fault occurs in the inverter, the inverter output is shut off and the PU display automatically changes to one of the
following fault or alarm indications.
If the fault does not correspond to any of the following faults or if you have any other problem, please contact your sales
representative.



Retention of fault output signal

 Fault or alarm indication...........When a fault or alarm occurs, the operation panel display automatically switches to the fault

 Resetting method.....................When a fault occurs, the inverter output is kept stopped. Unless reset, therefore, the inverter

 When any fault occurs, take the appropriate corrective action, then reset the inverter, and resume operation.

Not doing so may lead to the inverter fault and damage.

Inverter fault or alarm indications are roughly categorized as below.
(1) Error message

A message regarding operational fault and setting fault by the operation panel and parameter unit (FR-PU04 /FR-PU07)
is displayed. The inverter output is not shut off.

(2) Warning

The inverter output is not shut off even when a warning is displayed. However, failure to take appropriate measures will lead to
a fault.

(3) Alarm

The inverter output is not shut off. You can also output an alarm signal by making parameter setting.

(4) Fault

When a fault occurs, the inverter output is shut off and a fault signal is output.

REMARKS

 For the details of fault displays and other malfunctions, also refer to the Instruction Manual ( Applied).
 Past eight faults can be displayed using the setting dial. (Refer to page 4 for the operation.)

cannot restart. (Refer to page 39.)

The inverter can be reset by performing any of the following operations. Note that the internal thermal integrated value of the
electronic thermal relay function and the number of retries are cleared (erased) by resetting the inverter.
Inverter recovers about 1s after the reset is released.

Operation 1 ........ Using the operation panel, press to reset the inverter.

(This may only be performed when a fault occurs. (Refer to page 40 for
fault.))

Operation 2 ........ Switch power OFF once. After the indicator of the operation panel

turns OFF, switch it ON again.

Operation 3 ........ Turn ON the reset signal (RES) for more than 0.1s. (If the RES signal

is kept ON, "Err." appears (blinks) to indicate that the inverter is in a
reset status.)

NOTE

 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.

PRECAUTIONS FOR MAINTENANCE AND INSPECTION

The inverter is a static unit mainly consisting of semiconductor devices. Daily inspection must be performed to prevent any
fault from occurring due to the adverse effects of the operating environment, such as temperature, humidity, dust, dirt and
vibration, changes in the parts with time, service life, and other factors.

REMARKS

 For maintenance/inspection and parts life, also refer to the Instruction Manual (Applied).

Precautions for maintenance and inspection

For some short time after the power is switched OFF, a high voltage remains in the smoothing capacitor. When accessing the
inverter for inspection, wait for at least 10 minutes after the power supply has been switched OFF, and then make sure that
the voltage across the main circuit terminals P/+ and N/- of the inverter is not more than 30VDC using a tester, etc.

 The applicable motor capacity indicated is the maximum capacity applicable for use of the Mitsubishi Electric 4-pole standard motor. To use a dedicated IPM

motor, refer to page 47, 48.

 The rated output capacity assumes the following output voltages: 220V for the three-phase 200V and 440V for the three-phase 400V class.
 The % value of the overload current rating indicated is the ratio of the overload current to the inverter's rated output current. For repeated duty, allow time for

the inverter and motor to return to or below the temperatures under 100% load.

 The maximum output voltage does not exceed the power supply voltage. The maximum output voltage can be changed within the setting range. However,

the pulse voltage value of the inverter output side voltage remains unchanged at about that of the power supply.

 The power supply capacity varies with the value of the power supply side inverter impedance (including those of the input reactor and cables).

 The regenerative braking torque indicates the average short-time torque (which varies by the motor loss) that is generated when a motor decelerates in the

shortest time by itself from the rated speed. It is not the continuous regenerative torque. When a motor decelerates from a speed higher than the rated
speed, the average deceleration torque decreases. When the regenerative power is large, use an option brake unit.
