This section is specifically about safety matters
Do not attempt to install, operate, maintain or inspect th e
inverter until you have read through the Inst ruction 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".
Incorrect handling m ay cause
hazardous conditions, resulting in
death or severe injur y.
Incorrect handling m ay cause
hazardous conditions, resulting in
medium or slight injury, or may cause
only material damage.
The level may even lead to a se rious
consequence according to conditions. Both instruction
levels must be followed because these are important to
personal safety.
1. Electric Shock Prevention
While power is ON or when the inverter is running, do not
open the front cover. Otherwise you may g et an electric
shock.
Do not run the inverter with the front cover or wiring cover
removed. Otherwis e you may access the exposed highvoltage terminals or t he charging part of the ci rcuitry 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 inspect ion, power must be sw itched OFF.
To confirm that, LED indication of the operation panel
must be checked. (It must be OFF.) Any person who is
involved in wiring o r inspection shall wait for at least 10
minutes after the power supply has been switched OFF
and check that there are n o residual voltage using a tester
or the like. The capacitor is charged with high voltage for
some time after power OFF, and it is dangerous.
This inverter must be earthed (grounded). Earthing
(grounding) must conform to the requirements of national
and local safety regulations and electrical code (NEC section
250, IEC 536 class 1 and other applicab le 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 f ully competent to do the work.
The inverter must be installed before wiring. Otherwise
you may get an elect ric shock or be injured.
Setting dial and key operations must be performed with
dry hands to prevent an electric shock.
Do not subject the c ables to scratches, excess ive stress,
heavy loads or pinchi ng. Otherwise you may get an
electric shock.
Do not change the cooling f an 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 th e main circuit capacitor ca pacity, the
DC voltage is applied to the motor for 1s at powering OFF.
Never touch the motor terminal, etc. right after powerin g
OFF to prevent an e lectric shock.
2. Fire Prevention
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
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 res istor, a sequence that will turn OFF
power when a fault signal is output must be configured.
Otherwise the brak e resistor may overheat due to damage
of the brake transi stor and possibly cause a fire.
Do not connect a resistor directly to the DC terminals P/+
and N/-. Doing so could cause a fire.
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 co nnected to the correct terminals.
Otherwise burst, dam age, etc. may occur.
Polarity must be cor rect. Otherwise burst, damage, etc.
may occur.
While power is ON or for some time after power-OFF, do
not touch the inver ter as they will be extremely hot. Doing
so can cause burns.
4. Additional Instructions
Also the following points must be noted to prevent an
accidental failure, injury, electric shoc k, 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 c ontaining inverters higher th an
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 if it is damaged or
has parts missing.
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. That includes screws and metal
fragments or other flammable substance such as oil.

(5) Emergency stop
Do not install a power factor correction capacitor or sur ge
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.
(3) Trial run
Be fore starting operation, each parameter must be
confirmed and adjusted. A failu re to do so may cause
some machines to make unexpected motions.
(4) Usage
An y person must stay away from the equipment wh en the
retry function is set as it will restart suddenly after trip.
S ince pressing key may not stop output dependin g
on the function setting status, separate circ uit and switch
that make an emerg ency stop (power OFF, mechanical
brake operation for emer gency stop, etc.) must be
provided.
OFF status of the start signal must be confirmed before
resetting the inv erter fault. Resettin g inverter alarm wit h
the start signal ON restarts the motor suddenly.
The inverter mu st be used for thre e-phase induction motors.
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 in structed 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 bo th an external thermal and P TC
thermistor for overh eat 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.
T he effect of electrom agnetic interference m ust be
reduced by using a noise filter or by other means.
Otherwise nearby e lectronic equipment may b e affected.
Appr opriate measures must be taken to suppress
harmonics. Otherwise power supply harmonics from the
inverter may heat/dam age the power factor corr ection
capacitor and generator.
W hen driving a 400V class motor by the i nverter, 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.
W hen parameter clear or a ll parameter clear is pe rformed,
the required paramete rs must be set agai n before starting
operations becau se all parameters return t o 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 t he inverter’s brake function, a
holding device must be installed to ensure safety.
Be fore running an inverter which had been stored for a long
period, inspection and test operation must be performed.
F or prevention of damage due t o static electricity, nearby
metal must be touched before touching this product to
eliminate static electricity from your body.
A s afety backup such as an em ergency brake must be
provided to prevent hazardous condition to the machine
and equipment in ca se of inverter failure.
W hen 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 cau se
of the trip must be identified and removed before turning
ON the power of the breaker.
W hen any protective function is activated, ap propriate
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
T he inverter must be trea ted as industrial waste.

Check the inverter model of the inverter you purchased. Appropriate peripheral devices must be selected according to the capacity.
Refer to the following list and prepare appropriate peripheral devices.
Select an MCCB according to the power supply capacity.
Install one MCCB per inverter.
For the use in the United States or Canada, select a UL and cUL certified fuse with Class T fuse equivalent cut-off
speed or faster with the appropriate rating for branch circuit protection. Alternatively, select a UL489 molded case circuit breaker (MCCB). (Refer to page 52)
Magnetic contactor is selected based on the AC-1 class. The electrical durability of magnetic contactor is 500,000 times. When the magnetic contactor is
used for emergency stop during motor driving, the electrical durability is 25 times.
When using the MC for emergency stop during motor driving or using on the motor side during commercial-power supply operation, select the MC with c lass
AC-3 rated current for the motor rated current.
The power factor may be slightly lower.
NOTE
When the inver ter capacity is larger than t he motor capacity, select an MCCB and a m agnetic contactor according t o
the inverter model and cable and reactor according to the motor output.
When the breaker on the inverter input side trips, check for the wiring fault (short circuit), damage to internal parts of
the inverter, etc. Identify the ca use of the trip, then rem ove the cause and power O N the breaker.

Use a blade terminal and a wire with a sheath stripped off for the control circuit wiring. 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 about the size below. If the length of the sheath peeled is too long, a short circuit may occur
among neighboring wires. If the length is too short, wires might come off.
Wire the stripped wire after twisting it to prevent it from becoming loose. In addition, do not solder it.

(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, RL, RES) and frequency output signal
(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 (terminal 2 or 4). It should be protected from external noise
using a shielded or twisted wire.
Terminal SE is a common terminal for the open collector output terminal (RUN, FU). The contact input circuit is isolated from
the internal control circuit by photocoupler.
(4) Wiring instructions
1) It is recommended to use the wires of 0.3mm2 to 0.75mm2 gauge for connection to the control circuit terminals.
2) The maximum wiring length should be 30m ( 200m for terminal FM).
3) Do not short terminals PC and SD. Inverter may be damaged.
4) Use two or more parallel micro-signal contacts or twin contacts to prevent
contact faults wh en using contact inputs since the control circui t input signals
are micro-currents.
5) Use shielded or twisted wires for connection to the control circuit terminals and
run them away from the main and power circuits (including the 200V relay
sequence circuit).
6) Do not apply a voltage to the contact input terminals (e.g. STF) of the control
circuit.
7) Always apply a voltage to the fault output terminals (A, B, C) via a relay coil, lamp, etc.

Refer to the table below for the type number of each capacity of thermal relay and the diagram below for t he connection.
(Always install a thermal relay when using a brake resistor whose capacity is 11K or higher.)
When the power supply is 400V class, install a step-down transformer.
The brake resistor connected should only be the dedicated brake resistor.
Perform wiri ng and operation accor ding to the Instruction M anual of each option un it.
Brake resistor can not be used with the brake unit, high power factor converter, power supply regeneration converter,

PRECAUTIONS FORUSE OF THE INVERTER
3PRECAUTIONS FOR USE OF THE INVERTER
The FR-E700 s eries 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.
(1) Use crimping 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.
Wire offcuts can cause an alarm, failure or malfunction. Always keep the inverter clean.
When drilling mounting holes in an enclosure etc., take care not to allow chips and other foreign matter to enter the
inverter.
(4) Use cables of the size to make a voltage drop 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 13 for the recommende d wire sizes.
(5) The overall wiring length should be 500m or less.
Especially for long distance wiring, the fast-response current limit function may decrease or the equipment connected to
the secondary side may malfunction or become faulty under the influence of a charging current due to the stray capacity
of the wiring. Therefore, note the overall wiring length. (Refer to page 14)
(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. In this case, install options among the capacitor type
EMC filter FR-BIF (for use in the input side only), the ferrite core type EMC filter FR-BSF01/FR-BLF, filterpack, and EMC
filter to minimize the interference.
(7) Do not install a power factor correct ion capacitor, surge s uppressor or capacitor type filter on the in verter
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 re move them. (When using capacitor type filter (FR-BIF) for si ngle-phase power input model,
make sure of secure insulation of T-phase, and connect to the input side of the inverter.)
(8) 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 t han 30VDC
using a tester, etc. The capacitor is charged with high voltage fo r some time after power OFF and it is dangerous.
(9) If "EV" is displayed on the operation panel, turn off the 24V external power supply before wiring and inspection.
(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 caused by
peripheral circuit inadequ acy or an earth (ground) fault caused by wiring inad equacy or reduced motor insulation
resistance may damage the inverter modules.
Fully check the to-earth (ground) insulation and phase to phase insulation of the inverter o utput side be fore power-ON.
Especially for an old motor or use in hostile atmosphere, securely check the motor insulation resistance etc.
(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. ( Refer to the Instruction Manual (Applied))

(12) Across terminals P/+ and PR, connect only an external regenerative brake discharging resistor.
Do not connect a mechanical brake.
The brake resistor can not be connected to the 0.1KSC or 0.2KSC. Leave terminals P/+ and PR open.
Also, never short between these terminals.
(13) Do not apply a voltage higher th an the permis sible voltage to t he inverter I/O signal circuits.
Application of a voltage higher than the permissible voltage to the in verter 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) Provide electrical and mechanical interlocks for MC1 and
MC2 which are used for bypass operation.
When the wiring is incorrect and if there is a bypass operation
circuit as shown right, the inverter will be damaged when the
power supply is connected to the inverter U, V, W terminals,
due to arcs generated at the time of switch-over or chattering
caused by a sequence error.
(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 sid e 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 regen erative tran sistor is dama ged with short while connecting an optional brake resistor.
2)To prevent any accident due to an automa tic 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.
The inverter's input side MC is used for the above purpose, select class JE M1038-AC3 MC for the inv erter input side
current when making an emergency stop during normal operation.
(17) Handling of inv erter 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. When MC is provided for switching to the commercial power supply, for example, switch it ON/OFF after the
inverter and mo tor 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. Therefore, choose the inverter which has enough allowance for current (up to 2 rank larger in
capacity).
(20) Make sure that the specifications and rating match the system requirements.

FAILSAFE OF THE SYSTEM WHICH USES THE INVERTER
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 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 output signal, start signal and RUN signal output, there is a case where a fault output 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 impo rtance 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 op eration 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.

(Advanced magnetic flux vector control
magnetic flux vector control
Advanced magnetic flux vector control can be selected by setting the capacity, poles and type of the motor used in Pr.
80 and Pr. 81.
Advanced magnetic flux vector control, General-purpose magnetic flux vector control?
The low speed torque can be improved by providing voltage compensation to flow a motor current which meets the
load torque. Output frequency compensation (slip compensation) is made so that the motor actual speed
approximates a speed command value. Effective when load fluctuates drastically, etc.
General-purpose magnetic flux vector control is the same function as it is for the FR-E500 series. Select this control
when operation characteristics as similar as possible are required when replacing from the FR-E500 series. For other
cases, select Advanced magnetic flux vector control.

POINT
If the following conditions are not satisfied, select V/F con trol since malfu nction such as insufficient torq ue and
uneven rotation may occur.
The motor capacity should be equal to or one rank lower than the inverter capacity. (Note that the capacity
should be 0.1kW or higher.)
Motor to be used is any of Mitsubishi standard motor (SF-JR 0.2kW or more), high efficiency motor (SF-HR
0.2kW or more) or Mitsubishi constant-torque motor (SF-JRCA four-pole, SF-HRCA 0.2kW to 15kW). When
using a motor other than the above (other manufacturer's motor), perform offline auto tuning without fail.
Single-motor operation (one motor run by one inverter) should be performed.
The wiring length from inverter to motor should be within 30m. (Perform offline auto tuning in the state where
wiring work is performed when the wiring length exceeds 30m.)
Permissible wiring length between inv erter and motor differs according to the inverter capacity and setting va lue
of Pr. 72 PWM frequency selection (carrier frequency). Refer to page 14 for the permissible wiring length.

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 fa ult 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 does not trip.
(2) Warning
The inverter does not trip even when a warning is displayed. However, failure to take appropriate measures will lead to a fault.
(3) Alarm
The inverter does not trip. You can also output an alarm signal by making parameter setting.
(4) Fault
When a fault occurs, the inverter trips and a fault signal is output.
REMARKS
For the details of f ault displays and other ma lfunctions, also refer to the Instruction Manual (Applied).
Past eight faults can be displayed using the s etting dial. (Refer to page 3 for the operation.)

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/in spection 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.
If "EV" is displayed on the operation panel with FR-E7DS mounted, turn off the 24V external power supply before an
inspection.

The applicable motor capacity indicated is the maximum capacity applicable for use of the Mitsubishi 4-pole standard motor.
The rated output capacity assumes the following output voltages: 230V for three-phase 200V/single-phase 200V, and 440V for three-phase 400V.
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. In a single-phase 200V class inverter with the automatic restart after the
instantaneous power failure (Pr.57) and the power failure stop (Pr.261) functions are set valid, a voltage drop at the power supply and a large load may bring
down the bus voltage to the level recognized as a power failure, disabling the inverter to drive a load 100% or higher.
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 braking torque indicated is a short-duration average torque (which varies with motor loss) when the motor alone is decelerated from 60Hz in the shortest
time and is not a continuous regenerative torque. When the motor is decelerated from the frequency higher than the base frequency, the average
deceleration torque will reduce. Since the inverter does not contain a brake resistor, use the optional brake resistor when regenerative energy is large. A
brake unit (FR-BU2) may also be used. (Option brake resistor cannot be used for 0.1K and 0.2K.)
The power supply capacity varies with the value of the power supply side inverter impedance (including those of the input reactor and cables).
Setting 2kHz or more in Pr. 72 PWM frequency selection to perform low acoustic noise operation with the surrounding air temperature exceeding 40°C, the
rated output current is the value in parenthesis.
Connect DC power supply t o terminal P/+ and N/-. Connect the plus side of the power supply to terminal P/+ and minus side to terminal N/-.
Since the voltage between P/+ and N/- may increase due to the regeneration energy from the motor and exceeds 415V temporarily, select the DC power
supply which can withstand the voltage/energy during regeneration. If using the power supply which can not withstand voltage/energy during regeneration,
insert diodes in series for reverse current prevention.
Although the FR-E700 series has the built-in inrush current limit circuit, select the DC power supply considering the inrush current at powering ON as the
inrush current four times of the rated inverter flows at powering ON.
Since the power supply capacity depends on the output impedance of the power, select the power supply capacity which has enough allowance according
to the AC power supply system capacity.

When using the electronic thermal relay function as motor overload protection, set the rated motor current to Pr. 9
"Electronic thermal O/L relay".
This function detects the overload (overheat)
of the motor, stops the operation of the
inverter's output transistor, and stops the
output.
(The operation characteristic is shown on the
left.)
When using the Mitsubishi constant-torque
motor
1) Set "1" or any of "13" to "16", "50", "53", "54"
in
Pr. 71
. (This provides a 100% continuous
torque characteristic in the low -speed range.)
2) Set the rated current of the motor in Pr. 9.
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 output current. It is not the
percentage to the motor rated current.
When you set the electronic thermal relay
function dedicated to the Mitsubishi constanttorque motor, this characteristic curve applies
to operation at 6Hz or higher.
