important to personnel safety.
1. Electric Shock Prevention
WARNING
z While power is on or when the inverter is running, do not open the front cover. You
may get an electric shock.
z Do not run the inverter with the front cover or wiring cover removed. Otherwise,
you may access the exposed high-voltage terminals or the charging part of the
circuitry and get an electric shock. Also, the inverter's ability to withstand
earthquakes will deteriorate.
z Even if power is off, do not remove the front cover except for wiring or periodic
inspection. You may access the charged inverter circuits and get an electric shock.
z Before starting wiring or inspection, check to make sure that the 3-digit LED inverter
monitor is off, wait for at least 10 minutes after the power supply has been switched
off, and check to make sure that there are no residual voltage using a tester or the
like.
z 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 536 class 1 and other applicable standards)
z Any person who is involved in the wiring or inspection of this equipment should be
fully competent to do the work.
z Always install the inverter before wiring. Otherwise, you may get an electric shock
or be injured.
z Perform setting dial and key operations with dry hands to prevent an electric
shock.
z Do not subject the cables to scratches, excessive stress, heavy loads or pinching.
Otherwise, you may get an electric shock.
z Do not change the cooling fan while power is on. It is dangerous to change the
cooling fan while power is on.
z When you have removed the front cover, do not touch the connector above the 3digit monitor LED display. Otherwise, you get an electrick shock.
A-1
2. Fire Prevention
CAUTION
z Install the inverter and brake resistor on an incombustible wall without holes, etc.
Installing the inverter and brake resistor directly on or near a combustible surface could
lead to a fire.
z If the inverter has become faulty, switch off the inverter power. A continuous flow of
large current could cause a fire.
z When using a brake resistor, make up a sequence that will turn off power when an
alarm signal is output. Otherwise, the brake resistor may excessively overheat due
to damage of the brake transistor and such, causing a fire.
z Do not connect the resistor directly to the DC terminals P and N. This could cause a fire.
3. Injury Prevention
CAUTION
z Apply only the voltage specified in the instruction manual to each terminal to
prevent damage, etc.
z Always connect to the correct terminal to prevent damage, etc.
z Always make sure that polarity is correct to prevent damage, etc.
z While power is on or for some time after power-off, do not touch the inverter as it is
hot and you may get burnt.
4. Additional Instructions
Also note the following points to prevent an accidental failure, injury, electric shock,
etc.
(1) Transportation and installation
CAUTION
Environment
z When carrying products, use correct lifting gear to prevent injury.
z Do not stack the inverter boxes higher than the number recommended.
z Ensure that installation position and material can withstand the weight of the
inverter. Install according to the information in the instruction manual.
z Do not install or operate if the inverter is damaged or has parts missing.
z When carrying the inverter, do not hold it by the front cover or setting dial; it may
fall off or fail.
z Do not stand or rest heavy objects on the inverter.
z Check the inverter mounting orientation is correct.
z Prevent other conductive bodies as screws and metal fragments or other
flammable substance as oil from entering the inverter.
z As the inverter is a precision instrument, do not drop or subject it to impact.
z Use the inverter under the following environmental conditions: This could cause
the inverter damage.
Ambient
-10°C to +50°C (non-freezing)

A-2
(2) Wiring
CAUTION
z Do not fit capacitive equipment such as power factor correction capacitor,
capacitor type filter (option FR-BIF(-H)) or surge suppressor to the output of the
inverter.
z The connection orientation of the output cables U, V, W to the motor will affect the
direction of rotation of the motor.
(3) Trial run
CAUTION
z Check all parameters, and ensure that the machine will not be damaged by a
sudden start-up.
z When the load GD2 is small (at the motor GD or smaller) for 400V from 1.5K to 3.7K, the
output current may vary when the output frequency is in the 20Hz to 30Hz range.
If this is a problem, set the Pr.72 "PWM frequency selection" to 6kHz or higher.
(When setting the PWM to a higher frequency, check for noise or leakage current
problem and take countermeasures against it.)
(4) Operation
WARNING
z When you have chosen the retry function, stay away from the equipment as it will
restart suddenly after an alarm stop.
z Since the [STOP] key is valid only when functions are set (refer to page 59),
provide a circuit and switch separately to make an emergency stop (power off,
mechanical brake operation for emergency stop, etc).
z Make sure that the start signal is off before resetting the inverter alarm. A failure to
do so may restart the motor suddenly.
z The load used should be a three-phase induction motor only. Connection of any
other electrical equipment to the inverter output may damage the equipment.
z Do not modify the equipment.
z Do not perform parts removal which is not instructed in this manual. Doing so may
lead to fault or damage of the inverter.
A-3
CAUTION
z The electronic thermal relay function does not guarantee protection of the motor
from overheating.
z Do not use a magnetic contactor on the inverter input for frequent starting/stopping
of the inverter.
z Use a noise filter to reduce the effect of electromagnetic interference. Otherwise
nearby electronic equipment may be affected.
z Take measures to suppress harmonics. Otherwise power supply harmonics from
the inverter may heat/damage the power capacitor and generator.
z When a 400V class motor is inverter-driven, please use an insulation-enhanced
motor or measures taken to suppress surge voltages. Surge voltages attributable to
the wiring constants may occur at the motor terminals, deteriorating the insulation of
the motor.
z When parameter clear or all clear is performed, reset the required parameters
before starting operations. Each parameter returns to the factory setting.
z The inverter can be easily set for high-speed operation. Before changing its
setting, fully examine the performances of the motor and machine.
z In addition to the inverter's holding function, install a holding device to ensure safety.
z Before running an inverter which had been stored for a long period, always
perform inspection and test operation.
(5) Emergency stop
CAUTION
z Provide a safety backup such as an emergency brake which will prevent the
machine and equipment from hazardous conditions if the inverter fails.
z When the breaker on the inverter primary side trips, check for the wiring fault (short
circuit), damage to internal parts of the inverter, etc. Identify the cause of the trip,
then remove the cause and power on the breaker.
z When any protective function is activated, take the appropriate corrective action,
then reset the inverter, and resume operation.
(6) Maintenance, inspection and parts replacement
CAUTION
z Do not carry out a megger (insulation resistance) test on the control circuit of the
inverter.
(7) Disposing of the inverter
CAUTION
z Treat as industrial waste.
(8) General instructions
Many of the diagrams and drawings in this instruction manual (basic) show the inverter
without a cover, or partially open. Never operate the inverter in this manner. Always replace
the cover and follow this instruction manual (basic) when operating the inverter.

The life of the inverter is influenced by ambient
temperature. Check the ambient temperature.
Epecially when mounting the inverter inside an
enclosure, take cautions of the ambient temperature.
(Refer to page 85.)
Wrong wiring might lead to damage of the inverter.
The control signal wires must be kept fully away from the
main circuit to protect them from noise. (Refer to page 7.)
Devices connected to the output
Do not install a power factor correction capacitor, surge
suppressor or capacitor type filter on the output side of the
inverter.
When installing a moulded case circuit breaker on the
output side of the inverter, contact each manufacturer for
selection of the moulded case circuit breaker.
Earth (Ground)
To prevent an electric shock, always earth (ground) the
motor and inverter.
For reduction of induction noise from the power line of
the inverter, it is recommended to wire the earth
(ground) cable by returning it to the earth (ground)
terminal of the inverter.
(For details of noise reduction techniques, refer to the

Power-off and magnetic contactor (MC)
(1) Inverter input side magnetic contactor (MC)
On the inverter's input side, it is recommended to provide an MC for the following
purposes. (Refer to page 4 for selection)
1) To release the inverter from the power supply when the inverter protective function
is activated or the drive becomes faulty (e.g. emergency stop operation)
When cycle operation or heavy-duty operation is performed with an optional brake
resistor connected, overheat and burnout of the electrical-discharge resistor can be
prevented if a regenerative brake transistor is damaged due to insufficient heat
capacity of the electrical-discharge resistor and excess regenerative brake duty.
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 rest the inverter for an extended period of time
The control power supply for inverter is always running and consumes a little power.
When stopping the inverter for an extended period of time, powering off the inverter
will save power slightly.
4) 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 JEM1038AC3 for the inverter input side current when making an emergency stop during
normal operation.
REMARKS
The MC may be switched on/off to start/stop the inverter. However, since repeated inrush
currents at power on will shorten the life of the converter circuit (switching life is about 100,000
times), frequent starts and stops must be avoided. Turn on/off the inverter start controlling
terminals (STF, STR) to run/stop the inverter.
As shown on the right,

(2) Handling of output side magnetic contactor
In principle, do not provide a magnetic contactor between the inverter and motor and
switch it from off to on during operation. If it is switched on during inverter operation, a
large inrush current may flow, stopping the inverter due to overcurrent shut-off. When
an MC is provided for switching to the commercial power supply, for example, switch it
on/off after the inverter and motor have stopped.

Failsafe of the system which uses the inverter
3.4 Failsafe of the system which uses the inverter
When a fault occurs, the inverter trips to output an alarm. However, an alarm output
signal may not be output at an inverter alarm 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

Failsafe of the system which uses the inverter
(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,
even if the interlock is provided using the inverter alarm output signal, start signal
and RUN signal output, there is a case where an alarm output signal is not output
and RUN signal is kept output even if an inverter alarm 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.

Precautions for maintenance and inspection
(1) Cooling fan
The cooling fan is used to cool heat-generating parts such as the main circuit
semiconductors. The life of the cooling fan bearing is usually 10,000 to 35,000 hours.
Hence, the cooling fan must be replaced every 2 to 3 years if the inverter is run
continuously. When unusual noise and/or vibration is noticed during inspection, the
cooling fan must be replaced immediately.

MMF-06D24ES-FC4 BKO-CA1027H09
zRemoval
1) Remove the front cover and wiring cover.
2) Unplug the fan connectors.
The cooling fan is connected to
the cooling fan connector beside
the main circuit terminal block of
the inverter.
Unplug the connector and
separate the inverter from the
cooling fan.
3) Remove the cooling fan cover.
Disengage the fixing hooks
pointed by arrows to remove the
cooling fan cover.
4) Remove the cooling fan and
cooling fan cover.
The cooling fan is secured by the
fixing hooks.
Disengage the fixing hooks to
remove the cooling fan and
cooling fan cover.
AIR FLOW
zReinstallation
1) After confirming the orientation of
the fan, reinstall the fan so that the
arrow on the left of "AIR FLOW"
faces up.
CAUTION
Installing the fan in the opposite air
flow direction can cause the
inverter life to be shorter.
2) Reinstall the fan cover to the inverter.
Run the cable through the wiring groove to prevent it from being caught
between the chassis and cover.
3) Reconnect the cable to the connector. (Refer to "Removal" for the position of
the connector.)
4) Reinstall the wiring cover.
78
Precautions for maintenance and inspection
(2) Smoothing capacitors
A large-capacity aluminum electrolytic capacitor is used for smoothing in the main
circuit DC section, and an aluminum electrolytic capacitor is used for stabilizing the
control power in the control circuit. Their characteristics are deteriorated by the
adverse effects of ripple currents, etc. The replacement intervals greatly vary with the
ambient temperature and operating conditions. When the inverter is operated in airconditioned, normal environment conditions, replace the capacitors about every 10
years.
When a certain period of time has elapsed, the capacitors will deteriorate more rapidly.
Check the capacitors at least every year (less than six months if the life will be expired
soon).
The appearance criteria for inspection are as follows:
1) Case: Check the side and bottom faces for expansion
2) Sealing plate: Check for remarkable warp and extreme crack.
3) Check for external crack, discoloration, fluid leakage, etc. Judge that the capacitor
has reached its life when the measured capacitance of the capacitor reduced below
85% of the rating.
(3) Relays
ERRORS AND PROTECTIVE FUNCTIONS
To prevent a contact fault, etc., relays must be replaced according to the cumulative
number of switching times (switching life).

For repeated duty, allow time for the inverter and motor to return to or below the
temperatures under 100% load.
*4. The maximum output voltage does not exceed the power supply voltage. You can set the
maximum output voltage to any value below the power supply voltage. However, the
pulse voltage value of the inverter output side voltage remains unchanged at about 2
that of the power supply.
*5. The power supply capacity varies with the value of the power supply side inverter
impedance (including those of the input reactor and cables).

When undervoltage or instantaneous power failure occurs, no alarm output is provided
but the output is shut off. After power restoration, the inverter may be run as it is.
Depending on the running status (e.g. load magnitude), however, overcurrent,
regenerative overvoltage or other protection may be activated at power restoration. (in the
external operation mode)
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 an optional brake resistor when regenerative
energy is large. (Available for the FR-S520E-0.4K to 3.7K only.) A brake unit (BU) may
also be used.
Compatible with only the product having the built-in cooling fan.

Appendix 1 Instructions for compliance with the
European Directive
(The products conforming to the Low Voltage Directive carry the CE mark.)
(1) EMC Directive
1)Our view of transistorized inverters for the EMC Directive
A transistorized inverter is a component designed for installation in an enclosure and
for use with the other equipment to control the equipment/device. Therefore, we
understand that the EMC Directive does not apply directly to transistorized inverters.
For this reason, we do not place the CE mark on the transistorized inverters. (The
CE mark is placed on inverters in accordance with the Low Voltage Directive.) The
European power drive manufacturers' organization (CEMEP) also holds this point of
view.
2)Compliance
We understand that the transistorized inverters are not covered directly by the EMC
Directive. However, the EMC Directive applies to machines/equipment into which
transistorized inverters have been incorporated, and these machines and
equipment must carry the CE marks. Hence, we prepared the European Standardcompliant noise filters and the technical information "EMC Installation Guidelines"
(information number BCN-A21041-202) so that machines and equipment
incorporating transistorized inverters may conform to the EMC Directive more
easily.
3)Outline of installation method
Install an inverter using the following methods:
* Use the inverter with an European Standard-compliant noise filter.
* For wiring between the inverter and motor, use shielded cables or run them in a
metal piping and earth (ground) the cables on the inverter and motor sides with the
shortest possible distance.
* Insert a common mode filter and ferrite core into the power and control lines as
required.
Full information including the European Standard-compliant noise filter
specifications are written in the technical information "EMC Installation Guidelines"
(BCN-A21041-202). Please contact your sales representative.
89
(2) Low Voltage Directive
1) Our view of transistorized inverters for the Low Voltage Directive
Transistorized inverters are covered by the Low Voltage Directive (Standard to
conform to: EN50178).
2) Compliance
We have self-confirmed our inverters as products compliant to the Low Voltage
Directive and place the CE mark on the inverters.
3) Outline of instructions
* For the 400V class inverter, the rated input voltage range is three-phase 380V to
415V 50Hz/60Hz.
* Do not use an earth leakage circuit breaker as an electric shock protector without
connecting the equipment to the earth. Connect the equipment to the earth securely.
* Wire the earth terminal independently. (Do not connect two or more cables to one
terminal.)
* Use the cable sizes on page 11 under the following conditions.
·Ambient temperature: 40°C maximum
*
*
*
*
*
*
*
·Wire installation: On wall without ducts or conduits
If conditions are different from above, select appropriate wire according to
EN60204 ANNEX C TABLE 5.
Use the moulded case circuit breaker and magnetic contactor which conform to
the EN or IEC Standard.
Use the breaker of type B (breaker which can detect both AC and DC). If not,
provide double or enhanced insulation between the inverter and other equipment,
or put a transformer between the main power supply and inverter.
Use the inverter under the conditions of overvoltage category II and contamination
level 2 or higher specified in IEC664.
On the input and output of the inverter, use cables of the type and size set forth in
EN60204 Appendix C.
The operating capacity of the relay outputs (terminal symbols A, B, C) should be
30VDC, 0.3A.
Control circuit terminals on page 7 are safely isolated from the main circuit.

Appendix 2 Instructions for UL and cUL
(Standard to comply with: UL 508C, CSA C22.2 No.14)
1. Installation
The S500E is UL-listed as a product for use in an enclosure.
Design the enclosure so that the ambient temperature, humidity and ambience of
the inverter will satisfy the above specifications. (Refer to page 85)
Branch circuit protection
For installation in the United States, branch circuit protection must be provided in
accordance with the National Electrical Code and any applicable local codes.
For installation in Canada, branch circuit protection must be provided in accordance
with the Canada Electrical Code and any applicable provincial codes.
2. Wiring of the power supply and motor
For wiring the input (R, S, T) and output (U, V, W) terminals of the inverter, use the
UL-listed copper wires (rated at 75°C) and round crimping terminals. Crimp the
crimping terminals with the crimping tool recommended by the terminal maker.
3. Short circuit ratings
Suitable For Use in A Circuit Capable Of Delivering Not More Than 100kA rms
Symmetrical Amperes.
91
4. Motor overload protection
These inverters provide solid state motor overload protection.
Set Pr. 9 using the following instructions,
(Pr. 9 "electronic thermal O/L relay").
<Setting>
•Set the rated current [A] of the motor in Pr. 9.
•Setting "0" in Pr. 9 disables electronic thermal relay function (motor protective function). (The protective function of the inverter is activated.)
•When using a Mitsubishi constant-torque motor, first set "1" in Pr. 71 "applied motor".
(This provides a 100% continuous torque characteristic in the low-speed range.)
Then, set the rated current of the motor in Pr. 9 "electronic thermal O/L relay".
CAUTION
•When two or more motors are connected to the inverter, they cannot be protected by
the electronic thermal relay function. Install an external thermal relay to each motor.
•When a difference between the inverter and motor capacities is large and the setting
becomes less than half amount of the inverter rated current, 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.
