Maintenance, Inspection and Parts Replacement
It is recommended to make the following checks periodically:
● Check for loose screws in the terminal block. Retighten any loose screws.
● Check for dust accumulation on the inverter. Clean the heat sink and the
cooling fan of the inverter.
● Check for unusual noise generated from the inverter. Retighten installation
screw.
● Check for the operation condition. Keep the operation condition of
inverter as written in the manual.
General Instructions
Many of the diagrams and drawings in instruction manuals show the inverter
without a cover, or partially open. Never run the inverter in this status. Always
replace the cover and follow this Installation Guideline when operating the
inverter.
2.5 Disposal
Disposal of unusable or irreparable devices should always occur in accordance
with the applicable country-specific waste-disposal regulations (e.g. European
Waste Code 16 02 14).
3 Product description
3.1 FR-D700 inverter
A FR-D700 frequency inverter is a device that converts the fixed voltage and
frequency of the mains power supply into a variable voltage with a variable
frequency. It is installed between the mains supply and the motor and makes
continuously-variable speed adjustment possible.
The adjustable frequency AC drive generates the rotational energy of the
motor, which in turn generates the torque of the motor. It controls induction
motors for a variety of automation applications such as air conditioning, con-
veyer, washing machine, machine tools, lift machines, etc.
3.2 Operation Panel
E
CAUTION
● Apply only the voltage specified in the instruction manual to each ter-
minal. Otherwise, burst, damage, etc. may occur.
● Ensure that the cables are connected to the correct terminals. Other-
wise, burst, damage, etc. may occur.
● Always make sure that polarity is correct to prevent damage, etc. Oth-
erwise, burst, damage, etc. may occur.
● While power is on or for some time after power-off, do not touch the in-
verter as it is hot and you may get burnt.
E
CAUTION
● Transport the product using the correct method that corresponds to
the weight. Failure to observe this could lead to injuries.
● Do not stack the inverter boxes higher than the number recommend-
ed.
● Ensure that installation position and material can withstand the
weight of the inverter. Install according to the information in the in-
struction manual.
● Do not install or operate the inverter if it is damaged or has parts miss-
ing. This can result in breakdowns.
● 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.
● Check the inverter mounting orientation is correct.
● Prevent other conductive bodies such as screws and metal fragments
or other flammable substance such as oil from entering the inverter.
● As the inverter is a precision instrument, do not drop or subject it to im-
pact.
● Use the inverter under the environmental conditions listed in
chapter 6 . Otherwise, the inverter may be damaged
E
CAUTION
● Do not install assemblies or components (e. g. power factor correction
capacitors) on the inverter output side, which are not approved from
Mitsubishi.
● The direction of rotation of the motor corresponds to the direction of
rotation commands (STF/STR) only if the phase sequence (U, V, W) is
maintained.
E
CAUTION
Before starting operation, confirm and adjust the parameters. A failure to
do so may cause some machines to make unexpected motions.
P
DANGER
● When you have chosen the retry function, stay away from the equip-
ment as it will restart suddenly after an alarm stop.
● Since pressing key may not stop output depending on the func-
tion setting status, provide a circuit and switch separately to make an
emergency stop (power off, mechanical brake operation for emergen-
cy stop, etc).
● Make sure that the start signal is off before resetting the inverter
alarm. A failure to do so may restart the motor suddenly.
● The inverter can be started and stopped via the serial port communi-
cations link or the field bus. However, please note that depending on
the settings of the communications parameters it may not be possible
to stop the system via these connections if there is an error in the com-
munications system or the data line. In configurations like this it is
thus essential to install additional safety hardware that makes it pos-
sible to stop the system in an emergency (e.g. controller inhibit via
control signal, external motor contactor etc). Clear and unambiguous
warnings about this must be posted on site for the operating and serv-
ice staff.
● The load used should be a three-phase induction motor only. Connec-
tion of any other electrical equipment to the inverter output may dam-
age the inverter as well as 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 inverter.
E
CAUTION
● 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 de-
creases.
● Use a noise filter to reduce the effect of electromagnetic interference
and follow the accepted EMC procedures for proper installation of fre-
quency inverters. Otherwise nearby electronic equipment may be af-
fected.
● Take appropriate measures regarding harmonics. Otherwise this can
endanger compensation systems or overload generators.
● When a 400 V 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.
● When parameter clear or all clear is performed, set again the required
parameters before starting operations. Each parameter returns to the
initial value.
● The inverter can be easily set for high-speed operation. Before chang-
ing its setting, fully examine the performances of the motor and ma-
chine.
● The DC braking function of the frequency inverter is not designed to
continuously hold a load. Use an electro-mechanical holding brake on
the motor for this purpose.
● Before running an inverter which had been stored for a long period, al-
ways perform inspection and test operation.
● For prevention of damage due to static electricity, touch nearby metal
before touching this product to eliminate static electricity from your
body.
E
CAUTION
● Provide a safety backup such as an emergency brake which will pre-
vent the machine and equipment from hazardous conditions if the in-
verter fails.
● When the breaker on the inverter primary side trips, check for the wir-
ing 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.
● When the protective function is activated (i. e. the frequency inverter
switches off with an error message), take the corresponding corrective
action as described in the inverter manual, then reset the inverter, and
resume operation.
E
CAUTION
Do not carry out a megger (insulation resistance) test on the control cir-
cuit of the inverter. It will cause a failure.
NOTES
● The FR-D700 complies to the EMC Directive 2004/108/EC and the relevant
requirements of EN61800-3:2004 (Second environment/PDS category "C3".
The FR-D700 is therefore only suitable for use in an industrial environment
and not for private use. If you want to use FR-D700 inverter in first environ-
ment you will have to add an external RFI filter.
● The FR-D700 complies to the Low Voltage Directive 2006 and the relevant re-
quirements of EN61800-5-1:2007.
