1. Electric Shock Prevention
WARNING
• While power is ON or when the inverter is running, do not open
the front cover. Otherwise you may get an electric shock.
• Do not run the inverter with the front cover or wiring cover
• 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.
• 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 connected to the correct terminals.
Otherwise burst, damage, etc. may occur.
• Polarity must be correct. Otherwise burst, damage, etc. may
occur.

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 access the charged
inverter circuits and get an electric shock.
• Before wiring, inspection or switching EMC filter ON/OFF
connector, 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, inspection or
switching EMC filter ON/OFF connector shall wait for at least
10 minutes after the power supply has been switched OFF and
check that there are no residual voltage using a tester or the
like. The capacitor is charged with high voltage for some time
after power OFF, and it is dangerous.
• This inverter must be earthed (grounded). Earthing (grounding)
must conform to the requirements of national and local safety
regulations and electrical code (NEC section 250, IEC 536
class 1 and other applicable standards).

(2) Wiring
• Do not install a power factor correction capacitor, surge
suppressor or 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) Test operation and adjustment
CAUTION
CAUTION
• Before starting operation, each parameter must be confirmed
and adjusted. A failure to do so may cause some machines to
make unexpected motions.
(4) Operation
• 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.
• The inverter must be used for three-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 instructed in this
manual. Doing so may lead to fault or damage of the inverter.
WARNING
(5) Emergency stop
• A safety backup such as an emergency brake must be
provided to prevent hazardous condition to the machine and
equipment in case of inverter failure.
• 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
CAUTION
CAUTION
• Do not carry out a megger (insulation resistance) test on the
control circuit of the inverter. It will cause a failure.
(7) Disposing of the inverter
CAUTION
• The inverter must be treated as industrial waste.
General instructions
Many of the diagrams and drawings in this Instruction Manual
(basic) show the inverter without a cover or partially open for
explanation. Never operate the inverter in this manner. The
cover must be always reinstalled and the instruction in this
Instruction Manual (basic) must be followed when operating the
inverter.
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 decreases.
• The effect of electromagnetic interference must be reduced by
using a noise filter or by other means. Otherwise nearby
electronic equipment may be affected.
• Appropriate measures must be taken to suppress harmonics.
Otherwise power supply harmonics from the inverter may heat/
damage the power factor correction capacitor and generator.
• When driving a 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.
• For prevention of damage due to static electricity, nearby metal
must be touched before touching this product to eliminate
static electricity from your body.

2.4.2EMC filter
This inverter is equipped with a built-in EMC filter (capacitive filter) and common mode choke.
The EMC filter is effective for reduction of air-propagated noise on the input side of the inverter.
The EMC filter is factory-set to disable (OFF). To enable it, fit the EMC filter ON/OFF connector to the ON position.
The input side common mode choke, built-in the 55K or less inverter, is always valid regardless of ON/OFF of the EMC
filter ON/OFF connector.
The FR-F720-0.75K and 1.5K are not provided with the EMC filter ON/OFF connector. (Always ON)
<How to disconnect the connector>
(1) Before removing a front cover, check to make sure that the indication of the inverter operation panel is off, wait for
at least 10 minutes after the power supply has been switched off, and check that there are no residual voltage
using a tester or the like. (For the front cover removal method, refer to page 5.)
(2) When disconnecting the connector, push the fixing tab and pull the connector straight without pulling the cable or
forcibly pulling the connector with the tab fixed. When installing the connector, also engage the fixing tab securely.
If it is difficult to disconnect the connector, use a pair of long-nose pliers, etc.
⋅ Enabling (turning on) the EMC filter increase leakage current. (Refer to the chapter 3 of the Instruction Manual (applied))
WARNING
While power is on or when the inverter is running, do not open the front cover. Otherwise you may get an electric shock.

(2) Notes on earthing (grounding)
• Leakage currents flow in the inverter. To prevent an electric shock, the inverter and motor must be earthed (grounded). 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)
A neutral-point earthed (grounded) power supply for 400V class inverter in compliance with EN standard must be used.
• Use the dedicated earth (ground) terminal to earth (ground) the inverter.
(Do not use the screw in the casing, chassis, etc.)
• Use the thickest possible
14
, 15 and minimize the cable length. The earthing (grounding) point should be as near as possible to the inverter.
To be compliant with the EU Directive (Low Voltage Directive), earth (ground) the inverter according to
the instructions on page 155.
(3) Total wiring length
The overall wiring length for connection of a single motor or multiple motors should be within the value in the table below.

When driving a 400V class motor by the inverter, surge voltages attributable to the wiring constants may occur at the
motor terminals, deteriorating the insulation of the motor.
Take the following measures 1) or 2) in this case.
1) Use a "400V class inverter-driven insulation-enhanced motor" and set frequency in Pr. 72 PWM frequency selection
according to wiring length

2) Connect the surge voltage suppression filter (FR-ASF-H) to the 55K or less and the sine wave filter (MT-BSL/BSC)
to the 75K or more on the inverter output side.
CAUTION
· 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 or fast response current limit function or a malfunction or fault
of the equipment connected on the inverter output side. If fast-response current limit function malfunctions, disable this function.
(For Pr.156 Stall prevention operation selection, refer to the chapter 4 of the Instruction Manual (applied).)
· For details of Pr. 72 PWM frequency selection , refer to the chapter 4 of the Instruction Manual (applied). (When using an optional sine
wave filter (MT-BSL/BSC) for the 75K or more, set "25" in Pr.72 (2.5kHz)).

· Be sure to use the inverter with the jumpers across terminals R/L1-R1/L11 and S/L2-S1/L21 removed when supplying power
from other sources. The inverter may be damaged if you do not remove the jumper.
· The voltage should be the same as that of the main control circuit when the control circuit power is supplied from other than the
primary side of the MC.
· The power capacity necessary when separate power is supplied from R1/L11 and S1/L21 differs according to the inverter
capacity.

Description
Turn on the STF signal to start forward
rotation and turn it off to stop.
Turn on the STR signal to start reverse
rotation and turn it off to stop.
Turn on the STOP signal to self-hold the start signal.*2
Multi-speed can be selected according to the combination of RH,
RM and RL signals.
Turn on the JOG signal to select Jog operation (initial setting) and
turn on the start signal (STF or STR) to start Jog operation.
Turn on the RT signal to select second function.
When the second function such as "second torque boost" and
"second V/F (base frequency)" are set, turning on the RT signal
selects these functions.
Turn on the MRS signal (20ms or more) to stop the inverter
output.
Use to shut off the inverter output when stopping the motor by
electromagnetic brake.
Used to reset fault output provided when fault occurs.
Turn on the RES signal for more than 0.1s, then turn it off.
Initial setting is for reset always. By setting Pr.75, reset can be set
to enabled only at fault occurrence. Inverter recovers about 1s
after the reset is released.
Terminal 4 is valid only when the AU signal is turned on. (The
frequency setting signal can be set between 0 and 20mADC.)
Turning the AU signal on makes terminal 2 (voltage input) invalid.
AU terminal is used as PTC input terminal (thermal protection of
the motor). When using it as PTC input terminal, set the AU/PTC
switch to PTC.
When the CS signal is left on, the inverter restarts automatically at
power restoration. Note that restart setting is necessary for this
operation. In the initial setting, a restart is disabled.
(Refer to Pr. 57 Restart coasting time in the chapter 4 of the
Instruction Manual (applied).)

2.4.6Changing the control logic
The input signals are set to sink logic (SINK) when shipped from the factory.
To change the control logic, the jumper connector on the back of the control circuit terminal block must be moved to the
other position.
(The output signals may be used in either the sink or source logic independently of the jumper connector position.)
1)Loosen the two installation screws in both ends of the control circuit terminal block. (These screws cannot be
removed.)
Pull down the terminal block from behind the control circuit terminals.
2)Change the jumper connector set to the sink logic (SINK) on the rear panel of the control circuit terminal block to
source logic (SOURCE).
Jumper connector
3)Using care not to bend the pins of the inverter's control circuit connector, reinstall the control circuit terminal block
and fix it with the mounting screws.
CAUTION
1. Make sure that the control circuit connector is fitted correctly.
2. While power is on, never disconnect the control circuit terminal block.
