1. To prevent electric shock, note the following:
WARNING
Before wiring or inspection, turn off the power and wait for 15 minutes or more until the charge lamp turns
off. Then, confirm that the voltage between P and N is safe with a voltage tester and others. Otherwise, an
electric shock may occur. In addition, always confirm from the front of the servo amplifier, whether the
charge lamp is off or not.
Connect the servo amplifier and servo motor to ground.
Any person who is involved in wiring and inspection should be fully competent to do the work.
Do not attempt to wire the servo amplifier and servo motor until they have been installed. Otherwise, you
may get an electric shock.
Operate the switches with dry hand to prevent an electric shock.
The cables should not be damaged, stressed, loaded, or pinched. Otherwise, you may get an electric shock.
During power-on or operation, do not open the front cover of the servo amplifier. You may get an electric
shock.
Do not operate the servo amplifier with the front cover removed. High-voltage terminals and charging area
are exposed and you may get an electric shock.
Except for wiring or periodic inspection, do not remove the front cover even of the servo amplifier if the
power is off. The servo amplifier is charged and you may get an electric shock.
2. To prevent fire, note the following:
CAUTION
Install the servo amplifier, servo motor and regenerative resistor on incombustible material. Installing them
directly or close to combustibles will lead to a fire.
Always connect a magnetic contactor (MC) between the main circuit power supply and L1, L2, and L3 of
the servo amplifier, and configure the wiring to be able to shut down the power supply on the side of the
servo amplifier’s power supply. If a magnetic contactor (MC) is not connected, continuous flow of a large
current may cause a fire when the servo amplifier malfunctions.
When a regenerative resistor is used, use an alarm signal to switch main power off. Otherwise, a
regenerative transistor fault or the like may overheat the regenerative resistor, causing a fire.
3. To prevent injury, note the follow
CAUTION
Only the voltage specified in the Instruction Manual should be applied to each terminal, Otherwise, a
burst, damage, etc. may occur.
Connect the terminals correctly to prevent a burst, damage, etc.
Ensure that polarity ( ,
) is correct. Otherwise, a burst, damage, etc. may occur.
Take safety measures, e.g. provide covers, to prevent accidental contact of hands and parts (cables, etc.)
with the servo amplifier heat sink, regenerative resistor, servo motor, etc. since they may be hot while
power is on or for some time after power-off. Their temperatures may be high and you may get burnt or a
parts may damaged.
During operation, never touch the rotating parts of the servo motor. Doing so can cause injury.

2.5 Signals and wiring
Any person who is involved in wiring should be fully competent to do the work.
WARNING
Before wiring, turn off the power and wait for 15 minutes or more until the charge
lamp turns off. Then, confirm that the voltage between P and N is safe with a
voltage tester and others. Otherwise, an electric shock may occur. In addition,
always confirm from the front of the servo amplifier whether the charge lamp is off
or not.
Ground the servo amplifier and the servo motor securely.
Do not attempt to wire the servo amplifier and servo motor until they have been
installed. Otherwise, you may get an electric shock.
The cables should not be damaged, stressed excessively, loaded heavily, or
pinched. Otherwise, you may get an electric shock.
Wire the equipment correctly and securely. Otherwise, the servo motor may
misoperate, resulting in injury.
Connect cables to correct terminals to prevent a burst, fault, etc.
Ensure that polarity ( ,
) is correct. Otherwise, a burst, damage, etc. may occur.
The surge absorbing diode installed to the DC relay designed for control output
should be fitted in the specified direction. Otherwise, the signal is not output due to
a fault, disabling the emergency stop (EMG) and other protective circuits.

Use a noise filter, etc. to minimize the influence of electromagnetic interference,
which may be given to electronic equipment used near the servo amplifier.
Do not install a power capacitor, surge suppressor or radio noise filter (FR-BIF-H
option) with the power line of the servo motor.
When using the regenerative resistor, switch power off with the alarm signal.
Otherwise, a transistor fault or the like may overheat the regenerative resistor,
causing a fire.
Do not modify the equipment.

2.5.2 Input power supply circuit
WARNING
Insulate the connections of the power supply terminals to prevent an electric
shock.
Always connect a magnetic contactor (MC) between the main circuit power supply
and L1, L2, and L3 of the servo amplifier, and configure the wiring to be able to shut
down the power supply on the side of the servo amplifier’s power supply. If a
magnetic contactor (MC) is not connected, continuous flow of a large current may
cause a fire when the servo amplifier malfunctions.
CAUTION
Use the trouble (ALM) to switch power off. Otherwise, a regenerative transistor
fault or the like may overheat the regenerative resistor, causing a fire.
Connect the wires to the correct phase terminals (U, V, W) of the servo amplifier
and servo motor. Otherwise, the servo motor will operate improperly.
Do not connect AC power supply directly to the servo motor. Otherwise, a fault
may occur.
POINT
Do not apply the test lead bars or like of a tester directly to the pins of the
connectors supplied with the servo motor. Doing so will deform the pins,
causing poor contact.

(3) Power-on sequence
(a) Power-on procedure
1) Always wire the power supply as shown in above section 2.5.2(1) using the magnetic contactor
with the main circuit power supply (three-phase 400V: L1, L2, L3). Configure up an external
sequence to switch off the magnetic contactor as soon as an alarm occurs.
2) Switch on the control circuit power supply L11, L21 simultaneously with the main circuit power
supply or before switching on the main circuit power supply. If the main circuit power supply is
not turned on in the servo-on state, a warning is shown at the display. However, after the main
circuit is turned on, the warning disappears and the servo amplifier will operate properly.
3) The servo amplifier can accept the servo-on (SON) about 1 to 2s after the main circuit power
supply is switched on. Therefore, when SON is switched on simultaneously with the main circuit
power supply, the base circuit will switch on in about 1 to 2s, and the ready (RD) will switch on
in further about 20ms, making the servo amplifier ready to operate. (Refer to paragraph (b) in
this section.)
4) When the reset (RES) is switched on, the base circuit is shut off and the servo motor shaft
coasts.

3.5 Signals and wiring
Any person who is involved in wiring should be fully competent to do the work.
WARNING
Before wiring, turn off the power and wait for 15 minutes or more until the charge
lamp turns off. Then, confirm that the voltage between P and N is safe with a
voltage tester and others. Otherwise, an electric shock may occur. In addition,
always confirm from the front of the servo amplifier whether the charge lamp is off
or not.
Ground the servo amplifier and the servo motor securely.
Do not attempt to wire the servo amplifier and servo motor until they have been
installed. Otherwise, you may get an electric shock.
The cables should not be damaged, stressed excessively, loaded heavily, or
pinched. Otherwise, you may get an electric shock.
Wire the equipment correctly and securely. Otherwise, the servo motor may
misoperate, resulting in injury.
Connect cables to correct terminals to prevent a burst, fault, etc.
Ensure that polarity ( ,
) is correct. Otherwise, a burst, damage, etc. may occur.
The surge absorbing diode installed to the DC relay designed for control output
should be fitted in the specified direction. Otherwise, the signal is not output due to
a fault, disabling the forced stop (EM1) and other protective circuits.

Use a noise filter, etc. to minimize the influence of electromagnetic interference,
which may be given to electronic equipment used near the servo amplifier.
Do not install a power capacitor, surge suppressor or radio noise filter (FR-BIF-H
option) with the power line of the servo motor.
When using the regenerative resistor, switch power off with the alarm signal.
Otherwise, a transistor fault or the like may overheat the regenerative resistor,
causing a fire.
Do not modify the equipment.

3.5.2 Input power supply circuit
WARNING
Insulate the connections of the power supply terminals to prevent an electric
shock.
Always connect a magnetic contactor (MC) between the main circuit power supply
and L1, L2, and L3 of the servo amplifier, and configure the wiring to be able to shut
down the power supply on the side of the servo amplifier’s power supply. If a
magnetic contactor (MC) is not connected, continuous flow of a large current may
cause a fire when the servo amplifier malfunctions.
CAUTION
Use the trouble (ALM) to switch power off. Otherwise, a regenerative transistor
fault or the like may overheat the regenerative resistor, causing a fire.
Connect the wires to the correct phase terminals (U, V, W) of the servo amplifier
and servo motor. Otherwise, the servo motor will operate improperly.
Do not connect AC power supply directly to the servo motor. Otherwise, a fault
may occur.
POINT
Do not apply the test lead bars or like of a tester directly to the pins of the
connectors supplied with the servo motor. Doing so will deform the pins,
causing poor contact.

5. CHARACTERISTICS
5.1 Overload protection characteristics
An electronic thermal relay is built in the servo amplifier to protect the servo motor and servo amplifier
from overloads. Overload 1 alarm (AL.50) occurs if overload operation performed is above the electronic
thermal relay protection curve shown in any of Figs 5.1. Overload 2 alarm (AL.51) occurs if the maximum
current flew continuously for several seconds due to machine collision, etc. Use the equipment on the lefthand side area of the continuous or broken line in the graph.
In a machine like the one for vertical lift application where unbalanced torque will be produced, it is
recommended to use the machine so that the unbalanced torque is 70% or less of the rated torque.

Note. If operation that generates torque more than 100% of the rating is performed with an abnormally high frequency in a servo motor stop
status (servo lock status) or in a 30r/min or less low-speed operation status, the servo amplifier may fail even when the electronic

5.2 Power supply equipment capacity and generated loss
(1) Amount of heat generated by the servo amplifier
Table 5.1 indicates servo amplifiers' power supply capacities and losses generated under rated load.
For thermal design of an enclosure, use the values in Table 5.1 in consideration for the worst
operating conditions. The actual amount of generated heat will be intermediate between values at
rated torque and servo off according to the duty used during operation. When the servo motor is run at
less than the maximum speed, the power supply capacity will be smaller than the value in the table,
but the servo amplifier's generated heat will not change.

Since large inrush currents flow in the power supplies, always use no-fuse breakers and magnetic
contactors. (Refer to section 6.2.2.)
When circuit protectors are used, it is recommended to use the inertia delay type that will not be tripped
by an inrush current.

To use a regenerative resistor for the servo amplifier, the specified number of resistors (4 or 5
resistors) must be connected in series. If they are connected in parallel or in less than the specified
number, the servo amplifier may become faulty and/or the regenerative resistors burn. Install the

Note. The number of resistors connected in series depends on the resistor type. Install a thermal sensor or like to configure a
circuit that will shut off the main circuit power at abnormal overheat. The supplied regenerative resistor does not have a builtin thermal sensor. If the regenerative brake circuit fails, abnormal overheat of the resistor is expected to occur. On the
customer side, please also install a thermal sensor for the resistor and provide a protective circuit that will shut off the main
circuit power supply at abnormal overheat. The detection level of the thermal sensor changes depending on the resistor

6.1.2 FR-BU2-H brake unit
POINT
Use a 400V class brake unit and a resistor unit with a 400V class servo
amplifier. Combination of different voltage class units and servo amplifier
cannot be used.
Install a brake unit and a resistor unit on a flat surface vertically. When
the unit is installed horizontally or diagonally, the heat dissipation effect
diminishes.
Temperature of the resistor unit case rises to higher than 100 . Keep
cables and flammable materials away from the case.
Ambient temperature condition of the brake unit is between 10 (14 )
and 50 (122 ). Note that the condition is different from the ambient
temperature condition of the servo amplifier (between 0 (32 ) and
55 (131 )).
Configure the circuit to shut down the power-supply with the alarm
output of the brake unit and resistor unit under abnormal condition.
Use the brake unit with a combination indicated in (1) of this section.
For executing a continuous regenerative operation, use FR-RC-H power
regeneration converter.
Brake unit and regenerative options (Regenerative resistor) cannot be
used simultaneously.
Connect the brake unit to the bus of the servo amplifier. As compared to the MR-RB regenerative option,
the brake unit can return larger power. Use the brake unit when the regenerative option cannot provide
sufficient regenerative capability.
When using the brake unit, set the parameter of servo amplifier as indicated below.

(c) Precautions for wiring
The cables between the servo amplifier and the brake unit, and between the resistor unit and the
brake unit should be as short as possible. Always twist the cable longer than 5m (twist five times
or more per one meter). Even when the cable is twisted, the cable should be less than 10m. Using
cables longer than 5m without twisting or twisted cables longer than 10m, may result in the brake
unit malfunction.

Configure up a sequence which switches off the contact of the brake unit
after (or as soon as) it has turned off the servo on (son) at a power failure
or failure.
For the braking time taken when the dynamic brake is operated, refer to
section 5.3.
The brake unit is rated for a short duration. Do not use it for high duty.
When using the 400V class dynamic brake, the power supply voltage is
restricted to 1-phase 380VAC to 463VAC (50Hz/60Hz).
The dynamic brake is designed to bring the servo motor to a sudden stop when a power failure occurs or
the protective circuit is activated.

6.1.5 Heat sink outside mounting attachment (MR-JACN)
Use the heat sink outside mounting attachment to mount the heat generation area of the servo amplifier
in the outside of the control box to dissipate servo amplifier-generated heat to the outside of the box and
reduce the amount of heat generated in the box, thereby allowing a compact control box to be designed.
In the control box, machine a hole having the panel cut dimensions, fit the heat sink outside mounting
attachment to the servo amplifier with the fitting screws (4 screws supplied), and install the servo
amplifier to the control box.
The environment outside the control box when using the heat sink outside mounting attachment should
be within the range of the servo amplifier operating environment conditions.

(1) Selection method
High-frequency chopper currents controlled by pulse width modulation flow in the AC servo circuits.
Leakage currents containing harmonic contents are larger than those of the motor which is run with a
commercial power supply.
Select a leakage current breaker according to the following formula, and ground the servo amplifier,
servo motor, etc. securely.
Make the input and output cables as short as possible, and also make the grounding cable as long as
possible (about 30cm (11.8 in)) to minimize leakage currents.
