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, when confirming whether the charge lamp is off or
not, always confirm it from the front of the servo amplifier.
Ground the servo amplifier and servo motor securely.
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, it
may cause an electric shock.
Do not operate switches with wet hands. Otherwise, it may cause an electric shock.
The cables should not be damaged, stressed, loaded, or pinched. Otherwise, it may cause an electric
shock.
During power-on or operation, do not open the front cover of the servo amplifier. Otherwise, it may cause
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 and periodic inspection, do not remove the front cover of the servo amplifier even if the
power is off. The servo amplifier is charged and you may get an electric shock.
To prevent an electric shock, always connect the protective earth (PE) terminal (marked ) of the servo
amplifier to the protective earth (PE) of the cabinet.
When using an earth-leakage current breaker (RCD), select the type B.
To avoid an electric shock, insulate the connections of the power supply terminals.
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 between the power supply and the main circuit power supply (L1,
L2, and L3) of the servo amplifier, in order to configure a circuit that shuts down the power supply on the
side of the servo amplifier’s power supply. If a magnetic contactor is not connected, continuous flow of a
large current may cause a fire when the servo amplifier malfunctions.
When using the regenerative resistor, switch power off with the alarm signal. Not doing so may cause a
fire when a regenerative transistor malfunctions or the like may overheat the regenerative resistor.
Provide adequate protection to prevent screws and other conductive matter, oil and other combustible
matter from entering the servo amplifier, servo motor, and MR-J3-T10.
Always connect a molded-case circuit breaker to the power supply of the servo amplifier.

3. To prevent injury, note the following
CAUTION
Only the voltage specified in the Instruction Manual should be applied to each terminal. Otherwise, a
burst, damage, etc. may occur.
Connect cables to the correct terminals. Otherwise, a burst, damage, etc. may occur.
Ensure that polarity (+/-) is correct. Otherwise, a burst, damage, etc. may occur.
The servo amplifier heat sink, regenerative resistor, servo motor, etc. may be hot while power is on or for
some time after power-off. Take safety measures, e.g. provide covers, to avoid accidentally touching the
parts (cables, etc.) by hand.
4. Additional instructions
The following instructions should also be fully noted. Incorrect handling may cause a malfunction, injury,
electric shock, etc.
(1) Transportation and installation
CAUTION
Transport the products correctly according to their mass.
Stacking in excess of the specified number of product packages is not allowed.
Do not hold the front cover when transporting the servo amplifier. Otherwise, it may drop.
Install the servo amplifier and the servo motor in a load-bearing place in accordance with the Instruction
Manual.
Do not get on or put heavy load on the equipment.
The equipment must be installed in the specified direction.
Leave specified clearances between the servo amplifier and the cabinet walls or other equipment.
Do not install or operate the servo amplifier and MR-J3-T10 which have been damaged or have any
parts missing.
Do not block the intake and exhaust areas of the servo amplifier and MR-J3-T10. Otherwise, it may
cause a malfunction.
Do not drop or strike the servo amplifier, servo motor, and MR-J3-T10. Isolate them from all impact
loads.
When you keep or use the equipment, please fulfill the following environment.
Item Environment

Vibration resistance 5.9 m/s2, at 10 Hz to 55 Hz (directions of X, Y and Z axes)
When the product has been stored for an extended period of time, contact your local sales office.
When handling the servo amplifier and MR-J3-T10, be careful about the edged parts such as corners of
them.
The servo amplifier and MR-J3-T10 must be installed in a metal cabinet.
When fumigants that contain halogen materials such as fluorine, chlorine, bromine, and iodine are used
for disinfecting and protecting wooden packaging from insects, they cause malfunction when entering our
products. Please take necessary precautions to ensure that remaining materials from fumigant do not
enter our products, or treat packaging with methods other than fumigation (heat method).Additionally,
disinfect and protect wood from insects before packing products.

(2) Wiring
CAUTION
Wire the equipment correctly and securely. Otherwise, the servo motor may operate unexpectedly.
Do not install a power capacitor, surge killer, or radio noise filter (FR-BIF-(H) option) on the servo
amplifier output side.
To avoid a malfunction, connect the wires to the correct phase terminals (U, V, and W) of the servo
amplifier and servo motor.
Connect the servo amplifier power output (U, V, and W) to the servo motor power input (U, V, and W)
directly. Do not let a magnetic contactor, etc. intervene. Otherwise, it may cause a malfunction.

When the cable is not tightened enough to the terminal block, the cable or terminal block may generate
heat because of the poor contact. Be sure to tighten the cable with specified torque.
Connecting a servo motor for different axis to U, V, W, or CN2 of the servo amplifier may cause a
malfunction.
(3) Test run and adjustment
CAUTION
Before operation, check the parameter settings. Improper settings may cause some machines to operate
unexpectedly.
Never make a drastic adjustment or change to the parameter values as doing so will make the operation
unstable.
Do not close to moving parts at servo-on status.
(4) Usage
CAUTION
When it is assumed that a hazardous condition may occur due to a power failure or product malfunction,
use a servo motor with an external brake to prevent the condition.
Do not disassemble, repair, or modify the equipment.

A - 5
(4) Usage
CAUTION
Before resetting an alarm, make sure that the run signal of the servo amplifier is off in order to prevent a
sudden restart. Otherwise, it may cause an accident.
Use a noise filter, etc. to minimize the influence of electromagnetic interference. Electromagnetic
interference may be given to the electronic equipment used near the servo amplifier.
Burning or breaking a servo amplifier may cause a toxic gas. Do not burn or break it.
Use the servo amplifier with the specified servo motor.
The electromagnetic brake on the servo motor is designed to hold the motor shaft and should not be
used for ordinary braking.
For such reasons as service life and mechanical structure (e.g. where a ball screw and the servo motor
are coupled via a timing belt), the electromagnetic brake may not hold the motor shaft. To ensure safety,
install a stopper on the machine side.
(5) Corrective actions
CAUTION
When it is assumed that a hazardous condition may occur due to a power failure or product malfunction,
use a servo motor with an electromagnetic brake or external brake to prevent the condition.
Configure an electromagnetic brake circuit so that it is activated also by an external EMG stop switch.

When any alarm has occurred, eliminate its cause, ensure safety, and deactivate the alarm before
restarting operation.
Provide an adequate protection to prevent unexpected restart after an instantaneous power failure.
(6) Maintenance, inspection and parts replacement
CAUTION
With age, the electrolytic capacitor of the servo amplifier will deteriorate. To prevent a secondary
accident due to a malfunction, it is recommend that the electrolytic capacitor be replaced every 10 years
when it is used in general environment. Please contact your local sales office.
(7) General instruction
To illustrate details, the equipment in the diagrams of this Instruction Manual may have been drawn
without covers and safety guards. When the equipment is operated, the covers and safety guards must
be installed as specified. Operation must be performed in accordance with this Instruction Manual.
