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.
To prevent an electric shock, always connect the protective earth (PE) terminal (marked ) of the servo
amplifier to the protective earth (PE) of the control box.
When using an earth-leakage current breaker (RCD), select 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 smoke or a fire.
Always connect a magnetic contactor between the power supply and the power supply (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 is not connected, continuous flow of a large
current may cause smoke or 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 smoke or a fire.
In order to configure a circuit that shuts down the power supply on the side of the servo amplifier’s power
supply, always connect one molded-case circuit breaker or fuse per one servo amplifier between the
power supply and the main circuit power supply (L1, L2, and L3) of a servo amplifier. If a molded-case
circuit breaker or fuse is not connected, continuous flow of a large current may cause smoke or a fire
when the servo amplifier malfunctions.
Provide adequate protection to prevent screws and other conductive matter, oil and other combustible
matter from entering the servo amplifier and servo motor.

1. FUNCTIONS AND CONFIGURATION
1. FUNCTIONS AND CONFIGURATION
1.1 Introduction
The MR-J3- T CC-Link compatible servo amplifier can support the CC-Link communication functions. Up to 42
axes of servo amplifiers can be controlled/monitored from the programmable controller side.
As the servo, it has the function to perform positioning operation by merely setting the position data (target
positions), servo motor speeds, acceleration and deceleration time constants, etc. to point tables as if setting
them in parameters. The servo amplifier is the most appropriate to configure a program-free, simple positioning
system or to simplify a system, for example.
There are 31 points of point tables to be used when 1 station is occupied and 255 points when 2 stations are
occupied.
All servo motors are equipped with an absolute position encoder as standard. An absolute position detection
system can be configured by merely adding a battery to the servo amplifier. Once the home position has been
set, home position return is not required at power on, alarm occurrence, etc.
The MR-J3-T is made easier to use and higher in function by using it with the MR Configurator.
1.1.1 Features of CC-Link communication functions
(1) Fast communication
Fast communication can be made by cyclic transmission of not only bit data but also word data.
(a) The highest communication speed is 10Mbps.
(b) The broadcast polling system ensures as high as 3.9ms to 6.7ms even at the maximum link scan
(10Mbps).
(2) Variable communication speed/distance system
Selection of speed/distance allows use in a wide range of areas from a system requiring high speed to a
system requiring long distance.
(3) System fault prevention (station separating function)
Because of connection in the bus system, any remote or local station that has become faulty due to power-
off or the like does not affect communications with normal remote and local stations.
In addition, use of the two-piece terminal block allows the unit to be changed during data link.
(4) Factory Automation compatible
As the remote device stations of CC-Link, the servo amplifiers share a link system and can be
controlled/monitored with programmable controller user programs.
From the programmable controller side, the running speed, acceleration/deceleration time constant and
other settings of servo motors can be changed/checked and the servo motors started and stopped.
