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.

1. FUNCTIONS AND CONFIGURATION

1.1 Introduction

This servo 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 255 points of point tables.

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.
