1. To prevent electric shock, note the following

WARNING

Before wiring or inspection, turn off the power and wait for 15 minutes or more (20 minutes or for drive

unit 30kW or more) until the charge lamp turns off. Then, confirm that the voltage between P(

) and

N(

) (L and L for drive unit 30kW or more) 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 (converter unit),

whether the charge lamp is off or not.

Connect the converter unit, servo amplifier (drive unit) 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 converter unit, servo amplifier (drive unit) 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. You may get an electric shock.

Do not operate the converter unit and servo amplifier (drive unit) 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 if the power is off. The servo

amplifier (drive unit) is charged and you may get an electric shock.

2. To prevent fire, note the following

CAUTION

Install the converter unit, servo amplifier (drive unit), 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 main circuit power supply and L1, L2, and L3 of the

converter unit, servo amplifier (drive unit), and configure the wiring to be able to shut down the power

supply on the side of the converter unit, servo amplifier (drive unit) power supply. If a magnetic contactor

is not connected, continuous flow of a large current may cause a fire when the converter unit, servo

amplifier (drive unit) 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.

Provide adequate protection to prevent screws and other conductive matter, oil and other combustible

matter from entering the converter unit, servo amplifier (drive unit), and servo motor.

Always connect a no-fuse breaker to the power supply of the servo amplifier (converter unit).

1. FUNCTIONS AND CONFIGURATION

1.1 Summary

The Mitsubishi MELSERVO-J3 series general-purpose AC servo is based on the MELSERVO-J2-Super series

and has further higher performance and higher functions.

It has position control, speed control and torque control modes. Further, it can perform operation with the

control modes changed, e.g. position/speed control, speed/torque control and torque/position control. Hence, it

is applicable to a wide range of fields, not only precision positioning and smooth speed control of machine tools

and general industrial machines but also line control and tension control.

As this new series has the USB or RS-422 serial communication function, a MR Configurator installed personal

computer or the like can be used to perform parameter setting, test operation, status display monitoring, gain

adjustment, etc.

With real-time auto tuning, you can automatically adjust the servo gains according to the machine.

The MELSERVO-J3 series servo motor with an absolute position encoder which has the resolution of 262144

pulses/rev to ensure more accurate control as compared to the MELSERVO-J2-Super series. Simply adding a

battery to the servo amplifier makes up an absolute position detection system. This makes home position

return unnecessary at power-on or alarm occurrence by setting a home position once.

(1) Position control mode

An up to 1Mpps high-speed pulse train is used to control the speed and direction of a motor and execute

precision positioning of 262144 pulses/rev resolution.

The position smoothing function provides a choice of two different modes appropriate for a machine, so a

smoother start/stop can be made in response to a sudden position command.

A torque limit is imposed on the servo amplifier by the clamp circuit to protect the power transistor in the

main circuit from overcurrent due to sudden acceleration/deceleration or overload. This torque limit value

can be changed to any value with an external analog input or the parameter.

(2) Speed control mode

An external analog speed command (0 to

10VDC) or parameter-driven internal speed command (max. 7

speeds) is used to control the speed and direction of a servo motor smoothly.

There are also the acceleration/deceleration time constant setting in response to speed command, the

servo lock function at a stop time, and automatic offset adjustment function in response to external analog

speed command.

(3) Torque control mode

An external analog torque command (0 to

8VDC) is used to control the torque output by the servo motor.

To prevent unexpected operation under no load, the speed limit function (external or internal setting) is also

available for application to tension control, etc.
