1. To prevent electric shock, note the following
WARNING
Before wiring and inspections, turn off the power and wait for 15 minutes or more until the charge lamp
turns off. 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.
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.
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, 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 smoke or a fire when the servo amplifier malfunctions.
Always connect a molded-case circuit breaker, or a fuse to each servo amplifier 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 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.
When using the regenerative resistor, switch power off with the alarm signal. Otherwise, a regenerative
transistor malfunction or the like may overheat the regenerative resistor, causing smoke or a fire.
When you use a regenerative option with an MR-JE-40A to MR-JE-100A, remove the built-in
regenerative resistor and wiring from the servo amplifier.
Provide adequate protection to prevent screws and other conductive matter, oil and other combustible
matter from entering the servo amplifier and servo motor.
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.

1. FUNCTIONS AND CONFIGURATION
1.1 Summary
The Mitsubishi general-purpose AC servo MELSERVO-JE series have limited functions with keeping high
performance based on MELSERVO-J4 series.
The servo amplifier has position, speed, and torque control modes. In the position control mode, the
maximum pulse train of 4 Mpulses/s is supported. Further, it can perform operation with the control modes
switched, 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.
With one-touch tuning and real-time auto tuning, you can automatically adjust the servo gains according to
the machine.
The tough drive function, drive recorder function, and preventive maintenance support function strongly
support machine maintenance.
The servo amplifier has a USB communication interface. Therefore, you can connect the servo amplifier to
the personal computer with MR Configurator2 installed to perform the parameter setting, test operation, gain
adjustment, and others.
The MELSERVO-JE series servo motor equipped with an incremental encoder whose resolution is 131072
pulses/rev will enable a high-accuracy positioning.
