shock.
To prevent an electric shock, always connect the protective earth (PE) terminal (terminal marked ) of the
servo amplifier with the protective earth (PE) of the control box.
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.
Always connect a circuit protector between the power supply and power supply voltage input terminals (24,
0, and M) 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 circuit protector 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.
Provide adequate protection to prevent screws and other conductive matter, oil and other combustible
matter from entering the servo amplifier and servo motor.
Always connect a molded-case circuit breaker to the power supply of the servo amplifier.

1. FUNCTIONS AND CONFIGURATION
1.1 Summary
The Mitsubishi AC servo amplifier MELSERVO-J3W series is an AC servo that requires less space, less wiring,
and less energy while it maintains high performance, functionality and usability of MELSERVO-J3-B.
Two servo motors can be driven by this MR-J3W servo amplifier. Driving two servo motors by one MR-J3W
servo amplifier cuts down the installation area compared to the area required for two MR-J3 servo amplifiers.
Side-by-side installation is also available, making the system more compact.
Integrated 2-axis structure allows two axes to share the same SSCNET
cable, control circuit power cable, and
main circuit power cable, cutting down the wiring area.
The capacitor in the MELSERVO-J3W series is re-charged, doubling the reusable energy compared to it of the
MELSERVO-J3 series. Regenerative energy is generated during deceleration of a servo motor. By reusing that
energy, much energy is saved. Depending on the operating condition, the regenerative option may be disabled.
The MR-J3W-77B servo amplifier has a 100W regenerative resistor built in, making the regenerative option
unnecessary even for a large regenerative load.
By simply shifting the switch, a rotary servo motor, a linear servo motor or a direct drive motor can be used for
each axis for the MR-J3W servo amplifier. A rotary servo motor, a linear servo motor and a direct drive motor
with different capacities can be connected to the MR-J3W-22B and MR-J3W-44B servo amplifier axes.
Using MELSERVO-J3W makes the linear servo motor and the direct drive motor structure simple and the
equipment compact with high performance. Using MELSERVO-J3W also saves the space.
As explained above, integrated 2-axis structure, multi-function, and improved regeneration efficiency reduce the
required parts for a servo system.
