1. FUNCTIONS AND CONFIGURATION
1. FUNCTIONS AND CONFIGURATION
1.1 Introduction
The Mitsubishi MELSERVO-J3 series general-purpose AC servo has further higher performance and higher
functions compared to the current MELSERVO-J2-Super series.
The MR-J3-B servo amplifier connects to servo system controller and others via high speed synchronous
network and operates by directly reading position data. The rotation speed/direction control of servo motor and
the high accuracy positioning are executed with the data from command module. SSCNET
MR-J3-B servo amplifier greatly improved its communication speed and noise tolerance by adopting optical
communication system compared to the current SSCNET. For wiring distance, 50m of the maximum distance
between electrodes is also offered.
The torque limit with clamping circuit is put on the servo amplifier in order to protect the power transistor of
main circuit from the overcurrent caused by rapid acceleration/deceleration or overload. In addition, torque limit
value can be changed to desired value in the controller.
As this new series has the USB 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 is 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.

motor shaft varies. Higher in performance than MR-J2-Super series servo
amplifier.
Used when the regenerative option cannot provide enough regenerative
power.
Can be used the 5kW or more servo amplifier.
Used when the regenerative option cannot provide enough regenerative
power.
Can be used the 5kW or more servo amplifier.
Used when the built-in regenerative resistor of the servo amplifier does not
have sufficient regenerative capability for the regenerative power generated.
Output signal can be forced on/off independently of the servo status.
Use this function for output signal wiring check, etc.
