1. FUNCTIONS AND CONFIGURATION
1. FUNCTIONS AND CONFIGURATION
1.1 Introduction
The Mitsubishi MELSERVO-J2-Super series general-purpose AC servo is ba sed on the MELSERVO-J2
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 RS-232C or RS-422 serial communication function, a MR Conf igurator (servo
configuration software)-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-J2-Super series servo motor is equipped with an absolute position encoder which has
the resolution of 131072 pulses/rev to ensure more accurate control as compared to the MELSERVO-J2
series. Simply adding a battery to the servo amplifier makes up an abso lute position dete ction 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 500kpps high-speed pulse train is used to control the speed and direction of a motor and
execute precision positioning of 131072 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 lim it is imposed on th e se rv o amp l if ier by the clamp circuit to p ro te c t the powe r transisto r 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
(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 an alog torque command (0 to
used to control the torque output by the servo motor.
To protect misoperation under no load, the speed limit function (external or internal setting) is also
available for application to tension control, etc.

Using external input signal, control can be switched
between pos i tion control and speed control.
Using external input signal, control can be switched
between speed control and torque control.
Using external input signal, control can be switched
between to rque control a nd position control.
High-resolution encoder of 131072 pulses/rev is used as a
servo motor encoder.
Merely setting a home position once makes home position
return unnecessary at every power-on.
You can switch between gains during rotation and gains
during stop or use an external signal to change gains
during operation.
Servo amplifier detects mechanical resonance and sets filter
characteristics automatically to suppress mechanical
vibration.
Suppresses high-frequency resonance which occurs as servo
system response is increased.
Analyzes the frequency characteristic of the mechanical
system by simply connecting a MR Configurator (servo
configuration) software-installed personal computer and
servo amplifier.
Can simulate machine motions on a personal computer
screen on the basis of the machine analyzer results.
Personal computer changes gains automatically and
searches for overshoot-free gains in a short time.
Suppresses vibration of 1 pulse produced at a servo motor
stop.
Automatically adjusts the gain to optimum value if load
applied to the servo motor shaft varies. Higher in
performance than MR-J2 series servo amplifier.
Speed can be increased and decreased smoothly.S, TParameter No. 13
Used when the built-in regenerative brake resistor of the
servo amplifier does not have sufficient regenerative
capability for the regenerative power generated.
Used when the regenerative brake option cannot provide
