1.1 Introduction
The Mitsubishi MELSERVO-J2-Super series general-purpose AC servo is based on the MELSERVO-J2
series and has further higher performance and higher functions.
It is connected with a servo system controller or similar device via a serial bus (SSCNET) and the servo
amplifier reads position data directly to perform operation.
Data from a command unit controls the speed and rotation direction of the servo motor and executes
precision positioning.
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. The torque limit value
can be changed to any value with an external analog input or the parameter.
As this new series has the RS-232C serial communication function, a MR Configurator (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 absolute position detection system.
This makes home position return unnecessary at power-on or alarm occurrence by setting a home position
once.
