18.1 Functions and configuration
18.1.1 Summary
MR-J4-03A6 servo amplifier is MELSERVO-J4 series 48 V DC and 24 V DC power compatible ultra-small
capacity servo amplifier.
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 following shows the differences with 100 W or more MR-J4-_A_(-RJ) servo amplifier.
