MR-J3-T Servo Amplifier Specifications
The MR-J3-T servo amplifiers are a further
development of MR-J3-A. In addition to
the features of the M ELSER VO series these
amplifiers have an integrated positioning
controller for one axis.
Point to point positioning operation can
be performed just by setting position data
(target positions), servo motor speeds, and
acceleration/deceleration time constant,
etc. in the point tables as if setting them in
parameters. An additional highlight of the
servo amplifier MR-J3-T is the ”turret func-
tion”. Main focus of this function is position-
ing on different stations, which are equally
placed on a circle.
Typical applications are:
앬
Tool changer
앬
Rotary table systems
CC-Link interface can be also used for
transmitting positioning data to the
amplifier without using t he internal point
table. Hence centralised data manage
-
ment inside of a machine control can be
realised, too.
For simple servo application without any
fieldbus components internal point table
entries can be activated by serial RS-422
communication.
The table below provides an over view of
all the MR-J3-T servo amplifiers and t heir
special features.

Rated output capacity and rated rotation speed of the servo motor used in combination with the servo amplifier are as indicated when using the power voltage and frequency listed. Torque and speed cannot be
guaranteed when the power supply voltage is less than specified.
Optimal brake resistor varies for each system. Select the most suitable regenerative resistor by using the capacity selection software.
150 mA is the value when all of the input/output points are used. The current capacity can be stepped down according to the number of input/output points in use.
Refer to the MR-J3 servo instruction manual for details.
Special specification models without a dynamic brake are available on request.
The MR-J3-350T or smaller servo amplifier can be installed closely. In this case, keep the ambient temperature within 0 to 40 °C or use the servo amplifier with 75 % or less of the effective load rate.
The amplifier built-in resistor is compatible with the maximum torque deceleration when the motor isusedwithintheratedspeedandtherecommendedload/motor inertia moment ratio.
