Overview of MR-J3 Features
Compliant and Safe
Complies with global industrial
standards
Theentireproductrangecanbeusedin
confidence knowing it is in conformity
with overseas industrial standards.
An EMC filter (optional) is available for
complying with European EMC directives.
Effective EMC is only ensured if the suit-
able filter is selected for the particular sys-
tem and installed in accordance with the
Mitsubishi EMC recommendations. The
MELSERVO MR-J3 devices comply with all
important standards (CE, UL and cUL).
Enhanced ability to withstand
environmental hazards
The HF-SP motor series are equipped with
IP67 as standard enhancing their ability to
withstand environmental hazards.
The HF-MP and HF-KP series meet IP65
standard protection.
Separate wiring for the control
power supply
The control power supply of the servo
amplifier is wired separately, ensuring
diagnostics and maintenance without
connecting all power connecting cables.
Compact and flexible
More compact servo motors
Mitsubishi servo motors keep getting
smaller:

Ultra low-inertia HC-RP series
(increased capacity)
앬
Low-inertia HF-KP series
앬
Medium-inertia HF-SP series
A wide variety of motors
A broad line-up of servo motors is avail
-
able. Users can choose the motor series
that best suits the needs of the
application.
Fully Equipped
Absolute detection as standard
The MR-J3 can be easily set to absolute
system, which requires no return to home,
by merely adding a battery to the servo
amplifier and without changing the servo
motor.
Dynamic brake function
With an integrated dynamic brake, the
servo motor can be stopped quickly in a
power failure, emergency case or when an
alarm has been triggered.
Integrated regenerative resistor
A brake resistor is already integrated in
standard amplifiers, eliminating the need
for external optional brake resistors or
brake units.
Control signal assignment feature
(MR-J3-A)
Control signals necessary for operation
can be freely assigned to control terminals
within a predetermined range, enabling
more flexible operation.
Personal computer interface is
standard
The MR-J3 comes with an integrated USB
interface as standard equipment, enabling
users to connect a personal computer to
the MR-J3 to perform setup diagnostics and
maintenance by MR-Configurator.
This powerful software tool contains
numerous support functions for optimising
and analysing the servo system:
앬
Software oscilloscope
앬
Machine analyser for detecting
mechanical resonance points
앬
Control signal monitoring
앬
Encoder and servo system diagnostics
앬
Versatile test functions
앬
Gain search wizard for manual tuning
and many further useful functionalities
Special Features
Model adaptive control
As the MR-J3 operates in quick response to
commands, it offers highly responsive and
stable operation, unaffected by machine
systems.
Automatic servo motor recognition
Once the encoder cable has been con-
nected, the servo amplifier can determine,
as soon as its power is turned ON, which
servo motor is connected.
When the servo amplifier detects a mis-
match, an alarm is triggered, eliminating
the possibility of an error and the need for
setting parameters.
Encoder serial communications
The encoder uses serial communications,
so there are fewer signal wires to connect.
Real-Time Auto-Tuning (RTAT)
The servo performs automatic gain adjust-
ments even when the load changes.
