CAUTION
y Securely attach the servo motor to the machine. If attach insec urely, the servo motor m ay come off dur ing
operation.
y The servo motor with reduction gear must be installed in the specified direction to prevent oil leakage.
y For safety of personnel, always cover rotating and moving parts.
y Never hit the servo motor or shaft, espec ially when coupling the servo motor to the mac hine. The encoder

(4) Usage
CAUTION
y Provide an external emergency stop circuit to ensure that operation can be stopped and power switched off
immediately.
y Any person who is involved in disassembly and repair should be fully competent to do the work.
y Before resetting an alarm, m ake sure that the run signal is off to prevent an accident. A sudden r estart is
made if an alarm is reset with the run signal on.
y Do not modify the equipment.
y Use a noise filter, etc. to minimize the influence of electrom agnetic interference, which m ay be caused by
electronic equipment used near the servo amplifier.
y Use the servo amplifier with the specified servo motor.
y The electromagnetic br ak e on the ser vo m otor is designed to hold the m otor shaft and s hould not be used
for ordinary braking.
y For such reasons as s er vice lif e and mechanical struct ure ( e.g. where a ballsc r ew and the s ervo motor are
coupled via a timing belt), the electromagnetic brake may not hold the motor shaft. T o ens ur e safety, install
a stopper on the machine side.
(5) Corrective a ctions
CAUTION
y When it is ass umed that a hazardous condition may take place at the occur due to a power failure or a
product fault, use a servo motor with electromagnetic brake or an external brake mechanism for the
purpose of prevention.
y When any alarm has occurred, eliminate its cause, ensure safety, and deactivate the alarm before
restarting operation.
y When power is r estored after an instantaneous power f ailure, keep away from the m achine because the
machine may be restarted suddenly (design the machine so that it is secured against hazard if restarted).
(6) Maintenance, inspection and parts replacement
CAUTION
y With age, the electrolytic capacitor will deteriorate. To prevent a secondary accident due to a fault, it is
recommended to replace the electrolytic capacitor every 10 years when used in general environment.

COMPLIANCE WITH EC DIRECTIVES
1. WHAT ARE EC DIRECTIVES?
The EC Directives were issued to standardize the regulations of the EU countries and ensure smooth
distribution of safety-guaranteed products. In the EU countries, the Machinery Directive (effective in
January, 1995), EMC Directive (effective in January, 1996) and Low Voltage Directive (effective in
January, 1997) of the EC Directives require that p ro du cts to be sold sho uld mee t their f und ame ntal saf ety
requirements and carry the CE marks (CE marking). CE marking applies to machines and equipment into
which servo amplifiers have been installed.
The servo amplifiers do not funct ion independentl y but a re designed for us e with ma chines and eq uipment.
Therefore, the CE marking does not apply to the servo amplifiers but applies to the machines and
equipment into which the servo amplifiers are installed.
This servo amplifier conforms to the standards related to the Low Voltage Directive to facilitate CE
marking on machines and equipment in to which the servo amplifiers will be installed. To ensure ease of
compliance with the EMC Directive, Mitsubishi Electric prepared the "EMC INSTALLATION
GUIDELINES" (IB(NA)67310) which prov ides servo amplifier installation, control bo x making and other
procedures. Please contact your sa les repres enta t ive.
2. PRECAUTIONS FOR COMPLIANCE
The standard models of the servo amplifier and servo motor comply with the EN Standard. In addition to
the instructions provided in this In structio n Manual, also fo llo w the in structio ns below . If the mode l is no t

install the servo amplifier in a co ntrol box wh ich is pro tected against w ater, oil, carbon, du st, dirt, etc.
(IP54).
(3) Power supply
Use a 24VDC power supply which ha s b een ins ul at ion-rei nforced in I/ O.
(4) Grounding
To prevent an electric shock, fit the supplied earth terminal (E) to the servo amplifier and always
connect it to the earth (E) of the control box.
A - 7
(5) Auxiliary equipment and options
(a) The circuit protector used should be the EN or IEC Standard-compliant product of the model
described in Section 12.2.2.
(b) The sizes of the cables described in Section 12.2.2 meet the following requirements. To meet the
other requirements, follow Table 5 and Appendix C in EN60204.
y Ambient temperature: 40 (104) [°C (°F)]
y Sheath: PVC (polyvi nyl chl oride)
y Installed on wall s urfa ce or open t ab le t ra y
(6) Performing EMC tests
When EMC tests are run on a machine/device into which the servo amplifier has been installed, it must
conform to the e lectromagnetic compatibility (immunity /emission) standards after it has satisfied the
operating environment/electrica l eq uipment s pecifi cat i ons.
For the other EMC Directive guidelines on the servo amplifier, refer to the "EMC INSTALLATION
GUIDELINES".

1. FUNCTIONS AND CONFIGURATION
1.FUNCTIONS AND CONFIGURATION
1.1 Introduction
The MELSERVO-J2-Jr series general-purpose AC servo has been developed as an ultracompact, small
capacity servo system compatible with the MELSERVO-J2 series 24VDC power supply. It can be used in a
wide range of fields from semiconductor equipment to s ma ll robots , etc.
The input signals of t he s ervo ampl if ier cont rol s ys tem a re compat i bl e wit h th ose of t he M R-J 2- A.
As the standard models comply with the EN Standard x UL/C-UL Standard, they can be used satisfactorily
in various countries.
The MR-J2-03A5 servo amplifier can be easily installed to a control box with a DIN rail.
The power supply/electromagnetic brake and encoder of the servo motor can be wired easily with a single
cable.
Using a personal computer where the Servo Configuration software has been installed, you can make
parameter setting, status display, etc.
Also, you can use the RS-422 communication function to set up to 32 axes of servo amplifiers.
The compatible servo motors have achieved the smallest 28mm-bore flange size in this class and are
further equipped with encoders of 8192 pulses/rev (incremental) resolution.

(3) Avoid any probability that the cable sheath might be cut by sharp chips, rubbed by a machine corner or
stamped by workers or vehicles.
(4) For in stallation on a machine where the se rvo motor will move, the flexing radius should be made as
large as possible. Refer t o sect ion 1 1. 4 for t he flexi ng li fe.

3. SIGNALS AND WIRING
Note: 1. To prevent an electric shock, fit the supplied earth terminal (E) to the servo amplifier and always
connect it to the earth (E) of the cont rol box. (Refer t o section 3 .9.)
2. Connect th e diode in the correct dire ction. If it is connected rev ersely, the servo amplifier w ill be
faulty and will not output signals, disabling the forced stop and other protective circuits.
3. The forced stop switch must be installed.
4. CN1A and CN1B have the same shape. Wrong connection of the connectors will lead to a fault.
5. When starting operation, always connect the forward/reverse rotation stroke end signal (LSN/LSP)
with SG. (Normally closed contacts)
6. Trouble (ALM) is connected with COM in normal alarm-free condition.
7. The pins with the same signal na me are connected in t he servo ampl ifier.
8. For the command pulse train input of the differential line driver system. 2m max. for the open
collector system.
9. Use MRZJW3-SETUP61E or later.
