Safety Instructions
Please read the instructions carefully before using the equipment.
To use the equipment correctly, do not attempt to install, operate, maintain, or inspect the equipment until
you have read through this Instruction Manual, Installation guide, and appended documents carefully. Do not
use the equipment until you have a full knowledge of the equipment, safety information and instructions.
In this Instruction Manual, the safety instruction levels are classified into "WARNING" and "CAUTION".
WARNING
CAUTION
Indicates that incorrect handling may cause hazardous conditions,
resulting in death or severe injury.
Indicates that incorrect handling may cause hazardous conditions,
resulting in medium or slight injury to personnel or may cause physical
damage.
Note that the CAUTION level may lead to a serious consequence according to conditions.
Please follow the instructions of both levels because they are important to personnel safety.
What must not be done and what must be done are indicated by the following diagrammatic symbols.
Indicates what must not be done. For example, "No Fire" is indicated by
Indicates what must be done. For example, grounding is indicated by

POINT
The parameter unit cannot be used with MR Configurator2.
When using the parameter unit, set [Pr. PF34] to "1 _ _ _".
The point table mode can be used when the servo amplifier is set to the
positioning mode (point table method).
The MR-PRU03 parameter unit cannot be used with MR-J4-03A6(-RJ) servo
amplifier.
This instruction manual explains a case where the MR-PRU03 parameter unit is used with MELSERVO-J4
series. When using it with MELSERVO-J3 series, refer to each servo amplifier instruction manual.
Connecting the parameter unit to the servo amplifier enables simple execution of such as data setting, test
operation, and parameter setting without using MR Configurator2. The following shows combinations with
servo amplifiers.

6.7 Test operation mode
CAUTION
The test operation mode is designed for checking servo operation. Do not use it
for actual operation.
Before using the test operation mode for operation checks of the machine, check
safety devices such as EM2 (Forced stop 2) operate properly.
If the servo motor operates unexpectedly, use EM2 (Forced stop 2) to stop it.
POINT
Test operation cannot be performed if SON (Servo-on) is not turned off.
The single-step feed operation is only for the point table operation.
The motor-less operation cannot be used with the parameter unit although it is
displayed when the test operation mode is selected.
In this mode, you can execute the test cancel, JOG operation, positioning operation, output signal (DO)
forced output, and single-step feed. The following shows setting procedures of each operation.
When using a servo motor with an electromagnetic brake, be sure to configure the sequence so that the
electromagnetic brake operates by the MBR (Electromagnetic brake interlock) of the servo amplifier.

1. Warranty period and coverage
We will repair any failure or defect hereinafter referred to as "failure" in our FA equipment hereinafter referred to as the "Product"
arisen during warranty period at no charge due to causes for which we are responsible through the distributor from which you
purchased the Product or our service provider. However, we will charge the actual cost of dispatching our engineer for an on-site
repair work on request by customer in Japan or overseas countries. We are not responsible for any on-site readjustment and/or trial
run that may be required after a defective unit are repaired or replaced.
[Term]
The term of warranty for Product is twelve (12) months after your purchase or delivery of the Product to a place designated by you or
eighteen (18) months from the date of manufacture whichever comes first (“Warranty Period”). Warranty period for repaired Product
cannot exceed beyond the original warranty period before any repair work.
[Limitations]
(1) You are requested to conduct an initial failure diagnosis by yourself, as a general rule.
It can also be carried out by us or our service company upon your request and the actual cost will be charged. However, it will not
be charged if we are responsible for the cause of the failure.
(2) This limited warranty applies only when the condition, method, environment, etc. of use are in compliance with the terms and
conditions and instructions that are set forth in the instruction manual and user manual for the Product and the caution label
affixed to the Product.
(3) Even during the term of warranty, the repair cost will be charged on you in the following cases;
(i)
a failure caused by your improper storing or handling, carelessness or negligence, etc., and a failure caused by your
hardware or software problem
(ii) a failure caused by any alteration, etc. to the Product made on your side without our approval
(iii)
(iv)
(v)
a failure which may be regarded as avoidable, if your equipment in which the Product is incorporated is equipped with a
safety device required by applicable laws and has any function or structure considered to be indispensable according to a
common sense in the industry
a failure which may be regarded as avoidable if consumable parts designated in the instruction manual, etc. are duly
maintained and replaced
any replacement of consumable parts (battery, fan, smoothing capacitor, etc.)
(vi)
a failure caused by external factors such as inevitable accidents, including without limitation fire and abnormal fluctuation of
voltage, and acts of God, including without limitation earthquake, lightning and natural disasters
(vii) a failure generated by an unforeseeable cause with a scientific technology that was not available at the time of the shipment
of the Product from our company
(viii) any other failures which we are not responsible for or which you acknowledge we are not responsible for
2. Term of warranty after the stop of production
(1) We may accept the repair at charge for another seven (7) years after the production of the product is discontinued. The
announcement of the stop of production for each model can be seen in our Sales and Service, etc.

5. Change of Product specifications
Specifications listed in our catalogs, manuals or technical documents may be changed without notice.
6. Application and use of the Product
(1) For the use of our General-Purpose AC Servo, its applications should be those that may not result in a serious damage even if any
failure or malfunction occurs in General-Purpose AC Servo, and a backup or fail-safe function should operate on an external
system to General-Purpose AC Servo when any failure or malfunction occurs.
(2) Our General-Purpose AC Servo is designed and manufactured as a general purpose product for use at general industries.
Therefore, applications substantially influential on the public interest for such as atomic power plants and other power plants of
electric power companies, and also which require a special quality assurance system, including applications for railway companies
and government or public offices are not recommended, and we assume no responsibility for any failure caused by these
applications when used
In addition, applications which may be substantially influential to human lives or properties for such as airlines, medical treatments,
railway service, incineration and fuel systems, man-operated material handling equipment, entertainment machines, safety
machines, etc. are not recommended, and we assume no responsibility for any failure caused by these applications when used.
We will review the acceptability of the abovementioned applications, if you agree not to require a specific quality for a specific
application. Please contact us for consultation.
