Japan Industrial Standards (JIS)*1) and other safety regulations*2).
*1) ISO 4414: Pneumatic fluid power -- General rules relating to systems
ISO 4413: Hydraulic fluid power -- General rules relating to systems
IEC 60204-1: Safety of machinery -- Electrical equipment of machines (Part 1: General requirements)
ISO 10218-1992: Manipulating industrial robots -- Safety
JIS B 8370: General rules for pneumatic equipment.
JIS B 8361: General rules for hydraulic equipment.
JIS B 9960-1: Safety of machinery –Electrical equipment for machines. (Part 1: General requirements)
JIS B 8433-1993: Manipulating industrial robots - Safety. etc.
*2) Labor Safety and Sanitation Law, etc.
Caution
Caution indicates a hazard with a low level of risk which, if not avoided, could result in minor or
moderate injury.
Warning
Warning indicates a hazard with a medium level of risk which, if not avoided, could result in death
or serious injury.
Danger
Danger indicates a hazard with a high level of risk which, if not avoided, will result in death or
serious injury.
Warning
1. The compatibility of the product is the responsibility of the person who designs the equipment or
decides its specifications.
Since the product specified here is used under various operating conditions, its compatibility with specific
equipment must be decided by the person who designs the equipment or decides its specifications based
on necessary analysis and test results.
The expected performance and safety assurance of the equipment will be the responsibility of the person
who has determined its compatibility with the product.
This person should also continuously review all specifications of the product referring to its latest catalog
information, with a view to giving due consideration to any possibility of equipment failure when
configuring the equipment.
2. Only personnel with appropriate training should operate machinery and equipment.
The product specified here may become unsafe if handled incorrectly.
The assembly, operation and maintenance of machines or equipment including our products must be
performed by an operator who is appropriately trained and experienced.
3. Do not service or attempt to remove product and machinery/equipment until safety is confirmed.
The inspection and maintenance of machinery/equipment should only be performed after measures to
prevent falling or runaway of the driven objects have been confirmed.
When the product is to be removed, confirm that the safety measures as mentioned above are
implemented and the power from any appropriate source is cut, and read and understand the specific
product precautions of all relevant products carefully.
Before machinery/equipment is restarted, take measures to prevent unexpected operation and
malfunction.
4. Contact SMC beforehand and take special consideration of safety measures if the product is to
be used in any of the following conditions.
1) Conditions and environments outside of the given specifications, or use outdoors or in a place exposed
to direct sunlight.
2) Installation on equipment in conjunction with atomic energy, railways, air navigation, space, shipping,
vehicles, military, medical treatment, combustion and recreation, or equipment in contact with food and
beverages, emergency stop circuits, clutch and lock circuits in press applications, safety equipment or
other applications unsuitable for the standard specifications described in the product catalog.

- 4 -
3) An application which could have negative effects on people, property, or animals requiring special
safety analysis.
4) Use in an interlock circuit, which requires the provision of double interlock for possible failure by using
a mechanical protective function, and periodical checks to confirm proper operation.
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.

consult your nearest sales branch.
For any failure or damage reported within the warranty period which is clearly our responsibility, a
replacement product or necessary parts will be provided.
This limited warranty applies only to our product independently, and not to any other damage
incurred due to the failure of the product.
Prior to using SMC products, please read and understand the warranty terms and disclaimers noted
in the specified catalog for the particular products.
*3) Vacuum pads are excluded from this 1 year warranty.
A vacuum pad is a consumable part, so it is warranted for a year after it is delivered.
Also, even within the warranty period, the wear of a product due to the use of the vacuum pad or failure due
to the deterioration of rubber material are not covered by the limited warranty.
Compliance Requirements
When the product is exported, strictly follow the laws required by the Ministry of Economy, Trade and
Industry (Foreign Exchange and Foreign Trade Control Law).

Introduction
It is recommended that the operator read the operation manual for LECSB prior to use.
For the handling and details of other equipment, please refer to the operation manual for used equipment.
Check that the main circuit power supply (AC100V/AC200V) and controller circuit power supply
(AC100V/AC200V) are wired correctly.
Please refer to chapter 3.1 of the “LECSB Operation Manual” and chapter 3 of the “LECSB Operation
Manual (Simplified Edition)”for details.
Please put the wiring for EMG (Emergency stop) into the state of EMG release (operational).
However, EMG (Emergency stop) cannot be compulsorily set to automatic ON by the parameter.
When setup software (MR Configurator2TM) is used, the LECSB model selection is required.
Select 'MR-J3-A' through “Model" - "New" and "Project".
Term
Position control mode
Control the motor rotation speed/direction and execute precision
positioning/stopping with high-speed pulse train.

5. Parameter Configuration using Setup software (MR Configurator2TM)
This section describes the configuration procedure for main parameters using the setup software (MR
Configurator2TM: LEC-MRC2E). See chapter 5 of the “LECSB Operation Manual” for parameter details.
5.1 Setup software (MR Configurator2TM)
*1 Setup software version 1.19V or above is required.
*2 The setup software (MR Configurator2TM : LEC-MRC2E) must be purchased as an additional item.
*3 The USB cable (LEC-MR-J3USB) must be purchased as an additional item.
5.1.1 Installation Method
Perform installation according to the “MR Configurator2TM instruction manual” (Manual/ib0300160*.pdf) contained on
the setup software (MR Configurator2TM) CD-ROM. The “MR Configurator2TM” software will be added to the PC.
5.2 Basic driver set-up for Initial Test Drive
Switch on the main circuit power supply (AC100V/AC200V) and controller circuit power supply
(AC100V/AC200V) to the LECSB driver.
When the driver display flashes as shown below, it wires for EMG (Emergency stop) and ON (state of EMG
release (operational)). However, EMG (Emergency stop) cannot be compulsorily set to automatic ON by
the parameter.
If you turn on the power supply for the first time, refer to "LECSB Operation Manual”, chapter 4.

5.2.1 Start up the Setup software (MR Configurator2TM)
①Connect the PC and LECSB using the USB cable.
②Turn on the power of the LECSB.
③Start application “MR Configurator2”.
Once the application starts, the screen below will be displayed.
