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.
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.

Other than positioning mode, EM2 can not be forcibly set to automatic ON with parameters.
Sure to set the EM2 wiring to the ON : EM2 release (operable) state.
When setup software (MR Configurator 2TM ) is used, it is necessary to select the LECSB2-T□ model.
Select "MR-J4-A-S099(□)" *1) through Project (P) - "New (N)" - "Model".
*1) This product can be used by adding "MR Configurator2 dedicated file for LECSB-T" to Setup software(MR
Configurator2TM:LEC-MRC2□).
Please download the dedicated file from SMC website.
"LECSB2-T□ Operation Manual, section 17.1 " for how to add and operate dedicated files.
Terms
Position control mode (pulse input)
Positioning is performed by controlling the rotation speed and direction
of the motor with a pulse train.
Speed control mode
Runs at the set rotation speed using parameters or analog input
commands.
Torque control mode
Operation is executed with the set output torque by the analog input
command.
Positioning mode (point table)
Position data, rotation speed, acceleration/deceleration time constant,
etc. are set in the point table of the driver, and I/O signal ON/OFF
control positioning operation is executed. (Up to 255 points can be
used in the point table.)
Positioning mode (program method)
Multiple operation method settings are preset in the driver as steps
with program, and I/O signal ON/OFF control positioning operation is
executed. (The maximum number of steps is 640.)
Positioning mode (equally divided
indexing method) (Note)
Presetting the number of equal divisions of 360 degrees for one
rotation of the machine end, and I/O signal ON/OFF control positioning
operation is executed. (Maximum number of divisions: 255 divisions)
Positioning mode
(pushing operation)
A series of operations from positioning to pushing operation is
executed using the positioning mode of point table.
Note) The positioning mode (equally divided indexing method) is not described in this Operation Manual
(Simplified Edition).
When using the positioning mode (equally divided indexing method), refer to ``LECS B2 -T□ Operation
Manual, Chapter 16.17 ''.

3. Wiring
3.1 Power Supply Wiring
Connect the actuator and driver power supply. This wiring diagram is common for each mode.
(1) LECSB2-T□(Absolute encoder)
Example) When the power supply voltage is AC200V single-phase/sink input/output interface
[1] Power supply input terminals: Supply specified power (single -phaseAC200to 240V) to L1and L3.
[2] - Connect the power input terminals (U, V, W ) of the motor to the power terminals (U, V, W ) of the
driver.
- Connect the ground terminal of the motor to the ground terminal of the driver.
- Connect the encoder cable.
[3] Connect the single -phaseAC200to 240V external power supply to the power supply for control circuit.
[4] Connect the DC24V power supply to the interface power supply.
Refer to "LECSB2-T□ Operation Manual, Chapter 3" when the power supply voltage is 3-phase AC200V or
source I/O interface.
Note 1.
P3 and P4 are already connected at the time of shipment.
2.
Always connect between P+ and D. (Wiring is completed at the time of shipment.)
4.
This is for the sink I/O interface.
6.
Use a magnetic contactor with an operation delay time (the time from when current flows through the operation coil until the
contact closes) of 80 ms or less. Depending on the voltage of the main circuit and the operation pattern, the bus voltage may
drop and the deceleration may shift to dynamic brake deceleration during forced stop deceleration. If you do not want dynamic
brake deceleration, delay the time to turn off the magnetic contactor.
7.
To prevent an unexpected restart of the driver, configure a circuit that turns off EM2 when the main circuit power is turned off.
8.
When not using the STO function, attach the short-circuit connector that comes with the driver.
9.
If the wire used for L11 and L21 is thinner than the wire used for L1 and L3, use a no-fuse circuit breaker.
10..
Do not connect the servo motor of the wrong axis to U, V, W and CN2 of the driver as it may cause malfunction.
11.
For convenience, the DC24 V power supplies for input signals and output signals are shown separately, but they can be
configured with a single unit.

- 10 -
3.2 Connection of I/O signals
An example of connecting the input/output signals of the driver is shown.
3.2.1 Position control mode (sink input/output interface)
(1) Connection example
An example of connection in position control mode is shown below.
For the source I/O interface, please refer to "LECSB2-T□ Operation Manual Chapter 3.2.1 (2)".
For notes and wiring details, please refer to "LECSB2-T□ Operation Manual Chapter 3.2.1 (1)".
For input/output signals, refer to "LECSB2-T□ Operation Manual (Simplified Edition), Chapter 3.2.1 (2), (3)". For
details, refer to "LECSB2-T□ Operation Manual Chapter 3.5".
This connection example is for use with Mitsubishi Electric Corporation's PLC/positioning unit
(RD75D/LD75D/QD75D) when used in position control mode.
When connecting with other PLCs/positioning units, please check the "LECSB2-T□instruction
manual" and the technical data/manuals of the PLC and positioning unit you are using.

5. Parameter setting from setup software (MR Configurator2TM)
The procedure for setting typical parameters from the setup software (MR Configurator2 TM: LEC-MRC2*) is
explained. For details of parameters, refer to "LECSB2-T Operation Manual, Chapter 5 ".
5.1 Setup software (MR Configurator 2TM)
*1 Setup software version 1.52E or higher is required.
*2 Prepare the setup software (MR Configurator2TM: LEC-MRC2*) separately.
*3 Prepare the USB cable (LEC-MR-J3USB) separately.
5.1.1 Installation Method
" MR Configurator2TM Operation Manual" in the " Setup Software (MR Configurator2TM) " CD
("Manual¥ ib0300160 *.pdf ") to install the " setup software (MR Configurator2TM) ".
After the installation is completed, a software called “MR Configurator2” will be added to your PC.
5.2 Driver basic settings for first commissioning
Turn on the main circuit power supply (AC 200V) and control power supply (AC 200V) of the LECSB2-T.
the driver display is as shown below, set the EM2 (forced stop 2 ) wiring to ON : Forced stop canceled
(operable).
Refer to "LECSB2-T□ Operation Manual, Chapter 4 " when turning on the power for the first time.
This product can be used by adding the "MR Configurator2 dedicated file for LECSB-T" to the setup software
(MRConfigurator2TM: LEC-MRC2□).
Please download the dedicated file from our website.
