may result in injury or property damage.
The items under this heading contain important handling instructions that the user should
observe to ensure safe use of the product.
General
•Do not use the product in explosive or corrosive environments, in the presence of ammable gases, locations
subjected to splashing water, or near combustibles. Doing so may result in re, electric shock or injury.
•Assign qualied personnel the task of installing, wiring, operating/controlling, inspecting and troubleshooting the
product. Failure to do so may result in re, electric shock or injury.
•Do not transport, install the product, perform connections or inspections when the power is on. Always turn the
power o before carrying out these operations. Failure to do so may result in electric shock.
•After turning o the power supply, wait at least 10 seconds before installing, inspecting or troubleshooting the
product. Failure to do so may result in electric shock.
•The terminals on the driver’s front panel marked with symbol indicate the presence of high voltage. Do not
touch these terminals while the power is on to avoid the risk of re or electric shock.
•If the driver’s protective function is actuated, the lineard motor current will be cut o and the motor will stop. Once
the motor has stopped, do not apply any load that will move the rack. Doing so may result in injury or equipment
damage.
•When the driver-protection function is triggered, the lineard motor will stop and lose its holding torque, possibly
causing injury or damage to equipment.
•When the driver’s protection function is triggered, rst remove the cause and then clear the protection function.
Continuing the operation without removing the cause of the problem may cause malfunction of the lineard motor
and driver, leading to injury or damage to equipment.
•Use a lineard motor with an electromagnetic brake for a lift device. In the event of power failure or actuation of the
driver’s protective function, turn o the power to the electromagnetic brake to hold the rack by means of the
electromagnetic brake. Failure to do so may result in injury or equipment damage.
•Do not use the electromagnetic brake of a lineard motor with an electromagnetic brake as a safety brake for your
equipment. This electromagnetic brake is designed to hold the lineard motor rack and moving part in position.
Using it as a safety brake may result in injury or equipment damage.
Installation
•Use the lineard motor and driver for class I equipment only to prevent electric shock or injury.
•To prevent the risk of electric shock, install the lineard motor and driver in their enclosures.
•Install the lineard motor and driver so as to avoid contact with hands, or ground them to prevent the risk of electric
shock.
Connection
•Keep the driver’s input-power voltage within the specied range to avoid re and electric shock.
•Connect the cables securely according to the wiring diagram in order to prevent re and electric shock.
•Do not process or modify the cables of the lineard motor or any extension cable (sold separately) connected to it.
Fire or electric shock may result.
•Do not forcibly bend, pull or pinch any of the power cables and lineard motor cables. Fire or electric shock may
result.
•Securely connect the driver’s protective ground terminal to the grounding point. Failure to do so may result in
electric shock.
•Upon completion of connection, always install a terminal cover over the power terminals on the driver. Failure to
do so may result in electric shock.

Safety precautions
5▐
Operation
•When operating the lineard motor, pay attention to the speed and travel amount settings. Use appropriate settings
to prevent the rack from coming o. The maximum operating speed of the rack is 500 mm/s. If the travel amount
or acceleration/deceleration time is not set properly, the rack will not stop even after a limit sensor is detected. As a
result, the rack may come o and cause injury or equipment damage.
•Turn o the driver power in the event of a power failure, or the lineard motor may suddenly start when the power
is restored and may cause injury or damage to equipment.
•Do not turn the C.OFF (All windings o) input “ON”while the lineard motor is operating. If this input is turned ON,
the lineard motor will stop and the holding force will be lost. As a result, the rack may drop and cause injury or
equipment damage.
Maintenance and inspection
•Do not touch the connection terminals of the driver immediately after the driver power is turned o (for a period
of 10 seconds). The residual voltage may cause electric shock.
Repair, disassembly and modication
•Do not disassemble or modify the lineard motor or driver. This may cause electric shock or injury. Refer all such
internal inspections and repairs to the branch or sales oce from which you purchased the product.
General
•Do not use the lineard motor and driver beyond their specications, or electric shock, injury or damage to
equipment may result.
•Keep your ngers and objects out of the openings in the driver, or electric shock, injury or damage to equipment
may result.
•Occasionally the grease applied to the rack may drip or a small amount of grease may ooze out from the rack. If
there is concern over possible environmental damage resulting from the leakage of grease, check for grease stains
during regular inspections. Alternatively, install an oil pan or other device to prevent leakage from causing further
damage. Oil leakage may lead to problems in the customer’s equipment or products.
Transportation
•Do not hold the lineard motor by the rack, motor or cables alone. The lineard motor or rack may drop, resulting in
injury.
Installation
•Keep the area around the lineard motor and driver free of combustible materials in order to prevent re or a burn.
•To prevent the risk of damage to equipment, leave nothing around the lineard motor and driver that would
obstruct ventilation.
•Securely ax the lineard motor onto a grounded metal plate. Failure to do so may result in electric shock, injury or
equipment damage.
•Provide a cover for the rack of the lineard motor. Failure to do so may result in injury.
Operation
•Use a lineard motor and driver only in the specied combination. An incorrect combination may cause a re.
•Provide an emergency-stop device or emergency-stop circuit external to the equipment so that the entire
equipment will operate safely in the event of a system failure or malfunction. Failure to do so may result in injury.
•Before supplying power to the driver, turn all control inputs to the driver to“OFF.” Otherwise, the lineard motor may
start suddenly and cause injury or damage to equipment.
•Before moving the rack directly (as in the case of manual positioning), conrm that the driver C.OFF (All windings
o) input is“ON” to prevent injury.
•Do not touch the rack (especially the tooth surface) while the motor is operating. Injury may result.
•Immediately when trouble has occurred, stop running and turn o the driver power. Failure to do so may result in
re, electric shock or injury.
•The lineard motor’s surface temperature may exceed 70 °C (158 °F), even under normal operating
conditions. If a lineard motor is accessible during operation, post a warning label shown in the
gure in a conspicuous position to prevent the risk of burns.
•To prevent electric shock, use only an insulated screwdriver to adjust the internal switches. Warning label
•For the control input/output signal power supply, use a power supply with reinforced insulation provided on the
primary side, and provide it separately from the power supply for the electromagnetic brake. Failure to do so may
result in electric shock.
•Do not touch the lineard motor or the driver while the driver is conducting current. The surface is hot and may
cause a burn.

Safety precautions
▌6
Maintenance and inspection
•To prevent the risk of electric shock, do not touch the terminals while measuring the insulation resistance or
conducting a voltage-resistance test.
Disposal
•To dispose of the lineard motor or driver, disassemble it into parts and components as much as possible and
dispose of individual parts/components as industrial waste.

Precautions for use
7▐
3 Precautions for use
This section covers limitations and requirements the user should consider when using the LAS series.
zConduct the insulation resistance measurement or withstand voltage test separately on the lineard
motor and the driver.
Conducting the insulation resistance measurement or withstand voltage test with the lineard motor and driver
connected may result in injury or damage to equipment.
zOperate the motor at or below the maximum thrust force.
If the motor is operated while receiving a load beyond the maximum thrust force, the rack tooth surface or pinion
may be damaged. Therefore, always operate the lineard motor under a load not exceeding the maximum thrust.
zDo not apply an overhung load in excess of the specied permissible limit.
If the motor is operated continuously under an overhang load exceeding the permissible limit, the rack bushings may
be worn quickly or even damaged. Always keep the overhang load to the permissible limit or below.
Even if the overhang load is kept to the permissible limit or below, repeated operation of the lineard motor will still
cause the rack bushings to wear. To suppress rack bush wear, install a guide, etc., to reduce the overhang load or
rotational torque.
zDo not stop the rack by means of contact.
Never allow the moving rack to contact a hard object. The shock may damage the rack tooth surface, pinion and/or
gear.
zReversing the rack
Be sure to reverse the lineard motor before either end of the rack enters the rack bushing. The rack operates properly
when being supported by the rack bushings on both sides of the rack case.
zInstalling sensors
A desired rack travel amount can be specied accurately using pulse signals. However, also install sensors to detect
the home of the equipment and the rack end and process sensor signals on the controller side.
zPositioning direction
Stop the motor always from the same direction, as it will suppress the negative impact of rack and pinion backlash
and consequently improve the stopping accuracy.
zLubricating the rack
Do not wipe grease o the rack surface or the tooth surface meshing with the pinion. Grease is pre-charged in the
rack case before shipment. If grease is wiped o, the rack and pinion life will become shorter. Always keep the rack
surface and tooth surface properly greased during operation.
If the rack is used in a lift device or at a high ambient temperature, grease may drip. If dripping grease becomes a
concern, place an oil pan underneath the rack.
zOperate the lineard motor with a surface temperature of the motor not exceeding 100 °C (212 °F).
The driver has an overheat-protection function, but the lineard motor has no such feature. The lineard motor case’s
surface temperature may exceed 100 °C (212 °F) under certain conditions (ambient temperature, operating speed,
duty cycle, etc.). Keeping the surface temperature of the motor casing below 100 °C (212 °F) will also maximize the life
of the motor bearings (ball bearings).
zUse an electromagnetic brake type for an application involving vertical travel.
For a lifter or any other lift device, use a lineard motor with an electromagnetic brake to hold the load and rack in
position. Always wait for the lineard motor to stop rst, and then use the electromagnetic brake to hold the rack. Do
not use the electromagnetic brake for braking/stop operation. If used in such application, the brake hub of the
electromagnetic brake will wear quickly and the braking force will drop.
Since the electromagnetic brake is of the non-excitation type, it can also be used to hold the load in position upon the
occurrence of a power failure. However, this is not a secure means of holding the load. Do not use the electromagnetic
brake as a safety brake.
When the driver-protection function is triggered, the lineard motor stops as the current is turned o. The user must
set a controller sequence that will cut o the power to the electromagnetic brake and hold the load in position upon
detecting an ALARM output.

Precautions for use
▌8
zConnecting an electromagnetic brake lineard motor
When using an electromagnetic brake lineard motor, provide a power supply for the electromagnetic brake separately
from the control input/output signal power supply. Always use an optional extension cable of the electromagnetic
brake type when connecting the lineard motor to the driver. The electromagnetic brake will not function if the motor
cable is connected directly to the driver.
The electromagnetic brake operates via the ON/OFF status of the DC power supply. Be sure to connect the lead wires
from the relay cable in the correct polarities. Also, always connect the supplied varistor (non-polar type) to protect the
switch contacts and prevent noise.
zInstall the driver in a vertical orientation.
The driver’s heat-dissipation function is designed according to vertical orientation. Installing the driver in any other
orientation may shorten the life of electronic parts due to temperature increases within the driver.
zPreventing leakage current
Stray capacitance exists between the driver’s current-carrying line (power supply, lineard motor) and other current-
carrying lines, the earth and the motor, respectively. A high-frequency current may leak out through such capacitance,
having a detrimental eect on the surrounding equipment. The actual leakage current depends on the driver’s
switching frequency, the length of wiring between the driver and motor, and so on.
When providing a leakage current breaker, use the following products, for instance, which have high-frequency signal
protection:
Mitsubishi Electric Corporation: NV series
Fuji Electric FA Components & Systems Co., Ltd.: EG and SG series
zPreventing electrical noise
See “5-5 Installing and wiring in compliance with the EMC Directive” on p.18 for measures with regard to noise.

5 Installation
This section covers the lineard motor and driver’s installation location and method, as well as the method of installing
a load.
5-1 Location for installation
The lineard motor and driver are designed and manufactured for use as a built-in component in industrial equipment.
Install it in a well-ventilated place satisfying the following conditions, where the product can be easily accessed for
the purpose of inspection.
•Inside an enclosure installed indoors (with ventilation hole provided)
•Ambient temperature Lineard motor: 0 to +50 °C (+32 to +122 °F) (non-freezing)
Driver: 0 to +50 °C (+32 to +122 °F) (non-freezing)
•Ambient humidity: 85% or less (non-condensing)
•Area that is free of explosive atmosphere or toxic gas (such as sulfuric gas) or liquid
•Area not exposed to direct sun
•Area free of excessive amount of dust, iron particles or the like
•Area not subject to splashing water (rains, water droplets), oil (oil droplets) or other liquids
•Area free of excessive salt
•Area not subject to continuous vibration or excessive shocks
•Area free of excessive electromagnetic noise (from welders, power machinery, etc.)
•Area free of radioactive materials, magnetic elds or vacuum
5-2 Installing the lineard motor
Install the lineard motor using the mounting feet, or mounting holes provided on the front face.
Securely ax the lineard motor to a grounded metal plate.
•If a lineard motor without an electromagnetic brake is used and the linear head is oriented in such
a way that the rack moves up/down, place a buer material, etc., underneath to prevent damage
caused by a falling load or rack. A lineard motor without an electromagnetic brake has no function
to retain the rack. Accordingly, the load or rack may drop and cause injury in the event of actuation
of the driver’s protective function or power failure.
•If you are using a photomicrosensor, install it after installing the lineard motor.
Installation using a mounting foot
1. Drill mounting holes or tapped holes in the metal plate used to install the lineard motor.

supplied) through the tapped holes provided on the end face
of the rack. When installing the load, always secure the rack
with a wrench so that the rack will not receive rotational force
while the load is axed.

* The above values are valid up to an operating speed of 90 mm/s. If the motor is operated at any higher speed, do
not apply overhang load. If an overhang load is to be applied, provide an external guide, etc.
•Be sure to keep the overhang load to the permissible limit or below. An excessive overhang load
may cause the rack bushes to wear quickly or sustain damage.
•Even if the overhung load does not exceed the permissible value, it is recommended to still install
a guide, etc., to reduce or disperse the overhung load.
Maximum rotational torque (moment)
Keep the rotational torque received by the rack to or below the permissible value, as applicable, specied in the table.
Lineard motor model Permissible rotational torque
(moment) on rack
LAS2B(F) 0.3 N·m (2.6 lb-in) or less
LAS4B(F) 0.5 N·m (4.4 lb-in) or less
Be sure to keep the rotational torque to the permissible limit or below. If the rack receives excessive
rotational torque, the rack bushing will wear quickly.

Gap along the rack
There is a slight gap between the rack and rack bushing of the lineard motor. The initial gap dimensions are specied
in the table below.

B
D
C
Moving direction Gap (initial dimension)
A, B direction 2 mm (0.08 in.) or less
C direction 0.5 mm (0.02 in.) or less
D direction 0.5° or less
The above gap dimensions in directions A and B are measured at 500 mm (19.69 in.) from the end face of the case on
the linear head.
As the motor is operated repeatedly, the rack bushing will wear and the gap along the rack will increase.
To suppress rack bushing wear, install a guide, etc., to reduce the overhung load or rotational torque.
5-4 Installing the driver
Installation direction
The driver is designed so that heat is dissipated via air convection and
conduction through the enclosure.
There must be a clearance of at least 25 mm (0.98 in.) in the horizontal and
vertical directions, respectively, between the driver and enclosure or other
equipment within the enclosure. When two or more drivers are to be installed
side by side, provide 20 mm (0.79 in.) and 25 mm (0.98 in.) clearances in the
horizontal and vertical directions, respectively.

5-5 Installing and wiring in compliance with the EMC Directive
Introduction
zEMC Directive
The LAS series has been designed and manufactured for incorporation in general industrial machinery. The EMC
Directive requires that the equipment incorporating this product comply with these directives. The installation and
wiring method for the lineard motor and driver are the basic methods that would eectively allow the customer’s
equipment to be compliant with the EMC Directive.
The conformance of your mechanical equipment with the EMC Directive will vary depending on such factors as the
conguration, wiring, and layout for other control system devices and electrical parts used with this product. It
therefore must be veried through conducting EMC measures in a state where all parts including this product have
been installed in the equipment.
zApplicable Standards
EMI
EN 61000-6-4
EN 61800-3
EN 55011 group 1 class A
EN 61000-3-2
EN 61000-3-3
EMS EN 61000-6-2
EN 61800-3
This product is not intended to be used on a low-voltage public network which supplies domestic premises; radio
frequency interference is expected if used on such a network.
Installing and wiring in compliance with the EMC Directive
Eective measures must be taken against the EMI that the Eective measures must be taken against the EMI that the
control-system equipment, as well as the EMS of the LAS series itself, in order to prevent a serious functional
impediment in the machinery.
The use of the following installation and wiring methods will enable the LAS series to be compliant with the EMC
Directive (the aforementioned compliance standards).
zConnecting mains lter for power supply line
Connect a mains lter in the AC input line to prevent the noise generated in the driver from propagating externally
through the power supply line. Use a mains lter or equivalent as below table.
Manufacturer Single-phase 100-115 V
Single-phase 200-230 V Three-phase 200-230 V
Schaner EMC FN2070-10-06 FN3025HP-10-71
SOSHIN ELECTRIC CO., LTD. HF2010A-UPF HF3010C-SZA
•Install the mains lter as close to the driver as possible, and use cable clamps and other means to secure the input
and output cables rmly to the surface of the enclosure.
•Connect the ground terminal of the mains lter to the grounding point, using as thick and short a wire as possible.
•Do not place the AC input cable (AWG18: 0.75 mm2or more) parallel with the mains-lter output cable (AWG18:
0.75 mm2or more). Parallel placement will reduce mains-lter eectiveness if the enclosure’s internal noise is
directly coupled to the power supply cable by means of stray capacitance.
zConnecting surge arrester
Use a surge arrester or equivalent as below table.
Manufacturer Single-phase 100-115 V Single-phase 200-230 V

OKAYA ELECTRIC INDUSTRIES CO., LTD. R·A·V-781BWZ-4 R·A·V-781BXZ-4
When measuring dielectric strength of the equipment, be sure to remove the surge arrester, or the
surge arrester may be damaged.

zPower supply for electromagnetic brake (for electromagnetic brake lineard motor only)
If an external DC power supply is required for the use of the electromagnetic brake, use a DC power supply that
complies with the EMC Directive. Use a shielded cable for wiring, and keep the wiring and grounding as short as
possible. Refer to“Wiring the signal cable”for details on how to ground the shielded cable.
zHow to ground
The cable used to ground the driver, lineard motor and mains lter must be as thick and short as possible so that no
potential dierence is generated. Choose a large, thick and uniformly conductive surface for the grounding point.
Refer to p.27 for the way to ground.
zWiring the signal cable
Use a shielded cable of AWG24 (0.2 mm2) or more for the driver signal cable, and keep it as short as possible.
Driver cavle is available as an accessory. Refer to p.43.
To ground a shielded cable, use a metal clamp or similar device that will
maintain contact with the entire circumference of the shielded cable.
Attach a cable clamp as close to the end of the cable as possible, and
connect it as shown in the gure.
Shielded cable
Cable clamp
zNotes about installation and wiring
•Connect the lineard motor, driver and other peripheral control equipment directly to the grounding point so as to
prevent a potential dierence from developing between grounds.
•When relays or electromagnetic switches are used together with the system, use mains lters and CR circuits to
suppress surges generated by them.
•Keep cables as short as possible without coiling and bundling extra lengths.
•Place the power cables such as the motor and power supply cables as far apart [100 to 200 mm (3.94 to 7.87 in.)] as
possible from the signal cables. If they have to cross, cross them at a right angle. Place the AC input cable and
output cable of a mains lter separately from each other.
•If an extension cable is required between the lineard motor and driver, it is recommended that an optional
extension cable (sold separately) be used, since the EMC measures are conducted using the Oriental Motor
extension cable.

zPrecautions about static electricity
Static electricity may cause the driver to malfunction or suer damage. Be careful when handling the driver with the
power on. Always use an insulated screwdriver to adjust the driver’s switches.
The driver uses parts that are sensitive to electrostatic charge. Take measures against static electricity
since static electricity may cause the driver to malfunction or suer damage.
