Handling the product without observing the instructions that accompany a“Caution”symbol
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

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.
