cable.

Risk of electric shock, wire breakage, contact failure and loss of control of
the product can happen.

 Select “Robotic cables” in case of inflecting cable (encoder/ motor/

rock) repeatedly.

Refer to the “Driver operation manual” for the bending life due to the

bending radius of the cable.

2 General Instructions (continued)

 Confirm correct insulation of the product.

Poor insulation of wires, cables, connectors, terminals etc. can cause
interference with other circuits. Also there is the possibility that excessive
voltage or current may be applied to the product causing damage.

2.2 Transportation

Caution

 Do not carry or swing the product by the cables.

2.3 Mounting

Warning

 Observe the tightening torque for screws.

Unless stated otherwise, tighten the screws to the recommended torque
for mounting the product.

 Do not make any alterations to this product.

Alterations made to this product may lead to a loss of durability and
damage to the product, which can lead to human injury and damage to
other equipment and machinery.

 When an external guide is used, connect the moving parts of the

product and the load in such a way that there is no interference at
any point within the stroke.

Do not scratch or dent the sliding parts of the table or mounting face etc.,
by striking or holding them with other objects. The components are
manufactured to precise tolerances, so that even a slight deformation
may cause faulty operation or seizure.

 Do not use the product until you verify that the equipment can be

operated correctly.

After mounting or repair, connect the power supply to the product and
perform appropriate functional inspections to check it is mounted
correctly.

 When attaching to the work piece, do not apply strong impact or

large moment.

If an external force over the allowable moment is applied, it may cause
looseness in the guide unit, an increase in sliding resistance or other
problems.

 Maintenance space
Allow sufficient space for maintenance and inspection.

2.4 Handling

Warning

 Do not touch the motor while in operation.

The surface temperature of the motor can increase to approx. 80°C due
to operating conditions.
Energizing alone may also cause this temperature increase.
As it may cause burns, do not touch the motor when in operation.

 If abnormal heating, smoking or fire, etc. occurs in the product,

immediately turn off the power supply.

 Immediately stop operation if abnormal operation noise or vibration

occurs.

If abnormal operation noise or vibration occurs, the product may have
been mounted incorrectly. Unless operation of the product is stopped for
inspection, the product can be seriously damaged.

 Never touch the rotating part of the motor or the moving part of the

actuator while in operation.

There is a serious risk of injury.

 When installing, adjusting, inspecting or performing maintenance

on the product, driver and related equipment, be sure to turn off the
power supply to each of them. Then, lock it so that no one other
than the person working can turn the power on, or implement
measures such as a safety plug.

Caution

 Keep the driver and product combined as delivered for use.

The product is set in parameters for shipment.
If it is combined with a different product parameter, failure can result.

2 General Instructions (continued)

 Check the product for the following points before operation.

• Damage to electric driving line and signal lines.

• Looseness of the connector to each power line and signal line.

• Looseness of the actuator/cylinder and driver mounting.

• Abnormal operation.

• Stop function

 When more than one person is performing work, decide on the

procedures, signals, measures and resolution for abnormal
conditions before beginning the work.

 Also designate a person to supervise the work, other than those

performing the work.

 An operation test should be performed at low speed, start the test at

a predefined speed, after confirming there are no problems.

 Actual speed of the product will be changed by the workload.

Before selecting a product, check the catalogue for the instructions
regarding selection and specifications.

 Do not apply a load, impact or resistance in addition to a transferred

load during return to origin.

In the case of the return to origin by pushing force, additional force will
cause displacement of the origin position since it is based on detected
motor torque.

 Do not remove the nameplate.

2.5 Actuator with lock

Warning

 Do not use the lock as a safety lock or a control that requires a

locking force.

The lock used is designed to prevent dropping of work piece.

 For vertical mounting, use the product with a lock.

If the product is not equipped with a lock, the product will move and drop
the work piece when the power is removed.

 "Measures against drops,” means preventing a work piece from

dropping due to its weight when the product operation is stopped
and the power supply is turned off.

 Do not apply an impact load or strong vibration while the lock is

activated.

If an external impact load or strong vibration is applied to the product, the
lock will lose its holding force and damage to the sliding part of the lock or
reduced lifetime can result. The same situation will happen when the
lock slips due to a force higher than its holding force, as this will
accelerate the wear to the lock.

 Do not apply liquid, oil or grease to the lock or its surroundings.

When liquid, oil or grease is applied to the sliding part of the lock, its
holding force will be reduced significantly.

 Take “measures against drops” and check that safety is assured

before mounting, adjustment and inspection of the product.

If the lock is released with the product mounted vertically, a work piece
can drop due to its weight.

2.6 Please refer to the auto switch references in “Best Pneumatics”
when an auto switch is to be used.

2.7 Unpacking

Caution

 Check the received product is as ordered.

If a different product is installed from the one ordered, injury or damage
could result.

4.1 Design and selection

Warning

 Do not apply a load in excess of the actuator specification.

A product should be selected based on the maximum work load and
allowable moment.
If the product is used outside of the operating specification, the eccentric
load applied to the guide will become excessive and have adverse effects
such as creating play in the guide, reduced accuracy and reduced
product life.

 Do not exceed the speed limit of the actuator specification.

Select a suitable actuator by the relationship of allowable work load
and speed.
Noise or reduction of accuracy may occur if the actuator is operated in
excess of its specification and could lead to reduced accuracy and
reduced product file.

 Do not use the product in applications where excessive external

force or impact force is applied to it.

This can lead to premature failure of the product.

4.2 Handling

Caution

 Do not operate by fixing the piston rod and moving the actuator

body.

An excessive load will be applied to the piston rod, leading to damage to
the actuator and reduced lifetime.

 Do not operate by fixing the piston rod and moving the actuator

body.

An excessive load will be applied to the piston rod, leading to damage to
the actuator and reduced lifetime.

4.3 Mounting

Caution

 When mounting the product, use screws with adequate length and
