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. 90°C to
100°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 mo ving part of the
actuator while in operation.
There is a serious risk of injury.
• When installing, adjusting, inspecting or performing maintenance
on the product, controller 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 i mplement
measures such as a safety plug.
• In the case of the actuator that has a servo motor (24 VDC), the
“motor phase detection step" is done by inputting the servo on
signal just after the controller power is turned on.
The “motor phase detection step” operates the table/rod to the
maximum distance of the lead screw. (The motor rotates in the
reverse direction if the table hits an obstacle such as the end stop
damper.) Take the “motor phase detection step” into consideration
for the installation and operation of this actuator
2 General Instructions (continued)
Caution
• Keep the controller and product combined as deli vered for use.
The product is set in parameters for shipment.
If it is combined with a different product parameter, failure can result.
• 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 controller/driver mounting.
• Abnormal operation.
• Stop function
• When more than one person is performing work, decide on the
procedures, signals, measures and resol ution for abnormal
conditions before beginning the work.
• Also designate a person to s upervise 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 w orkload.
Before selecting a product, check the catalogue for the instructions
regarding selection and specifications.
• Do not appl y a load, impact or resist ance 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 for the product with a lock 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 i mpact 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 surroundin gs.
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

4 Installation
4.1 Design and selection
Warning
• Do not apply a load in excess of the actuator specific ation.
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 s pecification.
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 life.
• 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.
Caution
• Do not operate by fixing the table and moving the actuat or body.
An excessive load will be applied to the table, which could lead to
damage to the actuator and reduced accuracy and reduced product life.
• Belt drive actuator cannot be used for vertically mounted
applications.
•••• In the case of the belt driven actuator, vibration may occur during
operation at speeds within the actuator specification, this could be
caused by the operating conditions. Change the speed setting to a
speed that does not cause vibration.
4 Installation (continued)
4.2 Mounting
Caution
• Keep the flatness of mounting surface to within 0.1 mm or l ess.
Insufficient flatness of the work piece or the surface onto which the
actuator body is to be mounted can cause play in the guide and
increased sliding resistance.
• When mounting the workpiece or other device to the actuator
tighten the fixing screws with adequate torque within the specified
torque range.
Tightening the screws with a higher torque than the maximum may
cause malfunction, whilst tightening with a lower torque can cause the
displacement of the mounting position or in extreme conditions
detaching of the work piece.
Use screws with adequate length, but with length less than the
maximum thread depth.
The use of screws that are to long can touch the body and cause
malfunction.
• When m ounting the actuator, use screws with adequate length and
tighten them with adequate torque and use all of the mounting
holes to maintain the catalogue performance.
Tightening the screws with a higher torque than recommended may
cause malfunction, whilst the tightening with lower torque can cause the
displacement of mounting position or in extreme conditions the actuator
could become detached from its mounting position.
• When mounting the actuator, le ave a gap of 40 mm or more to allow
for bending of the actuator cable.
