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 f orce higher than its holding f orce, as this w ill
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 s afety is assured
befor e 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.

4 Installation
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.
Avoid using the electric actuator in a way that rotational torque
would be applied to the piston rod.
If rotational torque is applied to the piston rod the non-rotating guide will
become damaged or deformed and non-rotational accuracy will be
reduced. (Refer to the allowable rotational torque table below)

To attach / screw a bracket or nut to the end of the piston rod.
The piston rod should be fully retracted.
Hold the piston rod by the square across flats end with a spanner or
other means to prevent the piston rod from rotating.
Ensure that the bracket, screw or nut is installed correctly and tightened
to the specified torque value given in this document.

4.3 Mounting
Caution
When mounting the product, use screws with adequate length and
tighten them to the recommended torque.
Tightening w ith larger torque than the specified range may cause malfunction while the tightening with smaller torque can allow the
displacement of actuator position. In extreme conditions the actuator
could become detached from it’s mounting position.
