6. Electric actuators / Guide rod Slider Common precautions
6.1 Design and selection
Warning
1. 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, 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. And also when “With magnet / switch rail” option is selected,
Auto switch may not detect correctly by the deflection of the guide rod.
2. 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.
3. 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. Do not apply excessive external force or impact force to the motor.
Miss-alignment of the motor may lead to signal detection error, increasing internal friction or damage
to the motor.
5. When external force is applied to the table, it is necessary to add the external force to the
workload as the total carried load for the sizing.
When mounting cable duct and so on in parallel to the actuator, it is necessary to add the friction
to the workload as the total carried load for the sizing too.
6. Because of the guide mechanism type, vibration that comes from an external source may
be introduced into the work-piece during operation.
Do not use this product in a location where vibration is not allowed.
6.2 Handling
Caution
1. INP output signal
1) Positioning operation
When the product comes within the set range by step data [In positon], output signal will be
turned on. Set to [1] or higher for LEL.
2. Do not change the positioning force from initial setting.
If the positioning force is changed, it may cause a decrease in performance.
3. Do not operate by fixing the table and moving the actuator 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.
4. This actuator cannot be used for vertically mounted applications.
5. Check the specification for the minimum speed of each actuator.
6. 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.
