Design
①
If the operation involves load fluctuations, ascending/descending movements, or changes in
friction resistance, make sure to provide safety measures.
Failure to provide such measures could accelerate the movement, which may be hazardous to humans,
machinery, and other equipment.
②
If there is a chance that the product will pose a hazard to humans, install a protective cover.
If the moving portion of the product will pose a hazard to humans or will damage machinery or
equipment, provide a construction that prevents direct contact with those areas.
③
Make sure that the secured portions will not loosen.
Be sure to adopt a reliable connecting method if the rotary table is used very frequently or if it is used in
a location that is exposed to a large amount of vibrations.
④
Consider the possibility of a reduction in the circuit air pressure caused by a power failure.
When an actuator is used as clamping mechanism, there is a danger of workpiece dropping if there is a
decrease in clamping force, due to a drop in circuit pressure caused by a power failure. Therefore,
safety equipment should be installed to prevent damage to machinery and bodily injury.
⑤
Consider the possibility of power source related malfunctions that could occur.
For the equipment that rely on power sources such as compressed air, electricity, or hydraulic pressure,
adopt a countermeasure to prevent the equipment from causing a hazard to humans or damage to the
equipment in the event of malfunction.
⑥
Consider the behavior of the rotary actuator in the event of an emergency stop.
Devise a safe system so that if a person engages the emergency stop, or if a safety device is tripped
during a system malfunction such as a power failure, the movement of the rotary actuator will not cause
a hazard to humans or damage the equipment.
⑦
Consider the action of the rotary actuator when restarting after an emergency stop.
Devise a safe design to that the restarting of the rotary actuator will not pose a hazard to humans
or damage the equipment. Install manually controlled equipment for safety when the actuator
has to be reset to the starting position.
⑧
Do not use the product as a shock absorber.
If an abnormal pressure or air leakage occurs, the rotary actuator’s speed reduction capability could
become severely effected, which could pose a hazard to humans and damage the machinery and
equipment.
Selection
①
Confirm the specifications
Rotary actuator is designed only for use in industry compressed air systems.
Do not operate at pressures or temperatures, etc., beyond the range of specifications, as this can
cause damage or malfunction. (Refer to the specifications.)
Please contact SMC when using a fluid other than compressed air.
We do not guarantee against any damage if the product is used outside of the specification range.
②
Select a speed within the product’s allowable energy value.
If the product’s kinetic energy of the load exceeds the allowable value, it could damage the product,
and cause a hazard to humans and damage the machinery and equipment.
