17. Electric Actuators/Common Precautions
17.1 Design and selection
Warning
(1) Read the Operation Manual before using the product.
Handling or usage/operation other than that specified in the Operation Manual may lead to breakage
and product failure.
Any damage attributed to use beyond the specifications is not guaranteed.
(2) There is a possibility of dangerous sudden action by the product if sliding parts of machinery
are twisted due to external forces etc.
In such cases, human injury may occur, such as catching hands or feet in the machinery, or damage
to the machinery itself may occur. The machinery should be designed to avoid such dangers.
(3) A protective cover is recommended to minimize the risk of personal injury.
If a driven object and moving parts of the product are in close proximity, personal injury may occur.
Design the system to avoid contact with the human body.
(4) Securely tighten all stationary parts and connected parts so that they will not become loose.
When the product operates with high frequency or is installed where there is a lot of vibration, ensure
that all parts remain secure.
(5) Consider a possible loss of power source.
Take measures to prevent injury and equipment damage in the case of a power supply failure.
(6) Consider the behavior of an emergency stop of the whole system.
Design the system so that human injury and/or damage to machinery and equipment will not be
caused, when it is stopped by a safety device for abnormal conditions such as a power outage or a
manual emergency stop of the whole system.
(7) Consider the action when operation is restarted after an emergency stop or abnormal stop of
the whole system.
Design the system so that human injury or equipment damage will not occur upon restart of operation
of the whole system.
(8) Disassembly and modification is prohibited.
Do not disassemble the product or make any modifications, including additional machining. This may
cause human injury and/or an accident.
(9) Do not use the stop signal, "EMG" of the controller and stop switch on the teaching box as the
emergency stop for the system.
The stop signal, "EMG" of the controller and the stop switch on the teaching box are for decelerating
and stopping the actuator. Design the system with an emergency stop circuit which is applied to the
relevant safety standard separately.
(10) When using for vertical applications, it is necessary to build in a safety device.
The rod may fall due to the weight of the work.
The safety device should not interfere with normal operation of the machine.
Caution
(1) Use the product for the maximum usable stroke.
The product will be damaged if it is used with a stroke exceeding the maximum stroke. Refer to the
specifications of the product.
(2) When the product repeatedly cycles with partial strokes, operate it at a full stroke at least
once a day or every 1,000 strokes.
Otherwise, lubrication can be lost.
(3) Do not use the product in applications where excessive external force or impact force is
applied to it.
The product can be damaged. Components, including the motor, are manufactured to precise
tolerances, so the slight test deformation may cause faulty operation or seizure.
(4) Return to origin cannot be carried out during operating.
This function cannot be carried out during positioning operation or pushing operation.
