Design/Selection
Warning
1. Use the specified voltage.
If the applied voltage is higher than the specified voltage, mal-
function and damage to the controller may result. If the applied
voltage is lower than the specified voltage, there is a possibility
that the load cannot be moved due to internal voltage drop.
Check the operating voltage prior to start.
2. Do not use the products outside the specifications.
Otherwise, fire, malfunction or damage to the product can re-
sult. Check the specifications prior to use.
3. Install an emergency stop circuit.
Install an emergency stop outside the enclosure in easy reach
to the operator so that the operator can stop the system opera-
tion immediately and intercept the power supply.
4. To prevent danger and damage due to a breakdown
or malfunction of these products, which may occur
at a certain probability, a backup system should be
arranged in advance by using a multiple-layered
structure or by making a fail-safe equipment design,
etc.
5. If there is a risk of fire or personal injury due to ab-
normal heat generation, sparking, smoke generated
by the product, etc., cut off the power supply from
this product and the system immediately.
Caution
1. When using an actuator not horizontally mounted,
an actuator with the lock option is recommended.
Burnout of the internal parts of the controller may occur. If the
actuator is not equipped with a lock, it will move and drop the
workpiece when the power and servo are turned OFF.
Handling
Warning
1. Check the voltage using a tester at least 5 minutes
after power-off when connecting/disconnecting
cables.
Otherwise, electric shock, injury, fire, or serious damage can
result.
2. Do not touch the inside of the controller and its
connector.
Otherwise, electric shock or failure can result.
3. Do not operate or set up this equipment with wet
hands.
Otherwise, electric shock can result.
4. Do not use a product that is damaged or missing
any components.
Electric shock, fire or injury can result.
5. Use only the specified combination between the
electric actuator and controller.
Not doing so may cause damage to the actuator or to the
controller.
Handling
Warning
6. Be careful not to touch, get caught or hit by the
workpiece while the actuator is moving.
An injury can result.
7. Do not connect the power supply or power up the
product until it is confirmed that the workpiece can
be moved safely within the area that can be
reached by the workpiece.
Otherwise, the movement of the workpiece may cause an
accident.
8. Do not touch the product when it is energized and
f o r s o m e t i m e a f t e r t h e p o w e r h a s b e e n
disconnected, as it is very hot.
Otherwise, it may cause burns due to the high temperature.
9. Check the voltage using a tester at least 5 minutes
after power-off when performing installation, wiring
and maintenance.
Otherwise, electric shock, fire or injury can result.
10. Do not use the products in an area where they
could be exposed to dust, metallic powder, ma-
chining chips or splashes of water, oil or chemi-
cals.
Otherwise, a failure or malfunction can result.
11. Do not use the products in a magnetic field.
Otherwise, a malfunction or failure can result.
12. Do not use the products in an environment where
flammable, explosive or corrosive gases, liquids or
other substances are present.
Otherwise, fire, explosion or corrosion can result.
13. Avoid heat radiation from strong heat sources,
such as direct sunlight or a hot furnace.
Otherwise, it will cause a failure to the controller or its
peripheral devices.
14. Do not use the products in an environment with
cyclic temperature changes.
Otherwise, it will cause a failure to the controller or its
peripheral devices.
15. Do not use the products in an environment where
surges are generated.
Devices (solenoid type lifters, high frequency induction fur-
naces, motors, etc.) that generate a large amount of surge
around the product may lead to deterioration or damage to
the internal circuits of the products. Avoid supplies of surge
generation and crossed lines.
16. Do not install the products in a place subject to vi-
bration and impact.
Otherwise, a malfunction or failure can result.
17. If this product is used with a relay or solenoid
valve, use the built-in surge absorbing element
type.
18. This product cannot be used if multiple axes are
fixed to one workpiece.
