Design/selection
DANGER
Do not use this product in areas containing
combustible, inflammable, explosive, or other
dangerous substances.
Doing so may cause the product to ignite, catch fire, or explode.
Ensure that the product is not exposed to water or
oil droplets. Doing so may lead to fire or failure.
When mounting the product, be sure to securely hold
and fix it (including the workpiece). If the product tips
over, falls, or malfunctions, personnel may be injured.
Be sure to use a stable DC power supply (24 VDC
±10%) for the motor power supply, control power
supply, and the input-output circuit power supply.
Direct connections to an AC power supply may lead
to fire, rupture, or damage.
WARNING
When performing an emergency stop, it may take
several seconds until the machine stops depending
on the movement speed and the equipped load.
Design a safety circuit or device to avoid equipment damage
and human injury when the machine stops due to system
abnormality such as an emergency stop or power outage.
Set up a safety fence to prevent anyone from
entering the movable range of the electric actuator.
In addition, install the emergency stop button
switch as a device in a location which is easy to
operate in an emergency situation.
Configure and wire the emergency stop button so
that it does not automatically reset or cannot be
carelessly reset by personnel.
Use a shaft that is equipped with a brake when the
shaft body is not horizontally mounted.
There is a risk that the actuator may fall and cause
injury when the servo (including emergency machine
stops and alarms) and brake are turned off.
The brake on a brake-equipped shaft is not able to
completely hold the actuator in every situation. The
brake alone cannot reliably hold the actuator in
cases where safety must be guaranteed such as
when performing maintenance in an application
where the slider moves with an unbalanced load or
when stopping the machine for a long period of
time. Be sure to place it in a balanced state or
apply a mechanical locking mechanism.
Install the product in an indoor location with low humidity.
Installing the product in a location where it is exposed to
rain water or high humidity (85% humidity or above, with
condensation) may lead to short circuits or fire accidents.
Oil droplets and oil mist are also strictly prohibited.
Follow the precautions regarding the temperatures for usage
and storage to use and store the product without condensation.
Failure to do so may lead to malfunctions and shorten the
product lifetime. Provide ventilation if heat builds up.
Do not install the product near locations where it is exposed to
direct sunlight, dust, and heating elements as well as corrosive
gas, explosive gas, flammable gas, or combustible materials. In
addition, this product was not designed for chemical resistance.
Exposure to chemicals may lead to failure, explosion, or ignition.
Do not use or install the product in a location where it is exposed
to strong electromagnetic waves, ultraviolet light, or radiation.
Doing so may lead to malfunction or failure.
CAUTION
To avoid adding inductive noise when wiring the
product, do not wire it in a location where it is
exposed to large currents or strong magnetic fields,
and do not use the same piping and wiring (multi-
conductor cables, etc.) as large-scale motor power
lines. Also exercise caution near the inverter power
supplies and wiring sections (the same wiring and
piping cannot be used) used in robots and other
equipment. Be sure to frame ground the power
supply and insert a filter in the output section.
If the product's output section is shared with an
inductive load and power supply that can cause a
surge such as a solenoid valve or relay, the surge
current may wrap around the output section and
cause damage, so separate the product's output
power supply from any outputs which may create an
inductive load. If a separate power supply cannot be
used, connect a surge absorption element directly in
parallel with all inductive loads.
Select a power supply which provides excess capacity
based on the number of installed products.
Malfunction may occur if there is no excess capacity.
(Rough estimate: 42...3.0 A/unit, 56...4.3 A/unit)
Do not disassemble the products.
The fixed cable cannot be used in applications where
it is repeatedly bent. Use a movable cable in places
where it is repeatedly bent.
Fix the movable cable so that it does not easily move.
In addition, do not bend the cable at sharp angles (bend
radius of 68 mm or less) when fixing the position.
When turning on the power supply, it may recognize an
unintended position as the origin position when an
external stopper or holding mechanism (brake, etc.) are
attached to recognize the origin position. Exercise caution
regarding the placement of the external stopper or other
mechanism so that the origin can be properly detected
after the power supply is turned on.
The customer is responsible for confirming the
compatibility of CKD products with the customer's
systems, machines and equipment.
