SAFETY
The e-Rodless Actuator and this manual contain essential information for the protection of users
and others from possible injury and property damage and to ensure correct handling.
Please check that you fully understand the definition of the following messages (signs) before
going on to read the text, and always follow the instructions.
Please read the operation manuals of related apparatus and understand it before operating the
actuator.
Read this manual and follow its instructions. Signal words such as WARNING, CAUTION and
NOTE, will be followed by important safety information that must be carefully reviewed.
IMPORTANT MESSAGES
Indicates a potentially hazardous situation which could result in death
or serious injury if you do not follow instructions.
Gives you helpful information.
Indicates a potentially hazardous situation which if not avoided, may
result in minor injury or moderate injury.
Do not use the product in the environment with possible presence of flammable,
explosive or corrosive gas with the product to prevent fire, explosion or corrosion.
Note the actuator doesn't have explosion proof construction.
During operation, do not enter your hand into moving range nor touch moving parts.
It may cause injury.
Do not disassemble, remodel (including change of printed circuit board) or repair.
An injury or failure can result.
Do not operate beyond specification range.
Fire, malfunction or switch damage can result.
Please use it after confirming the specification.
Do not perform operation and setting by a wet hand.
Electric shock may occur.
The grounding should be performed separately at short length near controller if pos-
sible.
Be sure to ground the product to keep the capability of resistance for the noise in the actuator.
Ground with FG terminal.
Perform functional inspection after maintenance.
Stop operation when equipment or component doesn't work properly. Safety may not be guaran-
teed by unintended malfunction.
Ensure the safety in wiring for ALM signal by inputting emergency stop signal and causing succes-
sive error.
Do not touch the side and lower part of motor and controller.
These parts become hot and should not be touched until it is confirmed they become cool enough.
Do not connect driving power supply and turn on it before the area where the work
(slider) is moved confirms safety.
The movement of the work may cause accident. And when power supply is turned on, the work is
returned to home position by input IN1 or IN2 signal. (Except that stroke learning is not performed
at all.)
After the stroke is adjusted, turn on power supply and then perform stroke learning.
If the stroke leaning is not performed, the product may not operate along with the adjusted stroke
and damage the connected equipment.

SAFETY (continue)
NOTE
Follow the instructions given below when handling your actuator. Otherwise, the switch may be
damaged or may fail, thereby resulting in malfunction.
• Do not use at voltage over specified voltage.
•Do not apply the load over max.
•Keep the space for maintenance.
•Do not drop and collide the product or give excessive impact to it.
•Hold the body for handling.
•Keep tightening torque.
•Do not install the actuator to the place used as foot base for work.
•Keep flatness of mounting face for actuator within 0.1/500mm.
•Do not give repeated bending and tensile force to the connected cable to prevent the breakage of
the cable.
•Connect wiring properly.
•Do not energize the product during wiring.
•Do not use in the place with dust, particle and splash of water, chemicals and oil to prevent
breakage and malfunction of the product.
•Do not use in the place creating magnetic field to prevent the malfunction of the actuator.
•Do not use in the environment subject to temperature cycle.
•Do not use where close to surge generating source.
•Do not short the load. Short of the load of the controller is indicated as error, but it may cause
over current and break the actuator.
•Do not push setting buttons with the pointed staff to avoid the damage of the buttons.
•Perform maintenance for the product periodically.

1.Stroke adjustment
Adjust the stroke of actuating part.
Stroke adjusting unit
Fixing (2 pcs)
Lock nut for adjusting bolt
Adjusting bolt
1-1 Loosen fixing bolt, move the unit to the position where required stroke is obtained and
fix the unit by the bolt.
1-2 Loosen lock nut for adjusting bolt for fine setting of stroke by the bolt. After the fine
adjustment, tighten the lock nut again to fix the stroke.
After the stroke is adjusted, turn on power supply and then perform stroke learning.
If the stroke learning is not performed, the product may not operate alongwith the adjusted
stroke and damage the connected equipment.
Setting (continue)
Apply DC24V to power supply for signal and drive.
If leaning of stroke is not completed, 3 indicator lamps,
MOTOR, END and MIDDLE blink. If the stroke learning is
completed, with receipt of drive command, the product
starts return to original position (movement to motor
side or end side).
•Intermediate stop command does not perform return
to origin.
•If necessary, re-application of power supply should be
done when 5s or more passes after PWR indicator
lamp goes off.
2.Application of power supply
3.Stroke learning
3-1 By push of over 3s at least, the product comes
into learning mode and starts stroke learning.
3-2 Confirm 2 indicator lamps MOTOR and END are
blinking.
Since the actuator starts moving automatically to learn
the adjusted stroke, do not put any objection such as
tool and work around the actuator. 3-3 After stroke
learning is completed, the actuator stops at motor side
and MOTOR indicator lamp lights on.
•It is noted to put neither the tool nor work, etc. on
surroundings of the actuator.
4.Setting of intermediate position
Note) After pressing , the indicator lamp of MID-
DLE, MOTOR, and END blink for max. 3s.
4-2 By push of over 1s at least again during light-
ing of MIDDLE indicator lamp (See page 8 for
indicator lamp of intermediate 1 to 3), setting
mode for intermediate position is achieved.
4-3 Confirm the MIDDLE indicator lamp is flashing.
4-4 Select setting method between direct teaching
setting and JOG teaching setting. Initially, inter-
mediate position is set to the point on half of
adjusted stroke.
4-4-1 Direct teaching setting Move slider manual-
ly during setting.
4-4-2 JOG teaching setting Move slider by push
of or of controller during setting.
4-5 After the intermediate position is fixed, push over 1s to return the actuator to normal
operation.
5.Trial operation
Push , and to check the operation adjusted in the above processes.
(See operation method of 4-1 for the travel to intermediate stop)
4-1 Slider is moved to the specified intermediate position with following method.
When intermediate position is not set, position 1 to 3 are all set at the center of the stroke.
During operation, do not enter your hand into moving range nor touch moving parts.
It may cause injury.
