(4) Never touch the rotating part of the motor or moving part of the
electric actuator while in
operation.
(5) When installing, adjusting, inspecting or performing maintenance on the product, controller and
related equipment, be sure to shut off the power supply to each of them. Then, lock it so that no
one other than the person working can turn the power on, or implement measures such as a
safety plug.
(6) In the case of the electric actuator that has a servo motor (24
VDC), the “motor phase detection
step” is done by inputting the servo on signal just after the controller power is turned on. The
“motor phase detection step” operates the table/rod to the maximum distance of the lead screw.
(The motor rotates in the reverse direction if the table hits an obstacle such as the end stop
damper.) Take the “motor phase detection step” into consideration for the installation and
operation of this electric actuator.
Caution
(1) Keep the controller and product combined as delivered for use.
The product is set in parameters for shipment. If it is combined with a different parameter, failure can
result.
(2) Check the product for the following points before operation.
a) Damage to electric driving line and signal lines
b) Looseness of the connector to each power line and signal line
c) Looseness of the electric actuator cylinder and controller/driver mounting
d) Abnormal operation
e) Emergency stop of the total system
(3) When more than one person is performing work, decide on the procedures, signals, measures
and resolution for abnormal conditions before beginning the work. Also, designate a person to
supervise work other than those performing work.
(4) Actual speed of the product will be changed by the workload.
Before selecting a product, check the catalog for the instructions regarding selection and specifications.
(5) Do not apply a load, impact or resistance in addition to a transferred load during return to origin.
In the case of the return to origin by pushing force, additional force will cause displacement of the origin
position since it is based on detected motor torque.
(6) Do not remove the name plate.
(7) Operation test should be done by low speed. Start operation by predefined speed after
confirming there is no trouble.
[Ground]
Warning
(1) Be sure to ground the electric actuator.
(2) Grounding should be dedicated ground.
Ground construction is Class D grounding.
(Ground resistance 100 Ω or less)
(3) Make the grounding as close as possible to the electric actuator and shorten the distance to
ground.
[Unpackaging]
Caution
(1) Check the received product is as ordered.
If a different product is installed from the one ordered, injury or damage can result.
