18.3. Handling Precautions
Warning
(1) Do not touch the motor while in operation.
The surface temperature of the motor can increase to approx. 90
o
C to 100
o
C due to operating
conditions. Energizing alone may also cause this temperature increase. Do not touch the motor when
in operation as it may cause burns.
(2) If abnormal heating, smoking or fire, etc., occurs in the product, immediately shut OFF the
power supply.
(3) Immediately stop operation if abnormal operation noise or vibration occurs.
If abnormal operation noise or vibration occurs, the product may have been mounted incorrectly.
Unless operation of the product is stopped for inspection, the product can be seriously damaged.
(4) Never touch the rotating part of the motor or moving part of the actuator while in operation.
(5) When installing, adjusting, inspecting or performing maintenance on the product, controller
and related equipment, shut OFF the power supply to each of them. Then, lock it so that no one
other than the person can turn the power on, or implement measures such as a safety plug.
(6) In the case of the actuator with a servo motor (24VDC), the "motor phase detection step" is done by
turning ON “SVON” just after the controller power is turned ON. The "motor phase detection step"
moves the table/rod for the distance of one screw-lead maximum. (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 actuator.
Caution
(1) Keep the controller and actuator combination as delivered for use.
The product parameters are set before shipment. If the controller is combined with a different
actuator, failure can result.
(2) Check the product for the following points before operation.
a) Damage to power supply line and signal line
b) Looseness of the connector to the power and signal lines
c) Looseness of the actuator/cylinder and controller/driver mounting
d) Abnormal operation
e) Emergency stop of the whole system
(3) When more than one person is performing work, decide on the procedures, signals, measures
for emergency and how to start the operation after the measures taken. 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 the "Return
to Origin" operation.
When performing 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) An operation test should be carried out using a low speed. Start operation using the
predefined speed after confirming there are no problems.
[Grounding]
Warning
(1) Provide a good earth connection to the actuator.
(2) The earth should be a dedicated earth connection. Class D dedicated grounding should be
used. (Ground resistance 100Ω or less)
(3) The earth cable length should be as short as possible.
[Unpacking]
Caution
(1) Check that the received product is as ordered.
If a different product is installed, other than that ordered, injury or damage can result.
