15.3 Handling
Warning
1. Do not touch the motor while in operation.
The surface temperature of the motor can increase to approx. 90oC to 100oC due to operating
conditions. Energizing alone may also cause this temperature increase. As it may cause burns, do
not touch the motor when in operation.
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, 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 actuator that has a servo motor (24VDC), 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 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 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.
[Earth]
Warning
1. Please give the earth of the actuator.
2. Please make it to the earth of the exclusive use. The earth construction is D seed.
(Below earth resistance 100
Ω
)
3. Please shorten the distance until the actuator and earth.
