14.3 Handling
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. 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
electric actuator while in
operation.
5. When installing, adjusting, inspecting or performing maintenance on the product, driver 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 driver 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 driver and product combined as delivered for use.
The product parameters are set before shipment. If the driver is combined with a different
electric actuator, 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 driver/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 the "Return to Origin"
operation.
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. An operation test should be carried out using a low speed. Start operation using the predefined
speed after confirming there is no problems.
[Ground]
Warning
1. Please give the earth of the
electric actuator.
2. Please make it to the earth of the exclusive use. The earth construction is D seed.
(Below earth resistance 100Ω)
