13.3 Precautions for Use
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.
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, 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.
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 nameplate.
(7) Operation test should be done by low speed. Start operation by predefined speed after
confirming there is no trouble.
