8. Cantilever
When the actuator is operated at high speeds while it is fixed at one end and free at the other end
(flange type, foot type, double clevis type, direct mount type), a bending moment may act on the
actuator due to vibration generated at the stroke end, which can damage the actuator. In such a
case, install a support bracket to suppress the vibration of the actuator body or reduce the speed so
that the actuator does not vibrate. Use a support bracket also when moving the actuator body or
when a long stroke actuator is mounted horizontally and fixed at one end.
9. When mounting the actuator or attaching to the work piece, do not apply strong impact or
large moment.
If an external force above the allowable moment is applied, it may cause looseness in the guide unit,
an increase in sliding resistance or other problems.
10. Ensure sufficient space for maintenance activities.
When installing the products, allow access for maintenance.
13.3. 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 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” 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. For the controller, set parameters which are appropriate to the connected actuators.
Operation with inappropriate parameters may cause failure of the controller or actuator, or damage
to the user's systems.
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.
