Abnormal noises or vibrations may mean that the product is not properly mounted, and if allowed to
continue in this state, damage to the equipment may occur.
4. Never touch the rotating parts of the motor while in operation.
5. Before installing, adjusting, inspecting, or performing maintenance on the product, controller,
and related equip- ment, be sure to shut off the power supply. 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 an actuator that has a servo motor (24 VDC), the motor phase detection step is
conducted by inputting the servo’s on signal just after the controller power is turned on. The
motor phase detection step moves the table/rod the dis- tance of the one screw-lead as the
maximum.
(The motor rotates in the reverse direction if the table/rod hits an ob- stacle such as the end stop
damper.) Take the motor phase detection step into consideration when installing and operating this
actuator.
Caution
1. Keep the controller and the actuator combined as delivered for use.
The actuator’s parameters are set at the time of shipment. If it is combined with a different set of
parameters, failure can result.
2. Conduct the following inspection before operation.
a) Confirm that the power supply line and each signal line is not damaged.
b) Confirm that the power supply line and each signal line is not loosened.
c) Confirm that the electric actuator/cylinder/controller/driver is not mounted loosely.
d) Confirm that the electric actuator/cylinder/controller/driver is operating correctly.
e) Confirm the function of the emergency stop of the whole system.
3. If several persons are to be working conjointly, determine the pro- cedure, signs, measures
against abnormality, and restarting mea- sures in advance. Then, have someone else,
supervise the work.
4. The product may operate at a speed different from the set speed depending on the load and
resistance.
When selecting a product, check the catalog for instructions regarding selection and specifications.
5. Do not apply a load, impact, or resistance in addition to the transferred load during the return
to origin.
If the product is made to return to origin by pushing force, a displacement of the origin position may
occur.
6. Do not remove the name plate.
7. Operation tests should be done at a low speed. Start operation by predefined speed after
confirming there are no problems.
8. Do not apply forces of impact, collision, or resistance to the moving parts of an actuator in
operation.
Doing so will cause a decrease in product life, damage to the product, etc.
【
Grounding
】
Warning
1. Be certain to ground the actuator.
2. Dedicated grounding should be used.
Grounding should be to a D-class ground. (Ground resistance of 100 or less.)
3. Grounding should be performed near the actuator to shorten the grounding distance.
