Precautions for use
This section covers limitations and requirements the user should consider when using the
product.
z
General
•
Always use an accessory cable to connect the actuator and driver.
•
Be sure to provide an anti-spin mechanism for the non-guide type actuator. The actuator
cannot be operated without the anti-spin mechanism because the ball screw rotates idly.
•
Do not remove the set collar attached to the ball screw shaft. Doing so may result in
damage to ball screw shaft.
•
Do not remove the joint of the guide type actuator from the ball screw shaft. Doing so
may deteriorate the installation accuracy of the ball screw shaft, resulting in malfunction
or shorter service life of the actuator. In addition, if the joint is removed, the home position
which has been set in the encoder (ABZO sensor) at the time of shipment may deviate. This
may cause unexpected movements of the actuator, leading to damage to equipment.
•
When conducting the insulation resistance measurement and the dielectric strength test,
be sure to separate the connection between the actuator and the driver. Conducting the
insulation resistance measurement or dielectric strength test with the actuator and driver
connected may result in damage to the product.
•
Do not drop the actuator, and do not hit the motor and mechanism sections against other
objects. Doing so may cause the positioning accuracy decrease, the motor section damage
or the product service life reduction.
•
Do not make a strong impact on the encoder (ABZO
sensor). Making a strong impact on an encoder (ABZO
sensor) may cause the actuator malfunction or damage
to the encoder (ABZO sensor). The warning label shown
in the right is attached on the motor.
•
Do not move the encoder (ABZO sensor) toward a strong magnetic field. A magnetic
sensor is built into the encoder (ABZO sensor). If the actuator is installed close to
equipment which generates a strong magnetic field, the encoder (ABZO sensor) may
break or malfunction. Keep the magnetic flux density on the surface of the encoder (ABZO
sensor) so as not to exceed the values in the table.
Magnetic flux density
When operating
10 mT
When transporting and storing
10 mT
•
A gear type mechanical sensor is built into the encoder (ABZO sensor). Although the
meshing noise of gears may generate, it is not malfunction.
•
When you install a carrier guide for load transportation, use the non-guide type actuator.
Using the guide type actuator may cause unconformity between guides, leading to
damage to equipment.
•
When transporting the actuator or installing a load, handle it carefully not to make a
strong impact on the moving part.
