Precautions for use
This chapter covers restrictions and requirements the user should consider when using the product.
General
z
Be sure to use our cable to connect the actuator and the driver.
In the following cases, purchase our cable separately. Check on the Oriental Motor Website for the model name.
•
If a flexible cable is to be used.
•
If a cable of 3 m (9.8 ft.) or longer is to be used.
•
If a motor and driver package without a cable was purchased.
•
If an actuator only was purchased.
z
When conducting the insulation resistance measurement or 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.
z
Do not make an impact on the actuator.
Do not drop the actuator. Also, do not hit the motor or gear-reduction mechanism on something hard. Doing so may
cause the positioning accuracy decrease, the motor section damage or the product service life reduction.
z
Make sure not to hit or apply a strong impact on the encoder (ABZO sensor).
•
Making a strong impact on an encoder (ABZO sensor) may cause the motor malfunction or damage to the encoder
(ABZO sensor).
•
When transporting the actuator or installing a load, handle the actuator carefully not to make a strong impact on
the moving part.
•
The warning label shown in the figure is indicated on the motor part of the
actuators equipped with the
AZ
Series.
Warning label
z
Do not move the encoder (ABZO sensor) toward a strong magnetic field.
A magnetic sensor is built into the encoder (ABZO sensor). If the motor is installed close to equipment which
generates a strong magnetic field, the encoder (ABZO sensor) may break or malfunction. Especially, the
DGM60
is
easily affected by a magnetic field, so make sure the environment at transportation and storage as well as the
installation location in use. Keep the magnetic flux density on the surface of the encoder (ABZO sensor) so as not to
exceed the values in the table.

ambient temperature is exceeding 20 °C (68 °F) and 40 °C (104 °F) or less.
z
Meshing noise of mechanical sensor
A gear type mechanical sensor is built into the encoder (ABZO sensor). Although the meshing noise of gears may
generate, it is not malfunction.
