Precautions for use
▌8
4 Precautions for use
This section covers limitations and requirements the user should consider when using the
product.
zGeneral
•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 eld. A magnetic
sensor is built into the encoder (ABZO sensor). If the actuator is installed close to
equipment which generates a strong magnetic eld, the encoder (ABZO sensor) may
break or malfunction. Keep the magnetic ux density on the surface of the encoder (ABZO
sensor) so as not to exceed the values in the table.
Magnetic ux 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.

9 ▌
Precautions for use
zTemperature
•In order to protect the encoder (ABZO sensor), use the actuator so that the surface
temperature on the motor case does not exceed 80 °C (176 °F). If the surface temperature
on the motor case may exceed 80 °C (176 °F), improve the operating conditions such
as ambient temperature, operating speed, duty cycle and others. If the encoder (ABZO
sensor) temperature reaches the upper limit, the motor overheat protection alarm will
generate.
zOperation
•Operate an actuator in the range of the operating ambient temperature. If the actuator is
operated outside the operating ambient temperature, the viscosity of grease may change,
causing the thrust force to decrease.
•Keep 20 m (65.6 ft.) or less for the wiring distance between the actuator and driver.
Exceeding 20 m (65.6 ft.) may cause the thrust force to decrease.
•The holding torque is decreased by the current cutback function of the driver when the
actuator stops. When selecting the actuator, make sure the holding torque at standstill by
checking the catalog specication.
•Do not use the electromagnetic brake as a safety brake. To use the electromagnetic brake
to hold the load in position, do so after the actuator operation is stopped.
•Do not use the electromagnetic brake as a means to decelerate and stop the actuator.
The brake hub of the electromagnetic brake will wear signicantly and the braking force
will drop. Since the power o activated type electromagnetic brake is equipped, it helps
maintain the position of the load when the power is cut o, but this brake cannot securely
hold the load in place.
•Do not press the ball screw shaft against a load at the speed exceeding the maximum
push speed or the maximum push-motion return-to-home speed. The mechanical impact
may cause damage to the actuator. If the ball screw shaft was pressed at high speed, take
measures by referring to "10 Troubleshooting and remedial action" on p.31.
zInspection
•Grease on the ball screw shaft may darken within a short time after the start of operation.
Refer to "8 Maintenance" on p.27, and wipe o the dirty grease to apply new grease.
•If an abnormal noise (i.e., from deection or interference) is generated while operating the
non-guide type actuator, the installation accuracy may have dropped. Stop the operation
and check the installation accuracy of the ball screw shaft.
