Precautions for use
7
3 Precautions for use
This chapter covers limitations and requirements the user should consider when using the product.
General
zAlways use the supplied cable or accessory cable to connect the motorized linear slide and driver.
In the following condition, an appropriate accessory cable must be purchased separately.
•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 motorized linear slide and driver package without a cable was purchased.
zWhen conducting the insulation resistance measurement and the dielectric strength test, be sure to
separate the connection between the motor and the driver.
Conducting the insulation resistance measurement or dielectric strength test with the motor and driver connected
may result in damage to equipment.
zDo not make an impact on the motorized linear slide.
Do not drop the motorized linear slide. Also, do not hit the motorized linear slide on something hard. Doing so may
cause the positioning accuracy decrease, the motor damage or the product service life reduction.
zMake 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 motorized linear slide or installing a load, handle the motorized linear slide
carefully not to make a strong impact on the moving part.
•The warning label shown in the right is indicated on the motor of the motorized
linear slide equipped with the AZ Series.
Warning label
zDo not move the encoder (ABZO sensor) toward a strong magnetic eld.
A magnetic sensor is built into the encoder (ABZO sensor). If the motor 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
zMeshing 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.
Temperature
zUse the motorized linear slide equipped with the AZ Series in conditions where the motor surface
temperature will not exceed 80 °C (176 °F).
The motor surface temperature may exceed 80 °C (176 °F) under certain conditions (ambient temperature, operating
speed, duty cycle, etc.). In order to protect the encoder (ABZO sensor), use the motor in conditions where the surface
temperature does not exceed 80 °C (176 °F). If the encoder (ABZO sensor) temperature reaches the upper limit, the
motor overheat alarm will generate.
zUse the motorized linear slide equipped with the AR Series in conditions where the motor surface
temperature will not exceed 100 °C (212 °F).
The motor does not have a function to protect from overheating. The motor surface temperature may exceed 100 °C
(212 °F) under certain conditions (ambient temperature, operating speed, duty cycle, etc.). To prevent the motor
bearings (ball bearings) from reaching its usable life quickly, use the motor in conditions where the surface
temperature does not exceed 100 °C (212 °F).

Precautions for use
8
Operation
zIn the case of the DC power input type products, the maximum speed may not be reached depending
on the ambient temperature or the length of the motor cable.
zHolding torque at standstill
When the motorized linear slide stops, the holding torque will be reduced by the current cutback function of the
driver. When selecting the motorized linear slide, check the holding torque at standstill in the specications on the
catalog.
zDo not use the electromagnetic brake to reduce speed or as a safety brake.
Do not use the electromagnetic brake as means to decelerate and stop the motorized linear slide. 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. Accordingly, do not use the electromagnetic brake as a safety brake. To use the
electromagnetic brake to hold the load in place, do so after the motorized linear slide has stopped.
Notes for when the connection cable is used
Note the following points when a supplied cable or accessory cable is used.
zWhen inserting the connector
Hold the connector main body, and insert it in straight securely.
Inserting the connector in an inclined state may result in
damage to terminals or a connection failure.
zWhen pulling out the connector
Pull out the connector in straight while releasing the lock part
of the connector. Pulling out the connector with holding the
cable (lead wire) may result in damage to the connector.
zBending radius of cable
Use the cable in a state where the bending radius of the cable is
more than 6 times of the cable diameter.
In the case of the lead wire type, use in a state where the
bending radius is more than 4 times of the diameter of the lead
wires. Mo
re than 6 times of cable diameter
zHow to x the cable
Fix the cable at the positions near the connector so as to apply no stress on the connector part.
Take measures so as to apply no stress on the connector by using wide clamps or by xing at two places.
In the case of exible cable,
this area is a movable range.

5-3 Changing the motor cable leading direction
The motor cable leading direction can be changed according to the space of equipment.
•When changing the motor cable leading direction, remove the load, and perform in a state
where the motorized linear slide is placed in a horizontal position. Doing the operation in a
vertical condition may allow the moving part to fall, leading to injury or mechanical
damage.
· If the motor mounting screws are removed in a state where the motorized linear slide is
installed vertically, the motor may rotate rapidly. Thereby, ngers may be caught in the
product or the cable may be disconnected.
•Set the home position again after mounting a motor. If the motorized linear slide is
operated without setting the home position, the moving part may move to unexpected
directions or run at unexpected speeds, leading to injury or mechanical damage.
· The moving part of the motorized linear slide may collide with the mechanical stopper.
· The load may collide with other equipment.
•Be sure to secure the coupling with the specied tightening torque. Unless it is secured
with the specied torque, the ball screw may rotate idly, leading to injury or mechanical
damage.
 When the motorized linear slide is used in a vertical condition, the load may fall.
 When the motorized linear slide is used in a horizontal condition, the moving part of the
motorized linear slide may collide with the mechanical stopper. Also, the load may collide
with other equipment.
