Warning label
Precautions for use
This section covers restrictions and requirements the user should consider
when using the product.
•Be sure to use the accessory cable to connect the motor and
driver.
•When conducting the insulation resistance measurement or
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 the product.
•Make sure not to hit or apply a strong impact on the motor
output shaft or the encoder (ABZO sensor).
Applying a strong impact on the
motor output shaft or the encoder
(ABZO sensor) may cause encoder
(ABZO sensor) damage or motor
malfunction. The warning label shown
in the right is attached on the motor. Warning label
•Do 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. Especially, since the motors
of frame size 20 mm (0.79 in.) and 28 mm (1.10 in.) are easily aected by a
magnetic eld, so make sure the environment at transportation and storage
as well as the installation location in use.
Keep the magnetic ux density on the surface of the encoder (ABZO sensor)
so as not to exceed the values in the table.
Motor frame size
Magnetic ux density
When transporting
and storing When operating
28 mm (1.10 in.) or less 5 mT 2 mT *
42 mm (1.65 in.) or more 10 mT 10 mT
* When the magnetic ux density is exceeding 1 mT and 2 mT or less, use in an
environment where the operating ambient temperature is exceeding 20 °C
(68 °F) and 40 °C (104 °F) or less.
•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.
•Do not apply a radial load and axial load in excess of the
specied permissible limit
Operating the motor under an excessive radial load or axial load may damage
the motor bearings (ball bearings). Be sure to operate the motor within the
specied permissible limit of radial load and axial load.
•Use the motor in conditions where its surface temperature will
not exceed 80 °C (176 °F).
The surface temperature on the motor case may exceed 80 °C (176 °F)
depending on operating conditions such as ambient temperature, operating
speed, duty cycle, and others. In order to protect the encoder (ABZO sensor),
use the motor so that the surface temperature on the motor case does not
exceed 80 °C (176 °F). If the encoder (ABZO sensor) temperature reaches the
upper limit, the motor overheat protection alarm will generate.
Use the geared motor in a condition where the gear case temperature does
not exceed 70 °C (158 °F), in order to prevent deterioration of grease and
parts in the gear case.
•Holding torque at standstill
The motor holding torque is reduced by the current cutback function of the
driver at motor standstill. When selecting a motor, check the holding torque
at motor standstill in the specications on the catalog.
•Do not use the electromagnetic brake to reduce speed or as a
safety brake.
Do not use the electromagnetic brake as a means to decelerate and stop the
motor. The brake hub of the electromagnetic brake will wear significantly
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 motor
has stopped.
•Preventing electrical noise
For measures with regard to noise, refer to the OPERATING MANUAL Driver.
•Make sure to provide measures so that the key is not own o
when operating the motor with key in a state where a load is not
installed.
Flying o the key may result in injury or damage to equipment.
•Grease of encoder (ABZO sensor) and geared motor
On rare occasions, a small amount of grease may ooze out from the following
places.
yEncoder (ABZO sensor) mechanical part [motors of frame size 20 mm
(0.79 in.) and 28 mm (1.10 in.)]
yGeared motor
If there is concern over possible environmental damage resulting from
the leakage of grease, check for grease stains during regular inspections.
Alternatively, install an oil pan or other device to prevent leakage from
causing further damage. Oil leakage may lead to problems in the customer's
equipment or products.
•Peak torque of geared motor
Always operate the geared motor under a load not exceeding the peak
torque. If the load exceeds the peak torque, the gear will be damaged.
•Rotation direction of the gear output shaft
The relationship between the rotation direction of the motor shaft and that
of the gear output shaft changes as follows, depending on the gear type and
gear ratio.
Type of gear Gear ratio Rotation direction (relative to the
motor rotation direction)
TS geared 3.6, 7.2, 10 Same direction
20, 30 Opposite direction
FC geared, PS geared,
HPG geared All gear ratios Same direction
Harmonic geared All gear ratios Opposite direction

•Do not perform push-motion operation with geared motor.
Doing so may cause damage to the motor or gear part.
Notes when the connection cable is used
Note the following points when an accessory cable is used.
•When inserting the connector
Hold the connector main body, and
insert it in straight securely.
Inserting the connector in a inclined
state may result in damage to terminals
or a connection failure.
•When 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 wires) may
result in damage to the connector.
•Bending radius of cable
Use the cable in a state where the
bending radius of the cable is more
than six times of the cable diameter.
In the case of the lead wire type, use in a
state where the bending radius is more
than four times of the diameter of the
lead wires.
More than 6 times of
cable diameter
•How 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 a exible cable,
this area is a movable range.

contact the metal plate or screws used for installing the motor.
zWhen a coupling or a pulley is installed
When installing a coupling or pulley on the output shaft, do not apply a
strong force to the output shaft. For the standard type motor, in particular, a
mechanical impact may cause damage to the encoder (ABZO sensor).
When installing a coupling or pulley on the standard type motor with a
parallel key, utilize the screw hole on the shaft end.
1. Install a coupling (pulley) on the motor
output shaft.
2. Install a screw, nut, and washer on
the end of the output shaft, and push
the coupling (pulley) and secure with
tightening the screw. Washer

Permissible radial load, permissible axial load and
permissible moment load
Failure due to fatigue may occur when the motor bearings and output
shaft are subject to repeated loading by a radial or axial load that is in
excess of the permissible limit.
The permissible radial load and permissible axial load of the PS geared
type and HPG geared type represent the value that the service life of
the gear part satises 20,000 hours when either of the radial load or
axial load is applied to the gear output shaft.
