3 Precautions for use
This section covers restrictions and requirements the user should consider when using the product.
Wiring
zConnecting a motor and a driver
The dedicated connection cable (sold separately) is required since a 60 W motor is the connector type. (p.13)
Use the dedicated connection cable (sold separately) when extending the wiring distance between the motor and the
driver.
zNotes when the cable is used
Note the following points when the cable is used.
How to x the cable
Fix the cable at the positions near the connector so that no stress due to the bending or self-weight of the cable is
applied on the connector.
Also, do not excessively bend the cable near the connection part of the connector. Applying stress on the cable may
cause poor contact or disconnection, leading to malfunction or heat generation.

.
Connector
Banding band, etc.
Fix using two cable ties or a wide clamp. When the cable is moved, it causes the connectors to
move, causing stress to apply on the connector part.
When bending the cable
Do not excessively bend the cable.
Applying stress on the cable may cause poor contact or disconnection, leading to
malfunction or heat generation.
Do not bend ex
cessively
Installation
zGrease measures
On rare occasions, grease may ooze out from the gearhead. If there is concern over possible environmental
contamination resulting from the leakage of grease, check for grease stains during regular inspections. Alternatively,
install an oil pan or other device to prevent damage resulting from contamination. Grease leakage may lead to
problems in the user’s equipment or products.
zWhen using in low temperature environment
When an ambient temperature is low, a load torque may increase due to the oil seal or viscosity increment of grease
used in the gearhead, and the output torque may decrease or the overload alarm may be generated. However, as time
passes, the oil seal or grease is warmed up, and the motor can be operated without generating the overload alarm.

Precautions for use
7
zApply grease to the hollow output shaft of a hollow shaft at gearhead.
When using a hollow shaft at gearhead, apply grease (molybdenum disulde grease, etc.) on the surface of the load
shaft and inner walls of the hollow output shaft to prevent seizure.
Insulation resistance measurement and dielectric strength test
zDo not conduct the insulation resistance measurement or the dielectric strength test with the motor
and driver connected.
Conducting the insulation resistance measurement or dielectric strength test with the motor and driver connected
may result in damage to the product.
Operations
zUse an electromagnetic brake motor in an application of vertical drive such as elevating equipment.
When the motor is used in an application of vertical drive such as elevating equipment (lifting and lowering device),
use an electromagnetic brake motor so that the load can be held in position.
zThe electromagnetic brake of the motor is used for holding the motor shaft.
Actuating the electromagnetic brake to hold the motor shaft while the motor is rotating may result in damage to
equipment.
zRotation direction of the gearhead output shaft
Pinion shaft type/parallel shaft gearhead, CS geared motor
The rotation direction of the gearhead output shaft may vary with that of the motor output shaft depending on the
gear ratio of the gearhead.

5-3 Installing a load
Pinion shaft type/parallel shaft gearhead, CS geared motor, round shaft type
When installing a load on the motor or the gearhead, pay attention to the following points.
•Align the center axis of the motor output shaft or the gearhead output shaft with that of the load.
•A key slot is provided on the output shaft for the combination type-parallel shaft gearhead and the CS geared
motor. Form a key slot on the load side and secure the load using the parallel key.
•When coupling the motor or the gearhead with a load, pay attention to centering, belt tension, parallelism of
pulleys, etc. Also, rmly secure the tightening screws of the coupling or pulleys.
•When installing a load, do not damage the motor output shaft (gearhead output shaft) or bearings. Installing
the load forcibly with a hammer or the like may break the bearings. Do not apply any excessive force to the
output shaft.
•Do not modify or machine the output shaft of the motor or gearhead. This may damage the bearing, resulting
in damage to the motor or gearhead.
When using the output shaft end tapped hole of a gearhead
Use a tapped hole provided at the end of the output shaft as an auxiliary
means for preventing the transfer mechanism from disengaging. Fixed scre

Pinion shaft type/hollow shaft at gearhead
If a large impact occurs at instantaneous stop or a large radial load is applied, use a stepped load shaft.
•Apply grease (molybdenum disulde grease, etc.) on the surface of the load shaft and inner walls of the hollow
output shaft to prevent seizure.
•When installing a load, do not damage the output shaft or the bearings. Installing the load forcibly with a
hammer or the like may break the bearings. Do not apply any excessive force to the output shaft.
•Do not modify or machine the output shaft.
This may damage the bearing, resulting in damage to the motor and gearhead.
