:Indicates "prohibited" actions that must not be performed.
:Indicates "compulsory" actions that must be performed.
WARNING
Do not use the product in explosive or corrosive environments, in the
presence of ammable gases, locations subjected to splashing water, or
near combustibles. Doing so may result in re, electric shock or injury.
Do not transport, install the product, perform connections or inspections
when the power is on. Always turn the power o before carrying out these
operations. Failure to do so may result in electric shock or equipment damage.
Do not use the electromagnetic brake of the motor as a safety brake.
Take safety measures other than the electromagnetic brake. Failure
to do so may result in injury or damage to equipment.
Use an electromagnetic brake motor in an application of vertical drive
such as elevating equipment. If a motor without an electromagnetic
brake is used, the moving part may drop. This may result in injury or
damage to equipment.
Do not machine or modify the connection cable. Doing so may result
in electric shock or re.
Do not forcibly bend, pull or pinch the cables. Doing so may result in
re and electric shock.
Do not touch the motor or speed controller when conducting
insulation resistance measurement or dielectric strength test.
Accidental contact may result in electric shock.
Do not disassemble or modify the motor and gearhead. This may cause
electric shock or injury.
Only qualied and educated personnel should be allowed to perform
installation, connection, operation and inspection/troubleshooting of the
product. Handling by unqualied and uneducated personnel may result
in re, electric shock, injury or equipment damage.
The motor is Class І equipment. When installing the motor, ground the
Protective Earth Terminal of the motor. Failure to do so may result in
electric shock.
Keep the input power voltage within the specied range. Failure to do so
may result in re or electric shock.
WARNING
Use a motor, gearhead and speed controller only in the specied
combination. An incorrect combination may cause in re, electric shock
or equipment damage.
Always turn o the power before performing maintenance/inspection.
Failure to do so may result in electric shock.
CAUTION
Do not use the motor, gearhead beyond its specications. Doing so
may result in electric shock, injury or damage to equipment.
Do not touch the motor, gearhead during operation or immediately
after stopping. The surface is hot and may cause a skin burn(s).
Keep the area around the motor free of combustible materials. Failure
to do so may result in re or a skin burn(s).
Do not leave anything around the motor that would obstruct
ventilation. Doing so may result in damage to equipment.
Do not carry the product by holding the motor, gearhead output
shaft or any of the cables. Doing so may result in injury.
Do not touch the motor output shaft (tip or pinion) with bare hands.
Doing so may result in injury.
When assembling the motor (pinion shaft) with the gearhead,
exercise caution not to pinch your ngers or other parts of your body
between the motor and gearhead. Injury may result.
When installing the motor, gearhead in the equipment, exercise
caution not to pinch your ngers or other parts of your body
between the equipment and motor or gearhead. Injury may result.
Do not touch the rotating part (output shaft) while operating the
motor. Doing so may result in injury.
When an abnormality is noted, turn o the power immediately. Failure to
do so may result in re, electrical shock or injury.
Securely install the motor, gearhead to their respective mounting
plates. Inappropriate installation may cause the motor, gearhead to
detach and fall, resulting in injury or equipment damage.
Provide a cover on the rotating part (output shaft). Failure to do so
may result in injury.
Securely install the load on the motor and gearhead output shaft.
Inappropriate installation may result in injury.
Be sure to ground the motor and speed controller to prevent them
from being damaged by static electricity. Failure to do so may result in
re or damage to equipment.
The motor surface temperature may exceed 70 °C (158 °F)
even under normal operating conditions. If the operator
is allowed to approach a running motor, attach a warning
label as shown in the gure in a conspicuous position.
Failure to do so may result in skin burn(s).

Precautions for use
This section covers limitations and requirements the user should consider when
using the product.
zBe sure to match the output power and power supply voltage
when combining a motor and speed controller
zConnecting the motor and speed controller
Use a connection cable (sold separately) when extending the wiring distance
between the motor and the speed controller.
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.
zCaution when using under low temperature environment
When an ambient temperature is low, since the load torque may increase by the
viscosity increment of the oil seal or grease, the motor starting may take a long time
or the motor rotation speed may fall. However, if the operation is continued for a
while, the oil seal or grease will be warmed up, and the motor can be driven at the
normal rotation speed.

Removing/Installing the gearhead
See the following steps to replace the gearhead or to change the outlet position of
the lead wires and the position of the terminal box.
zRemoving the gearhead from the motor
Remove the hexagonal socket head screws (2 pieces)
assembling the motor and gearhead and detach the
motor from the gearhead.

zInstalling the gearhead to the motor
Keep the pilot sections of the motor and
gearhead in parallel, and assemble the
gearhead with the motor while slowly
rotating it clockwise/counterclockwise.
At this time, note so that the pinion of the
motor output shaft does not hit the ange
or gears of the gearhead strongly. Pinion of

Assemble the gearhead to the motor
in a condition where the motor output

Do not forcibly assemble the motor and gearhead. Also, prevent metal
objects or foreign substances from entering in the gearhead. The
pinion of the motor output shaft or gear may be damaged, resulting
in noise or shorter service life.
Do not allow dust to attach to the pilot sections of the motor and
gearhead. Also, assemble the motor and gearhead carefully by not
pinching the O-ring at the motor pilot section. If the O-ring is crushed
or severed, grease may leak from the gearhead.

zMotor with cooling fan
When installing a motor with cooling fan onto a device, leave 10 mm (0.39 in.) or more
behind the fan cover or open a ventilation hole so that the cooling inlet on the back
of the motor cover is not blocked.
 Installing a load
The gearhead shaft is provided with a key slot
for connecting the transmission parts. When
connecting the transmission parts, ensure that
the shaft and parts have a clearance t, and
always x the parallel key to the output shaft
with a screw to prevent the parts from rattling
or spinning.

Momentary excess torque based on EN 60034-1
Model Momentary
excess torque Momentary excess torque represents a
maximum torque that can maintain the
operation for 15 seconds without stalling
or abrupt speed change even if the torque
is increased gently while operating at rated
voltage and rated frequency.
SCM315, SCM560 120% of the
rated torque
