Attaching load
To shaft of the gearhead has been
machined to an outer diameter
tolerance of h7 and is provided
with a key slot for connecting the
transmission parts. (The
2GN
type has a surface cut by milling.)
When connecting the
transmission parts, ensure that the
shaft and parts have a clearance
fit, and always fix the parallel key
to the output shaft with a screw to
prevent the parts from rattling or
spinning.

Note
Do not use excessive force, or hammer the transmission
parts onto the gearhead shaft as damage may occur.
Mounting the capacitor
Before mounting the supplied capacitor, check that
the capacitor’s capacitance matches that stated on
the motor’s name plate. Mount the capacitor
securely by using M4 screws (not provided).
Ø4.3 mm
(0.169 in.)
Note
•
Do not let the screw fastening torque exceed 1 N·m
(8.8 lb-in) to prevent damage to the mounting foot.
•
Mount capacitor at least 10 cm (3.94 in.) away from the
motor. If it is located closer, the life of the capacitor will
be shortened.
Removing/Installing the gearhead
The gearhead can be removed and the motor lead wire outlet position
changed to a desired 90° direction. The same procedure is followed when
replacing the gearhead.
1.
Remove the hexagonal socket head screws
(2 pcs.) assembling the motor and gearhead,
and detach the motor from the gearhead.

2.
Using the pilot sections of the motor
and gearhead as guides, install the
gearhead to the motor.
At this time, the seal connector
position can be changed to a desired
90° direction.
When installing the gearhead, slowly
rotate it clockwise/counterclockwise
to prevent the pinion of the motor
output shaft from contacting the side
panel or gear of the gearhead.
Also confirm that no gaps remain
between the motor flange surface and
the end face of the gearhead’s pilot
section.

After the motor and gearhead have been assembled, install the
motor/gearhead assembly using mounting screws by referring to the
explanation under “Combination type” on p.2
Note
•
Do not forcibly assemble the motor and gearhead. Also,
do not let metal objects or other foreign matters enter
the gearhead. The pinion or gear of the motor output
shaft may be damaged, resulting in noise or shorter
service life.
•
The hexagonal socket head screws used to assemble
the motor and gearhead together only tentatively secure
the two components. Always use the four supplied
mounting screws when installing the motor/gearhead
assembly.
Connection and operation
Insulate all the wire connections, such as the connection between the motor
and the capacitor connection.
Ground the motor using a Protective Earth Terminal.
For details on connecting the motor and power controller, refer to the
operating manual for Power Controller
TMP-1
.
Note
•
Insulation class of this motor is B. Make sure that the
motor case temperature does not exceed 90 °C (194 °F)
during operation of the motor. Operation exceeding
case temperature 90 °C (194 °F) may significantly
deteriorate the coils and ball bearings of the motor and
shorten the motor’s life span. Motor case temperature
can be measured by fixing a thermometer on the motor
surface. It can also be measured using thermo tape or a
thermocouple.
•
To change rotation direction wait until the motor
completely stops. Otherwise its direction may not
change or may take much time to change.
•
If the motor is be used with AC voltage, connect the
supplied capacitor. Keep the capacitor connected even
after the motor has been started.
Rotating direction of the gearhead output shaft
The rotating direction of the gearhead output shaft may be opposite that of
the motor shaft, depending on the gear ratio. Before performing wiring, be
sure to check the rotating direction of the gearhead output shaft to be used
and determine the desired direction of motor rotation.

Wiring diagram
The connection method will vary depending on the direction.
The direction of motor rotation is as viewed from the side of the motor’s
output shaft. The motor rotates in a clockwise (CW) and counterclockwise
(CCW) direction.

Capacitor connection
The capacitor internal wiring as follows:
Capacitor terminals are internally electrically connection in twos; A-B and
C-D for easy connection. For easy to install terminals use 187 series AMP
FASTON terminals (Tyco Electronics AMP).
Use the supplied capacitor cap to insulate the capacitor terminal connection.
