3. 3 Attaching Load
■BH6G2-, BH6G2-RA
Screw
The 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.
When connecting the transmission parts, ensure that the shaft and parts
haveaclearancet,andsecurewithascrewtopreventthepartsfrom
wobbling.
Note Do not use excessive force, or hammer the transmission parts onto
the gearmotor shaft as damage may occur.
When using the output axis tip screw hole of a gearhead
Useascrewhole[M6,e󰀨ectivedepth12mm(0.47in.)]providedatthetipof
the output shaft of the gearhead as an auxiliary means for preventing the
transfer mechanism from disengaging.

Note ・Do not apply excessive force when inserting the load shaft into the
gearhead. Excessive or abrupt force may damage the gearhead
internal bearings.
• When the hollow-shaft gearhead or solid-shaft gearhead with a low
  gearratio(5,6,7.5,or9)iscombinedwithasingle-phasemotor,
  noise(resonascesound)mayoccurduringoperationundernoor
light load. This noise can be reduced by adding a frictional load.
3. 4 Disassembling the motor and gearhead (For only combination types)
Motor-gearhead assembly screws
(2-M4 hexagonal socket-head screws)
∗Illustration shows parallel shaft type.
In combination types, motor and gearhead are attached by means of
motor-gearheadassemblyscrews(hexagonalsocketheadscrews).
These screws must be removed in order to replace the gearhead.
Once the gearhead has been replaced, reassemble the unit using the screws
included with the gearhead for this purpose.
To install the unit in machinery, use the mounting screws, and follow the
instructions given in section 3. 1 ~ 3. 3. The screw tightening torque for
assembling motor and gearhead is shown in the below chart.

Note Wiringcannotbesimpliedforverticaldriveapplicationsorthree-phase
motors.
Connectioncanbesimpliedbyusingtheconnectingdiagramsshownbelow
whenchangingtheswichRUN/STOPofthemotorandtheelectromagnetic
brake by one swich. Using the connection shown below, however, results in a
120msec increase in braking time over that of the basic connection with a
corresponding increase in overrun. The reason for this is that an
electromagnetic energy of motor electromagnetic brake, so that the
electromagnetic continues to operate for about 120msec even though the swich
SW1hasbeenturnedo󰀨.Thebrakethustakeslongertoengage.
4. 3 Operation
Note • This motor is B type insulation motor.
Make sure that the motor case temperature does not exceed 90°C(194°F)duringmotoroperation.
Operating the motor above 90°C(194°F)willshortenthelifeofthecoilandtheballbearings.
Motor case temperature can be measured by fastening a thermometer to the motorʼs surface, or with thermo-tape.
• Bring motors to a complete stop before switching the direction of rotation.
If you try to switch the direction of rotation before the motor has stopped, it may not change or may require time.
This may damage the motor.
• Use the provided capacitor for single-phase motors and always keep the capacitor connected after the motor is started.
• Refer to the capacitor connection method on page 5.

■Starting and stopping
SW1 operates motor and electromagnetic brake action.
MotorwillrotatewhenSW1isswitchedsimultaneouslytoON(shortcircuit).WhenSW1isswichedsimultaneouslytoOFF(open),themotor
stops immediately by electromagnetic brake and holds the load.
Note When operating the electromagnetic brake, this may make a friction noise because this is the braking system by friction, but this is not a
problem.
■Other ways of operating
Note When driving a vertical load, this method cannot be applied because this may cause the load to fall.
・Hastening the motor's starting time
If the electromagnetic brake is left release, the motor can be started much faster.
Optimum timing for release of the brake is at least 10msec before starting up the motor.
・Releasing Electromagnetic brake
 Ifyouwishtoreleasethebrakewhilethemotorisstopped,applyvoltagebetweenonlytwoterminalsformagneticbrake(B).
The electromagnetic brake is released and the motor shaft can be rotated easily by hand.

6. Maintenance · inspection
6. 1 Inspection
It is recommended that periodic inspections would be conducted for the items listed below after each operation of the motor. If an abnormal condition
isnoted,discontinueanyuseandcontactyournearestOrientalMotorsaleso󰀩ce.
■Inspection item
• Check if any of the mounting screws of the motor and gearhead are loose.
•Checkifthebearingpart(ballbearings)ofthemotorgeneratesunusualnoises.
•Checkifthebearingpart(ballbearings)orgearmeshingpartofthegearheadgeneratesunusualnoises.
• Check if the output shaft of the motor and gearhead and a load shaft are out of alignment.
6. 2 Warranty
Check on the Oriental Motor Website for the product warranty.
6. 3 Disposal
Dispose the product correctly in accordance with laws and regulations, or instructions of local governments.
7. Locked rotor burnout protection of motor
This motor is equipped with a feature listed below to prevent the motor from burning out as a result of abnormal heating which may be caused by
misapplication.
■Thermal protection (“THERMALLY PROTECTED”“TP212”is stamped on the motor name plate)
When the motor reaches a predetermined temperature, the internal thermal protector is activated and the motor is stopped.
In this stage, the electromagnetic brake is left released so that the motor does not keep hold of the load. Adopt another safety measure.
With the automatic resume feature, the motor automatically begins operating again as soon as the motor temperature falls.
Alwaysturnthepowero󰀨beforeperforminginspections.
Thermal protector activation range:Poweristurnedo󰀨at150°C±5°C(302°F±9°F)
 Poweristurnedbackonat96°C±15°C(205°F±27°F)
8. Troubleshooting
When the motor is not functioning normally, perform an inspection covering the points listed in the table bellow.
If the inspection shows that everything is normal but the motor and control unit still are not functioning correctly, contact the nearest
ORIENTALMOTORo󰀩ce.
Problem Things to check
The motor does not rotate
or
motor rotates at low speed
1.Is the correct voltage being supplied to the motor?
2.Areleadwiresproperlyandrmlyconnected?
3.Is the load too large?
4.If lead wires have been extended by using a terminal strip or terminal block, are the lead wires
 properlyandrmlyconnectedatallpoints?
