4. Installation
Common
DANGER
- Do not use a standard unit in an explosive atmosphere (which is likely to be lled with explosive gas or steam). Under
such conditions, an explosion proof motor should be used; otherwise, electric shock, personal injury, explosion re, or
damage to the equipment may result.
- In the case of a Explosion proof motor , use a motor that has specications that are appropriate for a dangerous location
(a location where gas or volatile vapor is present); otherwise explosion, ignition, electric shock, injury, re, or equipment
damage may result.
- Since the inverter itself is not explosion proof, when a ameproof motor is driven by an inverter install an inverter in a place
free from explosive gas; otherwise, electric shock, personal injury, explosion re, or damage to the equipment may result.
CAUTION
- Do not use the products for purposes other than those shown on the nameplate or in the manufacturing specications;
otherwise, electric shock, personal injury, or damage to the equipment may result.
- Do not place ammable objects around the gearmotor; otherwise, re may result.
- Do not place any object around the gearmotor or reducer that will hinder ventilation. Insucient ventilation can cause
excessive heat build-up that may result in burns or re.
- Do not step on or hang from the gearmotor or reducer; otherwise injury may result.
- Do not touch the shaft end of the gearmotor or reducer, inside keyways, or the edge of the motor cooling fan with
bare hands; otherwise, injury may result.
- When the unit is used in food processing applications, machines for cleanroom and so on, vulnerable to oil
contamination, install an oil pan or other such device to cope with oil leakage due to breakdown or failure; otherwise, oil
leakage may damage products.
- Always drain oil lubricated models before mounting, moving, and transporting. Moving with lubricating oil in the
machine may cause oil to escape from the air vent, etc.

4-4 Flange Type Assembly Issues (Models: CNFM, CHFM, CNF, CHF, etc.)
[1] Remove the fan cover if there is one installed (reducer frame size of 6160 or more).
[2]
Remove the nut and bolt for ring gear housing. Take care when loosening the nut, as the bolt for ring gear housing may rotate together.
[3] A nut of a dierent size to the nut for ring gear housing may be assembled between the nut for ring gear housing and casing when
the device is shipped. Remove this nut, as it is a spacer replacement nut for preventing damage to the faces of the nut for ring gear
housing and casing, as well as for preventing the nut coming free of the threaded section of bolt for ring gear housing.
[4]
Assemble the device to the driven machine, and tighten the nut and bolt for ring gear housing with the tightening torque shown in Table 4.2.
- Disassembly prevention nuts are installed at 2 locations of the bolt for ring gear housing (opposing angles) to prevent disassembly
of the reducer in case the bolt for ring gear housing is removed. Do not remove the disassembly prevention nuts. Removing them
may result in the casing, ring gear housing, internal cover, motor and other parts disassembling and falling o, and may cause injury.
- Using only the disassembly prevention nuts with the nut for ring gear housing removed does not generate a sucient level of
torque. Do not use only the disassembly prevention nuts for ring gear housing for long periods of time, move them excessively or
subject them to shock. Lubricant or grease may leak if there gaps develop between any of the mating faces.
- Tightening the nut for ring gear housing changes the axial force of the disassembly prevention nuts, and may result in them coming
loose. To remove the CYCLO Drive after temporarily assembling the device to the driven machine, check that the disassembly
prevention nuts have not become loose.

4-5 Keyless Shaft Motor Assembly Issues (Hollow Connection High Speed Shaft for Servo Motors)
[1] Remove oil, dirt, and other contaminants from the motor shaft and inside of the CYCLO Drive high speed shaft. (The inner surface of
the high speed shaft is treated with rust prevention oil before shipping.)
[2] Position the reducer on a platform so that the slow speed shaft is on the bottom.
[3] Align the high speed shaft with the notch on the clamp ring.
[4] Remove the adapter plate cap and insert a hexagonal wrench through the setting hole into the hexagon socket head bolt in the
clamp ring. Next, insert the motor shaft into the high speed shaft.
[5] When assembling the motor and CYCLO Drive, make sure that the centers of both shafts are aligned. Do not force the assembly if the
shafts are slanted or misaligned.
[6] Fasten the motor and adapter plate using the motor mounting bolt. Tighten after conrming that the motor tting is securely
inserted into the adapter plate tting. Important: If the bolt is tightened when the tting is not inserted, uneven tightening will
result, causing damage to the internal bearing and other components.
[7] Tighten the clamp ring hexagon socket head bolt to the torque shown in Table 4-3.
[8] After operating at low speed, increase the tightening torque as shown in Table 4-3.
[9] Attach the adapter plate cap that had been removed.

4-6 Keyed Shaft Motor Assembly Issues (Hollow Connection High Speed Shaft for Servo Motor or
General Flange Motors)
[1] Remove oil, dirt, and other contaminants from the motor shaft and inside of the CYCLO Drive high speed shaft. (The inner surface of
the high speed shaft is treated with rust prevention oil before shipping.)
[2] Align the motor shaft key with the high speed hollow shaft keyway. (Keyway dimensions conform to JIS B 1301-1996 (ISO)“Keys and
Their Corresponding Keyways: Parallel keys (Normal Type)”).
[3] Coat the motor shaft with molybdenum disulde grease to prevent fretting.
[4] Depending on the motor combination, a spacer for preventing the key from falling out may be in a separate shipment. Before
assembly, insert the spacer deep into the hole in the high speed shaft. Operation with uninserted spacer could result in the key
falling out and damaging the shaft.
[5] When assembling the motor and CYCLO Drive, make sure that the centers of both shafts are aligned. Do not force the assembly if the
shafts are slanted or misaligned or if the key is only partially engaged.
[6] Fasten the motor and adapter plate (internal cover) using the motor mounting bolt. Tighten after conrming that the motor tting
is securely inserted into the adapter plate (internal cover) tting. Important: If the bolt is tightened when the tting is not inserted,
uneven tightening will result, causing damage to the internal bearing and other components.

5. Coupling with Other Machines Common
12
CAUTION
- Conrm the rotation direction before coupling the unit with the driven machine. Incorrect rotation direction may
cause personal injury or damage to the equipment.
- When operating the product alone (uncoupled), remove the key that is temporarily attached to the slow speed shaft;
otherwise the key could y o, and injury may result.
- Cover rotating parts; otherwise, injury may result.
- When coupling the product with a load, check that the centering, the belt tension and parallelism of
the pulleys are within the specied limits. When the unit is directly coupled with another machine, check that the
direct coupling accuracy is within the specied limits. When a belt is used for coupling the unit with another machine,
check the belt tension. Correctly tighten bolts on the pulley and coupling before operation; otherwise there is a risk of
injury due to scattering the broken pieces or of damage to the products.
5-1 Checking Rotational Direction
(1) For gearmotor
Table 5-1 shows the direction of slow speed shaft rotation when wiring is performed as on P18–31.
Table 5-1 Slow Speed Shaft Rotation Direction (Gearmotor)
When wiring is performed as shown on P18–31, the motor shaft rotates to the right as seen from
the anti-load side.

Common
5-2 Mounting Connected Equipment
- When mounting connected equipment, do not apply impact or excessive axial load to the shaft. The bearing could be damaged, or
the collar could come o.
- Shrinkage t is recommend.
(1) When using a coupling
The alignment accuracy (A, B, X) in gure 5-1 should be no greater than that shown in Table 5-3.
(2) When using chains, sprockets, or gears
- When using a chain, attach so that the chain tension angle is perpendicular to the shaft.
- Refer to the chain catalog or other reference for chain tension.
- The pitch circle of the sprocket and gear shall be more than three times of the shaft diameter.
- The working load point of the sprocket or gear should go from the center of the shaft to this product. (See gure 5-2)
(3) When using a V belt
- Over-tightening the V belt will damage the shaft and bearing. Refer to the V belt catalog or other reference for V belt tension.
- The parallelism, eccentricity β of the two pulleys should be within 20´. (See gure 5-3)
- When using multiple V belts, use a matched set having the same circumferential length.

6. Wiring
14
When using a vector motor, or other manufacturer’s motor (There are some models made by other manufacture.), follow the opera-
tion manual for that motor.
This manual shows wiring for motors with Japanese standard specications. Please consult with us for motors with overseas
specications.
DANGER
- Do not handle the unit when cables are live. Be sure to turn o the power; otherwise, electric shock may result.
- Connect a power cable to the unit according to the diagram shown inside the terminal box or in the maintenance
manual; otherwise, electric shock or re may result.
- Do not forcibly bend, pull, or clamp the power cable and lead wires; otherwise, electric shock or re may result.
- Correctly ground the grounding bolt; otherwise, electric shock may result.
- The lead-in condition of an explosion proof motor shall conform to the facility's electrical codes, extension regulations
and explosion proong guide, as well as the maintenance manual; otherwise, electric shock, personal injury, explosion,
re or damage to the equipment may result.
CAUTION
- When wiring, follow the facility's electrical codes and extension regulations; otherwise, burning, electric shock,
injury, or re may result.
- The motor is not equipped with a protection device. However, it is compulsory to install an overload protector according
to facility electrical codes. It is recommended to install other protective devices (earth leakage breaker,
etc.), in addition to an overload protector, in order to prevent burning, electric shock, injury, and re.
- Never touch the terminals when measuring insulation resistance; otherwise, electric shock may result.
- When using a When using a star-delta starter select one with an electromagnetic switch on the primary side (3-contact
point type); otherwise, re may result.
- Voltage PWM inverters that use IGBT generate high-voltage surges at the motor terminals, which may degrade the
insulation on the motor windings. Especially such as when the cable is long in the 400V class, a surge voltage over 1300V
occurs. Therefore, in this case, install an LCR lter, AC reactor, etc. between the inverter and motor to inhibit the surge
voltage.
- When using a motor with brake , do not turn on connection power to the brake coil when the motor is stopped.
Otherwise coil burnout re, may result. Also, mistaken wiring could damage the rectier.
- When a explosion proof motor is driven by an inverter , use one inverter for one motor. Use the approved inverter for the
motor.
- When measuring the insulation resistance of a explosion proof motor , conrm that there is no gas or explosive vapor in
the vicinity, in order to prevent possible explosion or ignition.
- If ambient temperature exceeds 60℃, place the rectier in a location where the temperature is 60℃or less. In this case,
always protect the entire rectier with a cover. However, standard ambient temperature conditions for units with and
without brakes is −10 to 40℃. (Manufacture to special specication is required for operation in an environment where
ambient temperature exceeds 40℃.)
- Long cables cause large voltage drops. Select cables with appropriate diameter so that the voltage drop will no greater
than 2%.
- After wiring outdoor types and explosion proof types , check that terminal box mounting bolts are not loose, and
correctly attach the terminal box cover.

Figure 6-1
6-2 Measuring Insulation Resistance
When measuring insulation resistance, always disconnect the control board and measure the motor alone.
Measure insulation resistance before wiring. Insulation resistance (R) is changed by a number of factors, including motor output,
voltage, type of insulation, winding temperature, moisture, degree of fouling, time used, and amount of time test voltage is applied.
However, normally, it must be above the values in Table 6-1.
Table 6-1 Values for Insulation Resistance
Motor voltage Megaohmmeter voltage Insulation resistance (R)
Low-voltage electric motors of
no more than 600V 500V Minimum 1 M
Reference: JEC -2100 contains the following equation.
Rated Voltage (V) + (RPM/3)
R ≧+ 0.5 (M)
Rated output power (kW) + 2,000
Rated Voltage (V)
R ≧(M)
Rated output power (kW) + 1,000
Low insulation resistance is a sign that there is an insulation failure. Do not apply power. Consult an accredited service station.
6-3 Coordination of System Protection
- Use a wiring breaker for short circuit proong.
- Use an overload protection device designed to handle currents that exceed the rated current on the nameplate.
- For Increased safety, explosion proof motor , use an overload protection device capable of protecting the locked rotor current on the
nameplate within the allowable locking time.
