- Drives built to specifications, such as dust proof, can be used In the specified Mounting environments. However, concerning the connector to the machine used, implement measures based on the Mounting environment.
- Mount In a location that enables easy operation, such as inspection and maintenance.
- Mount on a sufficiently rigid base.

4-2 Mounting Angle
There is no limit on a mounting angle.
However, do not use Outdoor type and For a motor with ESB brake in a direction other than the ordered mounting direction.
For the gearmotor, the mounting angle differs depending on the specification of a drive, therefore, see the maintenance manual foreach model.
Do not remove the motor’s eye-bolt. In the rare case that it is removed, insert a bolt or other appropriate material into the screw
hole to prevent water or other substances from entering the motor through the screw hole.

95. Coupling with Other Machines
CAUTION- Confirm 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 output shaft;otherwise the key could fly off, 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 specified limits. When the unit is directly coupled with another machine, check that the direct coupling accuracy is within
the specified 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 ofdamage to the products.

5-1 Checking Rotational Direction- If the wiring is carried out as indicated in P15 to 43, the motor shaft will rotate clockwise as seen from the anti-load side when the product is destined for South Korea, and will rotate counterclockwise when the product is destined for another country.
- To cause reverse rotation of a 3-phase power source motor, reverse L1 and L3 or R and T in the connection diagram.
- For a gearmotor, the rotation direction of a gearmotor output shaft may differ from that of a motor shaft, and see the maintenancemanual of each model.

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, orthe collar could come off.
- Shrinkage fit is recommend.

(1) When Using a Coupling
The alignment accuracy (A, B, X) in figure 5-1 should be no greater than that shown in Table 5-1.

Note: S ee the maintenance manual for each gearmotor for thealignment accuracy.

Figure 5-1(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 the motor. (See Figure 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 Figure 5-3)
- When using multiple V-belts, use a matched set having the same circumferential length.

DANGER- Do not handle the unit when power is turned on. Be sure to turn off the power when operating on the unit; 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 fire may result.
- Do not forcibly bend, pull, or clamp the power cable and lead wires; otherwise, electric shock or fire may result.
- Correctly ground the grounding bolt; otherwise, electric shock may result.

CAUTION- When wiring, follow the facility's regulations and electrical codes; otherwise, burning, electric shock, injury, and fire may
result.
- The motor is not equipped with a protection device. However, it is compulsory to install an overload protector according tofacility electrical codes. It is recommended to install other protective devices (earth leakage circuit breaker, etc.), in addition
to an overload protector, in order to prevent burning, electric shock, injury, and fire.
- Do not touch the terminals when measuring insulation resistance; otherwise, electric shock may result.
- When using a star-delta starter select one with an electromagnetic switch on the primary side (3-contact point type); otherwise, fire may result.
-Voltage PWM inverters that use I GBT 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 filter, AC reactor, etc. between the inverter and motor to inhibit the surge voltage.
-  For motor with brake , do not turn on connection power to the brake coil when the motor is stopped. Otherwise coil burnout fire may result. Also, mistaken wiring could damage the rectifier.
- If ambient temperature exceeds 60°C, place the rectifier in a location where the temperature is 60°C or less. In this case, always protect the entire rectifier with a cover. However, standard ambient temperature conditions for units with and without
brakes is -10 to +40°C. (Manufacturing with a special specification is required for operation in an environment where ambient
temperature exceeds 40°C.)- Long cables cause large voltage drops. Select cables with appropriate diameter so that the voltage drop will be no greaterthan 2%.
- After wiring outdoor types , check that terminal box mounting bolts are not loose, and correctly attach the terminal box
cover.

6-1 Measuring Insulation Resistance
When measuring insulation resistance, always disconnect the control panel 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 below.
Table 6-1 Values for Insulation ResistanceMotor Voltage

Low insulation resistance is a sign that there is an insulation failure. Do not apply power. Consult an accredited service station.

6-2 Coordination of System Protection- Use a wiring breaker for short circuit proofing.
- Use an overload protection device designed to handle currents that exceed the rated current on the nameplate.

6-3 Connecting the Power Cable.

In the case of a motor voltage of 400V class, the brake is 200V class, so when using inverter drive, connect the brake to a 200V classpower supply by using a separate turnoff circuit.
Be careful not to connect the brake to a 400V class power supply, because this will result in the brake burning out.
- For brake types, see Table 1-2 on P6 or Table 7-3 on P46.
- The motor must be insulated to inverter-drive a 400V class 3-phase motor.
- Brake action delay time is different between normal and quick-braking circuits.
Table 7-3 on P46 shows action delay time. Choose the circuit that matches work requirements.
- Use a quick-braking circuit to improve hoisting equipment and stopping precision.
- Use a quick braking circuit when a phase-advancing capacitor is mounted.
- For information on electromagnetic contactors and varistors for quick-braking circuits, see Table 6-4 on P44.

6-7 Points to Note when Using a Quick Braking Circuit
When using brakes with quick braking circuits, take note of the following items.
- Connect a varistor (protection element) to protect the quick braking circuit contact points from surge voltage generated by the brakeaction.
- Wire the quick braking circuit contact points to the brake power source secondary side contacts. Contact points might not be protected.
- For information on using an alternating current electromagnetic contactor for contact points for quick braking circuits, see Table 6-4.
If multiple contact points are required, note the following issues.
- Connect electromagnetic contactor contact points in serial. (See Figure 6-2)
- Connect the varistor (VR) as close to the unit as possible. (See Figure 6-2)

- This recommended contactor nomenclature is for Fuji Electric FA Components & Systems Co., Ltd. and Mitsubishi Electric Corporation
contactors. Products from other manufacturers are also allowable If they have equivalent capabilities.
- Recommended contactor contact point capacity indicates the case where durability regarding electronic opening and closing (servicelife) is approximately 2 million times (for FB-30, ESB-250, approximately 1 million times).
- Of the recommended contactors, the Mitsubishi Electric Corporation S-N11 has one auxiliary contact point; the S-N18 has none. Thisapplies if, for inverter drive or other reasons, two or more auxiliary contact points are required. (Other connectors in Table 6-4 have two
or more auxiliary contact points.)- This recommended varistor nomenclature is for Nippon Chemi-Con Corporation varistors. Products from other manufacturers are also
allowable if they have equivalent capabilities.
- In the FB-20, 30, ESB250 and 250-2, a varistor for protecting the connector contact points is built in to the rectifier.

In particular, brake torque may not be at the prescribed level for initial operation, and after a long period of inactivity. In sucha case, turn the brake on and off under as light load as possible to contact the brake’s friction surfaces.

8-1 Daily Inspection and Maintenance
Make certain to carry out daily inspection in accordance with Table 8-1. Neglecting inspections is a source of trouble.
Table 8-1 Daily Inspection
Inspection item

Inspection detail

Current ValueIs the current no greater than the rated value shown on the nameplate?

Noise

Are there unusual noises, or are there extreme changes in the noises?

Vibration
Surface Temperature

Is there abnormally large vibration? Are there extreme changes?
Is surface temperature unusually high? Is it extremely rising?

Mounting Bolts

Are the mounting bolts loose?

Chain, V-Belt

Are the chain or V-belt loose?

- F or a motor with the capacity of 90W or less and an ALTAX NEO traction drive (a model with letter "R" or “S" attached to the end of theframe size), the current value of the motor may stay high temporarily due to increased viscosity of grease for the gear unit and motor
bearing grease during cold winter.										There are no concerns of burnout of a motor even if the current may exceed the rated current for 5 to 15 minutes in a no load operation.													Considerations may be needed for the current value setting of an overload protection device, including an electronic thermal relay andfor selection of an inverter capacity range.										Please consult with us for details.											If any problems are found in a daily inspection, follow "9. Troubleshooting" (on P86 and 87) to take appropriate actions. If these actions
do not remedy the issue, immediately contact the nearest authorized service station.

Avoid using grease other than that listed in Table 8-4.

(4) Procedures for Filling and Discharging Grease for Open Bearings
See the constructions in Figure 8-1.
[1] R emove the discharge port plug, and discharge the old grease. While the machine is running, replenish with new grease through thegrease fitting.
(Grease change will be incomplete if replenishing is done while the machine is stopped.)[2] Run the machine for approximately 10 minutes after the grease is inserted. Then fasten the discharge port plug.

- Overfilling could cause the bearing to overheat, grease to leak and other problems. Be careful.
- Do not think that it is allowable to replenish with a large quantity to extend the replenishment interval.
- Please maintain the machine properly. Neglecting replenishment when resuming operation, or periodic replenishment when themachine is operating could lead to abnormal wear, bearing noise, bearing burnout, and other problems.

8-3 Oil Seal Maintenance- An oil seal has a finite life. If it is used for a long period, the performance of the seal will be degraded due to natural deterioration or
wear. The life of a seal differs greatly according to the conditions under which it is used and also the surrounding environment. When the
product is used under normal conditions (operation for 10 hours a day under a uniform load, at normal temperature), we recommendthat you replace the seals every one to three years. If an oil seal or the sliding surface of the V-ring becomes worn or rusty, replace it.
The sliding surface of an oil seal is made of carbon steel, so in order to prevent rust forming on it, if there are parts of the oil seal that are
exposed to the outside, periodically take steps to prevent rusting by coating the oil seal with rust preventive oil.

8. Daily Inspection and Maintenance
8-4 Brake Maintenance and Inspection
DANGER- Do not handle the unit when power is turned on. Be sure to turn off the power when operating on the unit; otherwise, electric shock
may result.
- When using for lifting, do not release the brake while a load is suspended; otherwise it could fall, causing an accident.
- Do not operate the machine while the brake is released by the manual brake release bolt; otherwise, falling, going out of control, or
damage to the equipment may result.
- Before operation turn power on and off to check brake action; otherwise falling or running out of control could occur.
- Do not bring water or oils in contact with the brake. Brake torque degradation could cause falling or running out of control.

CAUTION- After gap inspection and adjustment do not operate with the fan cover removed; otherwise loose clothing may be caught in theserotating parts and cause serious injury or death.
- Changing brake linings requires experience. Consult with the nearest authorized service station.

Given normal operation conditions, brake mechanical lifetime is quite long at 2 million times (1 million times for FB-30, ESB-250
and ESB-250-2). These conditions include the moment of inertia for the load being no greater than the moment of inertia for thebrakemotor. However, please periodically inspect the brake gap (G). The brake lining wears after long hours of running time, making it impossible for the brake to release. When 2 million times is exceeded (1 million times for FB-30, ESB-250 and ESB-250-2), wear
and damage to mechanical parts may cause dropping or overdrive problems.

8-5 Brake Construction and Gap Inspection and Adjustment- The brake is spring activated (power-off type).
- The brake lining wears after long hours of operating the brake, making it impossible for the brake to release. Therefore please periodically inspect the brake gap (G).
- If the gap is close to the limit on inspection, adjust the gap.
- In some brakes, a shock absorber is inserted between the stationary core and the armature plate to reduce the noise that results fromthe braking action.
When inspecting be careful that the gap gauge, other measuring tool or anything else does not damage the shock absorber or cause
it to fall out.
There is danger that if the shock absorber is damaged or falls out, brake noise will increase and the brake will not function properly.

ESB-250-2- Brake torque may not be at the prescribed level during initial operation. In such a case, turn the brake on and off under as light load
as possible to contact the brake’s friction surfaces.
- When changing the brake lining, replace the boss and leaf springs (for FB-5B, FB-8B, FB-10B1, FB-15B1, FB-5E – 15E, 20, 30, the gap
adjusting nuts are included) as a set.
- After 2 million or more cycles of operation, (for FB-30, ESB-250 and ESB-250-2, 1 million or more cycles of operation), or after 10 years
or more have passed since shipment from the factory, inspect to check whether continued operation is possible, even if the lining is
not at the usable thickness limit.
- Check the following items concerning the condition of each mechanical part.
Are the linings split or chipped?
Is there any peeling or gap between the lining and the disc?
Does the brake lining or the spline of the inner disc exhibit cracking, chipping, or stepped wear?
Is there any stepped wear on the surfaces around the stud bolts or armature plate?
- Change the brake lining, even if it has not reached the usable thickness limit, in case that the brake is used outdoors or in a highhumidity environment or that 10 or more years has passed because of long period storage or rest.

8-7 Changing the V-Ring and Waterproof Seal (Outdoor Type)V-rings and waterproof seals degrade over the years, losing their waterproofing abilities. As a guideline contact the nearest authorized service station every 3 years. If the sliding surfaces of oil seals or V-rings show signs of wear or corrosion, replace them with new
ones. Sliding surfaces are made of carbon steel, so rain water, condensation and other factors could cause rust to form and spread.
Because this could lead to oil seal damage, take on-going rust prevention measures.

with a hexagonal wrench to release the brake. Be careful not to over rotate the brake release bolts. (Rotate the brake release bolts
while checking to see if the brake is released.) (See Figures 8 -36, 8-37)(2) A fter releasing the brake, to return it to its original condition, for safety, return the manual release prevention spacers that were
removed in (1) to their original positions. (See Figure 8-37)

n FB-20, FB-30(1) I n the case of outdoor types, remove the lid on the window part of the outdoor cover [33]. Remove the grommet [28] (indoor type),
remove the brake release bolt [2] using a hexagonal wrench (for an M8 hole bolt), and remove the rubber gasket [3] and the manual
release prevention spacer [4]. The brake will release when you again rotate the bolt using the hexagonal wrench. Be careful not toover rotate the brake release bolt. (Rotate the brake release bolt [2] while checking to see if the brake is released.) (See Figure 8-38)(2) A fter releasing the brake, to return it to its original condition, for safety, return the manual release prevention spacer and the rubber
gasket [3] that were removed in (1) to their original positions, and firmly tighten the brake release bolt [2]. (See Figure 8-39)
Next re-attach the grommet [28] (indoor type) in its original state. In the case of outdoor types, attach the lid on the window part ofthe outdoor cover [33] as it was before.
- Note that if the rubber gasket [3] and the seal washer [5] for the brake release bolt [2] unit are not attached when returning tothe original state, dust-proofing and waterproofing capabilities will be lost.
Also, firmly tighten the brake release bolt [2]. Otherwise waterproofing capability may be lost.
Also make certain to return the grommet [28] (indoor type) or outdoor cover [33] window lid (outdoor type) to their originalstates.
- If the machine is operated when the brake release bolt has not been returned to its original position, in the worst case it is possible that the manual release would function before maximum gap is obtained, and the brake would cease to function. Therefore, make certain to always operate with the manual release prevention spacer attached.

All you need to do to release the brake is push the release lever over. (See Figure 8-43)(1) To release the brake, pull the release lever out of the holder, and push it toward the load or anti-load side.
(Some specifications do not allow pushing the release lever toward the load side.)Be careful not to push the lever too far. Pushing the lever too far could damage the brake.
(Push the release lever while checking to see if the brake is released.)(2) When operating the motor, make certain to return the lever to its original position and set it inside the holder. Start operation after
confirming that the brake operates properly.
Note: While the lever is held down, the brake remains released. When the lever is released, the brake is applied.
