When using another manufacturer’s motor, refer to the operation manual for that motor.
(Motors with a motor capacity of 37kW or more are made by other manufacturers. Also, depending on the motor specification, somemotors are made by other manufacturers.)
This manual shows wiring for motors with Japanese standard specifications. Please consult with us for motors with overseas
specifications.

DANGER- Do not handle the unit when cables are energized. Be sure to turn off the power when working 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 the maintenance manual;
otherwise, electric shock or fire may result.
- Do not forcibly bend, pull, clamp or push the power cable and lead wires; otherwise, electric shock or fire may result.
- Correctly ground the grounding terminal; otherwise, electric shock may result.
- For explosion proof motor , the lead-in condition shall conform to the facility’s regulations, electrical codes, and explosion
proofing standard, as well as the maintenance manual. Otherwise, electric shock, personal injury, explosion, fire, or damage
to the equipment may result.

CAUTION- When wiring, follow the domestic laws and standards; otherwise, burning, electric shock, injury, or fire may result.
- The motor is not equipped with a protection device. However, it is compulsory to install an overload protector according to
the laws and standards. It is also recommended to install other protecting devices (earth leakage breaker,etc.), in addition toan over current protecting device; otherwise, burning, electric shock, injury, or fire may result.
- 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.
- When measuring the insulation resistance of explosion proof motor , confirm that there is no gas or explosive vapor in thevicinity. Otherwise, explosion or ignition may result.
- 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, ambient temperature conditions for standard units with andwithout brakes must be −10 to 40°C. (Manufacture with 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 and explosion proof types , check that terminal box mounting bolts are not loose, and correctly
attach the terminal box cover.

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 ResistanceMotor Voltage

6-7 Lubricating Oil Cooling Device
BEIER frame sizes 50A–200A, and 50B–150B come with a lubricating oil cooling device.
Install it together with the electric trochoid pump.

(1) Piping[1] Install the lubricating oil cooling device horizontally.
[2] The piping distance between cooling device and the Beier unit should be within the length shown in Table 6-4. Minimize the numberof bending locations of the pipe.
Table 6-4 Piping DistanceDirection
Upper side in vertical direction
Lower side in vertical direction
Horizontal direction

Length0.5m or less
1.5m or less3m or less[3] Check the lubricating oil inlet and outlet of the Beier unit and the lubricating oil cooling device on the manufacturing specifications,and perform piping work with gas pipes for the dashed line parts as shown in Figure 6-5.
[4] For the lubricating oil outlet of the Beier unit, use a gas pipe with 1 1/2B–2B in size. For the inlet, use a gas pipe with 1B in size.
The customer needs to prepare pipe materials and joints.

- Install the lubricating oil cooling device as close to the Beier unit as possible. Installing it too far from the Beier unit may cause asuction failure of the oil pump, resulting in abnormal sound, temperature rise, or insufficient lubrication.
- If the air is sucked from the middle of the pipe on the suction side of the oil pump, the oil supply amount decreases due to suction
failure, and abnormal sound is generated from the oil pump. Therefore ensure complete airtightness.

Figure 6-6 Pilot Motor (PM) Connection Example- Take the power supply for the pilot motor (PM) from the secondary power source for the main motor, and wire R-U, S-V, T-W.
- Confirm that pressing the speed acceleration button switch (PB4) increases the output shaft speed, and pressing the speed reduction
button switch (PB3) decreases the output shaft speed.
- If the pilot motor keeps rotating even after the variable speed reaches the highest speed and the lowest speed, excessive force isapplied. Because of this, idling the clutch allows the force of the pilot motor (PM) rotation to escape. Check if the clutch is idled when
the speed reaches the highest speed and the lowest speed.

Never stop the main motor during variable speed operation. Never attempt to perform variable speed operation while stopped.
Excessive force may be applied to the internal parts, resulting in damage to the disc, etc.

17Common

7. Operation
DANGER- Do not approach or touch the rotating parts (output shaft, etc.) during operation; otherwise, loose clothing may becomecaught in these rotating parts and cause serious injury or death.
- When the power supply is interrupted, be sure to turn off the power switch; otherwise, restoration of power may cause
electric shock, personal injury, or damage to the equipment.
- Do not operate the unit with the terminal box cover removed. Return the terminal box cover to the original position after
maintenance in order to prevent electric shock.

CAUTION- Do not put fingers or foreign objects into the opening of the product; otherwise, electric shock, injury, fire, or damage tothe equipment may result.
- The products becomes very hot during operation. Be careful not to touch with hands or body; otherwise, burns may result.
- Do not loosen the oil filler plug during operation; otherwise, hot, splashing lubricant may cause burns.
- If any abnormality occurs during operation, stop operation immediately; otherwise, electric shock, injury, or fire may result.
- Do not operate the products beyond the rated load; otherwise, personal injury or damage to the equipment may result.

7-1 Items to Check Before Operation
After installation and wiring are completed, check the following items before operating.
- Is the wiring correct?
- Is the unit properly coupled with the driven machine?
- Are mounting bolts tightened firmly?
- Is the direction of rotation as required?
- For oil-lubricated models, is the oil level at the center of the oil gauge or at the upper red line when the unit is at rest?
After confirming these items, operate without a load and gradually apply a load. Check the items shown in Table 7-1.
- Oil-lubricated models are shipped without oil. Before operating, make certain to feed the recommended or specified lubricatingoil (See P26–31). For BEIER-CYCLO Variator, the Beier unit and Cyclo unit need to be lubricated separately because of their
independence of lubrication.
- Never stop the main motor during variable speed operation. Never attempt to perform variable speed operation while stopped.
Excessive force may be applied to the internal parts, resulting in damage to the disc, etc.
- It is recommended to start the operation on the low speed side. When starting operation at full load or starting a model with a large
load moment of inertia, be sure to start the operation on the low speed side.
- In the case where the load moment of inertia is particularly large, soft-start may be required. Please consult with us.

7-2 Items to Check During Operation
Table 7-1 Items to Check During Operation

Does abnormal sound or vibration generate?

- Is the housing deformed because the installation surface is not flat?
- Is insufficient rigidity of the installation base generating resonance?
- Is the shaft center aligned with the driven machine?
- Is the vibration of the driven machine transmitted to the gearmotor or
reducer?

Is the surface temperature abnormally high?

- Does the voltage rise or drop substantially?
- Is the ambient temperature too high?
- Does the current value to the gearmotor exceed the rated current shown on
the nameplate?

Is the oil signal active?
(When the lubrication is of the plunger pump type)

If the ball in the oil signal is not moving up or down, there may be a lubrication
problem.

If any abnormalities are found, immediately stop operation and contact the nearest authorized maintenance shop.

7. Operation Common
7-3 Electric Trochoid Pump
CAUTION- For models with lubrication method using a electric trochoid pump, always start the electric trochoid pump before starting
the main motor. Abnormal temperature rise, seizure, or other damage to the device may result.
- For models with a lubricating method using electric trochoid pump, see P15.
- To ensure good lubricating conditions, start the electric trochoid pump before the main motor starts. See Table 7-2 for priming time
guideline

Priming Guideline
At least before 30 seconds or more
At least before 60 seconds or more
At least before 30 seconds or more

- For models with a lubricating oil cooling device, be sure to start the oil pump of the lubricating oil cooling device before starting themain motor, and check the oil feeding state.
- The time for the lubricating oil to circulate the entire machine differs depending on the piping distance, piping diameter, surrounding
environment, etc. Circulate the lubricating oil sufficiently before starting the main motor.
- When the ambient temperature is low such as in winter, the electric trochoid pump may cause vibration or noise in rare cases. Thisphenomenon will disappear as the oil temperature rises with operation, so this is not a problem.
- The pressure gauge is used to check the circulation of the lubricating oil. The pressure gauge may point around the upper limit orlower limit of the scale when the ambient temperature is high or low such as in summer or winter.
- To protect the pressure gauge, close the valve on the lower side of the pressure gauge when starting the electric trochoid pump. After
starting the pump, open the valve.

7-4 Variable Speed Operation/Manual Speed Change
Variable speed operation is performed by rotating the operation handle manually.
An electric remote control device is installed for the BEIER frame sizes 150A, 200A, 100B, and 150B as standard specification.
See P20–21 as well.
Never stop the main motor during variable speed operation. Never attempt to perform variable speed operation while stopped.
Excessive force may be applied to the internal parts, resulting in damage to the disc, etc.

(1) Indicator Plate Method- The operation handle can be attached to either right side or left side.
- When seen from the output shaft side, if the indicator moves from left to right by rotating the operation handle, the output shaft
speed increases. If it moves from right to left, the output shaft speed decreases.
- Calculate the output rotation frequency from the scale (speed ratio) indicated by the indicator.

7-5 Variable Speed Operation/Electric Remote Control Device (RC)
BEIER frame sizes 150A, 200A, 100B, and 150B come with an electric remote control device (RC) (This is an option for other frame sizes).
- Pressing the speed acceleration button switch increases the output shaft speed, and pressing the speed reduction button switch
decreases the output shaft speed. As long as the button switch is pressed, the pilot motor (PM) rotates and the speed is changed.
When the button switch is released, constant speed rotation is performed.
- Be sure to confirm that the pilot motor (PM) is stopped before changing from acceleration to deceleration, or deceleration toacceleration.
- If the pilot motor keeps rotating even after the variable speed reaches the highest speed and the lowest speed, excessive force isapplied. Because of this, idling the clutch allows the force of the pilot motor (PM) rotation to escape. If the clutch keeps idling for 30
seconds or more, a failure may occur. As soon as the variable speed operation is completed, release the button switch quickly to stop
the pilot motor (PM).
- If the clutch remains idled due to the specification of the variable speed control after the slowest speed or the fastest speed isreached, assemble a circuit that stops the pilot motor (PM) by the limit switch (option).
Never stop the main motor during variable speed operation. Never attempt to perform variable speed operation while stopped.
Excessive force may be applied to the internal parts, resulting in damage to the disc, etc.

Noise

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

Vibration

Is there abnormally large vibration? Are there extreme changes?
Is surface temperature unusually high? Is there a sudden rise?
There is no problem if the fluctuation is small with the following temperatures as upper limits.

Surfacetemperature

Oil level( Oil lubricatedmachines )Beier unit

Without lubricating oil cooling device:	Approx. 50°C in difference between surface temperature andambient temperatureWith lubricating oil cooling device:
Surface temperature of approx. 60°C

Cyclo unit

Frame size 6125 and smaller:	Approx. 40°C in difference between surface temperature andambient temperature
Frame size 6130 and above:	Approx. 60°C in difference between surface temperature andambient temperature

While stopped

Is the oil level below the center point or upper red line of the oil gauge when the machine isstopped?
If the oil level is below the center point or upper red line when the machine is stopped, replenish
lubricating oil to the center point or upper red line. Do not add the oil while the machine is running.

While running

The lower red line is an auxiliary mark serving as a guideline to check oil level while the machine isrunning.

In the case of
Trochoidpump method

Lubricant contamination
Oil, grease leaks

Electric trochoid pump
(Beier unit)

Are the oil signal and flow gauge working properly?
Not working properly is a sign of improper reducer lubrication, due to factors including insufficientoil, pump damage and plugged pipes. In this case, immediately stop the machine and inspect it.
Is the lubricating oil contaminated?
Oil contamination can be checked by extracting oil while the machine is stopped or by using the oil
gauge.
If the oil gauge is contaminated, promptly change it.
Are oil or grease leaking from the gear unit? Are the oil seal sliding surfaces corroded?

Note: 1. D Type (ND series: with N in frame size) and former D Type (without N in frame size) differ in lubricating oil to be used.
2. In the case of D Type BEIER-CYCLO Variator, the Cyclo unit and Beier unit differ in lubricating oil to be used.
[1] When using in winter or where the ambient temperature is relatively low, use an oil with low viscosity shown in the table below.
In the case of forced lubricated models, if the plunger pump or electric trochoid pump causes cavitation, required quantity of oil
cannot be fed, and the product may incur fire damage.
[2] For N02A and N02B, use oil with low viscosity shown in the table below.

8. Daily Inspection and Maintenance Common(4) Procedures for Filling and Discharging
Grease replenishment procedure for grease lubricated models (excluding long-life grease lubricated models)[1] Remove the grease discharge plug from the casing.
[2] U se a grease gun to replenish the grease from the grease fitting on the internal cover, referring to the quantity of grease shown in
Table 8-23 on P32 as guidelines. If a grease fitting has a metal cap, remove the cap before replenishing. After replenishing, attach themetal cap.
[3] Replace the grease discharge plug.

Metal cap

Grease discharge plug

Figure 8-8 Location of Grease Fill and Discharge Port
(Example: Horizontal Type BEIER-CYCLO Variator 2 Stage Reduction)

Figure 8-9 Grease Fitting with Metal Cap- Replenish grease while the machine is running to improve grease distribution.
- In addition to being used for discharging grease, the grease discharge plug also functions as a pressure vent when replenishinggrease. Make certain to remove when replenishing.
- Replenish grease slowly.
- Replenishing more than the quantity shown in Table 8-23 on P32 may cause agitation heat, which raises the temperature, and may
cause grease to leak into the Beier unit.
- Grease may leak out of the grease fitting after starting the machine. In such a case, replace the grease fitting with one that has ametal cap.
- Be careful when handling the metal cap for the grease fitting as dropping it from a high place is dangerous.
- Contact the nearest authorized maintenance shop concerning changing all of the grease in a grease lubricated model.

8-6 Main Unit Maintenance- Although it will depend on operation conditions, maintenance with disassembly after approximately 20,000 hours or 3 to 5 years will
increase lifetime.
Contact the nearest authorized maintenance shop regarding maintenance with disassembly.
- Oil seals have a lifetime. During long use, natural degradation and frictional wear will reduce effectiveness. Depending on theoperating conditions and ambient environment for this product, the lifetime of seals greatly varies. Given normal operation, (uniform
load, running 10 hours per day, normal temperature) it is recommended to change them every 1 to 3 years. If the sliding surfaces of oil
seals or V-rings show signs of wear or corrosion, replace them with new ones. Because sliding surfaces for oil seals are made of carbon
steel, take periodic rust prevention measures not to spread rust on them by applying rustproof oil and so on, if there are exposed
surfaces of steel.
Please consult with the nearest maintenance shop for the replacement of oil seal or V-ring.
- If the unit stops and starts frequently, mounting bolts (or nuts) and ring gear housing fastening bolts (or nuts) may come loose.
Periodically check for looseness as this is a source of misalignment, oil leakages, and load unbalance.

100- Only use grease listed in Table 8-26.
- Replenishment quantity is the quantity of grease to refill the bearing with at each interval.
- Even in the case of intermittent operation, replenish grease at least every 3 years.
- If the machine is rested for a long time, replenish grease immediately after resuming operation.

(4) Replenishment Procedure
Replenish new grease from the grease fitting (See Figure 10-2 on P37) during operation.
(Grease change will be incomplete if replenishing is done while the machine is stopped.)- 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. Daily Inspection and Maintenance Common
8-8 Motor Bearing Maintenance- Standard motors manufactured by Sumitomo use sealed bearings (without grease filling and discharging structure).
- When using another manufacturer’s motor, refer to the operation manual for that motor.
(Motors with a motor capacity of 37kW or more are made by other manufacturers. Also, depending on the motor specification, somemotors are made by other manufacturers.)- Although it will depend on operation conditions, maintenance with disassembly after approximately 20,000 hours or 3 to 5 years will
increase lifetime.
- Contact the nearest authorized maintenance shop regarding maintenance with disassembly.

8-9 Inspection and Cleaning for Oil Cooling Component
Inspect and clean the oil cooling component of the lubricating oil cooling device for BEIER frame sizes 50A–200A, and 50B–150B
periodically.
- Although the inspection timing varies depending on the degree of lubricant contamination and water quality of coolant, be sure to
perform inspection every 3 to 6 months.
- Check the internal water contamination state by removing the hood on the U-turn side. Check the degree of lubricant contamination
by discharging the oil from the drain plug.
- Be sure to check the anticorrosive zinc bars (3 locations) during inspection. If the bars have been reduced to half or less, replace them.
Depending on the water quality, the replacement may be required in 3 to 6 months.
- When operation is stopped in an environment where the coolant freezes in winter, be sure to discharge the coolant. When the surface
temperature of the Beier unit case can be kept at approx. 40–45°C in ambient temperature at which the coolant freezes, reduce thecoolant water supply or stop the lubricating oil cooling device.
