Precaution for proper use

1. This motor incorporates control circuit. Control circuit is sensitive to temperature and impact, therefore read this instruction manual carefully for proper installation.

2. This motor is controlled by switching the power element at a high speed. Therefore, when the motor runs, leaking current may increase, which activates the leakage breaker. In such a case, use a leakage breaker which is provided with measure against high frequency for inverter.

3. In starting and stopping the motor, use the operation instruction input "I1" or RUN/STOP switch of console A and digital key pad. When the motor is turned on and off by turning on and off power supply, the life of inner circuit may be shortened.

Installation

Install the brushless motor properly for preventing failure and accident.

Transport

● Use caution enough in transporting the unit to prevent injury by drop or fall, and avoid damage to

the equipment.

Storage

● Keep the unit indoors in a clean and dry place free from vibration with little change of tempe rature.

● In keeping a gear head alone, direct the output shaft down.

Location

● Location gives great influence upon the life of brushless motor, therefore choose a place in

conformance with the conditions below:

(1) Indoors where the motor is not subjected to rain water and direct sun beam. (2) Do not use the motor in corrosive atmosphere such as hydrogen sulfide, sulfurous acid, chlorine, ammonia,

sulfur, gas chloride, gas sulfide, acid, alkali, and salt, in the atmosphere of combustible gas, or in the vicinity of

flammables. (3) Place not exposed to grinding liquid, oil mist, iron powder, and cutting particle. (4) Well-ventilated place with little moisture, oil, or inundation, and place far from heat source such as a furnace. (5) Place easy to check and clean (6) Place free from vibration (7) Do not use the unit in an enclosed environment. Enclosing may raise the temperature of motor, and shorten

their life.

(Otherwise, grease leaking is possible.)

Caution in Installing Gear Head

● Idling by damaged tooth, locking by bite, grease leakage, and the like are possible on the life end of gear head. Install a safety device in order to ensure safety even if such trouble should be found.

• Install a device for preventing drop by damaged teeth on a lifter or the like.

• As for application such as opening and closing of door, install a release device against locking by gear bit ing.

• As for food or textile equipment, install an oil pan for measure against grease leakage.

• Do not install an encoder, sensor, contact, etc in the proximity of gear head. If you should install such devices,

take measures against their grease leakage.

• Be sure to perform daily check in order to prevent unexpected accident.

Installation/System configuration and wiring

Others

● Oil and water protections

(1) Direct down the lead of cable as far as possible. (2) Avoid use in such an environment where motor is always exposed to oil and water. (3) Avoid use with cable immersed in oil and water.

● Cable: stress relieving (1) Make sure that stress is not applied to the lead or connection of cable due to bending or dead weight.

(2) In installation where the motor moves, fix the cable of motor, incorporate the extension cable

connected beyond in the cable carrier to reduce stress by bending as small as possible.

(3) Allow the bending radius of cable as large as possible.

Rotation direction is that on motor shaft. When gear head is incorporated, the rotation direction of motor and that of gear output shaft

are reversed for some gear reduction ratio. See the allowable shaft torque table on page 8. (CW: Rotation clockwise when seen from the motor shaft, CCW: Rotation counterclockwise when see from the motor shaft)

When resistor and control GND are disconnected in use of external variable resistor, 5V is input to FIN irrespective of setting of

variable resistor, and upper speed limit is directed; therefore use caution enough for connecting GND.

(Check before operation)

(1) Any mistake found in wiring? (2) Input power supply conforms to rating?

(Test run)

When RUN/STOP switch is changed to RUN, the motor rotates, and when the switch is returned to STOP, the motor stops. Rotation direction can be changed by rotation direction selecting switch on the side of console. When the rotation direction is changed in RUN, the motor is inverted suddenly, and the motor may trip due to some inertia of load. Rotation speed can be adjusted by the speed potentiometer. Turn off power when the motor is to be stopped for a long time.

■ When power is turned off with RUN/STOP switch on RUN side, and power is turned on again, the motor may start again, which is dangerous. In turning on power, always make sure that the switch is on STOP side.

■

When a gear head is incorporated, rotation direction of gear head output shaft may be inverted for some gear reduction ratio. See the table of allowable shaft torque on page 8.

Checking the load and use condition

Check use condition for eternal use of this product. Some use conditions may possibly lead to heating or damage to the shaft. Fully check use conditions, and use the motor in a permissible range.

Standard life

Standard life is 5,000 hours for the motor equipped with gear head (MB8G and MB9G). Standard life is the same 10,000 hours for motor alone (round shaft). (Standard life of sealing performance of oil seal is 5,000 hours.)

Standard life refers to design life for operation 8 hours per day (service factor: Sf = 1.0) at a normal temperature and humidity, under uniform load (permissible shaft torque of gear head and rated torque of motor).

Service factor (Sf)

Service factor (Sf) depends on the magnitude of shock of load or operating time. Service factor is shown below for different load conditions:

Maintenance and inspections/Assembling of Gear Head

Assembling of Gear Head

● Preparation before assembling

(1) Compatible gear head described on this instruction manual is MX8G□B (for 30, 50W) and MZ9G□B

(for 90, 130W). Never combine anything other than compatible gear head in use. Failure to observe this direction may result in malfunction. (□ represents speed reduction ratio.)

(2) Make sure that the O-ring is attached to the bottom of motor flange.

If the gear head is assembled with O-ring floating, it may result in grease leakage.

(3) When grease adheres to the end surface of gear head, wipe off sufficiently.

If the gear head is assembled with grease adhered, it may cause grease to exude.

● Assembling

(1) Direct the motor pinion upward, and make sure that the relation between direction of motor lead wire

and output shaft matches with the equipment.

(2) Turn the motor pinion finely clockwise and counterclockwise for assembling, ensuring that the tip of

motor pinion does not hit the tooth of gear head.

(3) In installing the motor and gear head to the mating equipment, use "mounting screws" attached to the

gear head, tighten them sufficiently to eliminate clearance between the motor flange surface and gear head end surface while paying attention to bite of O-ring. Recommended tightening torque is shown below:

■Trip can be set by parameter 50.

100V product: Approx DC100V, 200V product: Approx DC200V

The motor trips when internal DC voltage is below specified value only if trip is set by parameter 50. 100V product: Approx DC100V, 200V product: Approx DC200V When load factor exceeds specified value, the electronic thermal relay operates and monitor display flashes. It is a warning for electronic thermal trip.

detected. The motor trips when rotation speed (actual speed)

exceeds specified value. Approx 4500r /min

The motor trips when the temperature in control section rises above specified value. Approx 105℃

The motor trips when any important parameter such as " 30 Run command selection" is changed

Investigate the condition of wiring and circumstances of power supply.

Reduce the load. Check the load factor in monitor mode.

Investigate the cause of overload, and reduce the load, change the operating pattern by making acceleration and deceleration time longer, or apply design to increase the capacity of motor.

Excessive acceleration/deceleration setting or gain setting is possible. Set the longer acceleration/deceleration time and the smaller gain. If this trip should occur as soon as the unit is started, failure is possible.

If the motor should trip in running, too short deceleration time is one of the causes. Adjust deceleration time. No measure can be taken in continuous regenerative operation such as lowering.

Check all parameters again and set them again. If this protection works frequently, failure is possible

①Malfunction due to external noise is possible.

Investigate for noise source in the vicinity and

eliminate such source.

②Internal circuit may be in failure.

Ensure that the actual speed does not exceed rated rotation speed, such as overshooting by unmatching between load and gain.

Check the ambient temperature and cooling condition of motor. Check the load factor. If the ambient temperature is low enough, and the protection occurs soon after power-on, failure is possible.

This is not abnormal. Trip reset in order to make change effective.

(When F-r or r-F is chosen in " 33 I1/I2 function selection", enter "I1" and "I2" at the same time; when F-rST or r-rST is chosen, enter "I2" for trip reset. Trip reset signal, when continued to be input, is designed to become ineffective in order to prevent inadvertent restarting. Enter trip reset signal only when necessary.)

Note: As for overcurrent error E-OC , sensor error E-CS , System error Err , and user parameter error E-Upr , reset them by turning off power as shown in [1] above. No other procedure is effective.

(Caution) In clear trip, be sure to find and remove the trip factor before clear.
