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

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 temperature.

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

(Otherwise, grease leaking is possible.)

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.

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 biting.

•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.

■ Be sure to ground the grounding terminal.

In wiring to power supply (outside of equipment) from NFB, use an electric wire of 1.6 mm diameter (2.0 mm2) or more both for main circuit and grounding. Apply grounding class D (100

ohms or below) for grounding.

●Selection of relay

As for use for control circuit such as control input terminal, use a relay for small signal (minimum guarantee current 1 mA or less) for preventing poor contact. <Reference example> Matsushita Electric Works, Ltd: DS type, NK type, HC type, OMRON: G2A type

● Control Circuit Switch

When using a switch instead of relay, use one for minute current in order to prevent poor contact. <Example> Nihon Kaiheiki: M-2012J-G

potentiometer Rotationdirection Power selecting lamp switch

RUN/STOP switch

(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).

		Expected of life	Standard life
	Service factor (Sf)
			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:

	Type of load	Example of load		Service factor
			5 hours/day	8 hours/day	24 hours/day
	Uniform load	One direction continuous operation	0.8	1.0	1.5
	Light shock	Start, stop, or cam shock	1.2	1.5	2.0
	Middle shock	Instantaneous rotation/reverse rotation and instantaneous stop	1.5	2.0	2.5
	Heavy shock	Middle shock at a high frequency	2.5	3.0	3.5

Permissible shaft torque

Required shaft torque TA of gear head can be obtained from service factor and actual load torque T1.

TA=T1×Sf

Select a gear head and motor to ensure that required torque (continuous) is within permissible shaft torque in the table below. Here, the torque T1 must not exceed permissible shaft torque TA irrespective of Sf.

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:

Mounting	Type of	Screw	Tightening torque	Mounting

How to clear trip

If the motor should trip, eliminate the cause and use any of the procedures [1] – [3] below for clear.

[1]	Turn off power, and when power LED has gone out, turn on power again.
[2]	Press the switch	>>	and	>>	of the Digital key pad simultaneously for one second or more with present trip
	state displayed.

[3] Input the trip reset signal.

(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.
