18. Mount the product on an incombustible material such as metal. Doing
otherwise may cause fire.
19. Confirm the rotating direction before connecting with the mechanical
device. Failure to do so may cause injury or a breakdown.
20. Do not touch the motor output spindle (including the key slot and gears) with a bare
hand. Doing so may cause injury.
＜
Operation
＞
21. The stepping motor is not equipped with any protective device. Take
protective measures using an over-current protective relay, a ground fault
interrupter, a protective device from excess temperature, and an emergency
stopping device. Failure to do so may cause injury or fire.
22. Do not touch the product for a period after the power is on or has been turned
off, since the driver and stepping motor remain in the high temperature. Doing
so may cause burns. Especially the temperature rises considerably of the
stepping motor depending on the operating conditions. Use the motor on the
condition so that its surface temperature becomes 100°C or under.
23. Stop the operation immediately when an emergency occurs. Failure to do so may
cause an electric shock, injury or fire.
24. Do not change adjustment to an extreme, for such a change results in the unstable
operation. Doing so may cause injury.
25. When conducting the trial operation, make the stepping motor fixed firmly, and
confirm the operation by disconnecting with the mechanical system before
connecting with it. Failure to do so may cause injury.
26. When the alarm has been activated, eliminate the cause and ensure the
safety to resume operation. Failure to do so may cause injury.
27. When the electric power recovers after the momentary interruption, do not
approach the devices because the system may re-start operation by itself.
(Set the system so as to secure the safety even when it re-start on such
occasion.) Failure to do so may cause injury.
28. Confirm that the electric power supply is all proper conforming to the
specifications. Failure to do so may cause a trouble.
29. The brake mechanism of the motor with the electro-magnetic brake is to
hold the movable section and the motor position. Do not use it as a safety
measure, or doing so may cause the breakdown of the system.
30. Fix the key firmly when operating the motor with key individually. Failure to
do so may cause injury.
＜
Maintenance services
＞
31. Be careful when performing maintenance services or inspection about the
temperature which rises highly in the driver and stepping motor frame.
Failure to do so may cause burns.
32. It is recommended to replace the electrolytic condenser of the driver with a
new one for securing the preventive measure after using for 5 years, the
expected life in the average 40°C. The expected life of the fuse and cooling
fan motor is 10 years in the average 40°C. Thus, the periodical replacement
is recommended.
33. Contact with us for repair. If the product is disassembled by the user, it may
put it out of action.
＜
Transportation
＞
34. Handle the product with care during transportation so as to prevent from the
danger such as a tumble or a turnover.
35. Do not hold with the cable or the motor spindle. Doing so may cause a
trouble or injury.
＜
Retirement
＞
36. When scrapping the driver or stepping motor, treat it for the general
industrial waste.
＜
Storage
＞
1.
Avoid the place exposed to rain or water drops, or in an environment with
hazardous gas or liquid for storing the product. Failure to do so may cause a
trouble.
＜
Maintenance services
＞
2.
Do not assemble or repair the product. Doing so may cause fire or an
electric shock.
＜
General matters
＞
3.
Do not remove the rating plate.
＜
Storage
＞
1.
Store the product within the specified conservation temperature and
humidity in the place not exposed to the sun beam.
2.
If the driver has been stored for a long period (3 years or longer for a guide),
consult with us. The capacitance may have decreased with the electrolytic
condenser due to the long period storage, and it may cause a trouble.
＜
Operation
＞
3.
Install an external emergency stop circuit to turn the power off for the
instant halt of operation.
4.
Put the product into operation in the specified ambient temperature and
humidity.
＜
Transportation
＞
5.
Excess loading of the product on the carrier may cause the load to fall in
pieces. Follow the instructions given outside the package.
＜
General matters
＞
1.
Do not use the product in an explosive, flammable or corrosive atmosphere, watery
place or near a combustible material. Doing so may cause injury or fire.
2.
Have a person with expert knowledge for performing the transportation,
placement, wiring, operation, maintenance or inspection of the product.
Without such knowledge, it may cause an electric shock, injury or fire.
3.
Do not work for wiring, maintenance servicing or inspection with the electric
power on. Perform either of those five minutes after turning the power off,
or otherwise, it may cause an electric shock.
4.
When the protective functions of the product is activated, turn the power off
immediately and eliminate the cause. If continuing the operation without
eliminating the cause, the product may operate improperly and cause injury
or a breakdown of the system devices.
5.
Stepping motor may run out of order at the operating and stopping
occasions, depending on the magnitude of the load. Put the product into use
after confirming with the adequate trial test operation in the maximum load
conditions that the product performs reliable operation. Doing otherwise
may cause a breakdown of the system. (Should the product run out of order
in the use to drive upward/downward, it may cause a fall of the load.)
6.
Do not touch the internal parts of the driver. Doing so may cause an electric
shock.
＜
Wiring
＞
7.
Do not connect the stepping motor directly with the commercial power
outlet. Doing so may cause an electric shock, injury or fire. The power shall
be supplied to the stepping motor through the driving circuit.
8.
Use the electric power source within the rated input voltage. Using
otherwise may cause fire or an electric shock.
9.
Connect the driver and stepping motor to the ground. Using without
grounding may cause an electric shock.
10. Do not harm, forcibly put a stress, or load a heavy article on the cable or get
it caught between the articles. Doing so may cause an electric shock.
11. Perform wiring with the power cable as instructed by the wiring diagram or
the Operation Manual. Doing otherwise may cause an electric shock or fire.
＜
Operation
＞
12. Be sure not to touch the rotating part of the stepping motor during its
operation. Touching it may cause injury.
13. Neither reach or touch the electric terminals while electric power is on.
Doing so may cause an electric shock.
14. Never disconnect any of the connectors while electric power is on. Doing so may
cause an electric shock and corruption.
＜
General matters
＞
1.
Prior to placement, operation, maintenance servicing or inspection, be sure
to read the Operation Manual and follow the instructions to perform those.
Failure to follow the instructions may cause an electric shock, injury or fire.
2.
Do not use the driver or the stepping motor outside the specified conditions.
Doing so may cause an electric shock, injury or fire.
3.
Do not insert a finger or a thing into the opening of the product. Doing so may cause
an electric shock, injury or fire.
4.
Do not use the damaged driver or stepping motor. Doing so may cause
injury, fire or the like.
5.
Use the driver and stepping motor in the designated combination. Using
otherwise may cause fire or a trouble.
6.
Be careful that the temperature rises in the operating driver, stepping motor
or peripheral devices. Failure to be careful may cause a burn.
＜
Unpacking
＞
7.
Unpack while confirming the ceiling. Failure to do so may cause injury.
8.
Confirm if the product is the one having been ordered. Installing an incorrect
product may cause a breakdown.
＜
Wiring
＞
9.
Do not perform measurement of the insulation resistance or withstand
insulation voltage of the product. Doing so may cause a breakdown. Instead,
contact with us for such inspection.
10. Perform wiring conforming to the technical standards of electric facility or
the internal rule. Doing otherwise may cause burning or fire.
11. Ensure that wiring has been correctly done. Operating without correct
wiring may cause the stepping motor to run out of control and result in
injury.
12. Take insulation process for the attached condenser or the external resistance
connection terminals. Failure to do so may cause an electric shock.
＜
Placement
＞
13. Do not climb or attach a heavy article on the product. Doing so may cause
injury.
14. Neither block nor stuff the aspiration/exhaust vent with a foreign particle.
Doing so may cause fire.
