7. Operation
DANGER
●
Do not go close to or touch the rotating parts (such as output shaft). It may cause injury by getting caught and may result in
serious injury or death.
●
Turn off the power switch when blackout occurs. Unexpected start may cause electric shock, injury, or damage to the equipment.
●
Do not operate the unit without terminal box cover. Attach the cover to the same place after maintenance before operating.
Failure to do so may cause electric shock.
●
Do not remove the terminal box cover while the power is on. It may cause explosion, ignition, electric shock, injury, fire, or
damage to the equipment.
CAUTION
●
Do not put finger or any foreign object in the opening of gearmotor and reducer. It may cause electric shock, injury, fire, or
damage to the equipment.
●
Gearmotor and reducer become very hot during operation. Do not touch with any part of your body. It may cause burns.
●
Do not make to oil filler plug loose during operation. It may cause burns by the splash of hot lubrication oil.
●
Stop the operation immediately when any abnormality is found. Failure to do so may cause electric shock, injury, or fire.
●
Do not operate the unit while exceeding the rated load. It may cause injury or damage to the equipment.
•
Oil-lubricated models
have their oil drained before shipping. Supply recommended lubrication oil before operation.
• Some models need supply of lubrication oil at two places (for output side BUDDYBOX and input side CYCLO).
Check the following before operation when mounting, oil supply, and wiring is complete.
1. Is the wiring correct?
2. Is the coupling with the driven machine correct?
3. Are mounting bolts tightened?
4. Is the rotational direction as planned?
5. Is the level of oil level at the center point of the oil level gauge at stop for oil lubrication
models?
Make sure the answer is yes to all of the questions above. Then, start trial run with no load, and
apply load gradually. Ask the questions in Table 6 and make corrections during trial run.
Table 6 Checkpoints for Trial Run
When there is abnormal
noise or vibration
1. Is there any twist in the housing, because the mounting surface is not flat?
2. Is there any resonance, because the rigidity of mounting block is insufficient?
3. Is there any misalignment with the driven machine?
4. Is the vibration of the driven machine transmitted to the gearmotor or reducer?
When the surface
temperature of the
gearmotor or reducer is
abnormally high
1. Is the voltage increase or decrease large?
2. Is the ambient temperature too high?
3. Is the current exceeding the rated current shown in the nameplate
for gearmotors
?
Stop operation when any abnormality is found. Contact your agent, distributor, or sales office.
