Safety Precautions <strong>common</strong> <br />
Operation <br />
Caution<br />
20. The motor is not equipped with protection means. Install an earth leakage<br />
breaker, an excessive temperature rise prevention means and an<br />
emergency stop unit as necessary protection measures.<br />
Failure to do so may result in an injury or a fire accident.<br />
21. Do not touch the radiation fin of the amplifier or the motor while the power<br />
is on or for a while after the power has been turned off, as these parts<br />
generate excessive heat. Burn could otherwise result.<br />
22. In the event of any abnormality, stop operating the system immediately.<br />
Failure to do so may result in electric shock, injury, or fire.<br />
23. Never make an extreme adjustment change that will cause the system<br />
operation to become unstable. Doing so may result in injury.<br />
24. At trial operation, fix the motor and check the operation separate from the<br />
mechanical system, then install the system on the machine. Failure to do<br />
so may result in an injury.<br />
25. The holding brake is not a stop unit to secure the safety of the machine.<br />
Install a stop unit to secure the safety on the machine side.<br />
Failure to do so may result in an injury.<br />
26. When an alarm occurs, remove the cause of the alarm and secure safety.<br />
After that, reset the alarm, then result the system operation. Failure to<br />
follow this procedure may result in an injury.<br />
27. After a recovery from an instantaneous power interruption, the operation<br />
may be restarted suddenly. Do not approach the machine. (Design the<br />
machine so that safety for personnel may be secured even if the system<br />
operation is restarted.)<br />
Approaching the machine when it restarts may result in an injury.<br />
28. Make sure the supply voltage is within the specified range. If the supply<br />
voltage is out of specification, functional failures may occur.<br />
Maintenance <br />
29. The amplifier frame becomes very hot. Take care to avoid burns when<br />
doing maintenance and inspection.<br />
30. It is recommended to replace the electrolytic capacitors in the amplifier<br />
after 5 years, if used at an average temperature of 40 year around.<br />
31. When repair is required, please contact us.<br />
Disassembly of the system by the user may render it inoperable.<br />
Transportation <br />
32. Make sure the device does not fall or overturn during transportation.<br />
33. Do not hold the unit by the cables or the motor shaft.<br />
Doing so may result in injury or equipment failure.<br />
Scrapping <br />
34. When discarding the amplifier and the motor, dispose of it as a general<br />
industrial waste.<br />
