CHAPTER 19. MAINTENANCE AND INSPECTION
CAUTION Maintenance and Inspection ☞
▶ After cutting off the main power and enough time passed, check and maintain. Due to the residual
voltage at capacitor, it is very dangerous.
▶ Do not test the servo amplifier with a megger(measure insulation resistance), or it may becomes
faulty.
▶ Do not disassemble and/or repair the equipment on customer side
19-1. INSPECTION
It is recommended to make the following checks periodically.
1. Check for loose terminal block screw. Retighten any loose screws.
2. Check the cables and the like for scratches and cracks. Perform periodic inspection according to
operating condition.
3. Check the servo motor bearings, brake section, etc. for unusual noise.
4. Check the servo motor shaft and coupling for misalignment.
19-2. LIFE
The following parts must be changed periodically as listed below.
If any part is found faulty, it must be changed immediately even when it has not reached the end of
its life, which depends on the operating method and environmental conditions.
With age, the smoothing capacitor will deteriorate. To prevent a second accident due to fault, it is
recommended to replace the electrolytic capacitor every 5 years when used in general environment.
For parts replacement, please contact your sales representative.
