◆ Periodic Maintenance
The drive has Maintenance Monitors that keep track of component wear. This feature provides advance maintenance
warning and eliminates the need to shut down the entire system for unexpected problems. The drive allows the user to
check predicted maintenance periods for the components listed below.
• Cooling Fan, Circulation Fan, Control Board Cooling Fan
• Electrolytic Capacitors
• Inrush Prevention Circuit
• IGBTs
For replacement parts, contact the distributor where the drive was purchased or contact Yaskawa directly.
■ Replacement Parts
Table 42 contains the estimated performance life of components that require replacement during the life of the drive. Only
use Yaskawa replacement parts for the appropriate drive model and revision.
Table 42 Estimated Performance Life
NOTICE: Estimated performance life based on specific usage conditions. These conditions are provided for the purpose of replacing
parts to maintain performance. Some parts may require more frequent replacement due to poor environments or rigorous use. Usage
conditions for estimated performance life:
Ambient temperature: Yearly average of 40 °C (104°F) (IP00 enclosure)
Load factor: 80% maximum
Operation time: 24 hours a day
Circuit Boards
Check for any odor, discoloration, and rust. Make
sure connections are properly fastened and that no
dust or oil mist has accumulated on the surface of the
board.
• Fix any loose connections.
