Periodic Maintenance - YASKAWA D1000 Series Instruction Manual

6.2

Periodic Maintenance

The converter 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 converter 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
For replacement parts, contact the distributor where the converter was purchased or contact Yaskawa directly.
◆ Replacement Parts
Table 6.3 contains the estimated performance life of components that require replacement during the life of the converter.
Only use Yaskawa replacement parts for the appropriate model and revision.

<1> The converter has few serviceable parts and may require complete converter replacement.
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 (IP00/Open Type enclosure)
Load factor: 80% maximum
Operation time: 24 hours a day
Performance Life Monitors Maintenance Monitors
■
The converter calculates the maintenance period for components that may require replacement during the life of the
converter. A percentage of the maintenance period is displayed on the digital operator by viewing the appropriate monitor
parameter.
When the maintenance period reaches 100%, there is increased risk that the converter may malfunction. Yaskawa
recommends checking the maintenance period regularly to ensure maximum performance life.
