6.3 Periodic Maintenance
6.3 Periodic Maintenance
The drive has a maintenance monitor. The 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 the accumulated performance life for cooling
fans an electrolytic capacitors in the main and control circuits.
◆ Replacement Parts
Table 6.3 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 6.3 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
• Load factor: 80% maximum
• Operation time: 24 hours a day
■
Performance Life Monitors
The drive calculates the maintenance period for components that may require
replacement during the life of the drive. A percentage of the maintenance period is
displayed on the LED digital operator by viewing the appropriate monitor
parameter.
When the maintenance period reaches 100%, there is increased risk that the drive
may malfunction. Yaskawa recommends checking the maintenance period
regularly to ensure maximum performance life.
