6.3 Periodic Maintenance
The drive has various "maintenance monitors." 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 the following maintenance periods.
• Cooling Fan
• Electrolytic Capacitors (Main Circuit)
• Inrush Prevention Circuit
• IGBT

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
Component Estimated Performance Life
Cooling Fan 2 ~ 3 years
Electrolytic Capacitors (Main Circuit)
10 years
<1>
<1> The drive has few serviceable parts and may require complete drive 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 30 °C
• Load factor: 80% maximum
• Operation time: 12 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.
Refer to Recommended Periodic Inspection on page 173 for more details.
