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 fuse
• IGBT

Replacement Parts

Table 7.3 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.
Cooling Fan
Electrolytic Capacitors (Main Circuit)
<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 40°
C • Load factor: 80% maximum • Operation time: 24 hours a day
Performance Life Monitors
n
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.

NOTICE: After replacing parts, reset the appropriate maintenance parameters (o4-03, o4-05, o4-07, and o4-09) to 0. If these parameters are not reset, the function will continue
to count down the performance life of the new replaced components.

Displays the accumulated operation time of the cooling fan, from 0 to 99999 hours. This value is automatically reset to 0 once
it reaches 999999.
Displays the accumulated cooling fan operation time as a percentage of the specified maintenance period (displayed in percent
%).
Displays the accumulated time the capacitors are used as a percentage of the specified maintenance period.
Displays the number of times the drive is powered up as a percentage of the performance life of the inrush circuit.
Displays the percentage of the maintenance period reached by the IGBTs.
