7.3 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 7.3 contains the estimated performance life of components that require replacement during the life of the drive. Only
use OYMC replacement parts for the appropriate drive model and revision.
Table 7.3 Estimated Performance Life
Component Estimated Performance Life
Cooling Fan 10 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 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. OYMC recommends
checking the maintenance period regularly to ensure maximum performance life.
Refer to Recommended Periodic Inspection on page 264 for more details.
Table 7.4 Performance Life Monitors Used for Component Replacement
Parameter Component Contents
U4-03
Cooling Fan
Displays the accumulated operation time of the cooling fan, from 0 to 99999 hours. This value
is automatically reset to 0 once it reaches 99999.
U4-04
Displays the accumulated cooling fan operation time as a percentage of the specified
maintenance period (displayed in percent %).
U4-05
Main Circuit (DC bus)
Electrolytic Capacitors
Displays the accumulated time the capacitors are used as a percentage of the specified
maintenance period.
U4-06 Inrush (pre-charge) relay
Displays the number of times the drive is powered up as a percentage of the performance life
of the inrush circuit.
U4-07 IGBT Displays the percentage of the maintenance period reached by the IGBTs.

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.
