Replace the component, then set o4-03, o4-05, o4-07, and o4-09 [Maintenance Setting] = 0 to reset the
Maintenance Monitor. If these parameters are not reset after the corresponding parts have been replaced, the
Maintenance Monitor function will continue to count down the performance life from the value that was reached
with the old part. If the Maintenance Monitor is not reset, the drive will not have the correct value of the
performance life for the new component.
Note:
The drive installation environment has an effect on the maintenance period.

Replace a Cooling Fan and Circulation Fan
NOTICE
Follow cooling fan replacement instructions. Replace all fans when performing maintenance to help ensure
maximum useful product life. Improper fan replacement could cause damage the drive.
To replace a cooling fan or circulation fan, contact Yaskawa or your nearest sales representative.

Cause
The cooling fan is at 90% of its
performance life estimate.
The main circuit and control circuit
capacitors are at 90% of their
performance life estimate.
The soft charge bypass relay is at
90% of its performance life estimate.
The IGBTs are at 50% of their
performance life estimate.
The IGBTs are at 90% of their
performance life estimate.
Table 7.10 Maintenance Setting Parameters
Sets the value from which to start the cumulative drive cooling fan operation time in
10-hour units.
Note:
When o4-03 = 30 has been set, the drive will count the operation time for the
cooling fan from 300 hours and U4-03 [Cooling Fan Ope Time] will show 300 h.
Sets the value from which to start the count for the main circuit capacitor
maintenance period as a percentage.
Sets as a percentage the value from which to start the count for the soft charge bypass
relay maintenance time.
Sets the value from which to start the count for the IGBT maintenance period as a
percentage.
