Alarm Outputs for Maintenance Monitors
You can use H2-xx [MFDO Function Selection] to send a message that tells you when a specified component is near
the end of its performance life estimate. Set the applicable value to H2-xx as shown in
When the specified component is near the end of its performance life estimate, the MFDO terminals set for H2-xx =
2F [Maintenance Notification] will turn ON, and the keypad will show an alarm that identifies the component to
replace.

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 maintenance period changes for different operating environments.

Table 1.8 Performance Life Monitors
Parts
Shows the total operation time of fans as 0 to 99999 hours. After this value is 99999, the drive automatically resets it
to 0.
Cooling fan
Shows the total fan operation time as a percentage of the specified maintenance period.
Shows the total capacitor usage time as a percentage of the specified maintenance period.
Shows the number of times the drive is energized as a percentage of the performance life of the inrush circuit.
Shows the percentage of the maintenance period for the IGBTs.

Name
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.
Description
Replace the cooling fan, then set o4-03 = 0 [Fan Operation
Time Setting = 0 h] to reset the cooling fan operation time.
Replace the board or the drive.
Contact Yaskawa or your nearest sales representative to
replace the board.
