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
component.
When the specified component is near the end of its performance life estimate, the MFDO terminals set for H2-xx
= 2F [Maintenance Notification] will activate, 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.

Shows the total operation time of fans as 0 to 99999 hours. After this value is 99999, the drive automatically
resets it to 0.
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, 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.
