Alarm Outputs for Maintenance Monitors
You can use H2-xx [Multi-Function Digital Out] 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 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 drive installation environment has an effect on the maintenance period.

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
