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.

Name

Function

o4-03

Fan Operation Time Setting

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.

o4-05

Capacitor Maintenance Setting

Sets the value from which to start the count for the main circuit capacitor maintenance period as a percentage.

o4-07

Softcharge Relay Maintenance Set

Sets as a percentage the value from which to start the count for the soft charge bypass relay maintenance time.

o4-09

IGBT Maintenance Setting

Sets the value from which to start the count for the IGBT maintenance period as a percentage.
