Related Drive Parameters
Use parameters o4-03, o4-05, o4-07, and o4-09 to reset a Maintenance Monitor to zero after replacing a specific
component.
NOTICE: 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.
