Chapter 9
Faults in the rectifier may be cleared, and the fault queue cleared by writing to
this parameter. After the operation is completed, the value of this parameter will
revert to Ready (0).
This value is copied to the inverter through a datalink to transmit rectifier faults
to the inverter. This parameter is part of inverter/rectifier communications. Do
not write to this parameter.
Accumulated hours that the rectifier had been powered up at the time of the
most recent drive powerup.
This parameter is used along with the rectifier fault timestamp parameters
(Fault n Time parameters below[244, 246, 248, 250]) to determine whether a
rectifier fault in the rectifier fault queue happened before or after the most recent
drive powerup.
This value rolls over to 0 after the drive has been powered on for more than the
maximum value shown.
