A code that represents a rectifier fault. The codes appear in these parameters in
the order they occur. Fault 1 Code = the most recent fault.
The time between initial power up and the occurrence of the associated fault.
Can be compared to Power Up Marker for the time from the most recent power
up.
(Fault x Time – Power Up Marker) = the time difference to the most recent
power up. A negative value indicates a fault occurred before the most recent
power up. A positive value indicates a fault occurred after the most recent power
up.
Amount of time used to determine whether rectifier Instantaneous Overcurrent
(IOC) fault redirection is discontinued because too many rectifier IOC events
have occurred in too short a period of time.
Certain AC line events cause the drive to stop running because of the detection
of a rectifier IOC condition. IOC fault redirection is a mechanism that allows
rectifier IOC conditions to be reported as Input Current Imbalance faults
(fault 225) rather than as rectifier IOC faults (rectifier faults 12, 211, 212, 213).
The purpose of this mechanism is to allow external drive control equipment to
distinguish between faults caused by AC line events and faults caused by internal
drive conditions.
