Contactor Status [Contactor Status]
Linear Number:
506
Access Level:
Service
Read/Write:
Read
Only
This parameter displays the status of the various contactors and their isolating switches configured with
the drive. A ‘1’ indicates that the contactor or the isolating switch is closed. This parameter is used by the
drive for protection. If a contactor has been commanded to close and is determined not to be closed, then
the drive will trip. Similarly depending on the
Operating Mode
of the drive, if the isolating switch status is
opposite to the expected then the drive will trip.

Only
This word indicates various status bits within the rectifier control. The word can be used in trending to
assist in determining what the rectifier control is doing in a normal or abnormal situation. A 1 in a location
indicates that condition is active, and a 0 indicates the condition is inactive.
