2-14 Parameter Descriptions
7000-TD002A-EN-P – September 2007
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.
Bit Enum Text Description
0 Input IsoSw Status of Input Isolation Switch
1 Input Ctctr Status of Input Contactor
2 Output IsoSw Status of Output Isolation Switch
3 Output Ctctr Status of Output Contactor
4 Bypass IsoSw Status of Bypass Isolation Switch
5 Bypass Ctctr Status of Bypass Contactor
6 Not Used
7 Not Used
Rectifier Control Flag 1 [RecControl Flag1]
Linear Number: 264
Access Level: Service
Read/Write: Read 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.
Bit Enum Text Description
0 PLL Locked Rectifier Synchronized with the Line Voltage
1 PLL Enabled Input Voltage sufficient to attempt to lock onto the Line Voltage
2 Continuous DC link current is continuous
3 Rvs Sequence The incoming line is not UVW
4 Slave Swap The Slave 1 and Slave 2 Bridges are Swapped (18P only)
5 Phasing OK The drive has no phasing problems
6 MV Isolated There is no MV on the input to the rectifier
7 RecAnlgTstDn Rectifier Analog self tests completed
8 Rec Init Boot-Up on Rectifier is complete
9 Line Loss There is a line loss condition present
