Rockwell Automation 1756-DMF30 ControlLogix Drive Module - Manual (Page 340)

Publication 1756-UM522B-EN-P - February 2003
C-88 1756-DMF30 Specific Information
2124 Pwr DeviceStatus
Indicates which SCR has shorted or not firing. If an SCR is
shorted, bit 0 [SCR Fault] of parameter 2122 [MC Faults] will be
set. If an SCR is not firing correctly, bit 0 [BrdgNotFirng] of
parameter 2123 [MC Warnings]will be set.
For a regenerative drive, this parameter indicates the pair of
SCRs that has faulted. For a non-regenerative drive, this
parameter indicates the specific SCR that has faulted.
The bits of this parameters are set when a fault event is
detected. They stay latched until bit 19 [Clear Fault] of
parameter 152 [AppliedLogic Cmd] or bit 19 [Clr Drv Wrn] of
parameter 166 [Motor Ctrl Cmmd] is set. If the fault event
remains present, the identifying bit is set again. Default: 0000 0000 0000 0000

2125 Interlock Code
The PMI processor performs interlock tests in response to
parameter 2100 [Drive Ctrl Word]. If any of the diagnostics
fail the PMI processor sets the bit in parameter 2125 [Interlock
Code] that corresponds to the first failed diagnostic. The bit
stays latched until bit 19 [Clear Fault] of parameter 152
[Applied LogicCmd] or bit 19 [Clr Drv Wrn] of parameter 166
[Motor Ctrl CÌmd] is set. Refer to Reliance Electric publication
S-3001-1, Distributed Power System SD3000 Drive
Diagnostics, Troubleshooting and Start-Up Guidelines, for
information about the interlock diagnostics. Default: 0000 0000 0000 0000
