module
PMI Read/Write Fault Bit 13
The PMI Read/Write Fault bit is set if a PMI
Processor read or write operation fails. Hex Value: 2000H
Sug. Var. Name: FLT_RW@
Access: Read only
UDC Error Code: 1013
LED: N/A
UDC Run Fault Bit 14
The UDC Run Fault bit is set if the UDC task
stops while the voltage loop is running in the
PMI Regulator. Hex Value: 4000H
Sug. Var. Name: FLT_RUN@
Access: Read only
UDC Error Code: 1014
LED: N/A
Communication Lost Fault Bit 15
The Communication Lost Fault bit is set if
the fiber-optic communication between the
Rectifier’s PMI Processor and the UDC
module is lost due to two consecutive errors
of any type. Hex Value: 8000H
Sug. Var. Name: FLT_COM@
Access: Read only
UDC Error Code: 1015
LED: COMM OK
This bit is set only after communication between the PMI Regulator and UDC
module has been established. This bit should be used in the run permissive logic for
the Rectifier. Also refer to the CCLK Synchronized bit (register 200/1200, bit 14).
