3-28 SB3000 Drive Configuration and Programming
Drive Fault Register (Continued) 202/1202
Charge Fault Bit 6
The Charge Fault bit is set if either of the
following has occurred: Hex Value: 0040H
Sug. Var. Name: FLT_CHG@
Access: Read only
UDC Error Code: 1024
LED: EXT FLT and
P.M. FLT
• the pre-charge contactor did not close when commanded to by the PMI
Processor, or
• the contactor opened without being commanded to do so.
Overtemperature Fault Bit 7
The Overtemperature Fault bit is set if the
fault level thermal switch in the power
module opens. Hex Value: 0080H
Sug. Var. Name: FLT_OT@
Access: Read only
UDC Error Code: 1016
LED: P.M. FLT
If power modules are connected in parallel, bit 12 is set in register 204/1204,
220/1220, or 221/1221 to indicate which GDI detected the fault.
Power Loss Fault Bit 10
The Power Loss Fault bit is set if the AC
input voltage is less than 75%, or more than
125%, of the configured value for more than
ten seconds while the Rectifier is running. Hex Value: 0400H
Sug. Var. Name: FLT_PWR@
Access: Read only
UDC Error Code: 1025
LED: EXT FLT
A drive warning (WRN_PWR@) will be issued, and the power dip ride-through
feature of the SB3000 will be enabled, for ten seconds prior to the drive fault. See
the description of register 203/1203, bit 10, for further information.
This bit will also be set if one phase of the AC line is lost or if line synchronization is
lost.
Power Technology Fault Bit 11
The Power Technology Fault bit is set if the
Rectifier’s AC Power Technology module
fails. Hex Value: 0800H
Sug. Var. Name: FLT_PTM@
Access: Read only
UDC Error Code: 1011
LED: OK on PWR
TECH Module
Register 222/1222 provides additional diagnostics if this fault occurs.
