Chapter 2 Faults and Troubleshooting Innovation Series Medium Voltage GP Type - G Drives GEH-6385
No. Name Type Description
42
DC bus under
voltage
Trip
The DC bus under voltage trip fault occurs when the DC link voltage feedback
(variable DC bus voltage) is too low.
The trip fault only occurs when the drive is running.
Possible board failures:
FOSA
DSPX
43 Ground flt alm, LP Alarm The Ground flt alm, LP alarm occurs when a large ground current is detected
by the BICM Motor Ground Protection.
The alarm occurs when the BICM ground current (variable Gnd cur signal) is
greater than the BICM ground current alarm level (parameter Gnd signal alarm
on).
Ground flt alm, LP clears when the BICM ground current drops below the
BICM ground current alarm turn off level (parameter Gnd signal alarm off).
The alarm can be disabled by inhibiting BICM Motor Ground Protection
functionality. Set parameter Detector mode equal to Disable.
Possible configuration faults:
The value of the BICM ground current alarm level, represented by parameter
Gnd signal alarm on, is too low.
Possible board failures:
VATF-MID
FOSA
BICM
DSPX
44 Ground flt, LP Trip
The Ground flt, LP trip fault occurs when a large ground current is detected by
the BICM Motor Ground Protection.
The trip fault occurs when the BICM ground current (variable Gnd cur signal)
is greater than the BICM ground current trip fault level (parameter Gnd signal
trip lvl).
Ground flt, LP can be disabled by inhibiting BICM Motor Ground Protection
functionality. Set parameter Detector mode equal to Disable.
Possible configuration faults:
The value of the BICM ground current fault threshold, represented by
parameter Gnd signal trip lvl, is too low.
Possible board failures:
VATF-MID
FOSA
BICM
DSPX
45 AC filter fuse blown Alarm The AC filter fuse blown alarm occurs when the BICM Motor Ground
Protection detects that the MOV fuse has blown. The trip fault occurs when
the BICM fuse circuit is open.
AC filter fuse blown can be disabled by inhibiting BICM Motor Ground
Protection functionality. Set parameter Detector mode equal to Disable.
Possible board failures:
VATF-MID
FOSA
BICM
DSPX
