Fault/Alarm Description
HtSink DS temp hot
Diode source heatsink temperature (variable DS heat
sink temp) is high.
HtSink DS over temp Diode source heatsink temperature (variable DS heat
sink temp) is too high.
HtSink DS rise high Diode source heatsink temperature (variable DS heat
sink temp) is too far above ambient temperature
(variable Bridge ambient temp).
HtSink DS temp low
Diode source heatsink temperature (variable DS heat
sink temp) is too low.
HtSink temp imbalanc Trip fault occurs when any two of the measured heatsink
temperatures differ by an amount exceeding heatsink
imbalance fault level.
HtSink blower failed Trip fault occurs if the drive is running and the cooling
fans are not operating.
BICM card temp low
Control rack temperature, measured by a sensor on
BICM, is too low.
BICM card hot
Control rack temperature, measured by a sensor on
BICM, is high.
BICM card over temp Control rack temperature, measured by a sensor on
BICM, is too high.
Line-Line Voltage Protection
The drive contains several diagnostic and protective features involving the Line-Line
Voltage Protection.
Diagnostic variables
The following table specifies the Line-Line Voltage Protection diagnostic variables.
Variable Description
Output volts, A-B Filtered A-B line-line voltage. Line-line volts
Output volts, B-C Filtered B-C line-line voltage. Line-line volts
A-B, Voltage offset Calculated A-B voltage offset. Line-line volts
B-C, Voltage offset Calculated B-C voltage offset. Line-line volts
Faults and alarms
The following table specifies the faults and alarms associated with the Line-Line
Voltage Protection.
Fault/Alarm Description
A-B voltage offset
Trip fault that occurs when the A-B line-line voltage offset
is too high.
B-C voltage offset Trip fault that occurs when the B-C line-line voltage offset
is too high.
