Description: True
The system IGBT switches have been shut down.
False
The system IGBT switches are operating normally
This bit indicates that the system’s power switches have shut down to protect the operator
and the Danfoss Power Solutions controller.
During startup, the switches will not be turned on until High Voltage reaches a minimum
value.
The switches will be turned off if the High Voltage drops below a minimum value. When the
voltage rises above the minimum value, they will be turned back on. This will correspond
with “Under Voltage Warning” being set to true.
If this is the case, the switches will be turned back on when High Voltage exceeds the
minimum value and a restart is not required.
Otherwise: Power Switches Off will correspond to the following messages in the Event Log
(See the Danfoss Power Solutions User Manual for information on the Event Log).
