Low Warning Level
Low Fault Level
Offset from the expected Load line, 2 additional lines are calculated. These are the Warning and Fault detection thresholds. The deviation from
normal behavior is determined by the
Low Warning Level
and
Low Fault Level
parameters.
When running, the
Load Monitor State
diagnostic will show if the actual Load is in the NORMAL, WARNING or FAULT region of the graph. Note
– for this to report correctly, the
Low Fault Level
must be more negative than the
Low Warning Level
.
If the actual Load remains in the FAULT region for longer than the duration specified by
Fault Delay
, the Drive will stop running.
The
Start Delay
may be used to prevent incorrect warning or fault reported soon after the Run command is issued.
The
Load Monitor State
diagnostic is reset when the Run command is removed.
