225 Warning: Low Reference
(WARN. LOW REF)
Value:
-999,999.999 - High Reference (par. 226) ★ -999,999.999 Hz
Function:
When the total remote reference is less than the limit programmed in this
parameter, the display shows a flashing REF. < REF. LOW
The reference limits in parameter 226, Warning: High Reference and
parameter 225, Warning: Low Reference are only active when remote
reference has been selected.
In Open Loop, the unit for the reference is Hz, while in Closed Loop
the unit is programmed in parameter 415, Process Units.
Description of choice:
When parameter 100, Configuration, has been programmed for Open
Loop, the lower signal limit of the reference must be programmed within
the normal working range of the drive. If parameter 100 is pro-
grammed as Closed Loop, Low Reference must be within the
reference range programmed in parameters 204 and 205.
226 Warning: High Reference
(WARN. HIGH REF)
Value:
Reference Low (par. 225) to 999,999.999 ★ 999,999.999 Hz
Function:
If the resulting reference is below the limit programmed in this param-
eter, the display flashes REF. > REF. HIGH.,
The reference limits in parameter 226 Warning: High Reference and
parameter 225 Warning: Low Reference are only active when remote
reference has been selected.
In Open Loop, the unit for the reference is Hz, while in Closed Loop
the unit is programmed in parameter 415, Process Units.
Description of choice:
The high reference warning must be programmed within the normal
working range of the drive, provided parameter 100 Configuration has
been programmed for Open Loop. If parameter 100 has been
programmed for Closed Loop, Reference High must be within the
reference range programmed in parameters 204 and 205.

227 Warning: Low Feedback
(WARN .LOW FDBK)
Value:
-999,999.999 to High Feedback (parameter 228)
Function:
If the feedback signal is below the limit of Low Feedback programmed
in this parameter, the display will flash FEEDBACK < FOB LOW.
The unit for feedback is programmed in parameter 415, Process Units.
Description of choice:
Set the desired value within the feedback range, parameter 413,
Minimum Feedback, and parameter 414, Maximum Feedback.
228 Warning: High Feedback
(WARN. HIGH FDBK)
Value:
Low Feedback (parameter 227) to 999,999.999
Function:
If the feedback signal is above the limit programmed in this parameter,
the display will show a flashing FEEDBACK > FOB HIGH.
The unit for feedback is programmed in parameter 415, Process Units.
Description of choice:
Set the required value within the feedback range, parameter 413,
Minimum Feedback, and parameter 414, Maximum Feedback.
