Low feedback
(WARN LOW FDBK)
Value:
-999,999.999 - FB
HIGH
(parameter 228)
✭
-999.999,999
Function:
If the feedback signal is below the limit programmed
in this parameter, the display will show a
flashing FEEDBACK LOW.
The warning functions in parameters 221-228
are not active during ramp up after a start
command, ramp down after a stop command
or while stopped. The warning functions are
activated when the output frequency has reached
the resulting reference. The signal output can
be programmed to generate a warning signal via
terminal 42 or 45 or via the relay output.
In
Closed loop
, the unit for the feedback is programmed
in parameter 415,
Units related to closed loop
.
Description of choice:
Set the desired value within the feedback range
between parameter 413,
Minimum Feedback
and
parameter 414,
Maximum Feedback
.

(parameter 227) - 999,999.999
✭
-999.999,999
Function:
If the feedback signal is above the limit programmed
in this parameter, the display will show a
flashing FEEDBACK HIGH.
The warning functions in parameters 221-228 are
not active during ramp-up after a start command,
ramp-down after a stop command or while
stop-ped. The warning functions are activated when
the output frequency has reached the resulting
reference. The signal outputs can be programmed
to generate a warning signal via terminal 42 or
45 and via the relay outputs.
In
Closed loop

Description of choice:
Set the desired value within the feedback range

-999.999,999
Function:
The
Minimum Reference
sets the minimum value
of the sum of all references. If
Closed loop
has
been selected in parameter 100,
Configuration
,
the minimum reference is limited by parameter
413,
Minimum Feedback
. Minimum reference is
ignored when the local reference is active. In
this case, minimum reference is determined by
parameter 201,
Minimum Frequency
.
Description of choice:
Set the
Minimum Reference
, which is the lowest
reference value that can be set for the drive. The
unit for this reference is set in parameter 415.

Function:
The
Maximum reference
gives the maximum value
that can be assumed by the sum of all references.
The
Maximum Reference
is limited to be with the
settings of Parameter 414
Maximum Feedback
.
The
Maximum reference
is ignored when the local
reference is active (parameter 203
Reference site
).
Description of choice:
Set the
Maximum reference
, which is the highest
reference value that can be set for the drive.
