MG.60.B1.02 - VLT is a registered Danfoss trade mark
Description of choice:
The upper signal limit, Ref
HIGH
,of the reference must
be programmed within the normal working range of
the frequency converter, provided parameter 100
Configuration
has been programmed for
Open loop
[0]. In
Closed loop
[1] (parameter 100), Ref
HIGH
must
be within the reference range programmed in
parameters 204 and 205.
227 Warning: Low feedback, FB
LOW
(WARN LOW FDBK)
Value:
-999,999.999 - FB
HIGH
(parameter 228)
★
-999.999,999
Function:
If the feedback signal is below the limit, FB
LOW,
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 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
, the unit for the feedback is
programmed in parameter 415
Process units
.
Description of choice:
Set the required value within the feedback range
(parameter 413
Minimum feedback, FB
MIN
,
and 414
Maximum feedback, FB
MAX
).
228 Warning: High feedback, FB
HIGH
(WARN. HIGH FDBK)
Value:
FB
LOW
(parameter 227) - 999,999.999
★
999.999,999
Function:
If the feedback signal is above the limit, FB
