Danfoss VLT 6000 HVAC Series User Manual

Par. 200 Output frequency range =
0-1000 Hz [1].
parameter 223 - 1000 Hz
120.0 Hz
Function:
If the output frequency is above the limit, f
HIGH
, pro-
grammed in this parameter, the display will show a
flashing FREQUENCY 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 stopped. The
warning functions are activated when the output fre-
quency 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.
Description of choice:
The higher signal limit of the motor frequency, f
HIGH
,
must be programmed within the normal working range
of the frequency converter. See drawing at pa-rameter
221 Warning: Low current, I
LOW
.
225
Warning: Low reference, REF
LOW
(WARN. LOW REF.)
Value:
-999,999.999 - REF
HIGH
(par.
226)
-999,999.999
Function:
When the remote reference lies under the limit,
Ref
LOW
, programmed in this parameter, the display
shows a flashing REFERENCE 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 fre-
quency has reached the selected reference. The sig-
nal outputs can be programmed to generate a warning
signal via terminal 42 or 45 and via the relay outputs.
The reference limits in parameter 226 Warning: High
reference, Ref
HIGH
, and in parameter 225 Warning: Low
reference, Ref
LOW
, are only active when remote refer-
ence has been selected.
In Open loop mode the unit for the reference is Hz,
while in Closed loop mode the unit is programmed in
parameter 415 Process units.
Description of choice:
The lower signal limit, Ref
LOW
, of the reference must
be programmed within the normal working range of the
frequency converter, provided parameter 100 Config-
uration has been programmed for Open loop [0]. In
Closed loop [1] (parameter 100), Ref
LOW
must be with-
in the reference range programmed in parameters 204
and 205.
226
Warning: High reference , REF
HIGH
(WARN. HIGH REF.)
Value:
REF
Low
(par. 225) - 999,999.999
999,999.999
Function:
If the resulting reference is above the limit, Ref
HIGH
,
programmed in this parameter, the display shows a
flashing REFERENCE 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 stopped. The
warning functions are activated when the output fre-
quency 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.
The reference limits in parameter 226 Warning: High
reference, Ref
HIGH
, and in parameter 227 Warning: Low
reference, Ref
LOW
, are only active when remote refer-
ence 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 upper signal limit, Ref
HIGH
, of the reference must
be programmed within the normal working range of the
frequency converter, provided parameter 100 Config-
uration 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
, pro-
grammed in this parameter, the display will show a
flashing FEEDBACK LOW.
