Programming
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 selected
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
parameter 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 frequency has reached the selected
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 225
Warning: Low reference, Ref
LOW
, are only active
when remote reference 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
Configuration has been programmed for Open loop
[0]. In Closed loop [1] (parameter 100), Ref
LOW
must be within 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
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.
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 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 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
stopped. The warning functions are activated when
the output frequency has reached the selected
reference. The signal outputs can be programmed
