command or during stop. The warning functions are
activated when the output frequency has reached the
resulting reference. The signal outputs can be pro-
grammed to give a warning signal via terminal 46 and
via the relay output.
Description of choice:
The output current's upper signal limit I
HIGH
must be
programmed within the frequency converter's normal
operating range. See drawing at parameter 223 Warn-
ing: Low current, I
LOW
.

Warning: Low frequency, f
LOW
(warn.freq. low)
Value:
0.0 - par. 226
Warn.: High frequency, f
HIGH
0.0 Hz
Function:
If the output frequency falls below the preset limit
f
LOW
, a warning is given.
Parameters 223-228 Warning functions are out of
function during ramp-up after a start command and af-
ter stop command or during stop. The warning func-
tions are activated when the output frequency has
reached the resulting reference. The signal outputs
can be programmed to give a warning signal via ter-
minal 46 and via the relay output.
Description of choice:
The lower signal limit of the output frequency f
LOW
must
be programmed within the normal operating range of
the frequency converter. See drawing at parameter
223 Warning: Low current, I

Function:
If the output frequency exceeds the preset limit f
HIGH
a warning is given.
Parameters 223-228 Warning functions do not work
during ramp-up after a start command and after stop
command or during stop. The warning functions are
activated when the output frequency has reached the
resulting reference. The signal outputs can be pro-
grammed to give a warning signal via terminal 46 and
via the relay output.
Description of choice:
The output frequency's upper signal limit f
HIGH
must be
programmed within the frequency converter's normal
operating range. See drawing at parameter 223 Warn-
ing: Low current, I

Function:
If the feedback signal falls below the preset limit
FB
LOW
, a warning is given.
Parameters 223-228 Warning functions are out of
function during ramp-up after a start command and af-
ter a stop command or during stop. The warning func-
tions are activated when the output frequency has
reached the resulting reference.The signal outputs
can be programmed to give a warning signal via ter-
minal 46 and via the relay output.The unit for feedback
in Closed loop is programmed in parameter 416 Proc-
ess units.
Description of choice:
Set the required value within the feedback range (pa-
rameter 414 Minimum feedback, FB
MIN
and 415 Max-
imum feedback, FB
MAX
).

Function:
If the feedback signal gets above the preset limit

, a warning is given.
Parameters 223-228 Warning functions are out of
function during ramp-up after a start command and af-
ter a stop command or during stop. The warning func-
tions are activated when the output frequency has
reached the resulting reference. The signal outputs
can be programmed to give a warning signal via ter-
