Danfoss VLT 2800 User Manual

short periods at a time. After the load has been higher
than I
INV.
, it must be ensured that for a period the load
is lower than I
INV.
Please note that if the current limit is
set at a lower value than I
INV.
, the acceleration torque
will be reduced to the same extent.
Description of choice:
Set the required maximum output current I
LIM
.
223
Warning: Low current, I
LOW
(warn. current lo)
Value:
0.0 - par. 224 Warning: High current, I
HIGH
0.0 A
Function:
If the output current falls below the preset limit I
LOW
a
warning is given.
The signal outputs can be programmed to give a warn-
ing signal via terminal 46 and via the relay output.
Description of choice:
The lower signal limit of the output current I
LAV
must
be programmed within the normal working range of the
frequency converter.

Warning: High current, I
HIGH
(warn. current hi)
Value:
0 - I
MAX
I
MAX
Function:
If the output current exceeds the preset limit I
HIGH
a
warning is given.
The warning functions are activated when the output
frequency has reached the resulting reference. The
signal outputs can be programmed 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

225
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

132.0 Hz
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.
