reference will be added to the remote-controlled ref-
erence.
If Slow down is active via a digital input, the percent-
age value in parameter 219 Catch up/Slow down
reference will be deducted from the remote-
controlled reference.
221
221 Current limit, I
LIM
(CURRENT LIMIT)
Value:
0 - XXX.X % of par. 105
✭ 160 %
Function:
In this parameter, the maximum output current I
LIM
is
set. The factory-set value corresponds to the maxi-
mum output current I
MAX
. If the current limit is to be
used as motor protection, set the rated motor cur-
rent. If the current limit is set above 100% (the rated
output current of the frequency converter, I
INV.
), the
frequency converter can only handle a load intermit-
tently, i.e. for 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
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.
Parameters 223-228 Warning functions are out of
function during ramp-up after a start command and
after a stop command or during stop.The warning
functions are activated when the output frequency
has reached the resulting reference. The signal out-
puts can be programmed to give a warning 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.

224 Warning: High current, I
HIGH
(WARN. CURRENT HI)
Value:
Par. 223 Warn.: Low current, I
LOW
-I
MAX
✭ I
MAX
Function:
If the output current exceeds the preset limit I
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
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
Warning: Low current, I
LOW

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
after stop command or during stop. The warning
functions are activated when the output frequency
has reached the resulting reference. The signal out-
