221 Current limit, I
LIM
(CURRENT LIMIT)
Value:
0 - XXX.X % of par. 105
Function:
In this parameter, the maximum output current I
is set. The factory-set value corresponds to the
maximum output current I
is to be used as motor protection, set the rated
motor current. If the current limit is set above 100%
(the rated output current of the frequency converter,
I ), the frequency converter can only handle a load

intermittently, i.e. for short periods at a time. After the
load has been higher than I
for a period the load is lower than I
if the current limit is set at a lower value than I
acceleration torque will be reduced to the same extent.
Description of choice:
Set the required maximum output current I
223 Warning: Low current, I
(WARN. CURRENT LO)
Value:
0.0 - par. 224 Warning: High current, I
Function:
If the output current falls below the preset
limit I a warning is gi v en.
LOW
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 acti v ated when the output frequency
has reached the resulting reference. The signal
outputs can be programmed to gi v e a warning signal
via terminal 46 and via the relay output.
Description of choice:
The lower signal limit of the output current I
must be programmed within the normal working
range of the frequency converter.

Parameters 223-228 Warning functions do not
work during ramp-up after a start command and

functions are acti v ated when the output frequency
has reached the resulting reference. The signal
outputs can be programmed to gi v e a warning signal

The output current's upper signal limit I

normal operating range. See drawing at parameter
