221 Current limit, I
LIM
(CURRENT LIMIT)
Value:
0 - XXX.X % of par. 10 5
✭ 160 %
Function:
In this parameter, the maximum output current I
LIM
is set. The factory-set value corresponds to the
maximum output current I
MAX
. If the current limit
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
INV.
), the frequency c onverter can only handle a load
intermittently, 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 e xtent.
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.
Parameters 223-228 Wa rning 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
outputs 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
LOW
must be programmed within the normal working
range of the frequency converter.
224 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.
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 o utput 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
,awarningisgiven.
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 o utput frequency
has reached the resulting reference. The signal
