219 Catch up/ Slow down reference
(CATCH UP/SLW DWN)
Value:
0.00 - 100% of the given reference
✭ 0.00%
Function:
In this parameter, the percentage value can be
set which will either be added to or deducted
from the remote-controlled references.
The remote-controlled reference is the sum of preset
references, analogue references, pulse reference and
any references from serial communication.
Description of choice:
If Catch up is active via a digital input, the percentage
value in parameter 219 Catch up/Slow down reference
will be added to the remote-controlled reference.
If Slow down is active via a digital input, the percentage
value in parameter 219 Catch up/Slow down reference
will be deducted from the remote-controlled reference.
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
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 converter 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 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.
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
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 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 draw
ing at parameter
223 Warning: Low current, I
LOW
.
