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, analog 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. f
the current limit is set above 100% (the rated output
current of the variable frequency drive, I
INV.
), the variable
frequency drive 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
reaches 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 unit.
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.
