221 Warning: Low current, I
LOW
(WARN. LOW CURR.)
Value:
0.0 - par. 222
Warning: High current I
HIGH
,
✭
0.0A
Function:
When the motor current is below the limit, I
LOW
,
programmed in this parameter, the display shows a
flashing CURRENT LOW, provided
Warning
[1] has
been selected in parameter 409
Function in case of
no load
. The AFD will trip if parameter 409
Function
in case of no load
has been selected as
Trip
[0].
The warning functions in parameters 221-228 are
not active during ramp-up after a start command,
ramp-down after a stop command or while
stopped. The warning functions are activated when
the output frequency has reached the resulting
reference. The signal outputs can be programmed
to generate a warning signal via terminal 42 or
45 and via the relay outputs.
Description of choice:
The lower signal limit I
LOW
must be programmed
within the normal working range of the AFD.
222 Warning: High current, I

Function:
If the motor current is above the limit, I
HIGH
,
programmed in this parameter, the display shows
a flashing CURRENT HIGH.
The warning functions in parameters 221-228 are
not active during ramp-up after a start command,
ramp-down after a stop command or while stopped.
The warning functions are activated when the output
frequency has reached the resulting reference.
The signal outputs can be programmed to
generate a warning signal via terminal 42 or
45 and via the relay outputs.
Description of choice:
The upper signal limit of the motor frequency, f
HIGH
,
must be programmed within the normal working
range of the AFD. See drawing at parameter

0.0 Hz
Function:
If the output frequency is below the limit, f
LOW
,
programmed in this parameter, the display will
show a flashing FREQUENCY LOW.
The warning functions in parameters 221-228 are
not active during ramp-up after a start command,
ramp-down after a stop command or while stopped.
The warning functions are activated when the output
frequency has reached the selected reference.
The signal outputs can be programmed to
generate a warning signal via terminal 42 or
45 and via the relay outputs.
Description of choice:
The lower signal limit of the motor frequency, f
