221 Warning: Low current, I
(WARN. LOW CURR.)
Value:
0.0 - par. 222 Warning: High current, I
Function:
When the motor current is below the limit, I
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 VLT frequency converter 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 stop-ped. 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 must be programmed within
LOW
the normal working range of the frequency converter.

222 Warning: High current, I
(WARN. HIGH CURR.)
Value:
Parameter 221 - I
VLT,MAX
Function:
If the motor current is above the limit, I
grammed 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 stop-ped. 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
must be programmed within the normal working
range of the frequency converter. See drawing at
parameter 221 Warning: Low current, I
223 Warning: Low frequency, f
(WARN. LOW FREQ.)
Value:
0.0 - parameter 224
Function:
If the output frequency is below the limit, f
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 stop-ped. 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 of the motor frequency, f
must be programmed within the normal working
range of the frequency converter. See drawing at
