VLT® 7000 Booster
Programming
222 Warning: High current, I
HIGH
(WARN. HIGH CURR.)
Value:
Parameter 221 - I
VLT,MAX
✭
I
VLT,MAX
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 frequency converter. See drawing at
parameter 221 Warning: Low current, I
LOW
.
223 Warning: Low frequency, f
LOW
(WARN. LOW FREQ.)
Value:
0.0 - parameter 224
✭
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
LOW
,
must be programmed within the normal working
range of the frequency converter. See drawing at
parameter 221 Warning: Low current, I
LOW
.
224 Warning: High frequency , f
HIGH
(WARN. HIGH FREQ.)
Value:
Par. 200 Output frequency range = 0-120 Hz [0].
parameter 223 - 120 Hz
✭
120.0 Hz
Par. 200 Output frequency range = 0-1000 Hz [1].
parameter 223 - 1000 Hz
✭
120.0 Hz
Function:
If the output frequency is above the limit, f
HIGH
,
programmed in this parameter, the display will
show a flashing FREQUENCY 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 higher signal limit of the motor frequency, f
HIGH
,
must be programmed within the normal working
range of the frequency converter. See drawing at
pa-rameter 221 Warning: Low current, I
LOW
.
225 Warning: Low reference, REF
LOW
(WARN. LOW REF.)
Value:
-999,999.999 - REF
HIGH
(par.226)
✭
-999,999.999
Function:
When the remote reference lies under the limit,
Ref
LOW
, programmed in this parameter, the display
shows a flashing REFERENCE LOW.
The warning functions in parameters 221-228 are
not active during ramp-up after a start command,
