217 Frequency bypass 1
(BYPASS FREQ. 1)
218 Frequency bypass 2
(BYPASS FREQ. 2)
219 Frequency bypass 3
(BYPASS FREQ. 3)
220 Frequency bypass 4
(BYPASS FREQ. 4)
Value:
0 - 120/1000 HZ
✭ 120.0 Hz
The frequency range depends on the selection made
in parameter 200 Output frequency range.
Function:
Some systems call for some output frequencies
to be avoided because of mechanical resonance
problems in the system.
Description of choice:
Enter the frequencies to be avoided.
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 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
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 frequency converter.
222 Warning: High current, I
HIGH
(WARN. HIGH CURR.)
Value:
Parameter 221 - I
VLT,MAX
✭ I
VLT,MAX
Function:
Ifthemotorcurrentisabovethelimit,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.
