Danfoss VLT FCD 330 Design Guide

VLT
®
FCD Series
puts 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 frequency f
LOW
must be programmed within the normal operating
range of the frequency converter. See drawing at
parameter 223 Warning: Low current, I
LOW
.
226
226 Warning: High frequency f
HIGH
(WARN.FREQ.HIGH)
Value:
Par. 200 Frequency range = 0-132 Hz [0]/[1].
par. 225 f
LOW
- 132 Hz
✭ 132.0 Hz
Par. 200 Frequency range = 0-1000 Hz [2]/[3].
par. 225 f
LOW
- 1000 Hz
✭ 132.0 Hz
Function:
If the output frequency exceeds the preset limit f
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.
Description of choice:
The output frequency’s upper signal limit f
HIGH
must
be programmed within the frequency converter’s nor-
mal operating range. See drawing at parameter 223
Warning: Low current, I
LOW
.
227
227 Warning: Low feedback, FB
LOW
(WARN.FEEDB. LOW)
Value:
-100,000.000 - par. 228 Warn.:FB
HIGH
✭ -4000.000
Function:
If the feedback signal falls below the preset limit
FB
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
has reached the resulting reference.The signal out-
puts can be programmed to give a warning signal
via terminal 46 and via the relay output.The unit for
feedback in Closed loop is programmed in parame-
ter 416 Process units.
Description of choice:
Set the required value within the feedback range
(parameter 414 Minimum feedback, FB
MIN
and 415
Maximum feedback, FB
MAX
).
228
228 Warning: High feedback, FB
HIGH
(WARN.FEEDB HIGH)
Value:
Par. 227 Warn.: FB
LOW
- 100,000.000
✭ 4000.000
Function:
If the feedback signal gets above the preset limit
FB
HIGH
, 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
has reached the resulting reference. The signal out-
puts can be programmed to give a warning signal
via terminal 46 and via the relay output. The unit for
feedback in Closed loop is programmed in parame-
ter 416 Process units.
Description of choice:
Set the required value within the feedback range
(parameter 414 Minimum feedback, FB
MIN
and 415
Maximum feedback, FB
MAX
).
229
229 Frequence bypass, bandwidth
(FREQ BYPASS B.W.)
Value:
0 (OFF) - 100 Hz
✭ 0Hz
Function:
Some systems call for some output frequencies to
be avoided because of mechanical resonance
problems in the system. In parameters 230-231 Fre-
quency bypass these output frequencies can be
programmed. In this parameter a bandwidth can be
defined on either side of these frequencies.
