Danfoss VLT 5000 Series Instruction Manual page 110

The signal outputs can be programmed to transmit a
status signal via terminal 42 or 45 and via relay output
01 or 04 (parameter 319, 321, 323 or 326).
Description of choice:
The lower signal limit of the motor frequency, f
to be programmed within the normal working range of
the adjustable frequency drive.
See drawing at parameter 223.
226 Warning: High frequency
(WARN. FREQ. HIGH)
Value:
parameter 225 - parameter 202
Function:
When the motor frequency is above the limit program-
med in this parameter, f , the display will indicate
HIGH
FREQUENCY HIGH.
The signal outputs can be programmed to transmit a
status signal via terminal 42 or 45 and via relay output
01 or 04 (parameter 319, 321, 323 or 326).
Description of choice:
The upper signal limit of the motor frequency, f
must be programmed within the normal working range
of the adjustable frequency drive.
See drawing at parameter 223.
227 Warning: Low feedback
(WARN. FEEDB. LOW)
Value:
-100,000.000 - parameter 228.
Function:
If the connected feedback signal gets below the value
set in this parameter, the signal outputs can be pro-
grammed to transmit a status signal via terminal 42 or
45 and via relay output 01 or 04 (parameter 319, 321,
323 or 326).
Description of choice:
Set the desired value.

228 Warning: High feedback
(WARN. FEEDB HIGH)
Value:
parameter 227 - 100,000.000
Function:
, is
LOW
If the connected feedback signal gets above the value
set in this parameter, the signal outputs can be pro-
grammed to transmit a status signal via terminal 42 or
45 and via relay output 01 or 04 (parameter 319, 321,
323 or 326).
Description of choice:
Set the desired value.
132.0 Hz
229 Frequency bypass, bandwidth
(FREQ BYPASS B.W.)
Value:
0 (OFF) - 100%
Function:
Some systems call for some output frequencies to be
avoided because of resonance problems in the sys-
tem.
In parameters 230-233 these output frequencies can
,
HIGH
be programmed for bypassing (Frequency bypass). In
this parameter (229), a bandwidth can be defined on
either side of these frequency bypasses.
The frequency bypass function is not active if par. 002
is set to Local and par. 013 is set to LCP ctrl/Open
loop or LCP+dig ctrl/Open loop.
Description of choice:
The bypass bandwidth is set as a percentage of the
bypass frequency which is selected in parameter
-4000.000
230-233.
The bypass bandwidth indicates max. variation of the
bypass frequency.
Example: A bypass frequency of 100 Hz and a bypass
bandwidth of 1% are selected. In this case the bypass
frequency can vary between 99.5 Hz and 100.5 Hz i.e.
1% of 100 Hz.
