5-42 Off Delay, Relay
Array [8]
Range:
0.01 - 600.00 s.
Function:
Enter the delay of the relay cut-out time. Select
one of available mechanical relays and MCO 105
in an array function. See par. 5-40.
If the selected event condition changes
before the on or off delay timer expires, the
relay output is unaffected.
5-5* Pulse Input
"
The pulse input parameters are used to define
an appropriate window for the impulse reference
area by configuring the scaling and filter settings
for the pulse inputs. Input terminals 29 or 33
act as frequency reference inputs. Set terminal
29 (par. 5-13) or terminal 33 (par. 5-15) to
* default setting ( )

MG.33.B6.22 - VLT is a registered Danfoss trademark
Pulse input [32]. If terminal 29 is used as an
input, then set par. 5-01 to Input [0].
5-50 Term. 29 Low Frequency
Range:
100 - 110000 Hz
0.01s
Function:
Enter the low frequency limit corresponding to the
low motor shaft speed (i.e. low reference value) in
par. 5-52. Refer to the diagram in this section.
This parameter is available for FC 302 only.
5-51 Term. 29 High Frequency
Range:
0 - 110000 Hz
Function:
Enter the high frequency limit corresponding
to the high motor shaft speed (i.e. high
reference value) in par. 5-53.
This parameter is available for FC 302 only.
5-52 Term. 29 Low Ref./Feedb. Value
Range:
-1000000.000 - par. 5-53
Function:
Enter the low reference value limit for the motor
shaft speed [RPM]. This is also the lowest feedback
value, see also par. 5-57. Set terminal 29
to digital output (par. 5-02 =Output [1] and
par. 5-13 = applicable value).
This parameter is available for the FC 302 only.
