Function:
Function:
Enter the low frequency limit
corresponding to the low motor shaft
speed (i.e. low reference value) in
5-52 Term. 29 Low Ref./Feedb. Value. Refer
to .
This parameter is available for FC 302
only.
Function:
Enter the high frequency limit
corresponding to the high motor shaft
speed (i.e. high reference value) in
5-53 Term. 29 High Ref./Feedb. Value.
This parameter is available for FC 302
only.
Function:
Enter the low reference value limit for
the motor shaft speed [RPM]. This is
also the lowest feedback value, see
also 5-57 Term. 33 Low Ref./Feedb.
Value. Set terminal 29 to digital input
(5-02 Terminal 29 Mode = [0] input
(default) and 5-13 Terminal 29 Digital
Input = applicable value).

5.1.1 Cascade CTL Option, 27-**

Cascade Control Option parameter group.
®
is a registered Danfoss trademark
Function:
This parameter is available for FC 302
only.
Function:
Enter the high reference value
[RPM] for the motor shaft speed
and the high feedback value, see
also 5-58 Term. 33 High Ref./Feedb.
Value.
Function:
Enter the pulse filter time constant. The
pulse filter dampens oscillations of the
feedback signal, which is an advantage, if
there is a lot of noise in the system. A high
time constant value results in better
dampening but also increases the time
delay through the filter.
Function:
Select the desired display output for
terminal 27.
Function:
terminal 27, corresponding to the
output variable selected in
5-60 Terminal 27 Pulse Output Variable.
