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 the diagram in this section.
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:
[-999999.999 - Enter the low reference
999999.999 value limit for the motor
ReferenceFeed- shaft speed [RPM]. This is
backUnit] 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 =input [0] (default)
and 5-13 Terminal 29
Digital Input = applicable
value).
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. Select
terminal 29 as a digital
input (5-02 Terminal 29
Mode =input [0] (default)
and 5-13 Terminal 29 Digital
Input = applicable value).
This parameter is available
for FC 302 only.
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
damping, but also increases the time delay
through the filter. This parameter is available
for FC 302 only.
This parameter cannot be adjusted while the
motor is running.
Function:
Enter the low frequency
corresponding to the low motor shaft
speed (i.e., low reference value) in
5-57 Term. 33 Low Ref./Feedb. Value.
Function:
Enter the high frequency
corresponding to the high motor shaft
speed (i.e., high reference value) in
5-58 Term. 33 High Ref./Feedb. Value.
