5-50 Term. 29 Low Frequency
Range: Function:
100 Hz* [0 - 110000
Hz]
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.
5-51 Term. 29 High Frequency
Range: Function:
100 Hz* [0 - 110000
Hz]
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.
5-52 Term. 29 Low Ref./Feedb. Value
Range: Function:
0.000 Reference-
FeedbackUnit*
[-999999.999 -
999999.999
ReferenceFeed-
backUnit]
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 =input [0] (default)
and 5-13 Terminal 29
Digital Input = applicable
value).
This parameter is
available for FC 302 only.
5-53 Term. 29 High Ref./Feedb. Value
Range: Function:
Application

[-999999.999 -
999999.999

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.

5-54 Pulse Filter Time Constant #29
Range: Function:
100
ms*
[1 -
1000 ms]
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.
5-55 Term. 33 Low Frequency
Range: Function:
100 Hz* [0 - 110000
Hz]
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.
5-56 Term. 33 High Frequency
Range: Function:
100 Hz* [0 - 110000
Hz]
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.
