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
parameter 5-52 Term. 29 Low Ref./Feedb.
Value. Refer to the diagram in this section.
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
parameter 5-53 Term. 29 High Ref./Feedb.
Value.
5-52 Term. 29 Low Ref./Feedb. Value
Range: Function:
0 ReferenceFeed-

Enter the low reference
value limit for the motor
shaft speed [RPM]. This is
also the lowest feedback
value, see also
parameter 5-57 Term. 33 Low
Ref./Feedb. Value. Set
terminal 29 to digital input
(parameter 5-02 Terminal 29
Mode = [0] input (default)
and parameter 5-13 Terminal
29 Digital Input = applicable
value).

Enter the high reference value
[RPM] for the motor shaft speed
and the high feedback value, see
also parameter 5-58 Term. 33 High
Ref./Feedb. Value. Select terminal
29 as a digital input
(parameter 5-02 Terminal 29 Mode
= [0] input (default) and
parameter 5-13 Terminal 29 Digital
Input = applicable value).
5-54 Pulse Filter Time Constant #29
Range: Function:
100
ms*
[1 - 1000
ms]
Enter the pulse lter time constant. The
pulse lter 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
