Function:
[0 - 110000 Enter the low frequency limit
Hz] 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.
Function:
[0 - 110000 Enter the high frequency limit
Hz] corresponding to the high motor shaft
speed (i.e. high reference value) in
parameter 5-53 Term. 29 High Ref./Feedb.
Value.
Function:
[-999999.999 - Enter the low reference

terminal 29 to digital input
(parameter 5-02 Terminal 29
Mode = [0] input (default)
and parameter 5-13 Terminal
29 Digital Input = applicable
value).
Function:
[-999999.999 - Enter the high reference value
999999.999 [RPM] for the motor shaft speed
ReferenceFeed- and the high feedback value, see

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).
Function:
[1 - 1000 Enter the pulse filter time constant. The
ms] 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
