Function:
[0 - 110000 Enter the low frequency limit
corresponding to the low motor
shaft speed (that is low reference
value) in parameter 5-52 Term. 29
Low Ref./Feedb. Value. Refer to
Illustration 3.39.
Function:
[0 - 110000 Enter the high frequency limit
corresponding to the high motor
shaft speed (that is high reference
value) in parameter 5-53 Term. 29
High Ref./Feedb. Value.
Function:
[-999999.999 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.

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
[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

Function:
as a digital input
(parameter 5-02 Terminal 29 Mode =
[0] input (default) and
parameter 5-13 Terminal 29 Digital
Input = applicable value).
This parameter is available for FC
302 only.
Function:
[1 - 1000 ms] Enter the pulse filter time constant.
The pulse filter dampens
oscillations of the feedback signal, if
there is much noise in the system
this is an advantage. A high time
constant value results in better
dampening but also increases the
time delay through the filter.
Function:
[0 - 110000 Enter the low frequency
Hz] corresponding to the low motor
shaft speed (that is low reference
value) in parameter 5-57 Term. 33
Low Ref./Feedb. Value.
Function:
[0 - 110000 Enter the high frequency
Hz] corresponding to the high motor
shaft speed (that is high reference
value) in parameter 5-58 Term. 33
High Ref./Feedb. Value.
Function:
[-999999.999 Enter the low reference value [RPM]
- 999999.999 for the motor shaft speed. This is

Function:
[-999999.999 Enter the high reference value
