FC 300 Design Guide
Function:
Sets the low frequency referring to low
reference value in par. 5-52 to correspond
to the crankshaft speed.
This parameter is only available in FC 302.
5-51 Term. 29 High Frequency
Range:
100 - 110000 Hz
Function:
Set the high frequency referring to high
reference value in par. 5-53 to correspond
to the crankshaft speed.
5-52 Term. 29 Low Ref./Feedb. Value
Range:
-1000000.000 - par. 5-53
Function:
Sets the lowest reference value [RPM] for the
crankshaft speed and the lowest feedback value.
Select terminal 29 as a digital output (par. 5-02
="Output" [1] and par. 5-13 = applicable value).
5-53 Term. 29 High Ref./Feedb. Value
Range:
Par. 5-52 - 1000000.000
Function:
Sets the highest reference value [RPM] for the
crankshaft speed and the highest feedback value.
Select terminal 29 as a digital output (par. 5-02
="Output" [1] and par. 5-13 = applicable value)
5-54 Pulse Filter Time Constant #29
Range:
1 - 1000 ms
Function:
The low-pass filter reduces the influence on and
dampens oscillations on the feedback signal from the
control. This is an advantage, e.g. if there is a great
amount of noise in the system. It is not possible to
set this parameter while the motor is running.
5-55 Term. 33 Low Frequency
Range:
100 - 110000 Hz

the crankshaft speed.
The low-pass filter reduces the influence on and
dampens oscillations on the feedback signal from the

amount of noise in the system. It is not possible to
set this parameter while the motor is running.
5-6* Pulse Outputs
"
The pulse outputs are designated to terminals
27 or 29. Select terminal 27 in par. 5-01
and terminal 29 in par. 5-02.
