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 par.
5-53.
This parameter is available for FC 302 only.
5-52 Term. 29 Low Ref./Feedb. Value
Range:
Function:
0.000
*
[-1000000.000 - par. 5-53] Enter the low reference value limit for the motor shaft speed [RPM]. This is also the lowest feedback value, see
also par. 5-57. Set terminal 29 to digital output (par. 5-02 =
Output
[1] and par. 5-13 = applicable value).
This parameter is available for FC 302 only.
5-53 Term. 29 High Ref./Feedb. Value
Range:
Function:
1500.000
*
[Par. 5-52 -
1000000.000]
Enter the high reference value [RPM] for the motor shaft speed and the high feedback value, see also par.5-58.
Select terminal 29 as a digital output (par. 5-02 =
Output
[1] and par. 5-13 = 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 dampening 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:
100Hz
*
[0 - 110000 Hz]
Enter the low frequency corresponding to the low motor shaft speed (i.e. low reference value) in par. 5-57. Refer
to the diagram in this section.
5-56 Term. 33 High Frequency
Range:
Function:
100Hz
*
[0 - 110000 Hz]
Enter the high frequency corresponding to the high motor shaft speed (i.e. high reference value) in par. 5-58.
5-57 Term. 33 Low Ref./Feedb. Value
Range:
Function:
0.000
*
[-100000.000 – par. 5-58] Enter the low reference value [RPM] for the motor shaft speed. This is also the low feedback value, see also par.
5-52.
5-58 Term. 33 High Ref./Feedb. Value
Range:
Function:
1500.000
*
[Par. 5-57 -
100000.000]
Enter the high reference value [RPM] for the motor shaft speed. See also par. 5-53
Term. 29 High Ref./Feedb.
Value
.
5-59 Pulse Filter Time Constant #33
Range:
Function:
100 ms [1 - 1000 ms]
Enter the pulse filter time constant. 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 on noise in the system. This parameter cannot be adjusted
while the motor is running.
