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 dia-
gram 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:
1500.00
0
*
[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 sig-
nal 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.
2.8.7. 5-6* Pulse Outputs
Parameters for configuring the scaling and output functions of pulse outputs. The pulse outputs
are designated to terminals 27 or 29. Select terminal 27 output in par. 5-01 and terminal 29 output
in par. 5-02.
