5-59 Pulse Filter Time Constant #33
Range:
100 ms [1 - 1000 ms]
76
Function:
Enter the high frequency limit corresponding to the high motor shaft speed (i.e. high reference value) in par.
5-53.
Function:
Enter the low reference value limit for the motor shaft speed [RPM]. This is also the lowest feedback value, see
also par. 5-57.
Function:
Function:
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 cannot be adjusted while the motor is running.
Function:
Enter the low frequency corresponding to the low motor shaft speed (i.e. low reference value) in par. 5-57.
Function:
Enter the high frequency corresponding to the high motor shaft speed (i.e. high reference value) in par. 5-58.
Function:
Enter the low reference value [RPM] for the motor shaft speed. This is also the low feedback value, see also par.
5-52.
Function:
Value .
Function:
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.
