shaft speed [RPM]. This is
also the lowest feedback
value, see also

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, 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.
5-55 Term. 33 Low Frequency
Range:
Function:
100 Hz
*
[0 - 110000
Hz]
Enter the low frequency corresponding
to the low motor shaft speed (that is
low reference value) in
