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.

5-59 Pulse Filter Time Constant #33
Range: Function:
100 ms [1 - 1000 Enter the pulse filter time constant. The

ms] 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.
