Parameter Descriptions
3.7.5 5-5* Pulse Input
The pulse input parameters are used to define an
appropriate window for the impulse reference area by
configuring the scaling and filter settings for the pulse
inputs. Input terminals 29 or 33 act as frequency reference
inputs. Set terminal 29 (5-13 Terminal 29 Digital Input) or
terminal 33 (5-15 Terminal 33 Digital Input) to [32] Pulse
input. If terminal 29 is used as an input, set
parameter 5-01 Terminal 27 Mode to [0] Input.

5-54 Pulse Filter Time Constant #29
Range: Function:
100 [1 - 1000 Enter the pulse filter time constant. The
ms ms] 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.
