3.6.5 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
P 5-42
terminal 33 (5-15 Terminal 33 Digital Input) to [32] Pulse
input. If terminal 29 is used as an input, set 5-01 Terminal
27 Mode to [0] Input.
