4.7.5 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 act as frequency reference inputs. Set terminal 29 (parameter 5-13 Terminal 29
Digital Input) to [32] Pulse input. If terminal 29 is used as an input, set parameter 5-02 Terminal 29 Mode to [0] Input.
