If the selected Event condition changes before the on- or
off delay timer expires, the relay output is unaffected.
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, then set
5-02 Terminal 29 Mode to [0] Input.

5-52 Term. 29 Low Ref./Feedb. Value.
Refer to the diagram in this section.
Function:
[0 - 110000 Enter the high frequency limit
Hz] corresponding to the high motor shaft
speed (i.e. high reference value) in
5-53 Term. 29 High Ref./Feedb. Value.
Function:
[-999999.999 - Enter the low reference value limit
999999.999 ] for the motor shaft speed [RPM].
This is also the lowest feedback
value, see also 5-57 Term. 33 Low
Ref./Feedb. Value.
Function:
[-999999.999 - Enter the high reference value
*
999999.999 ] [RPM] for the motor shaft speed
and the high feedback value,
see also 5-58 Term. 33 High Ref./
Feedb. Value.
Function:
[1 - 1000 Enter the pulse filter time constant. The
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.
Function:
[0 - 110000 Enter the low frequency
Hz] corresponding to the low motor shaft
speed (i.e. low reference value) in
5-57 Term. 33 Low Ref./Feedb. Value.
