If the selected event condition changes before the on
delay or off delay timer expires, the relay output is
unaffected.
4.6.4 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 (parameter 5-13 Terminal 29 Digital
Input) or terminal 33 (parameter 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.

Function:
[0.01 - 600 s] Enter the delay of the relay cutout
time. Select 1 of 2 internal
mechanical relays in an array
function. See
parameter 5-40 Function Relay for
details. If the selected event
condition changes before a delay
timer expires, the relay output is
unaffected.

Function:
[0 - 110000 Enter the low frequency limit
Hz] corresponding to the low motor
shaft speed (that is low reference
value) in parameter 5-52 Term. 29
Low Ref./Feedb. Value. Refer to
Illustration 4.28.
Function:
[0 - 110000 Enter the high frequency limit
Hz] corresponding to the high motor
shaft speed (that is high reference
value) in parameter 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].

terminal 29 to digital input
(parameter 5-02 Terminal 29 Mode =
[0] input (default) and
parameter 5-13 Terminal 29 Digital
Input = applicable value).
Function:
[-999999.999 Enter the high reference value
- 999999.999 [RPM] for the motor shaft speed
Reference- and the high feedback value, see
FeedbackUnit] also parameter 5-58 Term. 33 High
Ref./Feedb. Value. Select terminal 29
as a digital input
(parameter 5-02 Terminal 29 Mode =
[0] input (default) and
parameter 5-13 Terminal 29 Digital
Input = applicable value).
Function:
[5 - 1000 Enter the pulse filter time constant. The
ms] pulse filter dampens oscillations of the
feedback signal. If there is much noise in
the system, this is an advantage. A high
time constant value results in better
dampening but also increases the time
delay through the filter.
