5-42 Off Delay, Relay
Array[20]
Range:
Function:
0.01 s
*
[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.

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
.

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