Function:
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.

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 (parameter 5-13 Terminal 29 Digital
P 5-42
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:
[20 - Enter the low frequency limit

speed (that is low reference value) in
parameter 5-52 Term. 29 Low Ref./Feedb.
Value. See Illustration 3.9.
Function:
[21 - Enter the high frequency limit
32000 Hz] corresponding to the high motor shaft
speed (that is high reference value) in
parameter 5-53 Term. 29 High Ref./Feedb.
Value.
Function:
Enter the low reference value limit for the
motor shaft speed [RPM]. This is also the lowest
feedback value. Set terminal 29 to digital input
(parameter 5-13 Terminal 29 Digital Input =
applicable value).
