5-40 Function Relay
Array (Relay 1 [0], Relay 2 [1])
Select options to dene the function of the relays.
The selection of each mechanical relay is realized in an array
parameter.
Option: Function:
clockwise (the logical product of
the status bits running AND reverse).
[165] Local ref.
active
The output is high when
parameter 3-13 Reference Site=[2]
Local or when
parameter 3-13 Reference Site=[0]
Linked to hand auto at the same
time as the LCP is in [Hand on]
mode.
[166] Remote ref.
active
The output is high when
parameter 3-13 Reference Site is set
to [0] Linked to Hand / Auto or [1]
Remote, while the LCP is in Auto on
mode.
[167] Start
command
activ
The output is high when there is an
active start command (that is, via
digital input, bus connection, [Hand
on] or [Auto on], and no stop
command is active.
[168] Drive in hand
mode
The output is high when the
frequency converter is in Auto on
mode (as indicated by the LED light
above [Hand on].
[169] Drive in auto
mode
The output is high when the
frequency converter is in Auto on
mode (as indicated by the LED light
above [Auto on].
5-41 On Delay, Relay
Array [2], (Relay 1 [0], Relay 2 [1])
Range: Function:
0.01 s* [0 - 600 s] Enter the delay of the relay cut in
time. Select one of 2 internal
mechanical relays in an array
function. See
parameter 5-40 Function Relay for
details.

Array[2]: Relay1[0], Relay2[1]
Range: Function:
0.01 s* [0 - 600 s] Enter the delay of the relay cut out
time. Select one 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
unaected.

3.6.4 5-5* Pulse Input
The pulse input parameters are used to dene an
appropriate window for the impulse reference area by
conguring the scaling and lter 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
