5-40 Function Relay
Array (Relay 1 [0], Relay 2 [1])
Select options to define 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
).

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].

The output is high when the
frequency converter is in
Auto on
mode (as indicated by the LED light
above [Auto on].

details. If the selected event
condition changes before a delay
timer expires, the relay output is
unaffected.

3.6.4 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
