Parameters
3018 COMM FAULT FUNC
Defines the drive response if the fieldbus communication is lost.
0 =
NOT SEL

1 =
FAULT
– Displays a fault (28,
SERIAL
1
ERR
) and the drive coasts to stop.
2 =
CONST SP
7 – Displays an alarm (2005,
I
/
O COMM
) and sets speed using 1208
CONST SPEED
7. This “alarm speed”
remains active until the fieldbus writes a new reference value.
3 =
LAST SPEED
– Displays an alarm (2005,
I
/
O COMM
) and sets speed using the last operating level. This value is the
average speed over the last 10 seconds. This “alarm speed” remains active until the fieldbus writes a new
reference value.
WARNING! If you select
CONST SP
7, or
LAST SPEED
, make sure that continued operation is safe when
fieldbus communication is lost.
