326 Parameters
50
50 Fieldbus adapter
(FBA) Fieldbus communication configuration.
See also chapter
Fieldbus control through a fieldbus adapter
(page 467 ).
50.01 FBA A enable Enables/disables communication between the drive and
fieldbus adapter A, and specifies the slot the adapter is
installed into. Disable
Disable Communication between drive and fieldbus adapter A
disabled. 0
Enable Communication between drive and fieldbus adapter A
enabled. The adapter is in slot 1. 1
50.02 FBA A comm loss
func Selects how the drive reacts upon a fieldbus communication
break. The time delay is defined by parameter
50.03 FBA A
comm loss t out .
No action
No action No action taken. 0
Fault Communication break detection active. Upon a
communication break, the drive trips on a
7510 FBA A
communication fault and coasts to a stop.
1
Last speed Communication break detection active. Upon a
communication break, the drive generates a warning (
A7C1
FBA A communication ) and freezes the speed to the level the
drive was operating at. The speed is determined on the basis
of actual speed using 850 ms low-pass filtering.
WARNING! Make sure that it is safe to continue
operation in case of a communication break.
2
Speed ref safe Communication break detection active. Upon a
communication break, the drive generates a warning (
A7C1
FBA A communication ) and sets the speed to the value
defined by parameter 22.41 Speed ref safe (or 28.41
Frequency ref safe when frequency reference is being used).
WARNING! Make sure that it is safe to continue
operation in case of a communication break.
3
Fault always Drive trips on 7510 FBA A communication . This occurs even
though no control is expected from the fieldbus.
4
Warning Drive generates an A7C1 FBA A communication warning.
This occurs even though no control is expected from the
fieldbus.
WARNING! Make sure that it is safe to continue
operation in case of a communication break.
5
50.03 FBA A comm loss t
out Defines the time delay before the action defined by parameter
50.02 FBA A comm loss func is taken. Time count starts when
the communication link fails to update the message.
