Parameters 241
Last speed
Drive generates a warning (
) and
freezes the speed to the level the drive was operating at. This
only occurs if control is expected from the fieldbus.
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
Drive generates a warning (
) and
sets the speed to the value defined by parameter
(when speed reference is being used) or
(when frequency reference is being
used). This only occurs if control is expected from the
fieldbus.
WARNING!
Make sure that it is safe to continue
operation in case of a communication break.
3
Fault always
Drive trips on
. This occurs even
though no control is expected from the fieldbus.
4
Warning
warning.
This only occurs if control is expected from the fieldbus
.
WARNING!
Make sure that it is safe to continue
operation in case of a communication break.
5
Defines the time delay before the action defined by parameter
is taken. Time count starts when
the communication link fails to update the message.
0.3 s
0.3…6553.5 s
Time delay.
1 = 1 s
Selects the type and scaling of reference 1 received from
fieldbus adapter A. The scaling of the reference is defined by
parameters
…
, depending on which reference
type is selected by this parameter.
Speed or frequency Type and scaling is chosen automatically according to the
currently active operation mode as follows:
0
Transparent
No scaling is applied.

2
Reserved
3
