Parameters 345
Last speed
Drive generates an
warning and
freezes the speed to the level the drive was operating at. This
only occurs if control is expected from the FBA A interface, or
if supervision is forced using parameter
.
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 an
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 FBA A
interface, or if supervision is forced using parameter
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 FBA A interface.
4
Warning
Drive generates an
warning.
This only occurs if control is expected from the FBA A
interface, or if supervision is forced using parameter
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.
As a rule of thumb, this parameter should be set to at least 3
times the transmit interval of the master.
Note:
There is a 60-second boot-up delay immediately after
power-up. During the delay, the communication break
monitoring is disabled (but communication itself can be
active).
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.
Note:
Fieldbus-specific communication profiles may use
different scalings. For more information, see the manual of the
fieldbus adapter.
Auto
Type and scaling are chosen automatically according to which
reference chain (see settings
) the
incoming reference is connected to. If the reference is not
connected to any chain, no scaling is applied (as with setting
0
Transparent
No scaling is applied (the 16-bit scaling is 1 = 1 unit).
1
General
Generic reference with a 16-bit scaling of 100 = 1 (ie. integer
and two decimals).
2
Torque
The scaling is defined by parameter
.
3
Speed
The scaling is defined by parameter
4
Frequency
The scaling is defined by parameter
. 5
No.
