Description
The drive trips on 7510 FBA A
occurs if control is expected from the FBA A interface (FBA A
selected as source of start/stop/reference in the currently
active control location), or if supervision is forced using
parameter 50.26 FBA A comm supervision
Drive generates an A7C1 FBA A communication
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
supervision force.
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.
Drive generates an A7C1 FBA A communication
sets the speed to the value defined by parameter
Speed ref safe (when speed reference is being used) or
28.41 Frequency ref safe
used). This only occurs if control is expected from the FBA A
interface, or if supervision is forced using parameter
FBA A comm supervision
WARNING! Make sure that it is safe to continue
operation in case of a communication break.
Drive trips on 7510 FBA A
though no control is expected from the FBA A interface.
Drive generates an A7C1 FBA A communication
This occurs even though no control is expected from the
fieldbus. This only occurs if control is expected from the FBA
A interface, or if supervision is forced using parameter
FBA A comm supervision
WARNING! Make sure that it is safe to continue
operation in case of a communication break.

As a rule of thumb, this parameter should be set to at least 3

Time delay.
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.
Type and scaling are chosen automatically according to
which reference chain (see settings Torque, Speed,
Frequency) the incoming reference is connected to. If the
reference is not connected to any chain, no scaling is applied
(as with setting Transparent).
No scaling is applied (the 16-bit scaling is 1 = 1 unit).
Generic reference with a scaling of 100 = 1 (ie. integer and
two decimals).
