Description
Drive generates an A7C1 FBA A communication
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.

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.
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.
Generic reference with a scaling of 100 = 1 (ie. integer and
two decimals).

Selects the type/source and scaling of actual value 1
transmitted to the fieldbus network through fieldbus adapter
A.
Note: Fieldbus-specific communication profiles may use
different scalings. For more information, see the manual of
the fieldbus adapter.
