Drive generates an A7CA DDCS controller comm loss
warning and sets the speed to the speed defined by
parameter 22.41 Speed ref safe (or 28.41 Frequency ref
safe when frequency reference is being used). This only
occurs if control is expected from the external controller,
or if supervision is forced using parameter 60.65 DDCS
controller comm supervision force.
WARNING!
Make sure that it is safe to continue operation in
case of a communication break.

Drive trips on 7581 DDCS controller comm loss. This
occurs even though no control is expected from the external
controller.

Auto / uint16Selects the type and scaling of reference 1 received from
the external controller. The resulting value is shown by
3.11 DDCS controller ref 1.

0Type 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).
