Description
Drive generates an A7CA DDCS controller comm loss
warning and sets the speed to the speed defined by
parameter 22.41 Speed ref safe
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
WARNING!
Make sure that it is safe to continue operation
in case of a communication break.
Drive trips on 7581 DDCS controller comm
occurs even though no control is expected from the
external controller.
Drive generates an A7CA DDCS controller comm loss
warning. 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.
Selects the type and scaling of reference 1 received
from the external controller. The resulting value is
shown by 3.11 DDCS controller ref
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).
The scaling is defined by parameter
The scaling is defined by parameter
The scaling is defined by parameter
scaling.
Selects the type and scaling of reference 2 received
from the external controller. The resulting value is
shown by 3.12 DDCS controller ref
For the selections, see parameter
