Selection No.
3 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.
Speed ref safe
4 Drive trips on 7581 DDCS controller comm loss . This
occurs even though no control is expected from the
external controller.
Fault always
5 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.
Warning
Auto / uint16 Selects the type and scaling of reference 1 received
from the external controller. The resulting value is
shown by
3.11 DDCS controller ref 1 .
DDCS controller ref1
type 60.60
0 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).
Auto
1 No scaling is applied. Auto
2 Generic reference with a scaling of 100 = 1 (ie. integer
and two decimals). Auto
3 The scaling is defined by parameter 46.3 Torque scaling . Torque
4 The scaling is defined by parameter 46.1 Speed scaling . Speed
5 The scaling is defined by parameter 46.2 Frequency
scaling .

Auto / uint16 Selects the type and scaling of reference 2 received
from the external controller. The resulting value is
shown by
3.12 DDCS controller ref 2 .
For the selections, see parameter 60.60 DDCS controller
ref1 type .
DDCS controller ref2
type 60.61
Auto / uint16 Selects the type/source and scaling of actual value
ACT1 transmitted to the external controller. DDCS controller act1
