D30
Axis
r=2, w=2
Main ref value source: The main reference value is set in D30. The following functions are
available: ref value external, correct ref1 and correct ref2, preset values, motorized pot, PID control
error and n-actual.
Selection can also be made via the binary signals main ref value 0 to 2. The main ref value select
signals take precedence over the setting in D30.
The arrangement of the functions in the D30 selection lets you switch between two functions with a
binary signal (e.g., ref value external > preset value with D118.0 main ref value 0, or ref value
external > correct ref2 with D118.2 main ref value 2).
0: Ref value external;
1: preset value;
2: correct ref1;
3: motorised pot;
4: correct ref2;
5: PID;
6: n-actual;

D31
Axis
r=2, w=2
Additional ref value source: An addition reference value is selected in D31. The additional
reference value is activated by changing the default setting 0:inactive to one of the reference value
functions. The following functions are available: ref value external, correct ref1 and correct ref2,
preset value and fixed value, motorized pot and PID control error.
The additional reference value can have an absolute or percental effect (in reference to D56) on the
main reference value.
0: inactive;
1: Ref value external;
2: preset value;
3: correct ref1;
4: motorised pot;
5: correct ref2;
6: PID;
7: fix value;

D32
Axis
r=2, w=2
Mode additional ref value: D32 determines whether the additional reference value (AS) is
added as an absolute value or as a percental value to the main reference value (HSW). When the
setting is 0:absolute, the calculation HSW + AS is used. When the selection 1:percentage is used,
the additional reference value refers to D56 and is weighted with the main reference value.
The total calculation is: HSW + HSW x AS / D56
0: absolute;
1: percental of D56;

D33
Axis
r=2, w=2
Factor ref value source: The multiplying reference value is selected in D33. The multiplying
reference value (MSW) is used to weight the main reference value (HSW) or the result of the
addition of main reference value and additional reference value (HSW + ASW). The following
functions are available for the multiplying reference value: ref value external, correct ref1 and
correct ref2, preset value and fixed value, motorized pot and PID control error.
For weighting, the multiplying reference value (MSW) is based on D56 and is then multiplied by the
main reference value (HSW) or main reference value + additional reference value (HSW + ASW):
HSW x MSW / D56 or (HSW + ASW) x MSW / D56
0: inactive;
