Defines a reference to be added to the speed reference
after reference selection (see page 744).
For the selections, see parameter
source.
Note: For safety reasons, the additive is not applied
when any of the stop functions are active.
Defines a scaling factor for the selected speed
referencec (speed reference 1 or 2, multiplied by the
defined value).
Speed reference 1 or 2 is selected by parameter
Speed ref1/2 selection.
Speed reference scaling factor.
Defines a reference to be added to the speed reference
after the speed share function (see page 744).
For the selections, see parameter
source.
Note: For safety reasons, the additive is not applied
when any of the stop functions are active.
Determines how constant speeds are selected, and
whether the rotation direction signal is considered or
not when applying a constant speed.
1 = Packed: 7 constant speeds are selectable using the
three sources defined by parameters 22.22,
22.24.
0 = Separate: Constant speeds 1, 2 and 3 are separately
activated by the sources defined by parameters 22.22,
22.23 and 22.24 respectively.
In case of conflict, the constant speed with the smaller
number takes priority.
1 = Start dir: To determine running direction for a
constant speed, the sign of the constant speed setting
(parameters 22.26...22.32) is multiplied by the direction
signal (forward: +1, reverse: -1). This effectively allows
the drive to have 14 (7 forward, 7 reverse) constant
speeds if all values in 22.26...22.32
WARNING!
If the direction signal is reverse and the active
constant speed is negative, the drive will run in
the forward direction.
0 = Accord Par: The running direction for the constant
speed is determined by the sign of the constant speed
setting (parameters 22.26...22.32).
