No.
Zero / uint32Defines a reference to be added to the speed reference
after reference selection (see page 624).
For the selections, see parameter 22.11 Speed ref1 source.
Note: For safety reasons, the additive is not applied when
any of the stop functions are active.

1.000 / real32Defines 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 22.14
Speed ref1/2 selection.

Zero / uint32Defines a reference to be added to the speed reference
after the speed share function (see page 624).
For the selections, see parameter 22.11 Speed ref1 source.
Note: For safety reasons, the additive is not applied when
any of the stop functions are active.
Speed additive 2
source
22.17
- / uint16Determines how constant speeds are selected, and
whether the rotation direction signal is considered or not
when applying a constant speed.
Constant speed
function
22.21
1 = Packed: 7 constant speeds are selectable using the
three sources defined by parameters 22.22, 22.23 and
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.
Constant speed modeb0
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 are positive.
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).
