Zero / uint32 Defines a reference to be added to the speed reference
after reference selection (see page
744 ).
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 1
source 22.15
1.000 / real32 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
22.14
Speed ref1/2 selection .
Speed share 22.16
1000 = 1 / 1000 = 1 Speed reference scaling factor. -8.000 ... 8.000
Zero / uint32 Defines a reference to be added to the speed reference
after the speed share function (see page
744 ).
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
- / uint16 Determines 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
mode b0
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 ).
