214 Parameters
22.15 Speed additive 1
source Defines a reference to be added to the speed reference after
reference selection (see page
582 ).
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.
Zero
22.16 Speed share Defines a scaling factor for the selected speed reference
(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 .
1.000
-8.000 …8.000 Speed reference scaling factor. 1000 = 1
22.17 Speed additive 2
source Defines a reference to be added to the speed reference after
the speed share function (see page
582 ).
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.
Zero
22.21 Constant speed
function Determines how constant speeds are selected, and whether
the rotation direction signal is considered or not when
applying a constant speed. 0000b

Bit Name Information
0 Constant speed
mode 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.
1 Direction
enable 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 ).
