Description
Determines how constant speeds are selected, and whether
the rotation direction signal is considered or not when
applying a constant speed.
Information
1 = Packed: 7 constant speeds are selectable using the three sources
defined by parameters 22.22,
0 = Separate: Constant speeds 1, 2 and 3 are separately activated by
the sources defined by parameters 22.22,
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
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).
