Description
The smaller of the reference sources is used as speed
reference 1.
The greater of the reference sources is used as speed
reference 1.
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
0 = Separate: Constant speeds 1, 2 and 3 are separately activated by
the sources defined by parameters
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
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 = According to Par: The running direction for the constant
frequency is determined by the sign of the constant speed setting
