Determines how constant frequencies are selected, and
whether the rotation direction signal is considered or not when
applying a constant frequency.

Constant freq
mode
1 = Packed: 7 constant frequencies are selectable using the three
sources defined by parameters
.
0 = Separate: Constant frequencies 1, 2 and 3 are separately activated
by the sources defined by parameters
and
respectively. In case of conflict, the constant frequency with the smaller
number takes priority.
1
Direction
enable
1 = Start dir: To determine running direction for a constant frequency, the
sign of the constant frequency setting (parameters
) is
multiplied by the direction signal (forward: +1, reverse: -1). This
effectively allows the drive to have 14 (7 forward, 7 reverse) constant
frequencies if all values in
are positive.
WARNING:
If the direction signal is reverse and the active
constant frequency 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 (parameters
