- / uint16 Determines how constant frequencies are selected,
and whether the rotation direction signal is considered
or not when applying a constant frequency. Constant frequency
function 28.21
1 = Packed: 7 constant frequencies are selectable using
the three sources defined by parameters
28.22 , 28.23
and 28.24 .
0 = Separate: Constant frequencies 1, 2 and 3 are
separately activated by the sources defined by
parameters
28.22 , 28.23 and 28.24 respectively. In case
of conflict, the constant frequency with the smaller
number takes priority.
Constant freq mode b0
1 = Start dir: To determine running direction for a
constant frequency, the sign of the constant frequency
setting (parameters
28.26 … 28.32 ) 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
28.26 … 28.32 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
28.26 … 28.32 ).
