230 Parameters
Selects a mathematical function between the reference
sources selected by parameters
and
. See diagram at
.
Ref1
is used as
frequency reference 1 as such (no function applied).
0
Add (ref1 + ref2)
The sum of the reference sources is used as frequency
reference 1.
1
Sub (ref1 - ref2)
The subtraction ([
] - [
]) of the reference sources is used as
frequency reference 1.
2
Mul (ref1 × ref2)
The multiplication of the reference sources is used as
frequency reference 1.
3
Min (ref1, ref2)
The smaller of the reference sources is used as frequency
reference 1.
4
Max (ref1, ref2)
The greater of the reference sources is used as frequency
reference 1.
5
Determines how constant frequencies are selected, and
whether the rotation direction signal is considered or not
when applying a constant frequency.

Const 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 speed, the
sign of the constant speed 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
speeds if all values in
…
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
…
