Parameters 207
Selects Ext2 speed reference source 2.
For the selections, and a diagram of reference source
selection, see parameter
.
Selects a mathematical function between the reference
sources selected by parameters
and
.
Ref1
is used as speed
reference 1 as such (no function applied).
0
Add (ref1 + ref2)
The sum of the reference sources is used as speed reference
1.
1
Sub (ref1 - ref2)
The subtraction ([
] - [
]) of the reference sources is used as speed reference 1.
2
Mul (ref1 × ref2)
The multiplication of the reference sources is used as speed
reference 1.
3
Min (ref1, ref2)
The smaller of the reference sources is used as speed
reference 1.
4
Max (ref1, ref2)
The greater of the reference sources is used as speed
reference 1.
5
Determines how constant speeds are selected, and whether
the rotation direction signal is considered or not when
applying a constant speed.

Constant speed
mode
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
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
).
