Description
Selects a mathematical function between the reference
sources selected by parameters
22.19 Ext2 speed ref2. See diagram at
ref1.
Signal selected by Ext2 speed ref1
reference 1 as such (no function applied).
The sum of the reference sources is used as speed reference
1.
The subtraction ([22.11 Ext1 speed
ref2]) of the reference sources is used as speed reference 1.
The multiplication of the reference sources is used as speed
reference 1.
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 22.22,
0 = Separate: Constant speeds 1, 2 and 3 are separately activated by
the sources defined by parameters 22.22,
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 22.26...22.32) 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
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
22.26...22.32).
