26 Constant speeds Constant speed selection and values.
An active constant speed overrides the drive speed
reference. See also section
Constant speeds on page 68 .
26.01 Const speed func Determines how constant speeds are selected, and whether
the rotation direction signal is considered or not when
applying a constant speed.
No. Name/Value Description FbEq

Const speed
mode
1 = Packed: 7 constant speeds are selectable using the three sources
defined by parameters
26.02 , 26.03 and 26.04 .
0 = Separate: Constant speeds 1, 2 and 3 are separately activated by
the sources defined by parameters
26.02 , 26.03 and 26.04 respectively.
In case of conflict, the constant speed with the smaller number takes
priority.
1 Dir ena
1 = Start dir: To determine running direction for a constant speed, the
sign of the constant speed setting (parameters
26.06 … 26.12 ) is
multiplied by the direction signal (forward: +1, reverse: -1). For example,
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
26.06 … 26.12 ).
