The direction of rotation can be activated by assigning terminal „F“ (forward X1.10) or
„R“ (reverse X1.11), If both terminals are assigned simultaneously then the direction
of rotation „forward“ has priority.
Connection / activation of direction of rotation see Chapter 6.3 „Digital In- and Out-
puts“
.
The direction of rotation can be defined by the adjusted set value signal. For analog
singals through adjustment of positive or negative voltages. For digital signals through
adjustment of positive (without sign) or negative values (negative sign in the display).
For the factory setting apply following rules:
Set value 0 -> Rotation forward (F
set
=0Hz)
Positive value -> Rotation forward
Negative value -> Rotation reverse
With parameter di.20 the adjustment of direction of rotation can be adapted to special
applications.
