Fixed speed as setpoint source

In many applications after switching on the motor, all that is needed is to run the motor at a
constant speed or to switch between different speeds.
Example: After it has been switched on, a conveyor belt only runs with two different
velocities.

Select fixed setpoint by direct or binary selection
The converter distinguishes between two methods for selecting the fixed setpoints:
1. Direct selection:
You set 4 different fixed setpoints. By adding one or more of the four fixed setpoints, up
to 16 different resulting setpoints are obtained.
Figure 6-25
Additional information about direct selection can be found in function diagram 3011 in the
