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.

Additional information about direct selection can be found in function diagram 3011 in the
List Manual.
