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 direct or binary fixed setpoint
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.
