Fixed speed setpoint 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.

Selecting the fixed speed setpoint, either direct or binary
The inverter makes a distinction between two methods when selecting the fixed speed
setpoints:
Directly selecting a fixed speed setpoint
You set 4 different fixed speed setpoints. Up to 16 different setpoints are obtained by adding
one or several of the four fixed speed setpoints.
