Siemens SINAMICS G120 - Fixed Speed Setpoint as Setpoint Source

6.16.4 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.
