Dual loop configurations
The motor speed control loop is closed on one feedback connected on the motor while the motor position
control loop is closed on the other available feedback which is placed on the load. There is usually a transmission
between the load and the motor.

Each defined motor type can have any combination of the supported feedbacks either on motor or on load.
Example:
-PMSM motor with Incremental encoder (from feedback #1) on motor and Incremental encoder (from feedback#2)
on load
-DC brush motor with SSI encoder (from feedback #2) on motor and Sin/Cos encoder (from feedback #1) on load.
